Open String, Free Format

Specify the string that is passed to the resource manager on the xa_open() call. An entry in this field usually contains at least the database name, and the user ID and password for connecting to the database. The contents of this string are database-specific.

For DB2, the contents are documented in IBM's DB2 Administration Guide; for additional information see the Application Programmer's Guide.

For Oracle, see the Oracle Application Developer's Guide - Fundamentals.

Where the resource manager supports dynamic registration, and the database vendor requires the name of the module that provides the ax_reg function, you should specify casaxlib.

Specify the string that is passed to the resource manager on the xa_close() call. To find out whether or not you need to supply Close string, see your database vendor's documentation.

Load Module

Choose an external resource manager that the server needs to communicate with on behalf of container-managed applications.

Load Module, Name

if you chose User in Load Module, specify the name of the module that supplies the run-time support for the database calls made by the application.
