Upgrade OEM 12c to 13c
Here, in this article, I’m demonstrating an upgrade from cloud control 12c to 13c on a linux machine. It is required to take a look at the https://docs.oracle.com/cd/E63000_01/EMUPG/preface.htm#EMUPG101 upgrade document before proceeding further and make sure that all the pre-requisites are met.
Few things to consider before you proceed with the upgrade.
1. OMS 13c repository database needs to be on 12.1.0.2 version. So, if the repository database is on a pre-12c release, then you need to upgrade it before upgrading the Cloud control.
2. Cloud control 13c is not supported on OEL/RHEL 5 and so are the 13c agents. You cannot upgrade cloud control 12c on linux machine less than version 6 to 13c.
Environment details is as below:
The environment used here has the Cloud control 12c installed on OEL 6 with the repository database of version 12.1.0.2 which is a non-CDB and has the 12c agents deployed on linux machine of release 6 (OEL 6).
Cloud Control 12c OMS hostname: ora1-2 Repository database version: 12.1.0.2
Make sure that the “COMPATIBLE” parameter on the OMS respository database is set to 12.1.0.2.0.
SYS@omsdb> show parameter compatible NAME TYPE VALUE ------------------------------------ ----------- ------------------------------ compatible string 12.1.0.2.0 noncdb_compatible boolean FALSE SYS@omsdb> SYS@omsdb> show parameter adaptive
If the adaptive optimizer feature (optimizer_adaptive_features) is enabled, then it needs to be disabled on the OMS repository database before upgrading it.
NAME TYPE VALUE ------------------------------------ ----------- ------------------------------ optimizer_adaptive_features boolean TRUE optimizer_adaptive_reporting_only boolean FALSE parallel_adaptive_multi_user boolean TRUE SYS@omsdb> SYS@omsdb> alter system set optimizer_adaptive_features=false; System altered. SYS@omsdb> show parameter adaptive NAME TYPE VALUE ------------------------------------ ----------- ------------------------------ optimizer_adaptive_features boolean FALSE optimizer_adaptive_reporting_only boolean FALSE parallel_adaptive_multi_user boolean TRUE
If there are any invalid objects in the OMS Repository database, then those need to be validated.
Take a backup of the current OMS. Refer the documentation “http://docs.oracle.com/cd/E24628_01/install.121/e24089/ha_backup_recover.htm#EMADV9639” on how to backup the OMS.
Copy the EMKEY from the exsting OMS to the existing management repository. EMKEY is the encryption key which is used by Enterprise Manager to encrypt/decrypt sensitive data such as passwords, preferred credentials.
[oracle@ora1-2 ~]$ echo $OMS_HOME /u02/oms12c/oms [oracle@ora1-2 ~]$ $OMS_HOME/bin/emctl config emkey -copy_to_repos Oracle Enterprise Manager Cloud Control 12c Release 4 Copyright (c) 1996, 2014 Oracle Corporation. All rights reserved. Enter Enterprise Manager Root (SYSMAN) Password : The EMKey has been copied to the Management Repository. This operation will cause the EMKey to become unsecure. After the required operation has been completed, secure the EMKey by running "emctl config emkey -remove_from_repos". [oracle@ora1-2 ~]$ $OMS_HOME/bin/emctl status emkey Oracle Enterprise Manager Cloud Control 12c Release 4 Copyright (c) 1996, 2014 Oracle Corporation. All rights reserved. Enter Enterprise Manager Root (SYSMAN) Password : The EMKey is configured properly, but is not secure. Secure the EMKey by running "emctl config emkey -remove_from_repos". [oracle@ora1-2 ~]$
Stop all the components of OMS which includes WebTier, OMS and AdminServer.

Stopping WebTier... WebTier Successfully Stopped Stopping Oracle Management Server... Oracle Management Server Successfully Stopped AdminServer Successfully Stopped Oracle Management Server is Down [oracle@ora1-2 u03]$
If there is an agent configured for the OMS server, then stop that too.

