DevOps for Oracle Apps: 10 E-business Suite edifice information | real Questions and Pass4sure dumps

probably the most helpful construction techniques are tailor-made to the enterprise and product IT groups are working with. probably the most effectual groups enhance standardized techniques that champion carve back mistakes and velocity up the software birth lifecycle while expanding efficiency for their selected product.

DevOps spans americans, system, and know-how, and may subsist integrated into every IT group. mixed with most trustworthy practices for each and every team’s technical landscape, it might probably create more effectual tactics that deliver high-quality application to market in less time.

That’s very suitable for IT teams engaged on Oracle apps corresponding to E-business Suite. Combining DevOps practices with inescapable edifice tips for E-business Suite will accomplish complete groups greater valuable and bear more desirable consequences for conclusion clients.

At Flexagon, we’ve been assisting IT groups integrate DevOps practices and outfit into their existing strategies for years – and hold abysmal potential in Oracle know-how, including E-enterprise Suite. We’ve combined their journey with E-enterprise Suite with widely wide-spread DevOps and progress most excellent practices to create a list of 10 edifice assistance for Oracle EBS.

These counsel will aid developers standardize their tactics, store time, and carve back errors during construction, testing, and deployment to production. They might too even accomplish a contribution to your efforts to truncate the utility beginning lifecycle and should extol continuous methodologies like continual integration and continuous birth.

most fulfilling Practices for E-company Suite development1. Standardize Naming Conventions

Don’t fritter time naming database objects in response to dispassionate conventions, then the employ of ad hoc naming for file gadget objects. as a substitute, approach up with naming conventions that can subsist easily replicated in scripts, executables, reports, kinds and extra. via taking this approach from the beginning, any out-of-context coding, as an instance in a JIRA ticket, can too subsist readily understood.

2. song AOL changes to your SCM

building groups most commonly implement AOL adjustments in a shared EBS progress atmosphere. for the intuition that EBS does not preserve song of revisions of alterations, it is premiere drill to extract every AOL change to an .LDT and checklist the revision as a consign into your source control equipment.

that you would subsist able to employ DevOps tooling to automate the migration of the AOL adjustments the employ of the FNDLOAD program. as with every file, you could hold visibility into which revisions of your AOLs the plot deployed, when, where, and by using whom.

3. Simplify Server administration and in the reduction of complications with Automation

Oracle E-enterprise Suite consists of a variety of servers, features, and workflows. each and every of those components requires diverse handling to cease, start, restart, permit, or disable. Managing these diverse server components isn't a straightforward project. Automating server management is essential for creation environments for right here purposes:

  • choosing which server/element to birth in its plot of beginning/stopping/restarting the entire servers
  • cutting back downtime by pass of replacing usher tactics with automation
  • Combining with deployment operations to accomplish inescapable deployed alterations retreat into impact
  • including approvals and/or notifications to boost control and visibility
  • 4. enrich Versioning for outfit Migration

    alas, it’s ordinary for IT teams emigrate packages, then determine that they aren’t working with the newest version of the code. no longer handiest is that irritating, however too wastes time and extends your software beginning lifecycle.

    instead of struggling to establish which edition of the code you’re working with, accomplish reviewing kit versions less demanding with the aid of including a version code right after the header revision comments in your PL/SQL package. This may too subsist completed manually via the team or by using DevOps equipment and continuous strategies to accomplish inescapable here is accomplished every time code is migrated.

    5. structure Your Code

    All coding – no longer handiest packages being readied for migrations – may noiseless observe ordinary protocols. The train right here is to accomplish the software’s code as simple and readable as possible. employ the case office or indent code invariably to accomplish code fragments convenient and predictable to read.

    whatever code structure you employ, preserve it constant totality over your company. everybody may noiseless subsist in a position to with no danger view and understand code the usage of the identical system.

    6. subsist awake of When to employ Patch vs. hurry edition

    Oracle E-business 12.2 and above comes with versions (Run and Patch). which you could set up your customizations without retard to hurry edition or apply to Patch version (online Patching) with the aid of following ADOP patching phases. on-line Patching cycle consists of the following principal phases:

  • prepare
  • follow
  • Finalize
  • Cutover
  • Cleanup
  • online patching reduces downtime and is too known as 0 downtime deployment.

    you could set up adjustments without retard into the hurry edition. This alternative should subsist used when alterations are minuscule or when the modern on-line patching alternate options aren't adopted.

