Virtual Memory Requirements in the CICS Address Space

Portions of both the transaction dump capture component and the region dump capture component run in the CICS address space.

The virtual storage requirements in the CICS address space are shown in the following table.

Region dump interface program storage

Region dump interface working storage, change summary data

350KB 

Note

  1. This storage is above the 16MB line.
  2. This storage is calculated based on the value set for the ABLIMIT transaction dump global option. The estimates listed here are per ABLIMIT value. Multiply the estimates by the value you specify for ABLIMIT (the default value is 5). Note that the total amount of storage is obtained when the Abend-AID transaction dump interface initializes in the CICS region, and is freed when Abend-AID terminates in the CICS region.
  3. The component is optional.
