Using CICS Transaction Gateway, High Availability, and the CICS Explorer

An IBM Redpaper publication

Authors: Rob Jones


This IBM® Redpaper™ publication describes how the CICS® Explorer™ can be used to aid configuration and administration of the CICS Transaction Gateway for z/OS®. Starting from a basic system configuration, it takes you through the steps to create a high availability topology and implement request monitoring.

At a high level, the procedures described are:

  • Configure CICS Transaction Gateway (CICS TG) for z/OS
  • Set up the CICS TG plug-in for CICS Explorer
  • Start up and administer the Gateway daemon on z/OS
  • Configure CICS Transaction Server (CICS TS) connections to CICS TG
  • Configure CICS TG connections to CICS TS
  • Configure and run a test ECI workload
  • Configure Dynamic Server Selection in the Gateway daemon
  • Configure request monitoring in the Gateway daemon

It is assumed that the reader has CICS Explorer available with the CICS SM and z/OS perspectives operational.
