Adding a new DEDB Data Capture exit routine using online change

You can add a new Data Capture exit routine to a DEDB by using the online change function.

To add a new Data Capture exit routine, follow the procedure below:

Procedure

  1. Assemble and link edit the new exit routine into the IMS.SDFSRESL or one of the libraries in the IMS.SDFSRESL STEPLIB concatenation.
  2. Run a DBDGEN for the DEDB with the new exit routine designated in the DBD or SEGM parameter: "EXIT=".
  3. ACBGEN is also needed to build the application control blocks to implement the DEDB definition that includes the new exit routine. The changed or new application control blocks must be built into the active IMS system's staging copy of ACBLIB, which is offline.
  4. Run the Online Change Copy utility, DFSUOCU0, to move the changed ACBLIB from the staging ACBLIB to the inactive (A or B) copy of the ACBLIB that is online to the active IMS system.
  5. Enter the normal /DBR command sequence to remove access to the DEDB from the active IMS system.
  6. Enter and follow the online change command sequence for PREPARE processing for ACBLIB changes.
  7. Enter and follow the online change command sequence for COMMIT/ABORT processing for ACBLIB changes. The online IMS system will switch from using the active (A or B) copy of the ACBLIB to the inactive (A or B) copy.
  8. Enter the normal /START DATABASE and /START AREA commands to make the DEDB and its areas accessible to the active IMS system.
