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).
