Removing old records from the stats file
Periodically, you should remove old records from the stats file to ensure that the file does not become too large.
About this task
To perform this task, edit the sample job that Tape Optimizer supplies in the GTOSTREO member of the runtime_HLQ.CNTL library (where runtime_HLQ is the high-level qualifier that you specified during customization). In the JCL, specify a date in the format YYYY/DDD. Then run the job.
This job deletes any records for tapes that were copied before the specified date and that have already been scratched and reused.
