Overview
• Goals
– Stable EM Solution
– Get new
features/updates
• Challenges
– Updates cost
– Do you have SLA on
EM?
– Will patches be
successful?
4. sysco.no
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)
5. 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
6. 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
7. sysco.no
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)
Configuration

Patching EM Cloud Control
• You can use EM to patch EM
• First you need to setup
connection to Oracle Support
• You may need to add proxy
Patching
10. sysco.no
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

12. sysco.no
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
13. sysco.no
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
15. 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
16. 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
17. 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
18. 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
19. 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 same
bundle patch version
