Advanced Image Copy Services support

Advanced Image Copy Services of IMS HP Image Copy allows you to take advantages of point-in-time copy functions (Concurrent Copy, FlashCopy®, and SnapShot) of DFSMSdss Advanced Copy Services to produce image copies faster and reduce unavailability time for IMS databases.

Advanced Image Copy Services uses the DFSMSdss cross-memory application programming interface (API), ADRXMAIA to process DFSMSdss DUMP and COPY commands.

When IMS database data sets reside on EMC DASD, IMS HP Image Copy can use the EMC API to invoke TimeFinder/Clone to copy the data sets instead of using FlashCopy or SnapShot of DFSMSdss.

IMS HP Image Copy supports three options for Advanced Image Copy Services: COPY, FDUMP, and DUMP. You can request this feature by specifying the FASTIC keyword in the ICEIN control statement. For more information about copy methods and processes of Advanced Image Copy Services, see Advanced Image Copy Services.

Restriction: The DUMP option does not support the following types of database data sets:
  • Encrypted database data sets
  • Extended format data sets
