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 everyone the time been an help path that necessary to live adopted with the aid of the clients.
there are lots of who are overconfident and blindly rush in as quickly as a brand new 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, antecedent catastrophe, which might live plenty stern when it comes to a enterprise or business environment. perquisite 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 net add-on features like database options and administration packs with complete exploration of the server supplies.
Oracle Database 12c - general 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 assist 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 headquarters of attention extra on the route to disburse the Database upgrade Assistant, which is a established method 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 oversight without delay from the DBUA, and moreover, it makes monitoring the upgrade tons less difficult and in actual-time. as a route to disburse DBUA, clients deserve to entry the domestic page of Oracle Database 12c and start by means of running the DBUA. The ultimate succeed is to dash the preupgrd.sql to peer what can furthermore ought to repair before operating the assistant.working PREUPGRD.SQL
For running ‘preupgrd.sql’, one first must deploy new binaries into Oracle DBA home. once that is executed, set up the atmosphere to connect it to the database obligatory to live upgraded.
As a sample, they can engage 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/18.104.22.168/dbhome_1/rdbms/admin
After this, they ought to connect the 11g database with SQL*Plus to dash preupgrd.sql#>sqlplus / as sysdba SQL>@preup grd.sql
After running the script, they will net the file places, which can live obligatory for reference to examine and remedy any considerations with the ambiance later.
The consequences of this examine may live observed at:/decide/oracle/cfgtoollogs/ora11/preup grade/preup grade.log
The pre-upgrade repair-up script dash at the source database atmosphere is:/choose/oracle/cfgtoollogs/ora11/preup grade/preup grade_fixups.sql
The submit-upgrade repair-up script dash 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 remedy if anything requires extra fixes. once these fixes are done properly, working DBUA will develop into an abominable lot more straightforward. The mistakes listed in preupgrade.log furthermore obligatory to live 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 dash the DBUA:#> cd/choose/oracle/product/22.214.171.124/dbhome_1/bin #> ./dbua&
working this will initiate the GUI to birth instantly and net upgraded. There is not any deserve to trade anything within the atmosphere, which could nevertheless live 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 succeed 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 live upgraded. As we've it set to 11g domestic, during this case, the DBUA will disclose everyone databases associated with the 11g Oracle home. opt for which database needs to live upgraded and click subsequent.Step three
The effects may well live similar to what they noticed at preupgrade.log. The DBUA is furthermore working the same preupgrd.sql script and should recur with the results. however, the helper is made to live extra shrewd with the capacity to permit users to pick whether the considerations to live fastened, overlooked, or revalidated.Step four
Oracle has made a captivating exchange here as the help can live 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 win the tablespaces examine-simplest as the upgrade runs.Step 5
This step will enable clients to control the Oracle Database 12c environment. you could disburse EM specific or can register the DB with OEM 12c (Oracle commercial enterprise supervisor). The DBUA will instantly pick on the necessary recommendation if OEM12c brokers are already installed on the server.Step 6
clients can specify the status the data data deserve to live 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 assist 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 live migrated.Step 8
Now, clients possess the option to create a backup of the database before the upgrade runs. that you would live able to additionally teach the DBUA by means of determining a radio button now not to Do 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 win confident that every exiguous thing is so as earlier than clicking the ‘conclude’ button to birth the upgrading method. once clicked, the upgrade will delivery and they will espy 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 espy 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 furthermore 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 headquarters and OpenStack can facilitate the process of automating virtualization.This chapter is from the engage
Early computers were expensive, prompting their owners to squeeze everyone practicable value out of them. This drive led to the introduction of time-share operating systems, on which many workloads may dash at the same 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 towering 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 headquarters and OpenStack.
Oracle Enterprise Manager Ops headquarters 12c is portion of the broader Oracle Enterprise Manager product. Whereas Enterprise Manager Cloud Control focuses on the higher terminate of the stack (i.e., database, middleware, and applications), Ops headquarters addresses the lower terminate (i.e., storage, operating systems, hardware, and virtualization).
