The ERO initialization parameters PTHRESH, PMXTAPES, and PMXYEARS control which tapes are consolidated by SARPAC. This table provides a description of each of these parameters:
Lets you specify a threshold value.
For example, only consolidate tapes that are 55 percent unused.
Lets you limit the SARPAC run by specifying the number of tapes that will be processed.
Lets you specify how long a tape can exist before it is automatically consolidated, an important function because tapes tend to have I/O problems as they age.
You can use the SYSIN statements to specify which tapes to use for input. Additionally, you can modify the SARPACUX user exit to select input tapes based on user-defined criteria.
SARPAC mounts its input tapes directly. SARPAC does not use the expanded access server for tape and robotics to mount input tapes.
