Follow these steps to install a fix pack
During installation, the fix pack utility creates a log file named <install_path>/ctgfix/ctgfix.log. The log file contains details of each file that is updated by the fix pack, and details of any errors. Further information about error messages is available in text file ctgfix.hlp located where the fix pack was unpacked.
The fix pack utility updates Client daemon log messages to use English. If a language other than English is being used for Client daemon logging the ctgmsgs command must be run to change to the preferred language. For more details on running the ctgmsgs command, see Changing the system locale.
After installing the fix pack, the CICS Transaction Gateway version can be checked using the command cicscli -v The fix pack utility does not update the Windows registry or the AIX Software Vital Product Data database. The version of CICS Transaction Gateway displayed by Windows and AIX system utilities remains as the original installed version.
