Changing configuration information

 

After the queue manager has successfully started to coordinate global units of work, do not change any of the resource manager configuration information.

If we need to change the configuration information we can do so at any time, but the changes do not take effect until after the queue manager has been restarted.

If you remove the resource manager configuration information for a database, you are effectively removing the ability for the queue manager to contact that database manager.

Never change the Name attribute in any of your resource manager configuration information. This attribute uniquely identifies that database manager instance to the queue manager. If you change this unique identifier, the queue manager assumes that the database has been removed and a completely new instance has been added. The queue manager still associates outstanding units of work with the old Name, possibly leaving the database in an in-doubt state.
