Hi
I am trying to use CORREL-ID in my MQ series MQPUT application, so that I can select a particular message to be retrieved from the queue later using MQGET.
I appreciate if you could let me know what options I need to use to make this possible.
Currently I used MQCI-NONE to MQMD-CORRELID.
Thanks |

You need to add MQMO_MATCH_CORREL_ID in the matchoptions attribute.
Cheers.

Thanks a lot for the reply.
But here I am not able to generate the CORREL-ID from the MQPUT call. When I see the CORREL-ID after a MQPUT call , it is zeros for all the messages.
I am working on OS390 using COBOL.
Thanks |

What are your put options. Can you post your code here.
Try this... In the put app itself, after the put is completed, print the correlid.
Is your put and get apps diff???
Cheers

Below is my code for MQPUT.
Both MQPUT and MQGET are different applications.
I printed the Correl-id and saw ZEROS in all.
Do I need to use any options to get QMGR generate the correl-id everytime it puts a mesg in the Queue........?
If yes ... I am missing that option, I guess..........
---------------------------------------------------------------------------
MOVE MQMI-NONE TO MQMD-MSGID.
**These two are commented*******************
MOVE MQCI-NONE TO MQMD-CORRELID.
MOVE MQCI-NEW-SESSION TO MQMD-CORRELID.
*******************************************
MOVE TRANS-FIELDS TO WS-OUTPUT-BUFFER.
COMPUTE MQPMO-OPTIONS = MQPMO-NO-SYNCPOINT +
MQPMO-FAIL-IF-QUIESCING.
MOVE MQMT-REPLY TO MQMD-MSGTYPE.
MOVE MQFMT-STRING TO MQMD-FORMAT.
CALL 'MQPUT' USING CON-HANDLE
OPO-Q-HANDLE
MQMD
MQPMO
OUTPUT-BUFFER-LENGTH
WS-OUTPUT-BUFFER
COMP-CODE
REASON-CODE.
-----------------------------------------------------------------------------

So you are missing MQPMO_NEW_CORREL_ID, from your pmo options. This would allow the QM to generate a unique correl id for you. If you wish you could as well pass one yourself "hardcoding" within your put app. At that time you dont need to set the above option.
Cheers.

Thanks. I tried this option just now. But it gave the below error.
"MQPMO-NEW-CORREL-ID" WAS NOT DEFINED AS A DATA-NAME.
I didn't find this option in any of my MQ copy books used below.(CMQgmoV,CMQmdV,CMQodV,CMQpmoV,CMQV)
Could you please explain me where can I find this.........?
Thanks |

The definition is there in CMQV copy book.
What version of MQ are you using???
Do you have the latest copy books.
10 MQPMO-NEW-CORREL-ID PIC S9(9) BINARY VALUE 128.
What platform???
Cheers.
Kumar

For the time being why dont you just initialize the correl id in your program while you figure out why the definition is not in your copy books.
Abstract from the family manuals.
"This option is supported in the following environments: AIX, HP-UX, OS/2, AS/400, Sun Solaris, Windows NT, plus MQSeries clients connected to these systems. "
Which means probably it is not available on OS/390.
Check with your ibm rep for more info.
But the other alternative which i suggested should serve your purpose.
Cheers.

Thanks. I am in the process of checking with MQ admin/IBM rep to make sure are my copy books are from latest version or not............
And I was able to put messages by hardcoding the values in MQPUT call.
Now my next problem is ............
I have 8 messages in the below CID sequence.
Correl-id
----------
1111111
1111111
1111111
2222222
1111111
1111111
1111111
2222222
Now I want to read all messages with match CIDs and process them and write into a file.
Options tried
---------------
1) MOVE MQMI-NONE TO MQMD-MSGID
MOVE MQCI-NONE TO MQMD-CORRELID
then got all, but same order as above...
2) MOVE MQMI-NONE TO MQMD-MSGID
commented this ****MOVE MQCI-NONE TO MQMD-CORRELID
then got only mesgs with CID 1111111.
3) COMPUTE MQGMO-OPTIONS = MQGMO-NO-WAIT +
MQGMO-ACCEPT-TRUNCATED-MSG +
MQGMO-CONVERT +
MQGMO-FAIL-IF-QUIESCING +
MQMO-MATCH-CORREL-ID.
then also got only the CID 1111111.
So do I need to write any logic to move the new CID when it changes or is there any option to get the new CID automatically.
Please let me know.....................
I really appreciate for all your help.
Thanks |

| I guess you need to write a logic to move the new Correl-id when it finishes, processing of match Correl-id messages |
