MERGE CLOG: Merge Nucleus Cluster Command Logs

In an Adabas cluster environment, you can merge command logs (CLOGs) across a cluster in one of two ways:

  • If your system is set up appropriately (CLOGMRG=YES and user exit 2), CLOGs are merged automatically.

  • Otherwise, you can merge CLOGs manually using the ADARES MERGE CLOG utility function.

Sequential data sets are expected as input to the MERGE CLOG function; therefore, the ADARES CLCOPY function must be executed prior to the ADARES MERGE function.

Essential Parameter

NUMLOG: Number of Command Log Data Sets

The NUMLOG parameter is required: it specifies the number of command log data sets to be included in the merge process. The maximum number is 32.
