Provides the information required to build an Oracle RM switch module.
Restriction: This topic applies only when the Enterprise Server feature is enabled.
- 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.
- Copy all files from the
$COBDIR/src/enterpriseserver/xa directory (default location) to any location where you have WRITE permission.
- Change to the directory containing the copied files.
- Enter
build ora
- Build Output
- The build process produces four binary RM switch module files from the
ESORAXA.CBL COBOL source file:
| ESORAXA.so |
32-bit |
static |
| ESORAXA64.so |
64-bit |
static
|
| ESORAXA_D.so |
32-bit |
dynamic |
| ESORAXA64_D.so |
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. 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.
