Does anyone if it's safe to clear /tmp when the system is re-ipl'ed
and/or on a periodic basis?
IBM provides a QShell command named 'clrtmp' intended to clear this
directory. You can read about it in the Info Center:
IBM's statement is that "Unpredictable results may occur if clrtmp is
called while the sysstem is running." They suggest that you may want to
run it in your QSTRUPPGM (i.e. after an IPL, but before software is
Having said that.. in reality, /tmp is just a normal directory (unlike
the QTEMP library), and any application can use it as they see fit. It
might be smart to ask any of your software vendors whether or not
clearing /tmp will hurt their software. As much as I HOPE they're not
storing permanent/required data in that directory, there's little to
stop them from doing so.
