When RRS connects to WebSphere MQ, WebSphere MQ might have one or more in-doubt units of recovery that have not been resolved. If WebSphere MQ has in-doubt units of recovery that RRS did not resolve, one of the following messages is issued at the z/OS console:
Both WebSphere MQ and RRS provide tools to display information about in-doubt units of recovery, and techniques for manually resolving them.
In WebSphere MQ, use the DISPLAY CONN command to display information about in-doubt WebSphere MQ threads. The output from the command includes RRS unit of recovery IDs for those WebSphere MQ threads that have RRS as a coordinator. This can be used to determine the outcome of the unit of recovery.
Use the RESOLVE INDOUBT command to resolve the WebSphere MQ in-doubt thread manually. This command can be used to either commit or back out the unit of recovery after you have determined what the correct decision is.
