Oracle Database: Start EM console for multiple instances on the same server

Today I had to manually start Enterprise Manager console for an instance running on a server which has already other instances running.

The command to start EM Console is:

emctl start dbconsole

full path of the command is:

/u01/app/oracle/product/11.2.0/db_1/bin/emctl start dbconsole


This start EM for instance referred in ORACLE_SID variable.

In case of multiple instances running on same server you can start EM console by assigning ORACLE_SID variable according to the EM you need to start.

For example if we need to start EM console for "TEST1" instance we set ORACLE_SID:

[oracle@orcl ~]# ORACLE_SID=TEST1

[oracle@orcl ~]# emctl start dbconsole

Same thing if we need to start EM for "TEST2" instance:


[oracle@orcl ~]# ORACLE_SID=TEST2

[oracle@orcl ~]# emctl start dbconsole
