Using rule sets
You must use rule sets to customize your batch journaling environment. You tell RUV about the recovery requirements of your VSAM files, and you specify the jobs and programs to which those requirements apply. RUV requires more information, such as where to store recovery information, how to build backout JCL, and when to run recovery jobs. You use rule sets to provide this information.
RUV provides rule set samples during installation and provides forms to help you organize rules for VSAM sets, job sets, and journal models.
RUV supports the following levels of rule sets:
- Subsystem level
- Job level
RUV uses the subsystem level rule set to examine all jobs that are running in the z/OS system. A job level rule set applies to a single batch job only; it does not affect other jobs. RUV searches a job level rule set ahead of a subsystem level rule set. This convention makes testing of rule sets easier and simplifies customization of rule sets for specific tasks.
