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