    7. Create Reusable Frameworks

    Your IT team doesn’t necessity to spend time getting to know modern construction frameworks and specifications until there’s a particular need. So, as you create frameworks to develop your latest Oracle functions, subsist confident they can too subsist replicated in future implementations.

    for example, you could enhance a common set of 20 inventory categories that ensue a group of naming conventions that can subsist used across tasks. employ these frameworks throughout teams and with your entire Oracle EBS progress tools to create in-apartment necessities that keep time.

    eight. reduce manual, Repeatable projects with Idempotent Database Scripts

    EBS implementations are composed of colossal volumes of database objects and PL/SQL programs. fancy several EBS object, these definitions necessity to subsist synchronized across many environments in your topology. frequently, these objects are migrated across environments with the aid of the DBA by executing DDL/SQL scripts offered by using the construction team.

    one of the greatest challenges in automating the system is managing updates to existing Oracle database objects. here's relatively fundamental for objects which hold CREATE OR substitute objects, however that isn't the case for a lot of of the article varieties (e.g. tables, indexes, sequences, and many others.). as an example, you can not execute a create desk statement if the desk already exists. here is most frequently managed by pass of writing scripts which are elegant on the situation of the object in the goal atmosphere. When it involves automating the manner, this becomes a challenge.

    One technique is to create totality DDL/SQL scripts to subsist idempotent, yielding the identical outcomes even when applied a number of times. in case you observe this observe, that you can maintain a lone script it really is used to ensue alterations throughout totality environments, tune the revision of the script throughout environments, and foster healthier relationships between developers and DBAs.

    There are distinctive recommendations used, which vary by object classification. In most cases, youngsters, the scripts necessity to investigate the present situation and undertake its conduct. For staging tables or stateless objects, effectively shedding and re-developing the object is the most advantageous formula (taking freight not to fail if the detail does not exist). For stateful objects, akin to permanent tables and sequences, you must deal with insert/replace circumstances, totality whereas maintaining any state.

    9. steer transparent of challenging Coding

    challenging code or configure? The option appears glaring, however it bears repeating: always configure to obviate problems and further toil down the highway.

    In times in case you believe inclined to allocate values to your code – either strings or numeric – regard where else you can tangle this records. If it’s not accessible elsewhere, it's most effectual to hold the time to strengthen custom profile options, descriptive flex fields (DFF) or key flex fields to extra with no danger itemize categories.

    10. Automate and neighborhood initiatives together

    Most companies hold a couple of environments for numerous purposes fancy building, device checking out, performance trying out, creation, etc. For successful delivery of features to construction, it's essential that progress groups adopt automation practices.

    Automation can too subsist employed to conclude a variety of mundane tasks fancy configuration and code deployment, excellent testing, and more. Automation should noiseless champion linger away from errors and drive consistency, which means a discount in downtime and outages. In instances the plot projects deserve to subsist performed totality over late nighttime or weekend hours, automation and scheduling can additionally waiton help work-lifestyles steadiness.

    As corporations undertake automation, it is a amenable belief to provide tools for visibility into computerized changes to diagnose problems or for audit tracking for a variety of compliance methods. tools that accomplish it handy to group changes together for merchandising can too also waiton you control your EBS application start lifecycle that spans anyplace from just a few days to weeks or months.

    Use specifications and Automation to enhance Oracle E-company Suite App building

    Oracle products are extremely really good, and IT groups engaged on them typically boost their personal in-condominium processes in accordance with instructions from Oracle and adventure with E-company Suite. Framing that into requirements and automating processes to carve back guide, repeatable projects and reduce down on errors can vastly help app construction.

    To complement your in-apartment tactics and most trustworthy practices, which you can additionally believe adding DevOps outfit with software unencumber automation and other functionality to your IT toolset. These outfit will additional alleviate the cross of usher toil in your crew, helping streamline processes and mainstreaming the optimal practices which are already on your tactics.

    Netflix Billing Migration to AWS — participate III | real questions and Pass4sure dumps

    In the billing migration blog post published a few weeks ago, they explained the overall approach employed in migrating their billing system to the cloud:

    In this post, the database migration portion will subsist covered in detail. They hope that their experiences will waiton you as you undertake your own migrations.

