Configuring XA support

This information describes what you must do to configure your system for XA support.

Configuring for XA transaction support
You can configure CICS Transaction Gateway to benefit from XA transactionality. XA transactionality provides support for two-phase commit transactions and allows CICS Transaction Gateway to participate in global transactions. This section describes how to configure a single CICS Transaction Gateway and multiple CICS Transaction Gateways in a highly-available Gateway group.
Enabling CTGRRMS services
To support XA, CICS Transaction Gateway issues authorized RRS calls, through CTGRRMS services. Protect these services with RACF®, or another external security manager. Follow these instructions to add the new services, and to protect them.
Starting, stopping or refreshing the CTGRRMS services
Use the <install_path>/bin/ctgasi command to start, stop or refresh the CTGRRMS services that are used for XA support.
XA transaction support activate (xaSupport)
The xaSupport parameter controls whether the CICS Transaction Gateway supports XA transactions.
Gateway start type
The start parameter determines whether heuristically-completed transactions are resolved.
