This command is primarily designed to provide detailed information
about a particular catalog request. Use this command to obtain more
information about a request that showed excessive processing time
after the MODIFY CATALOG,LIST command was issued. Much of this information
is designed for IBM® Service
personnel, but there are some fields that can help you do real-time
problem diagnosis:
- CCASRCH - the last name of an entry that is attempting to be accessed (or was accessed) in the catalog the request is oriented to.
- Oriented to - shows the catalog that is being accessed for the indicated request
- Waiting for completion of - indicates a specific event outside of the catalog code that the request is waiting for. This includes the address where catalog code will continue executing when the request is complete, and the length of time the request has been waiting
This information might allow you to perform other real-time diagnosis depending on what the request is waiting on, and what catalog or data set is indicated. For example, if it shows it is waiting on the completion of a BCS ENQ, you might try issuing a D GRS,C command to see if there is contention on that catalog name, and what job in the system might be causing that contention.
There is other information that might or might not be displayed in response to this command, depending on the type and state of a request. The above example does not show all of this information.