Copy all the EM13c software parts into a staging directory. I have them copied into directory “/u03/em13csoftware”.

Set the executable permission on the file “em13100_linux64.bin” which is the executable binary file.
Execute the em13100_linux64.bin file to invoke the 13c GUI component.
[oracle@ora1-2 em13csoftware]$ chmod +x em13100_linux64.bin [oracle@ora1-2 em13csoftware]$ ls -lrt em13100_linux64.bin -rwxr-xr-x. 1 oracle oinstall 841114290 Jun 11 16:20 em13100_linux64.bin

Provide the mail ID followed by password if you wish to receive the support updates and click NEXT.
I would not like to search for the software update and hence chosing the SKIP option and clicking NEXT.
Run the pre-requisite checks and if any discrepancy, then fix them before proceeding further.
Since we are upgrading to 13c EM, select the “Upgrade an existing Enterprise Manager system” option and under this select the “One-System Upgrade” by selecting the 12c EM home.
Enter the middleware home location. I’m installing 13c under the location “/u02/13c”.
Oracle automatically captures the connect description details for the repository database. Provide the SYS and SYSMAN password.
Also confirm that the Management Repository is backed up by checking the box. If you wish to stop the Enterprise Manager for post-upgradation maintenance, then check the “Disable DDMP jobs” and click NEXT button. In that case, the post-upgradation maintenance activity needs to be carried out manually. DDMP is Deferred Data Migration which is to migrate the format of the data from the previous release Enterprise Manager to the format used in 13c.
If there are any pre-requisite checks at OMS repository database level failed, then review the recommendations provided. Click YES, if you would like the installer to take necessary actions else NO for a manual fix.
Review the information on the plugins that will be upgraded and click Next.
Select the additional plugins that you want to deploy and click Next.
Fill in the WebLogic server details by specifying the password for the Weblogic User Name and also providing the OMS Instance Base Location.
If you want to configure and enable BI publisher, you can select it here, else click Next.
Review the default ports listed and click Next.
Review the list of information provided and click on Upgrade to begin the upgrade.
Run the “allroot.sh” script as ROOT user when prompted.
[root@ora1-2 ~]# /u02/13c/allroot.sh Starting to execute allroot.sh ......... Starting to execute /u02/13c/root.sh ...... /etc exist /u02/13c Finished execution of /u02/13c/root.sh ......
Review and note down the URLs
Login to the EM 13c through the browser with SYSMAN as the user and the password which was being used previously.
Accept the License Agreement to proceed further.
Review the OEM 13c summary page.
If you had disabled DDMP jobs while upgrading EM, you should consider to carry out the post upgrade tasks.
Login to the EM 13c through the browser. On the summary page, click SETUP. Under this, select “Manage Cloud Control” and then the “Post Upgrade Tasks” option.
Click the “Start” option to start the post upgrade tasks.
Review the status of the post upgrade tasks.
Upgrading a 12c agent to 13c:
As said previously, 13c agents can be configured on a Linux target machine whose version is not below 6. So, if you already have the 12c agent installed on a Linux machine which is less than version 6, then this cannot be considered to upgrade to 13c agent. But, you can still use the old agent (12c agent) with EM 13c.
For the purpose of this demo, I had a 12c agent installed on my OMS host which is of version 6. So, I’m considering to upgrade this agent to 13c.
Agent Host name: ora1-2 Agent Version: 12c Agent Host Flavor: OEL 6
Login to the EM 13c through the browser. On the summary page, click SETUP. Under this, select “Manage Cloud Control” and then the “Upgrade Agents” option.
Click on the Add option under the “Agents for upgrade” option to view the list of agents that can be upgraded to 13c.
Select the agent you desire to upgrade and click OK.
Review the information and click on Submit to upgrade the agent.
After the agent upgrade, review the status manually.

Agent upgrade installer creates a new directory called “agent_13.1.0.0.0” under the previous 12c agent directory.
