On July 8th, Ivan and John was pushing for MQ related test. Someone deleted the working directory on test machine. It was late evening and as per reply in list, Ivan and John were working at that time.
[Appendix 100] – I reported politely provd directory being deleted.
[Appendix 200] – After I reported directory being deleted I sent another mail that I would send the logs after I configure it again. Ivan replied to the email and instructed to setup another MQ server on Windows. Point to note is John who was the developer was arguing something that was not the functionality. I had reported observations against John’s point of view. And before directory was deleted I was trying to verify John’s explanation.
I believe Ivan and John were trying to fail me in assignment or make me look crazy.APPENDIX 100

Something weired has happened. I tried to put some file from a directory to input directory. It couldn’t copy. I rebooted the server, provd directory is not there. Seems like data corruption.
Or anyone else using the same same setup?

The PS retries the recovery every 5 seconds. Are you saying that it never successfully re-establishes connectivity? You should see a log message “Re-initializing MQ runtime...” followed by “MQ initialization successful” if connectivity was re-established. If exceptions continually occur after the “Re-initializing MQ runtime...”, then perhaps the MQ Java classes are holding onto something in the VM that prevents re-connection. I’ve tried to gracefully shutdown and cleanup any MQ resources as part of failure detection, but that results in the VM hanging forever in MQ call(s).
Can you send me the log from your test?

Thanks John. In WAS behavior is different, probably because of connection Pooling?
But just verified doing so, it doesn’t recover. Also I remember multiple time when I had to take care of MQ and WAS, each time I restarted MQ provisioning server was being restarted by users.
Am I missing something John?

As part of recovery, I tear everything down and re-establish the QueueConnection, Session, QueueReceiver, QueueSender, and Queues.

Sure Ivan. I think answer should be no. As provisioning server will have session open.
I may be wrong.

Hi John,
If the Provisioning Server is running and MQ was restarted, would the ProvServer recover from that restart?
Anjan, please add this to your exception testing…
Thx,
Ivan

Anjan, if you’re planning to do more MQ restarts, can you setup another MQ server on a window’s box? I don’t want to interrupt 10.1.0.132 since others are using this for their testing.
Thx
