Dumps produced by DBCTL

The formatted dump feature of IMS is available with DBCTL. This feature formats the system, database, and data communication areas of IMS. It formats the control blocks and data areas in an IMS region.

See Diagnosis in IMS product documentation for guidance information on the areas that are dumped.

Control blocks generated by DBCTL have an eyecatcher for visual identification. For example:
  • **SCD : system contents directory area
  • **SSA : SAP and save area
  • **DSP : dispatcher area.

The recovery token is included in dumps produced by DBCTL. Output is to the IMS log.
