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.
