Performance

• Have sufficient memory and cpu!

• Disk access must be fast!

• Previous version 12.1.0.2 of EM had «Performance Patch

Bundle»

• If you are on older version – upgrade (or new install)

sysco.no

What to do after fresh install?

• Read Note Oracle Enterprise Manager 12c Configuration

Best Practices (Doc ID 1553342.1)

• OMS

– If you have more than 250 agents, increase the -Xmx

parameter (maximum size) for the java heap to 2 gb

Configuration

sysco.no

Configuration Best Practices

• Repository Recommendations

– Repvfy execute optimize: establishes a baseline and sets the

environment to the “recommended” values based on the config

– Increase Task Workers – Check that there is no backlog

– Increase Ping Grace Period – When 100’s or 1000’s of agents

– Maintaing Audit Data: Initialize audit trail cleanup, set archive

timestamp for audit records, create purge job

Configuration Best Practices

• Agent

– Steps to Tune the Cloud Control 12c Agent Performance When

Monitoring a Large Number of Targets (Doc ID 1349887.1)

– enableAutoTuning=true (default on)

– FMW: -Dweblogic.ThreadPoolPercentSocketReaders=80

-Dweblogic.ThreadPoolSize=XX

(SOA may have lot of targets – and agent may die if not adjusted)

Patching EM Cloud Control

• You can use EM to patch EM

• You may need to add proxy

Patching

Patching EM Cloud Control

• Or you may need to change in firewall – check note:

Cannot Connect From 12c Cloud Control To

https://updates.Oracle.Com (Doc ID 1436653.1)• At minimum, the following URLs should be made available through the

firewall:– aru-akam.oracle.com– ccr.oracle.com– updates.oracle.com– login.oracle.com– support.oracle.com

Patching EM Cloud Control

• Do not use your personal MOS

account – must have access to all

• Force an update

Patching

Upgrading Agents

• Agents are versioned – for example 12.1.0.3

– Bundle patches have version number for example 12.1.0.3.9

• Upgrading a Management Agent modifies its installation

base directory structure

• Done from CLI or

console

Patching

Patching Agents / Plugins

• Enterprise Manager 12.1.0.3 Bundle Patch Master Note (Doc

ID 1572022.1)

• Current bundle patches

• Bundles released last day

of the month

Patching

Patching Agents

• Management Agent

• Recommended vs.

not recommended (as in you do not have to)

Patching

sysco.no

Patching WLS

• EM suggests WLS patches – PSU and other

• Cannot patch OMS WLS from console, must use CLI

• Patching WLS in OMS would require WLS Mgmt Pack

Patching

sysco.no

Experiences

• Patching OMS using CLI (OPatch)

• Patching Agents/Plugins using Console

• Patching WLS using CLI (bsu)

– The OMS is running on the WLS

• Patching OMS sometimes takes long time (plugins)

• You do not get patching advisory for Plugins, only Agents

– But in 12.1.0.4 you do

Patching

sysco.no

Recommendations

• Set up named credentials / preferred credentials

• Create relevant groups used for patching

• The Groups will give relevant Patch advise

• The Groups will help you to patch with fewer steps

• Separate groups in Dev, QA, Prod so that you can test on a

smaller number of targets first

Patching

sysco.no

Recommendations

• Decide on a patching strategy

– Decide on if you will patch each month, quarterly, 2X per

year ?

– Will you patch as soon as a patch is available ?

• Look at cost/benefit

Patching

sysco.no

Sequence

• Patch OPatch on OMS (11.1)

• Apply latest PSU to OMS

• Apply latest WLS Patch

• Apply latest patches to plug-ins OMS-side

• Apply latest agent patches

• Apply latest patches to plug-ins agent-side

– Plugins may have two patches, ex Discover + Monitoring, not necessarily in
