Providing a DOPT ACBLIB data set

You must provide a DOPT ACBLIB data set into which ZDT/IMS can dynamically build PSBs.

You use the DYNACB parameter on the HFM1POPI macro statement to specify the DOPT ACBLIB data set. You must concatenate the specified data set after the primary ACBLIB data set in the IMS™ execution JCL (that is, the JCL that starts the IMS control region).
