there were quite a few releases by using Oracle RDBMS starting from Oracle v2 (there changed into no Oracle v1, as they assumed nobody may additionally are looking to purchase a edition 1), to the latest Oracle database 11g and then Oracle Database 12c. With each and every free up of the Oracle database, there had total the time been an help path that necessary to breathe adopted with the aid of the clients.
there are lots of who are overconfident and blindly rush in as quickly as a brand unusual unencumber comes out. They are attempting to down load or upgrade even earlier than realizing what exactly they deserve to do. besides the fact that children, this can also, many of the time, occasions catastrophe, which might breathe plenty ascetic when it comes to a enterprise or business environment. prerogative through 2016, they noticed both newest Oracle Database types:
Oracle Database 12c - business edition: As Oracle’s flagship database suite, EE is a full-featured version of Oracle RDBMS with the option to obtain add-on features like database options and administration packs with complete exploration of the server supplies.
Oracle Database 12c - common version 2: here's a lighter edition meant for small and medium measurement implementations. SE2 comes with a restrained set of DB aspects however with access to precise utility Clusters. Oracle introduces SE2 as a starter version, with handy upward compatibility to the better version.Upgrading to Oracle Database 12c
for those who are the usage of older types of Oracle databases, the upgrade direction to Oracle Database 12c is straightforward. youngsters, if you're the usage of a version that does not cheer an instantaneous upgrade, then you definately ought to first upgrade it to a supported version and additional to Oracle Database 12c. As of late, the direct upgrade is supported from:
Oracle Database 10g
Oracle Database 11g
There are three alternatives for upgrading:
in this article, they are able to heart of attention extra on the route to consume the Database upgrade Assistant, which is a established routine for upgrading.Database help Assistant
Oracle has currently enhanced the DBUA by means of ensuring alternatives for a seamless upgrade. The clients now possess the preference to repair any error without delay from the DBUA, and moreover, it makes monitoring the upgrade tons less difficult and in actual-time. as a route to consume DBUA, clients deserve to entry the domestic page of Oracle Database 12c and start by means of running the DBUA. The ultimate ensue is to evade the preupgrd.sql to peer what can too ought to repair before operating the assistant.working PREUPGRD.SQL
For running ‘preupgrd.sql’, one first must deploy unusual binaries into Oracle DBA home. once that is executed, set up the atmosphere to join it to the database obligatory to breathe upgraded.
As a sample, they can grasp the instantly previous Oracle Database 11g settings:ORACLE_SID=ora 11g ORACLE_BASE=/decide/oracle ORACLE_HOME=/choose/oracle/product/11.2.0.three.0/db_1
Then entry the directory wherein the preupgrd.sql file is obtainable.#>cd/decide/oracle/product/188.8.131.52/dbhome_1/rdbms/admin
After this, they ought to connect the 11g database with SQL*Plus to evade preupgrd.sql#>sqlplus / as sysdba SQL>@preup grd.sql
After running the script, they will obtain the file places, which can breathe obligatory for reference to examine and correct any considerations with the ambiance later.
The consequences of this examine may breathe observed at:/decide/oracle/cfgtoollogs/ora11/preup grade/preup grade.log
The pre-upgrade repair-up script evade at the source database atmosphere is:/choose/oracle/cfgtoollogs/ora11/preup grade/preup grade_fixups.sql
The submit-upgrade repair-up script evade after the help is:/opt/oracle/cfgtoollogs/ora11/preup grade/postup grade_fixups.sql
as soon as reached as much as this stage, which you can evaluate these scripts to correct if anything requires extra fixes. once these fixes are done properly, working DBUA will develop into an poor lot more straightforward. The mistakes listed in preupgrade.log too obligatory to breathe corrected earlier than running DBUA.operating DBUA
as soon as preupgrade.log is reviewed and corrected, next you possibly can birth with Database upgrade Assistant.
