Improve NQR Performance

When doing an NQR on Nodes with tens of millions of files, the initial TSM database search and sort operation which takes place on the server takes several hours.
We noticed that the hardware resource utliziation (CPU, DB2 Disks) is not very high during this procedure.

DB2 uses 60% of a single core
dsmserv uses 50% of a single core

DB2 DB Disks are utlized 25%
DB2 Logs are utlized max 15%

Seems that this process runs single threaded and not very well optimized.

However having a good RTO perspective when using TSM also on large Nodes is crucial if TSM should succeed in the future.

Telling users: "Well now we have to wait 1 day until TSM is ready and begins to send back your data" is no option and Nodes with several tens or even hundreds of millions of files is not that uncommon even today.

    IBM has evaluated the request, and has determined that it can not be implemented at this time or does not align with the current multi-year strategy. This request may be resubmitted for consideration after 18 months from the date of submission. The request submitter will automatically be notified by email when the request qualifies for reconsideration and resubmission.

    Consider usingFlashCopy Manager to protect systems with huge numbers of files.
