Both 'CTG.INI' and 'ctg.ini' configuration files exist, using default file 'ctg.ini'
The default directory contains both uppercase and lowercase versions of the configuration file.
The Gateway daemon will use the default file 'ctg.ini' as no configuration filename has been specified. The contents of file 'CTG.INI' will be ignored.
To avoid this warning being issued, explicitly specify a configuration file or delete file 'CTG.INI' from the default directory. For details of how to specify a configuration file refer to the CICS® Transaction Gateway Information Center.
