General information about messages

Information about message locations, formats, and prefixes.

Message locations

The Gateway daemon and Client daemon use different logs, the configuration file defines where log messages are written. See Gateway daemon logging and Client daemon logging for more information.

Message format

Messages have the following format:
CTGnnnnt: <message text>
where nnnn is a number, and t is one of the following:
Identifier Purpose of message Written to
I information Information logs
E error Error logs
W warning Error logs

Message redirection

On UNIX and Linux platforms, all CICS Transaction Gateway messages can be optionally redirected to standard error, and standard error can be written to a file called outputfile. To do this, use the following command:
ctgstart 2>outputfile >&2

For more information about redirecting messages, see the documentation for your operating system.

Message prefixes

CICS Transaction Gateway messages have the prefix CTG. Client daemon messages have the prefix CCL.

For an explanation of all CICS Transaction Gateway messages, see Messages.

API errors

Error codes resulting from incorrect use of the APIs are returned to the associated applications. Applications must notify the user about such errors, and must provide information on the required user response.
