Oh...I forgot the mention that skulker is in /samples, and not marked as
executable so I wrote a SMPE usermod that copies it from there to /usr/sbin.
Here is the source to build that usermod to then be applied if you are
interested (or anyone else)

Gadi,
If you are running low on space, you might also look at running the skulker
shell script that IBM supplies. I have a minimally configured CRON schedule
that runs a few housekeeping scripts. We also converted /tmp from a TFS to a
real filesystem a couple years ago.
First is to touch certain files created at IPL that never get their last used
date/time updated, but if they disappear cause a problem.
!/bin/sh
filetouch
resets last access date/time on in process files in /tmp so that
skulker does not delete them for inactivity.
touch -c /tmp/dpi_socket
touch -c /tmp/omproute.stderr
touch -c /tmp/omproute.stdout
touch -c /tmp/pagent.pid
touch -c /tmp/pagent.log
touch -c /tmp/pagent.log1
touch -c /tmp/pagent.log2
touch -c /tmp/sshd.stderr
touch -c /tmp/unix.str
touch -c /tmp/CAZLCS01
touch -c /tmp/EQACMINT
touch -c /tmp/FMNCAS-IPVCERT.kdb
touch -c /tmp/FMNCSEP
touch -c /tmp/IDIGMAIN
touch -c /tmp/IPVVRFY
Then I run via CRON
00 0 1 * * mv /var/spool/cron/skulker.log /var/spool/cron/skulker.log.old
01 0 * * * /shared/etc/filetouch
10 0 * * * /usr/sbin/skulker -R -l /var/spool/cron/skulker.log /tmp/ 3

Hi,
Is it possible to extend the /tmp file system without an IPL?
It's currently defined as:
MOUNT FILESYSTEM('/tmp')
MOUNTPOINT('/tmp')
TYPE(TFS)
MODE(RDWR)
PARM('-s 100')
We are running z/OS v2.2
Thanks
Gadi
