Restrictions apply when you are using CICS® Transaction Gateway in a sysplex environment.
The CICS Transaction
Gateway instance must run on the same LPAR as the CICS server to which it is sending requests
if you are using EXCI connections with one of the following:
- The ECI resource adapter for global transactions
- A Client application for extended LUW requests
You can start a Gateway daemon in an HA group in any LPAR in the
sysplex but you must ensure that the same RRS logging group is used
in each LPAR.
