Re: Diskeeper 5.0

From my past experience Oracle does not like to have Diskeeper running on drives that
the data files, or any other Oracle files on it for that matter. I was even advised by Oracle not to run it on the
drives that have data on them. I think the problem I was running into were strange locking problems,
and I/O contention. When you created your dbf files both data and indexes you already preallocate
the space anyway, so I was told there really was no reason to defrag them anyway. As far as I know
if you have a lot of table extents, Oracle only supports one way of fixing that, export-import.

Anyway, when I turned off Diskeeper, problems went away, and things got a lot better,
