You could write a rexx exec to do this, and then execute it in batch via your
job scheduler, or via automation that runs at system shutdown. I am not aware
of anything canned to do this.
If you would consider moving the data back into a unix filesystem then I can
suggest you create a temp filesystem(TYPE(TFS)) which is a memory only
filesystem. Every IPL the filesystem is gone. On our systems /tmp is thrown
away with every IPL.
MOUNT FILESYSTEM('/&HFSSYS./TMP')
MOUNTPOINT('/tmp')
TYPE(TFS) MODE(RDWR) PARM('-s 256')
UNMOUNT

Subject: USS commands to clear log
Hello,
We have a mainframe system running z/OS R1.13.
We have the following USS file mounted to a MVS data set
\tmp\daemon.log.b
This file has grown very large over time, as it is not being cleared out on a
regular basis.
What commands can we issue during a shutdown of our z/OS system that would do
the following:
- clear all but the previous 30 days data
- clear all data
If possible, we want to clear this USS file out when z/OS is being shut down,
so that it will be clean during the next IPL.
We do not want to effect the USS file permissions nor the MVS data set.
Any suggestions would be appreciated.
