Get Compliant with Oracle Java VM Database PSU OCT 2014 using EM12c

Check for compliance and automate patching of Oracle Database fleet using EM12c

Oracle along with its regular Quarterly Database PSU/SPU/CPU update this October 2014 released Oracle JAVA VM PSU patch, the patch is recommended to be applied to all databases in your fleet (esp. the ones that uses JAVA).  (For more information, support Note- 1929745.1 explains it in detail).
The mandate primarily is to apply the patches against the databases that use JAVAVM option. Ideally, you would need to apply it against all databases, so in case a new database is created in the ORACLE_HOME it is covered.

Oracle Enterprise Manager 12c provides support features of Compliance Management and automated Patching of databases. Using both these features you could identify the databases in your fleet that needs the patch and automate applying them.  

To get started, download the starter kit here. It contains utilities to jump start on your compliance, the kit contains a readily importable Compliance Standard and a step-by-step guide.

Reducing Downtime While Patching Multi-OMS Environments

Enterprise Manager has now been released for a few weeks, as well as the OMS Bundle patches (also known as System patches). If you plan to apply these bundle patches to your OMS, and you are concerned about the downtime, then, you can reduce the downtime by referring to this whitepaper that contains patching instructions to reduce downtime. 

This whitepaper covers various Enterprise Manager High Availability (EM HA)  usecases (level 1, 2, 3, 4), and contains instructions on how to reduce downtime while applying patches to each of these usecases. It also clearly defines the steps that require downtime and those that do not.

If you have a multi-OMS setup, you can also refer to this whitepaper which covers script creation using the opatchauto command, which automates the substeps and further reduces downtime.During our internal testing of this whitepaper on an EM HA setup, we have noticed a significant reduction in downtime. 

If your customer plans to do an Enterprise Manager Upgrade to, then as a post upgrade recommendation, they should patch their OMS with the latest bundle patches by following the instructions outlined in this whitepaper.

Reduce Oracle Enterprise Manager 12c Patch Set Upgrade Downtime

As Product Manager for Oracle Enterprise Manager, one question that is often being asked to me is how much is the upgrade downtime and how it can be reduced? 

One easy way to reduce the downtime while doing patch set upgrades is to perform Software only upgrade and then shutdown the existing OMS for the upgrade. This approach will not completely eliminate the downtime but reduce it to a great extent. 

When I mention patch set upgrade, we cover following upgrade paths:

a) (with Bundle Patches 1) to

b) to

Following table compares the steps required for regular installation (OUI) and software only installation.

 As you may notices from the steps listed above, regular OUI upgrade requires stopping OMS before invoking runInstaller and keeping it down until the upgrade is complete. On the other hand Software only upgrade first copies the bits and sets up the environment before stopping OMS, thus reducing the upgrade downtime.

Next comes Agent upgrade. While we recommend Agent Upgrade Console (AUC) to upgrade agents from (with bundle patch1) / to, sometimes it’s not clear what happens during the Agent upgrade and when is the actual downtime . So here are high level steps describing the complete process: 

The actual downtime while doing the agent upgrade is on step9 where we shut down your old agent. When the agent is in blackout from step 1 to 8 it still collect’s all the monitoring data so there is no loss. 

More Information: It is recommended to go through the below checklist notes before starting your upgrade
