Baseline data sets
If a full-recovery baseline is requested during Analysis, the worklist that creates the baseline generates one or more data sets to contain the unloaded data.
The -UNRC worklist command sores the data set names in the baseline tables, and the -JCLP worklist command recovers these names. When XML or LOB data is included in a full-recovery baseline, the CM_UNLOADDSN product table includes a SOURCETYPE column to indicate whether the unload utility generated a file reference data set.
The Execution diagnostic output file identifies the data sets that are specific to the baseline and those that are permanent work data sets. The data sets that are needed for full-recovery baselines have the DDName BLRPnnnn. If the full-recovery baseline also includes XML or LOB data, file reference data sets are needed. The baseline data sets that Execution generates should be retained as long as needed to allow for baseline recovery. In contrast, you can delete the permanent work data sets after Execution completes successfully. You can generate a JCL job step that automatically deletes the permanent work data sets.
