I knew you weren't crazy, Rachel. :)

So far this "feature" hasn't worked for me.  I have been moving
the alert.log and let Oracle create a new one since 8.0.5 and now
on 8.1.7 when I was unware of this "feature".  Now that I read about
it I am troubled.  Oh I am on Solaris 7 and 8 BTW.

Hmmm...  I am pondering whether I should modify my script or not.

Okay folks, I *knew* I wasn't crazy!  thanks to Anita for finding the post 
that Bruce sent to the list, that had the metalink doc in it

There was also a bug filed on it (which was closed as "not a bug") bug# 
1388186

It was filed for Solaris so this might just mean that the "feature" is 
Solaris specific, since people here are saying that they haven't seen it on 
other platforms.

We are on Solaris, but our scripts are written such that we don't rename the 
alert log so I haven't been able to prove it one way or another.

Problem Description
-------------------

The Oracle background processes has an open file descriptor on the 
alert.log.
When the database is up and running it continually holds this file 
descriptor open. This was not the case in 7.3.4, but is true for 8.0.5 to 
8.1.7.

This poses the question: What if the database is up and the alert.log
gets too large. Do I have to shutdown the database to release the open file 
descriptor on the alert.log, then deal with the large alert.log?


Solution Description
--------------------

You are able to copy the alert.log while the database is up and running.

1) Create an empty file:
       (example: touch nullfile.log)

2) Replace the old alert.log with the new empty file:
       (example: mv nullfile.log alert<sid>.log)

The running database experiences no affects when doing this.


Explanation
-----------

Having the continual open file descriptor on the alert.log is intended 
behaviour for the database.