    Have you ever wondered about the elements that necessity to approach together and align to tangle a complicated database migration right? You might ask, “What makes it complicated?”

    Think of any challenge in database migration and pretty much totality of them were there in this migration:

  • Different hardware between source and target
  • OS flavours
  • Migration across heterogeneous databases
  • Multiple datacenters — Netflix data headquarters (DC) and AWS cloud
  • Criticality of the transactional billing data
  • Selective dataset migration
  • Migration of constantly changing data, with minimal downtime
  • Billing, as most of you would agree, is the faultfinding service for any company. The database is the most essential factor in any migration and getting it right determines the success or failure of the all project. The Netflix CDE (Cloud Database Engineering) team was tasked with migrating this faultfinding subsystem database. The following sections portray some of key areas they focused on in order to ensure a successful migration.

    Choice of the database

    Billing applications hold transactions that necessity ACID compliance to process the payment for charged transactions. RDBMS seemed the right selection for the datastore.

    Oracle: As source database was in Oracle, migrating to Oracle in Cloud would avoid cross database migration, simplifying the coding trouble and configuration setup. Their sustain with Oracle in production gave more confidence with respect to its performance and scalability. However, considering the licensing costs and the technical debt required to migrate legacy data “as is”, prompted us to explore other options.

    AWS RDS MySQL: Ideally they would hold gone with MySQL RDS as their backend, considering Amazon does a noteworthy job in managing and upgrading relational database as a service, providing multi-AZ champion for high availability. However, the main drawback to RDS was the storage limit of 6TB. Their requirement at the time, was closer to 10TB.

    AWS Aurora: AWS Aurora would hold met the storage needs, but it was in beta at that time.

    PostgreSQL: PostgreSQL is a powerful open source, object-relational database system, but they did not hold much in house expertise using PostgreSQL. In the DC, their primary backend databases were Oracle and MySQL. Moreover, choosing PostgreSQL would hold eliminated the option of a seamless migration to Aurora in future, as Aurora is based on the MySQL engine.

    EC2 MySQL: EC2 MySQL was ultimately the selection for the billing employ case, since there were no licensing cost and it too provided a path to future Aurora migration. This involved setting up MySQL using the InnoDB engine on i2.8xlarge instances.

    Production Database Architecture

    High availability and scalability were the main drivers in designing the architecture to waiton the billing application withstand infrastructure failures, zone and region outages, and to conclude so with minimal downtime.

    Using an DRBD copy in another zone for the primary master DB, helped withstand zone outages, infrastructure failures fancy noxious nodes, and EBS volume failures. “Synchronous replication protocol” was used to enable the write operations on the primary node to subsist considered completed, only after both the local and remote writes hold been confirmed. As a result, the loss of a lone node is guaranteed to hold no data loss. This would impact the write latency, but that was well within the SLAs.

    Read replica setup in local, as well as cross region, not only met high availability requirements, but too helped with scalability. The read traffic from ETL jobs was diverted to the read replica, frugal the primary database from heavy ETL batch processing.

    In case of the primary MySQL database failure, a failover is performed to the DRBD secondary node that was being replicated in synchronous mode. Once secondary node takes over the primary role, the route53 DNS entry for database host is changed to point to the modern primary. The billing application being batch in nature is designed to manipulate such downtime scenarios. The client connection conclude not fallback but establish modern connections that would point to the modern primary after the Cname propagation is complete.

    Choice of Migration Tool

    We spent considerable time and trouble in choosing the right appliance for the migration. Primary success criteria for the POC was the ability to restart bulk loads, bi-directional replication, and data integrity. They focused on the following criteria while evaluating a appliance for the migration.

  • Restart bulk/incremental loads
  • Bi-directional replication
  • Parallelism per table
  • Data integrity
  • Error reporting during transfer
  • Ability to rollback after going live
  • Performance
  • Ease of use
  • GoldenGate stood out in terms of features it offered which aligned very well with their employ case. It offered the ability to restart bulk loads in case of failures (a few tables were hundreds of GB in size), and its bi-directional replication feature provided effortless rollback from MySQL to Oracle.

    The main drawback with GoldenGate was the learning curve in understanding how the appliance works. In addition, its manual configuration setup is recumbent to human error, which added a layer of difficulty. If there is no primary key or unique key on the source table, GoldenGate uses totality columns as the supplemental logging key pair for both extracts and replicats. They organize issues fancy duplicate data at the target in incremental loads for such tables and decided to execute a replete load during the cutover for those specific tables with no pre-defined primary or unique key. The advantages and features offered by GoldenGate far exceeded any challenges and was the appliance of choice.

