I found a message in one of my queues with some unusual data.
I'm showing PutDate, PutTime, Format and a few other fields as spaces (I think - they don't actually show in hex, just as whitespace on the page). They show as spaces under amqsbcg.
I thought PutDate/PutTime were created by MQ internally, so I'm confused how I could get spaces.

I only have a print copy of the message header.
This was a production system, so my primary goal was removing the problematic message. It was causing a logging process to abend.
I didn't notice the odd data until hours later when looking at the message header.
For the lines in question, I see:
| Code: |
| PutDate : ' ' PutTime : ' ' |
Best I can do

Hi,
Yup, I've seen this before. The sending application set the option of either:
- "Set All Context" but they did not fill in the MQMD fields or
- "Set No Context"
Hence, those fields are blank. Tell the developer not use use that context option in their application.

A programmer can specify MQPMO_NO_CONTEXT with no additional authority requireed - beyond the auth to put to the queue.
NO_CONTEXT tells the qmgr to clear all the context fields.
This can be tested by looking in the PutApplType field of the MQMD for MQAT_NO_CONTEXT value.
Please post the MQMD for the offending message.
