Re: QDBSRVxx Job Hogging the CPU

["Simon Coulter" <shc@xxxxxxxxxxxxxxxxx>]

Have you considered saving the access paths to reduce the CPU used during the 
restore?
If you save the access paths the indices will generally not need to be rebuilt. 
 There are certain 
situations where the access paths will be rebuilt even if they were saved 
e.g.,the logical has 
MAINT(*REBLD) specified, or when the logical files are in different libraries 
from the based-on 
physical files.  The Backup and Recovery Guide has more information on the 
specifics.

You can also use the EDTRBDAP (Edit Rebuild Access Path) command to manage 
access path builds.

Regards,
Simon Coulter.
