This section explains the CICS definitions for the sample Token-Ring network. It includes the following subsections:
Define the CICS APPLID to SNA, as shown under “APPL definition statement”.
Set these parameters as follows for CICS version 3.x and later:
ISC=YES
TCP=YES
SEC=YES, if using an external security manager
SNA=YES
Use the following sample as a model. Change it, as appropriate to your site, noting the requirements listed after the sample:

Requirements include the following:
The connection and session are related by the Connection parameter in the OBJECT CHARACTERISTICS and SESSION IDENTIFIERS definitions.
The Netname parameter corresponds to an LU name defined to SNA.
Set the SInglesess parameter to Yes for dependent LUs.
Set AUtoconnect to No for single sessions.
For conversation-level security:
Set the SEcurityname parameter to a user ID specified in the CICS sign-on table, or use the default sign-on table entry and enter a valid RACF ID.
Set the ATtachsec parameter to Verify.

Requirements include the following:
The connection and session are related by the Connection parameter in the OBJECT CHARACTERISTICS and SESSION IDENTIFIERS definitions.
On the SESSION definition, set MAximum=001 000. This setting both defines one session for the LU and sets CICS as the contention loser, improving performance during session initiation (BIND).
Set SENDSize and RECEIVESize to match the value specified in the RUSIZES parameter of the chosen logmode.
AUtoconnect determines whether CICS attempts to bind sessions when the connection is established. Set this parameter to No.
