The CICS® Transaction Gateway does
not support a restart of the Resource Recovery Services (RRS) while
any instances of the Gateway are running.
If RRS is restarted, a message is written to the JNI log.
The following limitations apply to EXCI extended LUW and
XA transactional
requests.
- Non-transactional requests continue to work.
- The CICS Transaction Gateway must
be restarted before transactional requests start working.
