When setting up a Java™ EE
application to participate in a global transaction, you must select
the appropriate communication protocols and RSS must be enabled on IMS™.
- IMS must be enabled for Resource Recovery Services
(RRS) processing. To ensure that IMS is
enabled for RRS processing, check that the RRS value in the startup
parameter within your IMS environment is set to Y.
This setting will be displayed in the job logs generated when IMS is
brought up.
- If you are using two-phase commit processing with TCP/IP, you
need to enable IMS Connect for RRS processing by either issuing
the IMS Connect command SETRRS ON or set RRS=Y in
the IMS Connect configuration file.
