New Book Just Released
Personal Experience with My Oracle Support
• Lone DBA at a University of 8,000 students • 110 Targets in Grid Control • All Targets have Configurations in My Oracle Support • Used Configurations since Alpha and Beta Release• Consider My Oracle Support …My Backup DBA as
well as a Disaster Site Document Repository
Oracle Configuration Manager
• Manage automatic uploads to MOS • Viewable with same CSI number• Contains details about hardware, software,
databases and application servers• GUI interface along with configurations
provide a personalized visit to MOS• New Mass Deployment Utility for OCM
deployment
OCM Mass Deployment Utility
• Version 3.2+• Found on the MOS collector tab –
Configuration Manager Repeater and Mass Deployment Tools
• Find the OCM Companion Distribution Guide.• Edit csv template file to enter all servers• Executed on a single node with ssh access to
entries in template
OCM Install in Oracle Universal Installer
RDA, Service Requests
• Oracle Support Engineers use uploaded configuration
• May still ask for an RDA output • Recommendation: Customize your RDAs to
eliminate sensitive information
11g Diagnosability Framework
• Support Workbench in OEM dashboard • Automatic Diagnostic Repository Utility –
adrci• Package, upload problems or incidents • Integrated with OCM for the uploads
Use OCM Securely
• Use disconnected mode with Oracle Support Hub
• Manual upload of a single node • Mask IP, MAC addresses, Schema
usernames• Request deletion of configuration information
GC 10g- Single EM Harvester instead of OCM collectors • Collecting and uploading configuration data to
My Oracle Support • White paper – MOS Doc ID 848962.1• Requires OMS 10.2.0.5, connected mode• Only need to install OCM in the OMS home,
not all of the targets.• No database PL/SQL install required• Will work with older agents • Supported configurations – Hosts,
ORACLE_HOMEs, Database, OAS
Patching Issues Facing DBAs • Patch Conflicts – Rollbacks
– No advance notification there is a Conflict
• Troubleshooting Patch Application Failure– Hours needed to resolve a failure
• CPU’s and PSU’s – conflicting– What to install when ?
• Recommended Patches– Am I the first person to deploy this patch ?
• Merge Requests– Am I the first person to request this Merge?
• Documenting– Many ad-hoc vehicles to document install patches
Based on polling DBAs on Oracle-L
Issues with Conflicts and Rollbacks
Without My Oracle Support
• Download patch then…
• Install….if conflict then…
• Check if any key patches rolled back…if rolled then….
• Merge request…..then
• Wait….might be too late for this CPU, narrow window….maybe next quarter!
With My Oracle Support
• Patch Plan
• Auto checks prerequisites
• Checks Conflicts before downloading
• Request Merge before downloading
• Check Recommendations
• Deployment Plan Available
MOS V3.2 Addressing DBAs Needs
No download or install needed
Merge request may already be available if previously requested….not having to download would save bandwidth, time and wasted effort just to test for conflict.
No download or install, merge request might already be available, one click request, no SR. Patch plan=Maintenance window
Troubleshooting Patch Application Failure
No configurations Uploaded to Oracle
• Most nodes have unique patch history due to hardware rotations
• Usually requires a Service Request
• Completely manual process
• May take weeks to resolve
Oracle Configuration Manager and My Oracle Support
• Fewer Patch Install Attempts
• Less Failures
• Less Time Wasted
• Less stumbling blocks to getting the patch process completed
Recommended Patches
No configurations Uploaded to Oracle
• Manual Process
• No patch plans available
• Time Consuming
• Patches are not diligently applied on a timely basis due to time and effort
Community and Oracle Recommended Patches
• Community Reviews
- Customers Experience
• Download Statistics
- Is it considered important?
• Upgrade Companion
- Recommendations Listed
• Tested as a single unit
- Targeted Configurations – Business Suite, Database, OAS
Bugs fixed by this patchSee download trends and community feedback
SUU expects to save at least 50% of the time spent reviewing and deploying patches from 4 hours/week to <2. Moving to more secure model of patching consistently on a quarterly basis.
Documenting Versions and Patches
No Configurations Uploaded to Oracle
• opatch ls inventory –detail | grep patchno
• Spreadsheet on a single desktop
• Perhaps uploaded to IT Wiki or Intranet
• Possibly no documentation
Oracle Configuration Manager and My Oracle Support
• Patch Plans will contain all current information
• Configurations will also contain version information
• Requires a collector install then auto uploaded on a daily basis
• Not dependable yet
PSUs vs. CPUs Oracle Recommendations • Apply PSUs from now on (since DB Version
10.2.0.4) • Both CPU & PSU Released Quarterly• PSUs include CPUs• PSUs are a Superset of CPUs• Might need merge patch if migrating from a
CPU • Don’t revert back to CPU once on PSU – this
can be a insurmountable technical obstacle.http://blogs.oracle.com/gridautomation/
OMS GC 11g Differences
• GUI Flash-based• GC Integrated with My
Oracle Support• Requires WebLogic Install
OMS 11g - Still not officially available
Note the Upgrade Option
Kept with defaults
Recommended or Required? Halts process if not installed.
Partitioning License included with GC, no extra cost
Take a snapshot of this screen for port assignment
First Time OEM GC Login
MOS tab on OMS11g GC console
Different than normal MOS login – missing favorites??
Not sure why? Once supported I will enter an SR. Maybe the functionality just isn’t there yet.
Nice red tag for remainder of session
Agent Clone GUI Interface
Questions??
Leave Business Card – put question or interest on back.
