Method 1 : Using OAM (Oracle Application Manager)

Login to the E-Business Home Page -> System Administrator -> Concurrent : Manager/ Administer

Because 1 process is running that means the ICM is running. In this Form we can see if the other Concurrent Managers (CM) are running as well.

METHOD 2 :  OS level (on UNIX)

ps -ef | grep FNDLIBR 

ICM is not running

[oracle@APPS VIS_apps]$ ps -ef | grep FNDLIBR
oracle 17846 7256 0 01:20 pts/2 00:00:00 grep FNDLIBR
[oracle@APPS VIS_apps]$
