Requirements of ISC TCP/IP support

The requirements for the ISC TCP/IP function include requirements for CICS®, ETO, IMS Connect, and a minimal CSL.

• IBM® CICS Transaction Server for z/OS®, Version 5.1 (or later) must be used.
• IMS Connect is required to provide TCP/IP socket connection support for IMS.
• The Common Service Layer (CSL) with at least the Structured Call Interface (SCI) and the Operations Manager (OM) is required. SCI is required for communications between IMS and IMS Connect and OM is required for type-2 command support.
• A single point of control (SPOC) program, such as the IMS TSO SPOC, must be used to issue type-2 commands to the OM API or REXX SPOC API.
• For each IMS subsystem that uses dynamically defined terminals with ISC TCP/IP, the IMS Extended Terminal Option (ETO) is required.
