hello experts!
is there a way to just set some fields of the message context and let the queue manager set the putDate and putTime?
thanks |

Yes.....what fields did you have in mind?
Have you read the fine manual? (Application Programming Reference)
As for the put time and date, the Qmgr already does fill these in. |

By default, the queue manager sets date & time on PUT. AFAIK there's no way to actually stop it doing that...

This is of course the fastest way of answering questions like this. Along with the Application Programming Guide.

i would like to set the field PutApplName and let the queue manager set the other fields.
for that one need to use the open and put option set all context. but if i use it, putDate/Time are blank.
that's why i ask. |

If you use MQOO_SET_ALL_CONTEXT, then the qmgr does not set PutDate and Time ... he wants to be able to specify "some" fields (perhaps userid?) and not have to set putdate/time.... until he tells us exactly which fields he wants to set, we can't fully answer the question (outside of: yes, you can set identify context and allow the qmgr to set origin context).

Ok, then the answer is NO... if you use that SET_ALL_context, then you are responsible for all context fields ...

Why set PutApplName? It's not the most common requirement to allow the putting application to "pretend" to be another application. If you've got data to store there are better places in the MQMD to put it.
What put option context options have you specified?

what other places do you mean?
on open and put: MQxx_SET_ALL_CONTEXT
the default behaviour is that the qm or client set the identity and origin fields. for that, the necessary information is taken from the environment.
where is that information stored for windows and unix? |

I was thinking of the ApplOriginData & ApplIdentityData fields.

actually,
mq doc says that for changing the mqopen and put options the user has to have the right authority.
which authority? |

In fact, I know it's possible. I don't know *how*, but in some manner or another a COBOL program at my current site is sending NULL PutDate and PutTimes.

It is indeed. Taking my own advice (RTFM) you can deliberately set NO_CONTEXT and prevent the setting. Never seen it done and assumed it couldn't be.
I accept it's Friday, and time for some humble pie.
