Issue/Introduction



When running TMSPTRS we are getting a large amount of invalid ERR24 messages at the end of the free DSNB chain.  Why?

Environment

CA 1 12.6 or 14.0

Resolution

If the SYSUT3 DD allocation in the TMSPTRS JCL does not meet these requirements you can get invalid errors.

1.  The allocation must be as large as your TMC.

2.  It must be on one volume.

3.  If you need more than 10,000 CYL you must use the DSNTYPE=LARGE specification in the JCL.

We copy the TMC to the SYSUT3 before doing the processing of the pointers and if we cannot get a complete copy then you may see invalid ERR24 messages.
