Managing dump files

Use this procedure to manage dumps that are captured for the z/TPF debugger by using the ZDDMP command.

About this task

With the ZDDMP command, you can take the following actions to manage dumps:

  • Change the dump retention period for dump files that are kept on the file system.
  • Import a dump file that was captured on a different z/TPF system for viewing.
  • Synchronize the dump control records with the dump files that are present on the file system.
  • Remove dump files that are expired from the file system by forcing the policing routine to run and remove any expired dump files. A policing ECB is created every 30 minutes to scan for expired dump files.
  • View details of a stored dump from your z/TPF console.

Procedure

Enter one of the following commands to manage your dumps:

  • Enter ZDDMP IMPORT Source-sourcename, where sourcename is the name of the dump file to be added to the dump control records.
  • Enter ZDDMP ALT RET-time, where time is the retention period, to retain dump files.
  • Enter ZDDMP SYNC ALL to synchronize all dump control records with the dump files that are present on the file system.
  • Enter ZDDMP SYNC PROC-procid, where procid is the processor ID, to synchronize dump control records on a specific processor.
  • Enter ZDDMP CLEAN to remove dump files that are expired.
  • Enter ZDDMP DISPLAY to view details of a stored dump from your z/TPF console.
