Subj:   Transient Journal
 
From:   Hassinger, Bill

I have a couple questions concerning the transient journal:

** 1. I have noticed that in our environment when the transient journal is involved in a query, there is a significant slowdown of other sessions. The majority of CPU seems to be involved in the TJ session, even when all users have the same priority.

I understand that a rollback involves a RUSH priority. Does the Update / Delete also get higher priority automatically?

** 2. If a delete statement has a semicolon on the line following the statement, then another maintenance statement, are both part of one transaction?

        Delete from TableX
        ;
        Update TableY
        ;
        Select * from;

Are the delete and update rows kept in the TJ until after the select as part of one transaction?
