DB2 FOR LUW / DB2FORLUW / A50 - DB2

This situation might happen when distributed transaction take 
place DB2 z/OS server(resource manager - RM) reports ABEND. 
DB2Connect server is configured in the connection path with 
connection concentrator enabled to handle TM using 
mufti-transport model like Tuxedo. 
DB2 z/OS ABEND causes connection reroute between DB2Connect 
Server and DB2 Z/OS. Transaction is marked for rollback only. TM 
sends xa_end and xa_rollback to rollback the transaction. XA_END 
receives XA_RBOTHER and XA_ROLLBACK request hang on DB2Connect 
Server. 
 
For example when Tuxedo Transaction Manager is configured on DB2 
Connect Server and application abnormal ends on z/OS. 
In the Tuxedo logs the information regarding ABEND, xa_end = 104 
and hang on xa_rollback can be found. 
 
Apply the APAR on client.