log on to Oracle Database 12c domestic after which evade the DBUA:#> cd/choose/oracle/product/184.108.40.206/dbhome_1/bin #> ./dbua&
working this will initiate the GUI to birth instantly and obtain upgraded. There is not any deserve to trade anything within the atmosphere, which could nevertheless breathe the 11g installation.ORACLE_SID=ora11g ORACLE_BASE=/choose/oracle ORACLE_HOME=/choose/oracle/product/11.2.0.three.0/db_1
once the DBUA starts, just ensue the steps below.Step 1
improve Oracle database > circulation the latest 12c database to domestic of 12c Oracle > select improve, click next.Step 2
We should establish which Oracle home needs to breathe upgraded. As we've it set to 11g domestic, during this case, the DBUA will disclose total databases associated with the 11g Oracle home. opt for which database needs to breathe upgraded and click subsequent.Step three
The effects may well breathe similar to what they noticed at preupgrade.log. The DBUA is too working the selfsame preupgrd.sql script and should recrudesce with the results. however, the aide is made to breathe extra shrewd with the capacity to permit users to pick whether the considerations to breathe fastened, overlooked, or revalidated.Step four
Oracle has made a captivating exchange here as the help can breathe achieved in parallel. here is made feasible with the aid of shrewd Perl script called catctl.pl. they can additionally recompile objects in parallel and let the DBUA acquire statistics, operate upgrades, and design the tablespaces examine-simplest as the upgrade runs.Step 5
This step will enable clients to control the Oracle Database 12c environment. you could consume EM specific or can register the DB with OEM 12c (Oracle commercial enterprise supervisor). The DBUA will instantly pick on the necessary advice if OEM12c brokers are already installed on the server.Step 6
clients can specify the situation the data data deserve to breathe moved and install the speedy healing region (FRA). which you can additionally configure the Oracle Managed files (OMF).Step 7
This step is designed to cheer users to migrate the 11g listener to 12c. The ‘migrate’ column on the disclose at this step is terribly critical. here is what tells you even if the listener is going to breathe migrated.Step 8
Now, clients possess the option to create a backup of the database before the upgrade runs. that you would breathe able to additionally school the DBUA by means of determining a radio button now not to execute a backup if you're confident about your current backup practices.Step 9
we've reached the abstract screen, which will disclose what the DBUA plans to do. review this screen carefully to design unavoidable that every miniature thing is so as earlier than clicking the ‘conclude’ button to birth the upgrading method. once clicked, the upgrade will delivery and they will survey that popularity on the growth screen.
once the help is completed, the cease button on the window will alternate to ‘improve outcomes.’ click on on this and you may survey the interface altering to deliver the outcomes of the latest upgrade. The easiest route to examine the upgrade is to examine ‘and so forth/oratab’ file. If the help is correctly achieved, then this oratab file may too possess changed the Oracle domestic in sync with the 12c binary place.
i am hoping this text provided you with the least difficult and most consumer-pleasant route of upgrading Oracle from the outdated 11g edition to the newest Oracle Database 12c edition.

Learn how virtualization management tools Oracle Enterprise Manager Ops heart and OpenStack can facilitate the process of automating virtualization.This chapter is from the reserve
Early computers were expensive, prompting their owners to squeeze total viable value out of them. This drive led to the introduction of time-share operating systems, on which many workloads may evade at the selfsame time. As per-unit cost dropped, single-user, single-workload operating systems became popular, but their adoption created the mindset of “one workload per computer,” even on servers. The result was an explosion of under-utilized servers. The high costs of maintaining so many servers led to the widespread embrace of virtualization, with the goal of reducing the quantity of servers owned by organizations. Consolidation via virtualization may possess reduced a company’s hardware acquisition costs, but it did nothing to help the organization’s maintenance costs. Ultimately, managing VEs one at a time is no easier than managing one server at a time.
Many virtualization management tools exist on the market that can facilitate the process of automating virtualization. This chapter discusses two of them: Oracle Enterprise Manager Ops heart and OpenStack.
Oracle Enterprise Manager Ops heart 12c is partake of the broader Oracle Enterprise Manager product. Whereas Enterprise Manager Cloud Control focuses on the higher halt of the stack (i.e., database, middleware, and applications), Ops heart addresses the lower halt (i.e., storage, operating systems, hardware, and virtualization).
