Provides the information required to build the IBM DB2 RM switch module.
- Source Code
- The IBM DB2 RM switch module COBOL source file,
ESDB2XA.CBL is located by default in the
%ProgramFiles(x86)%\Micro Focus\Enterprise Developer\src\enterpriseserver\xa directory.
Note: If you prefer to supply user credentials programmatically 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
- You can use either of the following methods to build the IBM DB2 switch module:
- Method 1
-
- Start an
Enterprise Developer command prompt, 32-bit or 64-bit depending on the application, running as an administrator.
- Change to the
%ProgramFiles(x86)%\Micro Focus\Enterprise Developer\src\enterpriseserver\xa directory (default location).
- Enter
build db2
- Method 2
-
- Start an
Enterprise Developer command prompt, 32-bit or 64-bit depending on the application.
- Copy all files from the
%ProgramFiles(x86)%\Micro Focus\Enterprise Developer\src\enterpriseserver\xa directory (default location) to any location where you have WRITE permission.
- Change to the directory containing the copied files.
- Enter
build db2
- Build Output
- The build process produces two binary files from the
ESDB2XA.CBL COBOL source file:
| Binary File
|
Type
|
| ESDB2XA_S.DLL
|
static
|
| ESDB2XA.DLL
|
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.
