Programming requirements

The application programs that invoke Advanced Copy Services functions must meet with the following minimum requirements:

For Global Mirror for System z®, Metro Mirror for ESS, Global Copy for ESS, and Metro/Global Copy for ESS requests, the ANTAS000 address space must be active at the time the SDM API is invoked. For Snapshot, FlashCopy, Global Mirror for ESS, and Metro/Global Mirror for ESS requests, the ANTMAIN address space must be active at the time the SDM API is invoked.

The SDM API does not provide any data management services, such as allocation or cataloging of data sets. To copy data sets where these services are needed (such as accessing data sets on target devices), use a data set copy program such as DFSMSdss.
