PDSE diagnostic aids

The following diagnostic aids are provided for PDSE:
  • A restartable SMSPDSE1 address space to eliminate the need to re-IPL because of PDSE hang conditions.
  • Operator commands to help diagnose PDSE errors
  • IPCS VERBEXIT SMSXDATA dump formatting
  • A sample entry in the logrec data set for a PDSE problem
  • Return codes that are common to all PDSE modules
  • Reason codes that are common to all PDSE modules
  • A component trace facility that can be used to diagnose PDSE problems. This component trace facility should be used only at the request of IBM® Support, in which case procedures for using the trace will be provided by IBM Support.
Exception: PDSE does not issue messages. Messages issued when processing a PDSE are from the PDSE access method, or they are PDS compatible messages from the SAM interface modules.
