Hi All,
We're building a web utility that allows users to unload and reload messages from their queues. When the message if pulled from their queue, it is being stored in DB2, inclusing info from the MQMD. When they reload the message using our web utility, the message, and MQMD info is put back onto the queue.
However, we want to set the MQMD Userid to the user signed on to our Web Utility instead of letting MQ set it to our Web Utility ID. I've been reading Context;
MQOO_SET_IDENTITY_CONTEXT
MQPMO_SET_IDENTITY_CONTEXT
MQOO_PASS_ALL_CONTEXT
MQPMO_PASS_ALL_CONTEXT
And it doesn't seem that this will work for us. As I understand it, using Set Identity, the queue manager does not set any of the other fields other than what I've specified.
Do you know how we can assign the MQMD userid to be the signed on user instead of MQ assigning the putting application?
Thanks!!!!! |

But as you've got the original MQMD, why is this an issue?

When the web utility issues the put, MQ is assigning the Web Utility's ID as the User Identifier in the Message Descriptor. Also, the user who unloaded the message may not be the same user that reloads it. |

Do you purposely choose to not be helpful? I've read several of your posts on this forum and it seems if you don't really wish to help, you would just stop replying. |

No, if I choose to be unhelpful I do something completely different.

Sometimes the temptation to do just that is very strong.
The point I was getting at here is I don't understand why, in the context of your post, the SET_IDENTITY option is unsuitible for you. It seems clear that you're trying to deliberately set the id from that which was used to originally put the message to that used to reload the message, and you've identified that using this option will cause the queue manager not to set any other identify fields.
But, to return to my original question which has seems to have irritated you so, why can you not set these other fields from the original MQMD stored with the message? Clearly you can't, or you wouldn't have posted, but I don't see the issue and was looking for some additional clarification from yourself before advising you further.
Oh well.

Presuming you're using Java with MQ in your Web utility, you can set the userID via com.ibm.mq.MQEnvironment
MQEnvironment.userID = "SUNNY"; |