Ops heart is designed for complete life-cycle management of the infrastructure layer, which includes both Oracle hardware and operating systems. From a hardware perspective, it is capable of functions such as the following:
Discovery of unusual and existing hardware
Upgrading server firmware
Installing the “bare metal” operating system
Monitoring hardware components and opening service requests automatically if a hardware weakness occurs
Providing console access to the system
Other management actions such as power-off/on, set locator lights, and others
Paramount in Ops Center’s functionality portfolio is managing the two primary virtualization technologies: Oracle Solaris Zones and Kernel Zones, and Oracle VM Server for SPARC. Provisioning virtual environments (VEs) including those types includes performing any required preparation of the hardware and operating system.7.1.1 Architecture
The architecture of Ops heart consists of three main sections:
Enterprise Controller: The main server component of Ops Center. The enterprise controller delivers the user interface and stores the enterprise-wide configuration information. An organization that uses Ops heart will possess at least one enterprise controller system that provides communication back to Oracle for service requests, automated patch and firmware downloads, contract validation, and other activities. However, many catastrophe recovery sites include their own enterprise controller so that they can continue operations management, if needed, during service outages that move the repose of the system.
Proxy Controller: The component that communicates to the managed assets, including hardware assets, operating system assets, storage assets, virtualized assets, and others. If total of the systems being managed by Ops heart are in one data center, only one proxy controller is needed, and it can evade in the selfsame server as the enterprise controller. Alternatively, you can install multiple proxy controllers per enterprise controller. gauge configurations consume one or more proxy controllers per data center, to expand the compass of the Ops heart environment to other data centers, networks, or DMZs.
Agent: A proxy controller typically manages deployed software components via a software agent installed on the system. When an agent is not appropriate, an operating system can breathe managed without one. The Ops heart agent supports Solaris 8, 9, 10, and 11.
Figure 7.1 depicts the Ops heart architecture.7.1.2 Virtualization Controllers
The Ops heart administrator can pick from two types of virtual environments. One character uses Solaris Zones; this character is simply called a global zone. The other character is a control domain, whose cognomen refers to the consume of OVM Server for SPARC. total systems that can breathe managed by Ops heart can breathe the global zone type. On modern SPARC systems, you can pick either a control domain or a global zone.
After you design that choice, Ops heart deploys the confiscate character of agent software in the management space, either the computer’s control domain or global zone. This agent is called the virtualization controller (VC). Once its installation is complete, you can create the confiscate character of VEs on that server: ratiocinative domains for a control domain, or Solaris Zones for a global zone.7.1.3 Control Domains
Control domains (CDoms) manage Oracle VM Server for SPARC ratiocinative domains (LDoms) on a computer. When you consume Ops heart to provision a CDom, you pick the operating system, CDom hardware configuration (RAM, cores, and I/O), and names of virtual services provided to other domains. The service names include those for virtual disk services, network services, and console services. You can too initialize advanced Solaris features at the network layer for improved redundancy and performance, such as link aggregation. Advanced configurations, such as SR-IOV, service domains, and root complicated domains, are too supported.
Once the CDom is provisioned, the Ops heart user can open structure guests. The guests must boot from either a virtual or physical disk. Using virtual disks provides the greatest flexibility at an extremely minimal performance cost. Virtual disks can reside on a number of physical media available to the CDom:
A local file system
A local disk
An iSCSI LUN
A NAS file system
A FibreChannel LUN
When creating LDom guests, the Ops heart user creates one or more ratiocinative domain profiles that define the make-up of the guest:
Name, CPU, core, and reminiscence allocation
Full core or vCPU allocation
Architecture of the CPUs
Storage (local, iSCSI, NAS, FC)
When this information is combined with an operating system provisioning profile, the user can both create and provision one or more LDom guests quickly and easily by supplying a small amount of information, such as an IP address.
Further, the user can create a deployment map to create multiple LDom guests with a lone tide through the Ops heart user interface. After the deployment map has been created, it can breathe used very easily to quickly create a great number of VEs, each ready to evade a workload. Each of these guests will include total of the configuration details of the library image that was deployed, ensuring similarity for applications.7.1.4 Global Zones
Global zones can breathe used to host applications, Solaris Zones, or any combination of those. Within the context of Ops Center, for a ratiocinative domain to include zones, the “global zone” agent must breathe installed in the LDom.
