Enterprise Manager 12.1 :Two System Upgrade approach

1. Start with existing 10.2.0.5 / 11.1 system

2. Apply the Upgrade console patch

3. Deploy 12.1 agents from upgrade console

4. Backup /restore the repository (Manually)

5. Deploy / configure OMS (can be on different host) and upgrade repository

6. Start the 12.1 OMS

7. Shutdown the 10.2.0.5 / 11.1 agents incrementally and activate12.1 agents

8. When all agents are successfully moved, decommission the pre-12.1 OMS

2- Systems Approach – how to restore old system?

1. You will have your old GC system intact. We don't touch your old OMS.

2. We don't touch your repository and it will be up and running

3. You have to manually start your old agent

4. You have your old GC back

Highlights of the new upgrade approach provided by Enterprise Manager 12.1

• You can plan your upgrade !

• NO downtime of your OMS during upgrade

• Reports ! Reports ! Various reports to give you overall picture of your upgrade. Reports will tell you if your environment is ready for upgrade and what is required

• Simplifies upgrade process by allowing direct upgrade from Enterprise Manager 10.2.0.5/11.1.0.1 to 12.1

• Provides a guided workflow for your complete upgrade process

• Easy fallback

Upgrading to Enterprise Manager 12.1

Phase 2

Phase 3

Phase 4

Phase 1 (Generic)

1.Review the Hardware/Software

requirements of 12.1

2.Review the Certification Matrix to

see if your repository and OS is

certified with 12.1

3.Apply the Patch 10044087 to

OMS home to get the Pre-upgrade

console

4.Create a shared location

(accessible from OMSes ) to store

your 12.1 agent binaries and

plugins

Phase 1 (Generic)

Global Marketing

Phase 1

• Read the Upgrade guide

• Go through the Hardware and Software Requirements of 12.1

• Go through the Certification Matrix for the repository and agent certification

– We had 10.1.0.4 repository with 10.2.0.5 Grid control. We upgraded it 10.2.0.5 before starting the upgrade to 12.1

• Apply the patch 10044087 to your OMS home to get the Pre-Upgrade console. Follow the Readme for patch application instructions

– OPatch utility version must be 10.2.0.0.0 or higher

• Created a shared location to store our EM 12c agent binaries and agents (i.e. via an NFS share)

What is Pre-Upgrade Console ?

This is the starting point of your Upgrade planning

Provides a guided workflow for your Upgrade

Single source of truth for upgrade impact(reports)

Agent Upgradability

Target Upgradability

Provides different upgrade approaches

Perform 12.1 mass agent deployment with required plug-ins (this is the agent upgrade)

We don't need any SSH connectivity to deploy the agents from the upgrade console as we use the existing agent communication(10.2.0.5 or 11.1) to transfer the bits

Software Management for 12.1 Agent and plug-ins

Runs dynamic pre-upgrade repository checks

Before 12.1 agents are activated administrators can run readiness checks

Phase 2

Identify Host and Port In this section, one must enter the

a)Fully qualified hostname where they plan to install the 12.1 OMS b)12.1 OMS HTTPS Upload Port c)12.1 OMS HTTP Upload Port

Note: You have to provide the same ports while doing the 12.1 OMS Install

Manage Software

1. Provide shared location and click “Validate”

2. Contents of Shared Location : Agent and Plugin software

3. Go through the reports

17

This version of OS will not be supported by 12.1 so the report clearly display the message. If you want this target to be monitored by 12.1 then upgrade your OS to a certified version

Phase 3

Global Marketing

Upgrade to Enterprise Manager 12c

Install Oracle Enterprise Linux 5.5 and have access to shared storage

After Deployment

Confirm that all servers can accept and respond to ICMP traffic (i.e. ping)

Install the latest oracle-validated RPM on target

system

Pre-upgrade steps have been completed from EM

12c Upgrade Console

Install the Oracle Database 10.2.0.5 software and restore your backed up 10.2.0.5 database

19

Backup your existing Grid control repository

• You can choose any backup mechanism ( cold/hot backup, dbca, RMAN ..etc) to back your existing grid control repository

20

Repository Backup Date & Time

Global Marketing

Invoke the 12.1 installer to upgrade your existing EM

• While you invoke the 12.1 installer it gives you upgrade options

• Select the correct option and provide the middleware home location. 12.1 Installer installs the WLS 10.3.5 along with 12.1

• The 12.1 OMS is similar to fresh install with upgraded repository

21

Global Marketing

Repository upgrade

• Provide the old (backed up) repository details and perform the repository upgrade

22

Global Marketing

Upgrade done

• Once the upgrade is done go back to the pre-upgrade console

23

Global Marketing

Create link to upgraded repository

• In the pre-upgrade console, provide the connect descriptor and click “ Create DB link”

• The location of the Connect Descriptor can be found at the following location:

$OMS_12c_HOME/gc_inst/em/EMGC_OMS1/emgc.properties

• Location assigned to variable EM_REPOS_CONNECTDESCRIPTOR

Agent Upgrades : Deploy and Configure

26

Mass Agent

deployment

Agent upgrades to 12.1 is out-of-place so you will get a fresh 12.1 oracle home. After deploying the 12.1 agent they are up and running but not uploading the data to 12.1 OMS

Global Marketing

Agent Upgrades : Deploy and Configure

• Integration with SUDO and Power broker

• Ability to run the script pre or post agent deployment

Generate Health Report

29

Health report does various checks on the 12.1 agent before it starts uploading the data to 12.1 OMS It also does the ping check between the 12.1 agent and 12.1 OMS
