APAR Error Description / Circumvention

-------------------------------------------------
System job QDBXyyyXR2 (where yyy is an iASP) may encounter a
msgMCH2804 f/IxMachineIndexExtend t/QDBPUTM.

CORRECTION FOR APAR 'SE72707' :
-------------------------------
The cross reference file index size limit was reached which
caused the msgMCH2804. RCLSTG SELECT(*DBXREF) must be run to
change the index size to *MAX1TB.  This ptf enhances cross
reference file verification to ensure that if an index must be
recreated, it is always recreated with a size of *MAX1TB.

The operating system includes alerts for indexes that are
reaching their maximum size. SQL message SQL7062 for limit id
15400 is sent to QSYSOPR when any index (including cross
reference) exceeds 90% of the maximum allowable size.  If this
message is sent for a cross reference index (named QADBnnnnnn in
QSYS or QSYSnnnnnn), a plan should be put in place to run RCLSTG
SELECT(*DBXREF) to modify the cross reference indexes to a size
of *MAX1TB.  RCLSTG SELECT(*DBXREF) requires restricted state.
