Oracle EM 11g/12c database migration

1. Overview
The Oracle EM11g database needs to be migrated. The main steps are as follows:

1. Disable OMS

2. Back up the current database and restore it to the new server.

3. Update OracleEM OMS database connection Configuration

4. Start OMS

This operation method is also valid in Oracle EM 12c.

2. Procedure
Step 1: Disable OMS

Find the emctl tool in the bin where OMS is located and disable the OMS service.

Step 2: Use RMAN to back up and restore data. It is very simple and will not be explained.

Step 3: update the configuration of Oracle em oms database connection

First, check the database connection configuration details.

You can use the emctl tool to modify the database configuration of em grid control. emctl provides two modification methods.

Emctl config oms-store_repos_details (-repos_host

Connect descriptor shoshould be enclosed in quotes. eg: '"<conn_descr>"' or "'<conn_descr> '"

The specific command is as follows:

Emctl config oms-store_repos_details-repos_conndesc "'(DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP) (HOST = 192.168.65.8) (PORT = 6688 ))) (CONNECT_DATA = (SID = emrep) '"-repos_user sysman-repos_pwd welcome2012

 

Emctl config oms-store_repos_details-repos_host 192.168.65.8-repos_port 6688-repos_sid emrep-repos_user SYSMAN-repos_pwd welcome2012

 

Finally, modify one of the two commands.

/U01/app/oracle/middlehome/oms11g/bin @ lin-65-210-dba => emgrid $ emctlconfig oms-store_repos_details-repos_conndesc "'(DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP) (HOST = 192.168.65.8) (PORT = 6688) (CONNECT_DATA = (SID = emrep) '"-repos_user sysman-repos_pwd welcome2012