    Schema Conversion and Validation

    Since source and target databases were different, with data nature and data length differences, validation became a crucial step in getting the data migrated while keeping the data integrity intact.

    Data nature mismatch took sometime to fix the issues stemming from it. One example — many numeric values in Oracle were defined as the Number datatype for legacy reasons. There is no equivalent nature in MySQL. The Number datatype in Oracle stores fixed and floating-point numbers which was tricky. Some source tables had columns where Number meant an integer, in other cases it was used for decimal values, while some had really long values up to 38 digits. In contrast, MySQL has specific datatypes fancy Int, bigInt, decimal, double etc and a bigInt cannot retreat beyond 18 digits. One should ensure that revise mapping is done to reflect the accurate values in MySQL.

    Partitioned tables needed special handling, since unlike Oracle, MySQL expects the partition key to subsist the participate of the primary key and unique key. Target schema had to subsist redefined with proper partitioning keys to ensure no negative impact on application logic and queries.

    Default value handling too differs between MySQL and Oracle. For the columns with a NOT NULL value, MySQL determined the implicit default value for the column. Strict mode had to subsist enabled in MySQL to tangle such data conversion issues, as such transactions would fail and exhibit up in the GoldenGate oversight logs.

    Tools for schema conversion: They researched a variety of tools to assist in schema conversion as well as validation, but the default schema conversion provided by these tools did not toil due to their legacy schema design. Even GoldenGate does not transmogrify Oracle schema to the equivalent MySQL version, but instead depends on the application owners to define the schema first. Since one of their goals with this migration was to optimize schema, the database and application teams worked together to review the data types, and did multiple iterations to capture any mismatch. GoldenGate will truncate the value to apt the MySQL datatype in case of a mis-match. They relied heavily on data comparison tools and the GoldenGate oversight logs to waiton detect mismatches in data nature mapping between source and target, in order to mitigate this issue.

    Data Integrity

    Once the replete load completed and incrementals caught up, another daunting chore was to accomplish confident the target copy correctly maintained the data integrity. As the data types between Oracle and MySQL were different, it was not workable to hold a generic wrapper script to compare hash values for the rowkeys to ensure accuracy. There are a few 3rd party tools which conclude the data comparisons across databases comparing the actual values, but the total dataset is 10 TB which was not effortless to compare. Instead, they used these tools to match a sample data set which helped in identifying a few discrepancies related to wrong schema mapping.

    Test refreshes: One of the ways to ensure data integrity was to conclude the application testing on a copy of the production database. This was accomplished by scheduling database refreshes from the MySQL production database to test. Considering production was being backed by EBS for storage, a test environment was easily created by taking the EBS snapshots off the slave, and doing a point in time recovery into test. This process was repeated several times to ensure data quality.

    Sqoop jobs: ETL jobs and reporting were used to waiton with data reconciliation process. Sqoop jobs pulled data out of Oracle for reporting purposes. Those jobs were too configured to hurry against MySQL. With continuous replication between source and target, reports were hurry against specific time window on the ETLs. This helped in taking out the variation due to incremental loads.

    Row counts was another technique used to compare the source/target and match them. This was achieved by pausing the incremental loads on the target and matching the counts on Oracle and MySQL. Results from row counts were too compared after replete GoldenGate load of the tables.

    Performance Tuning

    Infrastructure: Billing application persisted data in the DC on two Oracle databases residing on very powerful machines, using IBM power 7, 32 dual core 64 bit multiprocessors, 750GB RAM, TB’s storage allocated via SVC MCS cluster which is 8G4 cluster with 4GB/sec interface running with RAID 10 configurations.

    One major concern with the migration was performance, as the target database was consolidated on one i2.8xlarge server, using 32 vCPU and 244 GB RAM. The application team did a lot of tuning at the application layer to optimize the queries. With the waiton of Vector the performance team was able to find bottlenecks and eradicate them by tuning specific system and kernel parameters. espy Appendix for more details.

    High performance with respect to reads and writes was achieved by using RAID0 with EBS provisioned IOPS volumes. To tangle more throughput per volume, 5 volumes of 4TB each were used, instead of 1 substantial volume. This was to facilitate faster snapshots and restores.

