Hi All ,

I am working on a migration project -In which am asked to migrate a ZOS QM to x86 QM . For this I got a mqdump of the existing QM .

I came across a process like below ,
[code]
DEFINE PROCESS('MQPE') +
APPLTYPE(2) +
APPLICID('// JCLLIB ORDER=MSS.CNTL') +
USERDATA('//JS01 EXEC MQPE,QM=MQY1,Q='!'') +
REPLACE
[code]

I tried the same in x86 but its giving me error . Any idea how to fix this ?

This process is used in QLOCAL('SYSTEM.ADMIN.PERFM.EVENT') +


Thanks in advance

The APPICID AND USERDATA as you can see are all specific to zOS. You would need to change that queue to a remote queue sending the message to a zOS queue manager to process.

The other option, of course would be to create the equivalent process in x86 and trigger the queue accordingly to the x86 process.

Have fun

APPLTYPE value of 2 indicates MVS. MVS o/s implements a variety types of work (CICS, IMS, batch JCL/PROCs).

If your intention is to move the work accomplished on MVS to Windows/UNIX o/ss, then you will my need to construct the equivalent shell scripts, and port the application(s) from MVS to the destination o/s.

Or, will the work remain on MVS, but be driven from/by the midrange qmgr?

What precisely is the requirement? If you are not MVS trained, you will need to find someone who is.

Do you mean that when a message arrives on the SYSTEM.ADMIN.PERFM.EVENT queue, this application is triggered?

What application do you have available to process event messages in your x86 environment? You could trigger than one instead.

Learn what it is that the application described in the PROCESS object does, and ensure that your replacement application on the x86 environment can do the same.

Cheers,
Morag

In the migration, you will also encounter Storage Classes. These are not applicable to MQ on Windows or UNIX platforms, as all local queues share the same disk storage structure.

The Recovery Logging mechanism is also quite different, so you will need to consider Linear versus Circular, and the number and size of Primary log files and Secondary log files.

Not that Im aware of.

Do you have z/OS experience? Do you understand JCL (the z/OS batch scripting language)? What is your MQ skill level?

Id begin by exporting the z/OS qmgr object definitions, then importing them into your Windows qmgr, then resolve the errors you observe.

IBM products have error message ids that you can look up in the KC or downloadable .pdf manuals. z/OS MQ messages are in the form of CSQnnnnn. Midrange MQ messages are AMQnnnnn.
