Rao, I didnt follow this thread from the beginnig, but if you primary task
is to release disk space, try
echo > alert.log (or cat /dev/null > listener.log) instead of rm.

Terry,

I tested this again now.  I removed alert.log and then checked disk usage.
It did not release the disk space.  Then I bounced the db.  Now, the disk
space is released.

Environment: Solaris 7, 64 bit. Oracle 817.

On Solaris 2.5, 2.6 and 2.7, as well as AIX we have removed the alert.log
and
space has immediately become free.  (Not true with the listener.log
however).
