EXCI connections are MRO, both for GENERIC and SPECIFIC
connections.

Group DFH$EXCI has a good definition for both Generic (EXCG)
and Specific (EXCS).  The default number of sessions is too
low, but if you were to copy these definitions to a group of
your own and install it instead, you could alter the session
count.

There can be only one Generic connection installed in the
region.  You can have any number of Specific connections, but
they need to have unique names & unique APPLID (aka Pipe
Name) specified.

Client applications coded using the EXEC LINK syntax are
restricted to the Generic connection.  In order to use a
specific connection, you must be using the CALL syntax. Those
applications coded using the CALL syntax can also use the Generic
connection.

CICS TG specifies the Pipe Name in the DFHJVPIPE environment
variable.  If the variable is null, then the CICS TG will use
the Generic connection.  If there is any value specified, then
the CICS TG will use the Specific connection which has the same
Pipe Name in its definition.  The sample Specific Connection has
a Pipe Name of BATCHCLI.

Hope this helps you.
