APAR status
Closed as program error.

Error description
In a 2-way WASfz sysplex, there are replicated EJB servers
running (one server per system).
When a server fails and is restarted by ARM in the same system
it tries to register itself to WLM by IWMSRCRR. This call fails
which results this server will never be recommended by Daemon
in future because of IWMSRCRN failure (C9C2116D). All subsequent
client requests will be processed by the other server in the
other system.

****************************************************************
Control Regions which start out of place are not
to receive new work.  The code which parses the
system name to determine if the Control Region is
on the right system is incorrect causing the ARM
restarted Control Region to always believe it is on
the wrong system.  This causes the Control Region
not to register with WLM so the Daemon will not
recommend it unless there are no replicas active.
Problem conclusion
Corrected the coding errors in the parsing of the
system name in module bbocsmgr.cpp.

APAR PQ54976 is associated with SERVICE LEVEL W400056 of
