MQ Z/OS Page Sets with different hlq's

Postby ramesh01 » Tue May 15, 2018 3:51 am

Hi,
On MQ v7.1 Z/OS, we have 8 page sets with HLQ WEBMQ.QSNO The page sets are like WEBMQ.QSNO.PSID01, WEBMQ.QSNO.PSID02 ...WEBMQ.QSNO.PSID08. All these are non-SMS.
Is it possible to define page set 09 with different HLQ like WEBMQSMS.QSNO.PSID09. I do not see any documentation about pagesets with different HLQs. We need to use different HLQ as current HLQ is not supporting SMS datasets.

Thanks

From https://www.ibm.com/support/knowledgece ... -levelQu...
How to change the high-level qualifier (HLQ) for the page sets
This task gives information on how to change the HLQ for the page sets. To perform this task, do the following:

Define the new HLQ page sets.
If the size allocation is the same as the old page sets, copy the existing page set using REPRO to the empty new HLQ page sets. If you are increasing the size of the page sets, use the FORMAT function of CSQUTIL to format the destination page set. For more information, see Formatting page sets (FORMAT).
Use the COPYPAGE function of CSQUTIL to copy all the messages from the source page set to the destination page set. For more information, see Expanding a page set (COPYPAGE).
Change the CSQP00xx DD statement in the queue manager procedure to point to the new HLQ page sets.

Restart the queue manager and verify the changes to the page sets.
This implies you cannot have different HLQ for different page data sets, but does not definitively states it. You might want to try creating a different HLQ on your test system.
