Duplicate SESSION or modegroup-name for CONNECTION (DFHZC5939).
Explanation
A SESSION (MODE Group) was encountered whose NAME
value duplicates that of another definition.
Note that the other definition could be a
CONNECTION, SESSION, or TERMINAL definition.
Alternatively, it could also be the Local
Connection whose name is specified by SYSIDNT in
the system initialization table (SIT).
This is a Deployment Analysis message; during an
actual CICS start-up, one would expect message
DFHZC5939E to be issued for this condition.
System action
The SESSION definition is reported as "not
installable".
User response
Examine the SESSION definition and assign it a
unique name, or change/remove other definitions
to ensure that they have a non-conflicting NAME
value.
