RE: shutdown hang

Hi Alex,
These are a set of 4 classes that are offered by Oracle and they are 4 separate seminars. These are for Oracle 8

http://education.oracle.com/seminars/track3.html http://education.oracle.com/new_desc/65320.html

The first 2 are 1 day and the backup and recovery is 1.5 days and the optimizer is 1 day. They are $600 per seminar.

I just noticed today they are offering the dumps and crashes seminar(65338) and the Data Mgt and storage internals (65339) and the Optimizer (65340) are being offered for Oracle 8i.

Its a real good class to go if you are interested in Internals and Scott Gossett is one of the best teachers, I think.

Hope this helps.
