Hi all,
I have an application which use MQ, and muti-thread to get messages from queue, but when exceptions occur, I find if I use qMgr.backout(), all of the messages which the application has received will be rollbacked include the uncommitted right messages in other thread?
Any suggestions? |

| Are all of your units of work sharing the same connection handle? |

Yes, all the thread shared only one qMgr instance
but if I didn't use only one qMgr, the application will throw mq exception |

| Units of work are handled on a per connection basis. If you are sharing the connection, then a rollback (or commit) will process all outstanding units of work. What version of WMQ are you using? How are you connecting to the qmgr (ie, the exact call)? What is the exception? |
