Description:
The Web and GUI are both not working. When we try to do "dlib" or "util", nothing happens. (There is no error message, but it doesn't do anything.)

We tried rebooting. We can do "dlib" and "util" now but Oracle didn't come up. We see the following in the alert_log:

When we try to start Oracle with util o, we get:

Resolution:
Our staff analyzed this as follows:

The oracle archive filesystem was unmounted.

We can’t see an Oracle hot backup from Jan 13, I only see one from Jan 16 with the size of 10GB:
sunfire-a16(1) >>pwd
/backup
sunfire-a16(1) >>ls -lrt

In any case, Oracle hot backup size can be changed in case you had some special indexes job that created lots of archives files, this process backup do backups the datafiles and the archives files.

Customer reply:
Because the backup was taking up more than two-thirds of the /backup partition space--following its copy to an external drive, located at /storage/backup--we deleted it. You will find the 44G file in the directory /storage/backup. Please refer to the incident mentioned in the opening entry; it was placed on Monday and will probably be related.

I ran the hot backup procedure again last night and it is back to its more usual size of 10G.

--------------------------------------------------------------------------------

It may be that the some job created lots of archive files that caused the backup to be big. I think we can ignore this backup now that the size for the next backup came back to its normal size.
