HPCADIAG

The diagnostic file is created when the HPCADIAG DD is allocated. This file is defined with RECFM=VB and LRECL=1024.

The diagnostic file captures a snapshot of IMS HP Change Accumulation Utility processing that includes significant inputs, outputs, intermediate tables, and status. Diagnostics are available in all environments:

• HPCAMAIN
• HPCABAT0
• HPCAE000

The diagnostic file can always be produced. However, this file is intended for use by support personnel in troubleshooting IMS HP Change Accumulation Utility failures.

The file can be very large and the processing necessary to capture the information can have a negative affect on performance. Normally, it is not expected that diagnostics will be captured from production runs of IMS HP Change Accumulation Utility.
