PowerVC 1.3.1 - Virtual Application management of an Oracle Database 12cPowerVC is able to replicate (capture and deploy) Oracle Database 12c with the following capabilities:

• Capture an Oracle E-Business AIX Power installation in shutdown mode. Using cloud init tools or PowerVC activation engine.

• Little pre-capture manipulation required, just stop the database and listener.

• Fast deploy of multiple disk virtual appliance (VA) using OpenStack services.

• Multiple deployment of the same captured VA, greatly reduced deployment time.

• No manual reinstallation of Oracle Database 12c and fixes.

• Single step configuration at post deployment to have the database ready for use.

• Greatly reduced manual intervention of replication of an Oracle Database 12c environment, multiple redeployment on demand at short notice. Little or no chance of human error when replicating environments.

PowerVC 1.3.1 – Oracle Database 12c ProvisioningElapsed time comparison of provisioning using IBM PowerVC 1.3.1 over traditional manual provisioning.

The initial Oracle Database 12c will still need be manually installed, following the Oracle documentation, but subsequent provisioning timeline using PowerVC 1.3.1 is greatly reduced.

What is OpenStack?OpenStack is a set of software tools for building and managing cloud computing platforms for public and private clouds.

Backed by some of the biggest companies in software development and hosting, as well as thousands of individual community members, many think that OpenStack is the future of cloud computing.

OpenStack is managed by the OpenStack foundation, a non profit organization which overseas both development and community-building around the project.

Refer to the following links for more information:

IBM is a Platinum member of the OpenStack community.

PowerVC Virtual Appliance management of an Oracle Database 12c workloadProject scope:

Install PowerVC 1.3.1 on POWER8 RHEL 7.1.

Configure PowerVC 1.3.1

Capture a virtual image of the desired Oracle 12c database

Deploy the virtual image of the Oracle 12c Database.

Perform the post deployment steps and startup the Oracle 12c database

• Install PowerVC1.3.1 on Power Systems server with POWER8 processors and RHEL 7.1.

• Configure PowerVC1.3.1 and import the Power Systems server environment, communication to PowerVM, and the HMC, identifying storage, compatible lpars.

• Identify the LPAR to be captured, stop the Oracle Database, and use PowerVC1.3.1 to capture the virtual image. Use cloud init prior to capture to set the deployment characteristics. Capture all disks associated with the LPAR.

• Deploy the virtual image (VM) to a new LPAR name.

• Set the IP address and system name of the new LPAR, and update the listener tnsname to the new LPAR. Startup the database.

PowerVC can be installed in both Standard and Cloud versions.

It is necessary to configure the RHEL 7.1 Linux environment for YUM support prior to installation as the installation will need to install dependent packages from the standard RHEL iso image. (standard installation is version 1.3, with an additional fix pack).

Installation of the ‘Manage from’ PowerVC environment can will be on Power Systems server PPC.

Resource Monitoring and Control (RMC) is required to communicate to the HMC, only if this is running on a Power Systems server with processors prior to POWER8.

On Redhat Linux this is not part of the standard iso build. Additional packages need to be installed. These packages are included in the IBM Tools for Linux repository.

The IBM Tools repository can be sourced from the following website:

https://www-304.ibm.com/webapp/set2/sas/f/lopdiags/home.html

Further information about RMC can be found at the following website:

PowerVC installation and configuration involves importing definitions of the following Hardware management Console (HMC) devices.

Configure PowerVC to the HMC.

• HMC source

• Hosts

• Storage and fabrics

• Networks

• Virtual machines (compatible)

PowerVC is able to import definitions of all dependent devices on the defined HMC, categorized by host.

After defining the host system, there is a flag to turn on Novalink for all other communications, therefore removing the need for communication via the HMC (POWER8 only).

Identify the source Oracle 12c Database.

Identify source Oracle Database 12c (VM) which is to be captured.

This VM will need to have the following installed:

•PowerVC activation engine, or Cloud Init. Either can be used. (recommendation is to use Cloud Init).

• Ability to be shutdown for the capture process.

Multiple disk installations.

PowerVC 1.3.1 is able to support multiple disk installations.

Prepare using Cloud Init.

The recommended VM preparation method is to use Cloud Init.

Download the cloud init software from the following Url: ftp://public.dhe.ibm.com/aix/freeSoftware/aixtoolbox/RPMS/ppc/cloudinit and refer to the readme file for installation instructions.

Copy the files to the lpar to be captured.

Change the permissions on the cloudinit.sh file using ‘chmod 777 cloudinit.sh’.

Run the script command cloudinst.sh to query the status of the dependent packages.To install, run the following command: .’/cloudinst.sh –o install’. Ensure all packages are installed successfully.

The installation script will also install any package dependencies. Ensure the script completes without error.Navigate to /opt/freeware/etc/cloud/cloud.cfg and make any necessary modifications.

Capture the VM from within PowerVC.

Highlight the VM, click on capture, enter the new image name, and allow PowerVC to complete successfully. The image will be saved in the Virtual image library (VIL) and is referred to as a Virtual Appliance.

Select the disk configuration to be captured.

Deploy the virtual appliance.

Deployment of the Virtual Appliance is simply a case of selecting the VA, and giving it a new unused IP address within the selected network. PowerVC will then deploy the VA to the selected HMC host.

As part of deployment, it is possible to set the number of processors, memory allocation and storage settings.

When deployment is complete, the new VM will be activated, and the activation engine in the VM will configure the network and allocate the required disk. If multiple disks were assigned, then these will be attached as symbolic links.

Ensure the new lpar is allocated at least the same number of processors and memory.

Additional disk volumes can be added at any time in the future.

If deployment fails then PowerVC will log any issues. Investigate these if any, and attempt to redeploy. https://www.ibm.com/support/knowledgecenter/SSXK2N_1.3.0/com.ibm.powervc.standard.help.doc/powervc_troubleshootingforproduct_hmc.html

Post deployment steps.

Post deployment steps:

• IOCP – Tune the IOCP parameter, it must be set to ‘available’. Use the command smitty iocp to check / change this value.

• Oracle Database listener – edit the listener.ora file in /$ORACLE_HOME/network/admin to reflect the new system ip address or system name.

• Hosts – check the hosts file in /etc.

• Start the database, listener and check with:https://<fqn>:5500/em

IBM PowerVC1.3.1- NovalinkNovalink for performance advantage.

Novalink is built into the PowerVM product for Power Systems servers with POWER8 processors. It provides a performance advantage in that it communicates directly with PowerVM, and bypasses the hardware management console (HMC) for resources.

Novalink also manages the OpenStack services on the ‘manage From’ server used to run the PowerVC cloud.

Other features of PowerVC 1.3.1Other features of PowerVC 1.3.1 are:

• Dynamic Resource optimizer (DRO).If enabled on the host system, the optimizer will try to resolve any resource issues without the need for use intervention. Any changes are logged and are visible through the PowerVC dashboard.

It is also possible to exclude individual virtual machines from DRO.

• Compute Templates.These can be pre configured and used to build a standard base environment either manually, or using automated, ‘silent’ configuration.

• Project groups.Users can be allocated to project groups with can be restricted to certain host and resources, this also includes functional abilities.
