Oracle RM Switch Module

Provides the information required to build an Oracle RM switch module.
Source Code
The Oracle RM switch module COBOL source file, ESORAXA.CBL is located by default in the $COBDIR/src/enterpriseserver/xa directory.
Note: If you prefer to supply user credentials programatically rather than in the xa_open string, instructions for doing so are provided in the COBOL source file in the Customization section.
Build Requirements

The build script uses the current effective working mode to determine how to build the switch module. Before invoking the build script, ensure that your database environment is set up correctly. For details see your database vendor's documentation.

Building the Switch Module
The $COBDIR/src/enterpriseserver/xa directory contains the build batch file that you can use to build the switch module.
  1. Copy all files from the $COBDIR/src/enterpriseserver/xa directory (default location) to any location where you have WRITE permission.
  2. Change to the directory containing the copied files.
  3. Enter build ora
Build Output
The build process produces four binary RM switch module files from the ESORAXA.CBL COBOL source file: 32-bit static 64-bit static 32-bit dynamic 64-bit dynamic

You can register an RM switch module with Enterprise Server dynamically, or register it statically depending on which binary file you use. Micro Focus recommends that you use the dynamic switch module option, as this ensures that only active databases used in the global transaction participate in the TM/RM XA flow.
