More than one UR was found associated with an XID during an XA request: number of URs = number
An XA transaction is identified by an XID. This maps directly to an RRS unit of recovery. In this case, more than one unit of recovery mapped to the XID used on an XA Request.
The XA request will fail. Manual intervention will be required to resolve the URs.
Check the RRMS logs for the XID and resolve the URs via the ISPF panels. The XID can be looked up via the RRS queries to find out more information about the URs and associated resource managers.
