Symptoms

Once a "LIBTUX_CAT:481: ERROR: Service xa_start returned XAER_RMERR" occurs we can not then get the service to restart.

xa_NULL01012013.trc has:

103945.1825.0: ORA-00028: your session has been killed

 

ULOG.010113 has the following for the same time period:

103945.mach!SERVERXASVC.1825.3646215968.0: gtrid x0 x515efda2 x1b9: TRACE:xa: { xa_start(0x0x872ad0, 0, 0x200000)

and nothing is shown in the ULOG related to the subsequent xa_NULL01012013.trc ORA-01012 errors:
