Scripts to help with the concurrent manager

The concurrent manager is the job-scheduling component of Oracle Apps:

The following SQL scripts located under $FND_TOP/sql are useful when diagnosing concurrent manager problems:

1. afimchk.sql Tells the status of the ICM and PMON method

2. afcmstat.sql Lists active manager processes

3. afrqrun.sql Lists all the running, waiting and terminating requests

4. afrqwait.sql Lists requests that are constrained and waiting for the ICM to release them

5. afrqscm.sql Prints log file name of managers that can run a given request. It can be used to check for possible errors when a request stays in pending status. It requires a request id value.

6. afcmcreq.sql Prints the log file name of the manager that processed the request

7. afrqstat.sql Summary of completed concurrent requests grouped by completion status and execution type. It requires number of days prior to today on which to report parameter.

8. afimlock.sql Lists locks that the ICM is waiting to get

9. afcmrrq.sql Lists managers that currently are running a request


Techniques for checking the status of the concurrent manager:

1. Log in to applications as System Administrator responsibility and navigate to the concurrent manager administration page (Concurrent, Manager, Administrator) and under the processes column if the target and actual column equal the same number (above 0) this means the managers are up and running.

2. You can also go into SQL*PLUS as APPS and run the following script:

SQL> @$FND_TOP/sql/afimchk.sql

This script will return output similar to the below:

Status Since Method
-------------------------------------- --------- ----------- ------
Internal Conc Manager is running on - colapp03 05-MAR-99 06:41:32 PM LOCK

Also, this on bouncing (stopping and re-starting) the concurrent manager.

As an practice, u should stop ur concurrent manager service through adcmctl lying under $APPLCSF/scripts/host_sid

whenever there's a need to shutdown n then startup ur database.

As there could be a scenario that ur ICM wont work.
