Use the <install_path>/bin/ctgasi command to refresh CTGRRMS services that are used for XA support. ctgasi must be run in a UNIX System Services shell. It can be launched in batch mode using CTGBATCH.
Follow these steps after successfully installing CICS Transaction Gateway and before running any Gateway daemons. If you do not follow these steps for every LPAR, Gateway daemons will fail to start.
A Gateway daemon, or version of ctgasi, from an earlier release cannot run a CTGINIT file from a later release. The version of ctgasi which invokes CTGINIT and causes the service to be refreshed must be from the later release.
