Symptoms:

When doing a REORG line command on a tablespace or index, space calculations seem to default to (4,20).

Resolution:

The space calculation used in the highlevel.CDBAMDL member MJUTLRO is based on the RUNSTATS value in NACTIVEF for tablespaces and N.LEAF for indexes. If this value is -1 in SYSIBM.SYSTABLESPACE or SYSIBM.SYSINDEXES in either of the above mentioned columns for those objects, then CA takes a PRIQTY default value of 4, this indicates that no runstats have been run.

The datasets that this applies to are:

000010 //SYSUT1   DD  UNIT=SYSDA,DISP=(,PASS),
000011 //             SPACE=(CYL,(4,20))
000012 //SORTOUT  DD  UNIT=SYSDA,DISP=(,PASS),
000013 //             SPACE=(CYL,(4,20))

Note: the RC/Query profile parameter CA-UTILITIES ==> N (Y/N) is set to N. This is a IBM REORG not a CA RAPID REORG! These two utilities utilize different highlevel.MODEL JCL.
