Folks, I have been trying to set my own accountingtoken before putting the message, but I had no success.
I´ve read that I shall use some parameters for opening the file as well for the put message options....but I still seeing my messages with the accoutingtoken set with MQ internal values...
Any ideas?
code snippet below:
| Code: |
MQPMO P_options = {MQPMO_DEFAULT + MQPMO_SET_IDENTITY_CONTEXT};
LONG O_options = MQOO_OUTPUT + MQOO_SET_IDENTITY_CONTEXT;
MQOPEN(Hconn, &od, O_options, &Hobj, &CompCode, &Reason);
memcpy(md.AccountingToken, pMQXQH->MsgDesc.AccountingToken, MQ_ACCOUNTING_TOKEN_LENGTH);
MQPUT(Hconn, Hobj, &md, &P_options, *pDataLength, pMQXQH, &CompCode, &Reason);

Is AccountingToken part of Identity Context?
Or do you need to use a different Context?
Also, do you need to adjust the MQPMO as well?
I'm guessing you've checked these... but I'm asking the question because I haven't checked in a while.

Hmmm did you check the reason code after your mqopen and mqput?
If so what were they?
That will help a lot in determining what's wrong. Likely is that you don't have authority to set context, but ...

Not sure if the code is 100% right, but both return '0'...
| Code: |
MQPUT(Hconn, Hobj, &md, &P_options, *pDataLength, pMQXQH, &CompCode, &Reason);
char temp[10];
sprintf(temp, "%ld", Reason);
wlog(temp);
sprintf(temp, "%ld", CompCode);
wlog(temp);
void wlog(char *logmessage){
..write message in text file...
}
|
output:
MQExit.dll - 200801281526 - 0
MQExit.dll - 200801281526 - 0

Wait?
This is inside an exit?

Are you sure you're allowed to update the MQMD inside whatever exit this is?
Are you trying to create a copy of a message, and log it somewhere?
Or edit a message that is "in flight"?

I am copying some fields of one message (the one flowing the channel) into a fresh message that is put into a local queue, it´s for control purposes.
A job goes into this local 'log queue' containing these semi-cloned (not all fields are cloned - only the correlid and the accounting token) and stores in a database as a proof of send.
I don´t see any reason why MQMD cannot be changed before the MQPUT since it is a fresh structure. I do understand that MQPUT may overwrite some fields, and thats why I was using those open and put options (they seem to override the MQPUT behaviour on the overwriting).
It may be something related to user privileges like anoter fellow said. There are constraints on who may open a file with these override options, but the returned Reason and CompCode do not help on this issue.

Hi,
I'm surprised that the compiler didn't give you an error message because MQPMO_DEFAULT is an array initializer and MQPMO_SET_IDENTITY_CONTEXT is an integer.
Your code should look like:
| Code: |
MQPMO pmo = {MQPMO_DEFAULT};
MQLONG O_options;
...
O_options = MQOO_OUTPUT + MQOO_FAIL_IF_QUIESCING + MQOO_SET_IDENTITY_CONTEXT;
MQOPEN(Hconn, &od, O_options, &Hobj, &CompCode, &Reason);
memcpy(md.AccountingToken, pMQXQH->MsgDesc.AccountingToken, MQ_ACCOUNTING_TOKEN_LENGTH);
pmo.Options = MQPMO_SET_IDENTITY_CONTEXT + MQPMO_FAIL_IF_QUIESCING;
MQPUT(Hconn, Hobj, &md, &pmo, *pDataLength, pMQXQH, &CompCode, &Reason); |
Also, when you use the SET_IDENTITY_CONTEXT option, it is the programmer's responsibility to set 3 fields of the MQMD:
- UserId
- AccountingToken
- ApplIdentityData
You will need to set the other 2 fields or they will appear as blank (null).
Hope that helps.

'Grand Lacroix!' It worked, I did not notice the MQPMO vs. MQLONG types.

As a general rule you shouldn't use + when manipulating (for example) the PMO, you should use | (logical OR). + will work much of the time, until you "mess up".
