Interpreting MODIFY CATALOG,LIST Output

The following is an example of the output for MODIFY CATALOG,LIST:

IEC347I LIST CATALOG TASK(S)
*CAS****************************************************************
* FLAGS -  TASK ADDRESS - JOBNAME  / STEPNAME - ELAPSED TIME - ID  *
* -W---L     005AB2A8     ACCTING  / SORTSTEP     00.08.26     04  *
********************************************************************
* O-OLDEST, W-WAIT, A-ABEND, E-ENQ, R-RECALL, L-RLS                *
*CAS****************************************************************

The job ACCNTING has been waiting for more than 8 minutes. This is excessive time for a catalog request, and indicates a problem. The "L" indicator shows that this request is currently waiting on a response from the RLS address space for some requested function.

You can also use the MODIFY CATALOG,LISTJ(ACCTING),DETAIL command to obtain a more detailed set of information about this particular catalog request. This information is useful to determine if it is waiting on a particular catalog that is unavailable, or an ENQ resource on which there is contention. The information from the LISTJ DETAIL command is useful when reporting a suspected problem to IBM® service. Using either the END or ABEND parameters and the task ID or address, you can stop the request. See Ending a Catalog Request Task for more information about ending CAS tasks.

The flags have the following meaning:

O: The task is the oldest active task. This is only indicated if all active CAS tasks are listed.
W: The task is waiting for the completion of some event, for example, an ENQ or a tape mount.
A: The task is abnormally ending.
E: The task is waiting for an ENQ on a catalog resource.
R: The task is suspended while the requester's address space is recalled to perform a needed function or obtain information. For example, mounting a volume, verifying security, renaming or erasing data, or extending a data set can cause a recall. If the recall lasts for a very long time, examine the system log for messages indicating the delay. This recall has no relationship to any DFSMShsm function.
L: The task is suspended waiting for a response from the RLS address space for a request for an RLS function. When this flag displays, you should follow the RLS-specific diagnostic procedures for gathering information to report this problem.

The TASK ADDRESS field gives the hexadecimal address of the CAS service task.

The JOBNAME / STEPNAME field gives the name of the job and step which initiated the catalog request.

The ELAPSED TIME field gives the "hours.minutes.seconds" that the task has been active in CAS.

The ID field gives the CAS identifier for the task.
