CICS definitions

This section explains the CICS definitions for the sample Token-Ring network and includes the following subsections:

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.