Ops headquarters is designed for replete 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 new and existing hardware
Upgrading server firmware
Installing the “bare metal” operating system
Monitoring hardware components and opening service requests automatically if a hardware fault 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 headquarters 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 headquarters will possess at least one enterprise controller system that provides communication back to Oracle for service requests, automated patch and firmware downloads, constrict 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 affect 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 everyone of the systems being managed by Ops headquarters are in one data center, only one proxy controller is needed, and it can dash in the same server as the enterprise controller. Alternatively, you can install multiple proxy controllers per enterprise controller. standard configurations disburse one or more proxy controllers per data center, to expand the compass of the Ops headquarters 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 live managed without one. The Ops headquarters agent supports Solaris 8, 9, 10, and 11.
Figure 7.1 depicts the Ops headquarters architecture.7.1.2 Virtualization Controllers
The Ops headquarters administrator can pick from two types of virtual environments. One ilk uses Solaris Zones; this ilk is simply called a global zone. The other ilk is a control domain, whose designation refers to the disburse of OVM Server for SPARC. everyone systems that can live managed by Ops headquarters can live the global zone type. On modern SPARC systems, you can pick either a control domain or a global zone.
After you win that choice, Ops headquarters deploys the appropriate ilk 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 appropriate ilk of VEs on that server: rational 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 rational domains (LDoms) on a computer. When you disburse Ops headquarters 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 furthermore 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 knotty domains, are furthermore supported.
Once the CDom is provisioned, the Ops headquarters user can initiate 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 headquarters user creates one or more rational domain profiles that define the make-up of the guest:
Name, CPU, core, and recollection 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 draw to create multiple LDom guests with a lone rush through the Ops headquarters user interface. After the deployment draw has been created, it can live used very easily to quickly create a great number of VEs, each ready to dash a workload. Each of these guests will include everyone of the configuration details of the library image that was deployed, ensuring similarity for applications.7.1.4 Global Zones
Global zones can live used to host applications, Solaris Zones, or any combination of those. Within the context of Ops Center, for a rational domain to include zones, the “global zone” agent must live installed in the LDom.
The Ops headquarters user may create a Solaris Zone profile that defines how zones will live created. Configuration options include the following:
Dedicated or shared recollection 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 headquarters tracks which LUNs and file systems are allocated to which guests, and ensures that more than one guest does not access the same LUN simultaneously. This constraint applies to both environments created with Ops headquarters and existing environments that are discovered by, and integrated into, Ops Center.
Ops headquarters 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 live 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 headquarters 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 live a group of zones or LDom hosts (CDoms), but not both types. A server pool of Solaris Zones must include servers with the same CPU technology, either SPARC or x86.
For a control domain server pool, Ops headquarters 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 headquarters can furthermore dynamically balance the load periodically, among the servers in the pool.
A global zone server pool is treated the same way: Ops headquarters 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 participate used to store guest metadata
The metadata comprises everyone 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 live 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 live “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 headquarters 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, healthy hosts in the pool. Each guest that is no longer running will live automatically restarted on a healthy host in the pool.
For example, in a pool of five servers, imagine that Server 1 suffers a hardware fault and stops responding. Ops headquarters will restart the guest(s) that had been running on Server 1 on the remaining servers in the pool. Ops headquarters uses internal algorithms to determine which hosts are healthy 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 headquarters supports and helps automate a very accepted “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 portion of the pool. You can then disburse Ops headquarters to create multiple zones in one or more LDoms (see design 7.2). If you disburse 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 Do not suffer any downtime. When an LDom is automatically recovered, the zones will furthermore live recovered and restarted automatically.7.1.10 Summary
Virtualization technologies enable efficient consolidation, but require efficient management tools. Data headquarters staff can disburse Oracle Enterprise Manager Ops headquarters to easily manage hundreds or thousands of VEs in multiple data centers, leveraging its efficient architecture to provision, monitor, and manage those guest VEs.
