An HFS file or MVS™ dataset can be used to initialize the CICS® Transaction Gateway.
The default configuration used by CICS Transaction Gateway is the HFS file <install_path>/bin/ctg.ini You can modify the directory and filename if required. For more information see the CICSCLI environment variable in Environment variables: remote mode.
To denote comments in the configuration file use the hash (#) character. The hash (#) character must be positioned at the start of the line, or must have a space or tab character before it.
To split definitions over multiple lines, use backslash (\) as a continuation character. The continuation character should be the placed immediately after the last non-blank character on the line.
A sample HFS configuration file and a MVS dataset configuration are supplied with the product. These sample configurations can be copied and modified as required. The sample HFS configuration file is located in <install_path>/samples/configuration/ctgsamp.ini. The sample MVS dataset member is CTGCONF in the CTGSAMP dataset.
The configuration file must contain at least the GATEWAY section with a TCP protocol handler definition, otherwise CICS Transaction Gateway will not start. A section begins with a SECTION element and must be terminated with an ENDSECTION element. Each SECTION element must be positioned as the first entry on a given line.
For information about configuration parameters and supported values see the parameter descriptions in Configuration parameter reference.
Default values are automatically applied to parameters that are not explicitly defined.
