XAID

Simplifies working with multiple XARs of the DB2 RM type defined in a single enterprise server region.

Syntax:

XAID=xarid[_s|_S]

Parameters:

xarid: The XAR ID set in the enterprise server region XAR definition.
[_s|_S]: The XA resource will use static registration. If not specified, the XA resource will use the DB2 default of dynamic registration in distributed transactions. In most cases, dynamic registration is more efficient then static registration.

Properties:

Default:

None

Comments:

Compiling CICS applications with XAID is mandatory when using the DB2 RM switch module for dynamic registration that are also configured to run with User Impersonation or PACKAGEPATH. Using XAID is not required for other batch processing, including IKJEFT01, DSNALI., and DSNRLI.

See RM Switch Module Registration and the PACKAGEPATH=schema1 section in SQL xa_open string Configuration Options for more information.