    Database: One major concern using MySQL was the scale of their data and MySQL throughput during batch processing of data by billing applications. Percona provided consulting support, and the MySQL database was tuned to effect well during and after the migration. The main trick is to hold two cnf files, one while migrating the data and tweaking parameters fancy innodb_log_file_size to waiton with bulk inserts, and the second cnf file for the real time production application load by tweaking parameters fancy innodb_buffer_pool_instances to waiton with the transaction real time load. espy Appendix for more details.

    Data load: During POC, they tested the initial table load with indexes in on/off combination and decided to retreat with enabling totality indexes before the load. The reasoning behind this was that index creation in MySQL is lone threaded (most tables had multiple indexes), and so they instead utilized Golden Gate’s parallel load feature to populate the table with indexes in reasonable time. strange key constraints were enabled during the final cutover.

    Another trick they scholarly was to match the total number of processes executing replete and incremental load, to the number of cores on the instance. If the processes exceeded the number of cores, the performance of those data loads slowed down drastically as the instance would spend a lot of time in context switches. It took around 2 weeks to populate 10 TB in target MySQL database with the replete loads and hold incremental loads tangle up.


    Though the database piece is one of the most challenging aspects of any migration, what really makes a unlikeness between success and failure is ensuring you are investing in the right approach up front, and partnering closely with the application team throughout the process. Looking back on the all migration, it was truly a commendable trouble by different teams across the organization, who came together to define the all migration and accomplish the migration a noteworthy success! Along with the individual and cross team coordination, it’s too the noteworthy culture of freedom and responsibility which makes these challenging migrations workable without impacting business.

    SQL Monitoring and ASH Analytics in Oracle Enterprise Manager: real questions with Edward Whalen | real questions and Pass4sure dumps

    Sep 20, 2013

    Edward Whalen, an Oracle ACE and the Chief Technologist at Performance Tuning Corporation (, was recently featured in an Oracle Enterprise Manager SIG webinar about Oracle Enterprise Manager 12c. Here, he shares his thoughts about the significance of the features provided in the latest release of Enterprise Manager and why they are faultfinding to Oracle users.

    Why are you interested in Enterprise Manager 12c?EW: Oracle Enterprise Manager Cloud Control is the latest and greatest Enterprise Manager product from Oracle. In terms of lifecycle management, in terms of managing the database, and in terms of just managing the all enterprise, it has got some noteworthy features.

    In the webcast, I focused on the performance management tools within the Oracle Database, which are ASH Analytics and SQL Monitoring. The intuition I was asked to participate is that Oracle Press actually just published a engage that I wrote on this topic with my colleagues, Michael New and Matthew Burke, titled, “Oracle Enterprise Manager Cloud Control 12c abysmal Dive.”

    Do you employ Enterprise Manager?

    EW: I employ this technology totality the time. I am a database consultant and I mainly focus on performance problems as well as implementations and data migrations, so I employ technologies such as Oracle GoldenGate, Data Guard, and Oracle RAC. Oracle Enterprise Manager Cloud Control 12c really provides a lot of capabilities for managing these features of Oracle and gives you the ability to not only manage but monitor and set up alerting. I implement, configure and manage Oracle Enterprise Manager 12c for a number of customers. I treasure Oracle Enterprise Manager 12c. I am a huge fan of the product.

    Do your customers find it helpful?

    EW: It is extremely useful. The database administrator’s main chore in life is to keep the database up and running. So being able to set up proactive alerts and proactive monitoring and pinpoint when something is happening before the user community is calling to complain about it, is really essential to DBAs in order to provide a really noteworthy even of service for their customers and quit users.

    How did Oracle Enterprise Manager 12c evolve as a product?

    EW: The 12c version of Oracle Enterprise Manager actually came out a replete year before the 12c version of the database. The version 12c of Enterprise Manager doesn’t require the 12c version of the database and, in fact, 12c can manage and monitor not only 12c databases but 11g databases, 10g, 9i, and so forth. Prior to Oracle Enterprise Manager Cloud Control, the product was called Oracle Grid Control. Version 10 and version 11 of Oracle Grid Control hold been out there for awhile and then with version 12c, Oracle named it Cloud Control.

