1. What is a Concurrent Manager ?

 

A Concurrent Manager is a background process which manages the concurrent requests in Oracle Apps 11i. 

2. How many type of Concurrent Managers there are in Oracle Applications 11i ?

  • Internal Concurrent Manager (ICM): a background process which manages (start/ stop) the other managers. The ICM must run in order to start/ stop the other managers, so to process concurrent requests. 

  • Standard Manager (SM): is the default concurrent manager. If a request is not defined to be run by a particular concurrent manager (Inventory Manager, Receivables Tax Manager, etc) the SM will take care of the concurrent request. 

  • Conflict Resolution Manager (CRM): is handling any conflicts that might occur within the concurrent requests (for instance, 2 concurrent requests don't have to run in the same time on Monday between 1-2 Pm ). This task could be done by ICM as well. 

 


3. How could I know if the ICM is started or not ?

 

A) Using the OAM:

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

Concurrent Managers in Oracle Apps

 

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. 

 

 

B) At the 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]$

ICM is running:

[oracle@APPS VIS_apps]$ ps -ef | grep FNDLIBR
oracle 18069 18064 0 01:22 pts/2 00:00:00 FNDLIBR 
oracle 18297 18137 0 01:22 ? 00:00:00 FNDLIBR 
oracle 18298 18137 0 01:22 ? 00:00:00 FNDLIBR 
oracle 18299 18137 0 01:22 ? 00:00:00 FNDLIBR 
oracle 18303 18137 0 01:22 ? 00:00:00 FNDLIBR 
oracle 18304 18137 0 01:22 ? 00:00:00 FNDLIBR 
oracle 18623 7256 0 01:23 pts/2 00:00:00 grep FNDLIBR

 

4. How could I start/ stop the ICM ?

 

cd <COMMON_TOP>/admin/scripts/<SID>_<localhost_name>

[oracle@APPS VIS_apps]$ adcmctl.sh start apps/apps

or 

[oracle@APPS VIS_apps]$ adcmctl.sh stop apps/apps

 

 

5. Where is the location of the ICM log file ?

 

If the environment variable APPLCSF is set, the ICM log file will be located in $APPLCSF/$APPLLOG. Otherwise, the ICM log will be located in $FND_TOP/$APPLLOG.

The log file name has the following format: <SID>_MMDD.mgr

 

The log file contains the following information:
