Multiple subsystem consideration for BMC AMI Data Optimizer
BMC AMI Data Optimizer uses a SYSTEMS-level ENQ with a QNAME of DAPOPEN to ensure that data is not being written to and read from a data set simultaneously.
For this feature to work correctly when you are using products such as GRS from IBM or CA MIM from CA Technologies to manage your systems, ensure that the DAPOPEN ENQ is propagated to all of your systems that will execute Data Optimizer.
