Incremental Image Copy function
This topic shows example JCL using the Change Accumulation utility with the Incremental Image Copy function.
The Concurrent Pointer Checking feature is also invoked. One change accumulation group is processed. Incremental Image Copy is executed for one database within the group.
The input log data set, the input and output change accumulation data sets, and the input and output image copy data sets are dynamically allocated. The Change Accumulation utility allocates devices only when necessary to minimize resource usage. The change records used to update the image copy are also written to the change accumulation data set.
