While executing initial logon process, I execute a concatenation clist multiple times for ISPPUSR, ISPTUSR, ISPSUSR, and ISPMUSR. The concatenation clist executes SYSDSN to determine if dataset is cataloged.
Prior to invoking ISPF, SYSDSN will fail on the third dataset with message, "ERROR PROCESSING REQUESTED DATASET". Will also fail on all subsequent datasets as well.
After ISPF has been establised, I can execute the series of concatenations and all four invocations will show SYSDSN returns OK

I have tried re-arranging the order of datasets and it still fails on the third invocation. I've tried various other dataset names - it still fails on the third time.

What conditions cause "error processing requested dataset" ?

  • An error parsing the DSN
  • An error in the dynamic allocation SVC
  • An error in OPEN processing

The second seems, IMPO, to be the most likely, although the third can't be ruled out. If you can browse the syslog, it may have additional information.
