Oracle RM Switch Module

Provides the information required to build an Oracle RM switch module.
Restriction: This topic applies only when the Enterprise Server feature is enabled.

We support Oracle RM switch modules for both Oracle 18 and Oracle 19 databases. [2]

Source Code
The Oracle RM switch module COBOL source file, ESORAXA.CBL is located by default in the %ProgramFiles(x86)%\Micro Focus\Visual COBOL\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.
Building the Switch Module
Method 1
  1. Start a Visual COBOL command prompt, 32-bit or 64-bit depending on the application, running as an administrator.
  2. Change to the %ProgramFiles(x86)%\Micro Focus\Visual COBOL\src\enterpriseserver\xa directory (default location).
  3. Enter build switch-module

    Where switch-module is either ora18 for Oracle 18 databases, or ora19 for Oracle 19 databases.

Method 2
  1. Start a Visual COBOL command prompt, 32-bit or 64-bit depending on the application.
  2. Copy all files from the %ProgramFiles(x86)%\Micro Focus\Visual COBOL\src\enterpriseserver\xa directory (default location) to any location where you have WRITE permission.
  3. Change to the directory containing the copied files.
  4. Enter build switch-module

    Where switch-module is either ora18 for Oracle 18 databases, or ora19 for Oracle 19 databases.

Build Output
The build process produces two binary RM switch module files from the ESORAXA.CBL COBOL source file:
Binary File Type
ESORAXA.DLL static
ESORAXA_D.DLL dynamic

You can register an RM switch module with Enterprise Server dynamically, or register it statically depending on which binary file you use. We recommend 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.
