If you intend to use Adabas Transaction Manager through the CICS Resource Manager Interface (RMI), use the following installation procedure in conjunction with the installation procedure for the Adabas task-related user exit (TRUE) described in the Adabas Installation for z/VSE documentation.

Note:
A supported level of IBM’s CICS is needed, with RMI configured in it.


Installation Overview

The steps needed for a successful installation are as follows:

Step Description
1 Perform standard installation procedure for Adabas Transaction Manager, and verify the installation.
2 Follow the steps for the installation of the Adabas TRUE.
3 Establish CICS definitions for Adabas Transaction Manager RMI programs.
4 Copy the Adabas Transaction Manager RMI modules into a CICS RPL library.
5 Define client runtime controls for the CICS system.

Installation Procedure

The following is the general RMI installation procedure. All steps are required for a successful installation.

Step 1: Install Adabas Transaction Manager

Install and verify the execution of the transaction manager and client proxy without activating the RMI.

Step 2: Install the Adabas TRUE

This process is fully described in the Adabas Installation for z/VSE documentation.

Note:
When linking the Adabas command-level link component, you must link in the Adabas System Coordinator stub module.

Step 3: Establish CICS Definitions for the RMI Programs

Start of instruction setTo establish CICS definitions for the RMI programs:

Step 4: Copy RMI Modules into a CICS RPL library

The following programs, supplied in the ATM load library, must be made available in the LIBDEF concatenation of your CICS JCL procedure:

ATMRMIRS

Step 5: Define Client Runtime Controls for CICS

Use Adabas Transaction Manager Online Services to define the required client runtime controls for the CICS job.

The required controls are described in section Parameters. Some special considerations are necessary when running with the RMI active. Define a set of client runtime controls for the CICS job. Pay particular attention to the Open distributed transaction support, Adabas transaction dynamics and Transaction control by other vendors, as well as the Transaction control by 'cc' client controls.

Step 6: Activate CICS Resource Manager Interface

Start of instruction setTo activate the CICS Resource Manager Interface:

  1. Ensure that the Adabas System Coordinator daemon, within which the Adabas Transaction Manager is running, is active

  2. Start CICS.