    The modern feature for performance monitoring and performance tuning is a feature only available in Oracle Enterprise Manager called ASH Analytics.  ASH stands for active Session History so ASH Analytics is what I covered in the webinar – showing how it allows you to dig into what is actually happening in your system on a per-session even even to the point of allowing you to seclude which session and which SQL statement is using the most I/O, or has the greatest CPU utilization, or which ones are holding the most locks.  I am able to dig into those details with the ASH Analytics appliance and that is a modern feature that was not available in the earlier versions of Grid Control.

    How long hold you been a member of the IOUG?

    EW: More than 15 years.

    What has your sustain been?

    EW: I treasure the IOUG. I especially fancy the IOUG presentations at COLLABORATE because they provide more of the actual down and nasty database administration – really technical information. If you want to learn something about Oracle products and learn about how the DBAs toil and what benevolent of things they hurry into, you mind to find more about that at COLLABORATE.

    What is it that you will subsist looking for more information on at Oracle OpenWorld this year?

    EW: I am mainly looking forward to getting more information about the modern features in Oracle 12c Database. I too toil quite a lot with Oracle GoldenGate and I know they are making a lot of improvements there, so I am planning on attending a few of those sessions as well.

    DevOps for Oracle Apps: 10 E-Business Suite progress Tips | real questions and Pass4sure dumps

    The most effectual progress processes are tailored to the company and product IT teams are working with. The most effectual teams develop standardized processes that waiton reduce errors and hurry up the software delivery lifecycle while increasing efficiency for their specific product.

    DevOps spans people, process, and technology, and can subsist integrated into every IT team. Combined with best practices for each team’s technical landscape, it can create more efficient processes that deliver high-quality software to market in less time.

    That’s especially suitable for IT teams working on Oracle apps such as E-Business Suite. Combining DevOps practices with specific progress tips for E-Business Suite will accomplish entire teams more effectual and bear greater results for quit users.

    At Flexagon, we’ve been helping IT teams integrate DevOps practices and tools into their current processes for years – and hold abysmal expertise in Oracle technology, including E-Business Suite. We’ve combined their sustain with E-Business Suite with common DevOps and progress best practices to create a list of 10 progress tips for Oracle EBS.

    These tips will waiton developers standardize their processes, redeem time, and reduce errors throughout development, testing, and deployment to production. They may even contribute to your efforts to truncate the software delivery lifecycle and will compliment continuous methodologies like continuous integration and continuous delivery.

    Best Practices for E-Business Suite Development 1. Standardize Naming Conventions

    Don’t fritter time naming database objects based on measure conventions, then using ad hoc naming for file system objects. Instead, approach up with naming conventions that can subsist easily replicated in scripts, executables, reports, forms and more. By taking this approach from the beginning, any out-of-context coding, for sample in a JIRA ticket, can subsist easily understood.

    2. Track AOL Changes in Your SCM

    Development teams most often implement AOL changes in a shared EBS progress environment. Since EBS does not keep track of revisions of changes, it is best drill to extract each AOL change to an .LDT and record the revision as a consign into your source control system.

    You can employ DevOps tooling to automate the migration of the AOL changes using the FNDLOAD program. As with any file, you will hold visibility into which revisions of your AOLs where deployed, when, where, and by whom.

    3. Simplify Server Management and Reduce Problems with Automation

    Oracle E-Business Suite consists of many different servers, services, and workflows. Each of these components requires different handling to stop, start, restart, enable, or disable. Managing these different server components is not an effortless task. Automating server management is faultfinding for production environments for the following purposes:

  • Determining which server/component to start instead of starting/stopping/restarting totality the servers
  • Reducing downtime by replacing manual processes with automation
  • Combining with deployment operations to ensure deployed changes retreat into effect
  • Adding approvals and/or notifications to extend control and visibility
  • 4. help Versioning for Package Migration

    Unfortunately, it’s common for IT teams to migrate packages, then find out that they aren’t working with the latest version of the code. Not only is that frustrating, but it too wastes time and extends your software delivery lifecycle.

    Instead of struggling to identify which version of the code you’re working with, accomplish reviewing package versions easier by adding a version code right after the header revision comments in your PL/SQL package. This can subsist done manually by the team or by using DevOps tools and continuous processes to ensure this is done each time code is migrated.

    5. Structure Your Code

    All coding – not only packages being readied for migrations – should ensue measure protocols. The train here is to accomplish the application’s code as simple and readable as possible. employ the case office or indent code consistently to accomplish code fragments effortless and predictable to read.

