Re: QDBSRV jobs

Hello Carl,

These are database server system jobs which are responsible for rebuilding 
access paths.  Usually caused by 
doing a restore without having saved the access paths but there are other 
causes.

QDBSRV01 is an event handler and passes the work off to the other QDBSRVxx jobs.

QDBSRV01 runs at priority 9 (because it needs to get the event notification 
quickly), the others run at 
priority 52 to do the rebuild.  Under normal circumstances they shouldn't 
affect your system noticably 
(although they will use CPU) but occasionally the priority 9 job has a problem 
with lot's of events and locks 
and can kill the system.

You will find a small amount of documentation on all the system jobs in the 
Work Management Guide in Chapter 
13.

Regards,
Simon Coulter.