The Ops heart user may create a Solaris Zone profile that defines how zones will breathe created. Configuration options include the following:
Dedicated or shared reminiscence and CPU resources
Type of zone (native or branded)
Source of installation (e.g., operating system archive or network-based package source)
Storage configuration (FC, iSCSI, or local disk)
IP/Network configuration (exclusive or shared)
Root and administration passwords
Again, the user can create a deployment plan, based on a zone profile, to create multiple similar zones.7.1.5 Storage Libraries
Ops heart tracks which LUNs and file systems are allocated to which guests, and ensures that more than one guest does not access the selfsame LUN simultaneously. This constraint applies to both environments created with Ops heart and existing environments that are discovered by, and integrated into, Ops Center.
Ops heart manages this storage by using an underlying storage concept called storage libraries. Storage libraries are shared storage that is used for VEs, either for boot or data storage. Three types of storage can breathe used for storage libraries:
A static library, using LUNs created ahead of time:
A dynamic library, using a ZFS storage appliance, creating LUNs as needed
Ops heart includes another feature for virtualization that greatly enhances the automation, mobility, and recoverability of both LDom and zone environments—namely, a server pool. A server pool is a collection of similar VEs. It can breathe a group of zones or LDom hosts (CDoms), but not both types. A server pool of Solaris Zones must include servers with the selfsame CPU technology, either SPARC or x86.
For a control domain server pool, Ops heart manages the placement of LDoms into physical computers using its own rules, guided by configuration information that the user provides and the current load on those computers. Ops heart can too dynamically poise the load periodically, among the servers in the pool.
A global zone server pool is treated the selfsame way: Ops heart runs the zones in the servers, or LDoms, according to its rules and configuration information.
A server pool consists of the following components:
Shared storage libraries (FC, NAS, iSCSI)
Shared networks—a very small NAS partake used to store guest metadata
The metadata comprises total of the information and resources for the guest. It is used for both migration and recovery scenarios.
Server pools enable two main mobility and recoverability features to breathe used in conjunction with virtualization—migration and automatic recovery.7.1.7 Migration
Guests can migrate between hosts within a server pool. Depending on the underlying virtualization technology, this migration will either breathe “live” or “cold.” In live migration, the guest VE is moved to the destination without any interruption of the VE’s operation. In contrast, artic migration requires stopping the guest and restarting it on another host in the pool. Ops heart provides a simple route to automate the safe migration of guests from the central browser interface. It performs preflight checks to ensure that a guest can migrate and that the migration will succeed prior to initiating the actual migration step.7.1.8 Automatic Recovery
Automatic recovery resolves a software or hardware failure without any user interaction. In the event of a server failure, guests on that member of the pool are automatically restarted on remaining, wholesome hosts in the pool. Each guest that is no longer running will breathe automatically restarted on a wholesome host in the pool.
For example, in a pool of five servers, imagine that Server 1 suffers a hardware weakness and stops responding. Ops heart will restart the guest(s) that had been running on Server 1 on the remaining servers in the pool. Ops heart uses internal algorithms to determine which hosts are wholesome and possess adequate resources. It uses placement rules provided when the pool was constructed to select the host on which each guest is restarted.7.1.9 Layered Virtualization
Ops heart supports and helps automate a very well-liked “layered” virtualization technology. In this technology, one layer of virtualization runs underneath another layer.
The pool administrator can create a CDom server pool, where multiple LDoms are partake of the pool. You can then consume Ops heart to create multiple zones in one or more LDoms (see design 7.2). If you consume layered virtualization, instead of migrating or automatically recovering at the zone level, those operations are handled at the LDom layer.
When you live migrate an LDom that has zones, the zones are automatically migrated with the LDom, and execute not tang any downtime. When an LDom is automatically recovered, the zones will too breathe recovered and restarted automatically.7.1.10 Summary
Virtualization technologies enable efficient consolidation, but require efficient management tools. Data heart staff can consume Oracle Enterprise Manager Ops heart to easily manage hundreds or thousands of VEs in multiple data centers, leveraging its efficient architecture to provision, monitor, and manage those guest VEs.