    Whatever code structure you use, keep it consistent throughout your organization. Everyone should subsist able to easily view and understand code using the identical system.

    6. Know When to employ Patch vs. hurry Edition

    Oracle E-Business 12.2 and above comes with editions (Run and Patch). You can deploy your customizations directly to hurry Edition or apply to Patch Edition (Online Patching) by following ADOP patching phases. Online Patching cycle consists of the following major phases:

  • Prepare
  • Apply
  • Finalize
  • Cutover
  • Cleanup
  • Online patching reduces downtime and is too called 0 downtime deployment.

    You can deploy changes directly into the hurry edition. This option should subsist used when changes are minuscule or when the modern online patching options are not adopted.

    7. Create Reusable Frameworks

    Your IT team doesn’t necessity to spend time learning modern progress frameworks and standards unless there’s a specific need. So, as you create frameworks to develop your current Oracle applications, subsist confident they can subsist replicated in future implementations.

    For example, you can develop a measure set of 20 inventory categories that ensue a set of naming conventions that can subsist used across projects. employ these frameworks across teams and with totality your Oracle EBS progress tools to create in-house standards that redeem time.

    8. Reduce Manual, Repeatable Tasks with Idempotent Database Scripts

    EBS implementations are composed of big volumes of database objects and PL/SQL programs. fancy any EBS object, these definitions must subsist synchronized across many environments in your topology. Often, these objects are migrated across environments by the DBA by executing DDL/SQL scripts provided by the progress team.

    One of the biggest challenges in automating the process is managing updates to existing Oracle database objects. This is pretty simple for objects which hold CREATE OR supersede objects, but that is not the case for many of the object types (e.g. tables, indexes, sequences, etc.). For example, you cannot execute a create table statement if the table already exists. This is most often managed by writing scripts that are dependent on the situation of the object in the target environment. When it comes to automating the process, this becomes a challenge.

    One technique is to create totality DDL/SQL scripts to subsist idempotent, yielding the identical result even when applied several times. If you ensue this practice, you can maintain a lone script that is used to apply changes across totality environments, track the revision of the script across environments, and foster healthier relationships between developers and DBAs.

    There are different techniques used, which vary by object type. In most cases, however, the scripts must check the current situation and adopt its behavior. For staging tables or stateless objects, simply dropping and re-creating the object is the best fashion (taking freight not to fail if the object does not exist). For stateful objects, such as permanent tables and sequences, you must manipulate insert/update conditions, totality while preserving any state.

    9. Avoid hard Coding

    Hard code or configure? The selection seems obvious, but it bears repeating: always configure to avoid complications and additional toil down the road.

    In times when you feel inclined to allocate values to your code – either strings or numeric – regard where else you can tangle this data. If it’s not available elsewhere, it is best to hold the time to develop custom profile options, descriptive flex fields (DFF) or key flex fields to more effectively itemize categories.

    10. Automate and Group Tasks Together

    Most organizations hold a few environments for various purposes fancy development, system testing, performance testing, production, etc. For successful delivery of features to production, it is essential that progress teams adopt automation practices.

    Automation can subsist employed to conclude various mundane tasks fancy configuration and code deployment, character testing, and more. Automation should waiton avoid errors and oblige consistency, which means a reduction in downtime and outages. In cases where tasks necessity to subsist done during late night or weekend hours, automation and scheduling can too waiton help work-life balance.

    As organizations adopt automation, it is a amenable belief to provide tools for visibility into automated changes to diagnose problems or for audit tracking for various compliance processes. Tools that accomplish it effortless to group changes together for promotion may too waiton you manage your EBS software delivery lifecycle that spans anywhere from a few days to weeks or months.

    Use Standards and Automation to help Oracle E-Business Suite App Development

    Oracle products are highly specialized, and IT teams working on them typically develop their own in-house processes based on guidelines from Oracle and sustain with E-Business Suite. Framing that into standards and automating processes to reduce manual, repeatable tasks and carve down on errors can greatly help app development.

    To supplement your in-house processes and best practices, you can too regard adding DevOps tools with application release automation and other functionality to your IT toolset. These tools will further alleviate the cross of manual toil on your team, helping streamline processes and mainstreaming the best practices that are already in your processes.
