Disaster Recovery OMS Setup

DR is using storage replication methodology for EM with alias host names back in 12.1.0.2

Our own custom setup role based service on primary instance(s) to control OMS start/stop

srvctl add service -d REPOS -s OMS_PRIMARY -r “REPOS1,REPOS2" -P BASIC -l PRIMARY

• We deployed a fan script to automatically start/stop OMS on the primary nodes based on the state of the primary service above.

• We commented out default OMS restart script since we don’t want DR to automatically start

• Only need to run data guard switchover/failover command to perform all operations

Ha Setup continued


User Administration

8

10/28/15 9

OEM UI

Each user takes about 15 mouse clicks

Time consuming for large number of users

EMCLI create_user

Generate your user create script

Allows for batch processing of user creation

LDAP-authenticated accounts

Auto-generated accounts ease administration

LDAP groups matching EM roles ease authorization

Methods to Create OEM User Access

10/28/15 10

• Adding new users

• Changing access through job changes

• Removing users for exiting employees

User Management and Security Compliance

10/28/15 11

Configure WebLogic

Use WebLogic Admin Console

Create Active Directory Authentication Provider

Set OMS Properties

oracle.sysman.core.security.auth.is_external_authentication_enabled

oracle.sysman.emSDK.sec.DirectoryAuthenticationType

Ease User Creation with Auto Provisioning

Use OMS Property:

oracle.sysman.core.security.auth.autoprovisioning

Link OEM with Active Directory

10/28/15 12

Create OEM Global Roles

10/28/15 13

Patch Automation

Steven Meredith, 12/31/2015 | 15

Patch automation for database consolidation environments

▪ Scope: Consolidation RAC database clusters

▪ PSU patching required quarterly for all consumers

▪ Customers span all business units within Boeing

Challenges

▪ Patch schedule consolidation to maximize scalability

▪ Process design to meet patching requirements for clustered databases

▪ Operational discipline to maintain healthy and accurate target configurations



Patch Plan Screen Shot


This plan patched 27 3-node

cluster databases (81 instances)

while leaving 9 cluster db’s on the

previous home



Patch Automation


Benefits

▪ Significant Labor reduction but short of initial goal

– Some customers not able to support unified patch schedules

▪ Enhanced productivity for patching focals

▪ Decreased patch cycle times

▪ Improved validation

▪ Configuration changes consistently deployed and maintained within oracle homes

▪ COTS vendor support for emergent patching changes

▪ Consistent patching process



Patch Automation


Key Tips/Take Away’s

▪ Understand the features and limitations of the product

▪ Analyze your environment and determine how automation will fit

– Deployment patterns and standardization are key factors in scalability

– Also evaluate organizational discipline in maintaining EM target health and configuration

▪ Set realistic goals

– Consider phased implementation

▪ Have a backup patching plan

▪ Get continuous and strong management support

▪ Communicate successes, challenges and sometimes failures
