Hello DB2 Server for VM users with VMDSS enabled running in z/VM 5.30 and above:
VM APAR VM64775 has been opened to address the ARIYI19 09 abends encountered by
DB2/VM server running with VMDSS enabled under z/VM 5.30 and above.
ERROR DESCRIPTION:
An error in pageable PGMBK processing causes segments which may
contain changed pages to be skipped. This can lead to changed
pages not being saved which in turn can lead to DB2 data
corruption.
The PTFs are now available:
R530 UM32966
R540 UM32967
R610 UM32968
Note that this may happen in a particular workload and in a very heavily loaded
(paging rate up to hundred of thousands pages per second) VM system. So far,
only couple of customers had reported this kind of abends to
IBM. The abends can be avoided by changing the workload.
Please review DOC APAR PK73730 for more details.
Regards,
....Roland
