z/OS Communications Server
NOTES
- BNDYN=LIMITED will only add an ADJACENT Border node to the
Adjacent Cluster table if the NETID for that Border Node matches the
NETID in the session request. If this border node does not have a
direct connection to the other NETID then the session will fail unless
the Border Node within this NETID that connects to that NETID is
specifically added to the Adjacent Cluster Table.
- VTAM Start option SNVC for the Subnet Visit Count defaults to 3.
If the
DLU is more than 3 NETIDs away including this NETID the session will
fail. SNVC can be over ridden on the ADJCLUST table. Any Border node on
the search path can reduce the Subnet visit count by the SNVC
definitions in that host but can not increase it.
- A DSME (Directory Services Management Exit) ISTEXCDM can be coded
to
control border node and or general APPN search logic. D
NET,EXIT,ID=ISTEXCDM can be issued and will tell you if this exit is
active.
- A CDRSC can be predefined in the OLU host with NETID so that VTAM
picks
the correct ADJCLUST table for the session. However this can add quite
a bit of pre definition of CDRSCs. In VTAM release V1R4 and above you
can now code the CDRSC on the Network Node servers. By adding keyword
CPNAME to the CDRSC VTAM will now learn the
NETID at the Network Node server and select the correct ADJCLUST for
that NETID instead of the default table.
