IMS Version 12 Upgrade issue


After IMS version 12 upgrade from version 10, Version 10 BMC Image copy became incompatible with IBM IMS recovery. However, BMC recovery works fine.



Reason:

As per IBM IMS standard the first byte of Imagecopy dataset should be as follows.

‘05’ – Version 9

‘06’- Version 10

‘07’ – Version 11

‘08’ – Version 12

IMS version 10, Image copy taken by IBM IMS image copy uses ’06’ as first byte whereas BMC Image copy uses ‘05’ as the first byte.  IBM version 12 Recovery is compatible only with version 11 and Version10.  So IBM recovery failed to recover from BMC version 10 Image copy as it had wrong header value of ‘05’ instead of ‘06’.

Work Around: BMC recovery version 4.5 that runs on IMS V12 is compatible with its BMC Image copy of version 10

Fix:

PTF named BPQ6812 (by BMC support) which will fix our invalid BMC Image copy header issue.
