Linkedit COBOL with MQ Connection

Hi,

I was trying to linkedit a cobol program which open and put message into MQ. I have been trying to use the below JCL , but I am getting a message saying the variables MQPUT or MQCONN is not valid.

Hello,

You need to post more relevant information.

What was shown by the compile (end of the listing)?

Has anyone ever successfully used MQ on your system?

You should NOT be trying to use self-created jcl. Your system has standard compile and link jcl you should use. If there is no standard for MQ compile/link, then you (or your manager) need(s) to work with the people who support the compiler and link editor to create standard jcl for this.

you have probably missed putting the 'stubs' in the compile step.

as Dick said, your site has to generate the appropriate JCL for
compile/linkedit.

if you are also dealing with DB2 in the rununit,
you should be thinking of RRSAF,
which means a different type of mqsstub
as well as an appropriate set-up for the proper dsn... libraries.

all the info that you need about mqs is contained in the manuals
this link is to the WebSphere MQ Libraries
Pick your version and I suggest downloading all manuals
for future reference.

RRSAF info is contained in DB2 manuals as well as in
Vol 5 Chapter 3 of the ABC's of Systems Programming
Here is a list of all of the ABC's of Systems Programming (Redbooks)
suggested reading for anyone who desires to be aware of the Z/os environment.

Probably your system has aliases for MQCONN and MQPUT so it fails

So as others said you need to check with people who knows the system well

A linkedit for MQ uses linkedit controls cards to specify the 'stub' to be included in the linkedit. - the linkage editor/binder does not find the required module automatically. This is because the MQ calls in the program are to entry-points within the appropriate 'stub' module - CSQBSTUB, CSQQSTUB or CSQCSTUB .

Garry, When I was working at your place I did an MQ program and remember nothing of this because, I presume, it was all set up in ChangeMan. So I guess the TS should check to see if he is using the correct options in whatever source control app he is using (ChangeMan/Endevor/whatever). Here, down the road from you, we use Endevor but no MQ so I cannot look it up.

Garry,
thx for the post and clearing-up a few misstatements

Sorry for not putting the actual error message which I was getting.

I was trying to compile and link edit the program, and I was getting the below error yesterday while Linkedit

IEW2278I B352 INVOCATION PARAMETERS - XREF,LIST,MAP,RMODE=ANY,SIZE=(2048K,256K)
IEW2456E 9207 SYMBOL MQCONN UNRESOLVED. MEMBER COULD NOT BE INCLUDED FROM THE DESIGNATED CALL LIBRARY.
IEW2456E 9207 SYMBOL MQOPEN UNRESOLVED. MEMBER COULD NOT BE INCLUDED FROM THE DESIGNATED CALL LIBRARY.
IEW2456E 9207 SYMBOL MQPUT UNRESOLVED. MEMBER COULD NOT BE INCLUDED FROM THE DESIGNATED CALL LIBRARY.

As Garry and dbzTHEdinosauer suggested, I tried including the Stubs and it worked. Thanks a lot!

Good to know you got it working.

Garry

dbzTHEdinosauer · Posted: Fri Sep 07, 2012 3:03 pm

I mentioned using stubbs.

Garry told you where to use them.

kudos go to Garry for his accurate (as always) comments.
