ECBRM/ECB Owner Collection - add retention to FS files

The ZECBM COLLECT and ZMOWN COLLECT commands are designed to provide flexibility so that users can put the output files in any directory that they choose. It does not make sense to add support to these commands to automatically clean up old files because the old files could be anywhere. Even if there are other customers who also want to restrict where output files are put, the directory name may be different. Therefore, ZECBM COLLECT and ZMOWN will not be updated to automatically remove old output files.

However, the lab recognizes the concern that old files need to be cleaned up. Because you are requiring your users to put the output files in a standard directory, there is a ZFILE command that could be added to the ZSTIM tables to clean up files older than a specified number of days. For example, the following command will remove any files in directory /etc/tpf-ecbrm that have existed for 2 or more days:
==> ZFILE find /etc/tpf-ecbrm/* -mtime +2 -exec rm {} \;

Please note that this command will also remove any files older than 2 days in a sub directory under /etc/tpf-ecbrm.

You could add the ZFILE command to the ZSTIM table to remove all files that are 2 days and/or 3 days old and/or 4 days old by doing the following commands:
==> ZSTIM A FREQ=DAILY,TIME=0015,MSG='ZFILE find /etc/tpf-ecbrm/* -mtime 2 -exec rm {} \;'
==> ZSTIM A FREQ=DAILY,TIME=0015,MSG='ZFILE find /etc/tpf-ecbrm/* -mtime 3 -exec rm {} \;'
==> ZSTIM A FREQ=DAILY,TIME=0015,MSG='ZFILE find /etc/tpf-ecbrm/* -mtime 4 -exec rm {} \;'

If you do this ZFILE command on the /etc/tpf-owner directory, it may remove the configuration file that is used by the ZMOWN support (/etc/tpf-owner/cfg.owner.csv). You would need to either recreate the configuration file or refresh the configuration file before doing the ZFILE to remove old files.
