The pingfrequency parameter specifies
the frequency that ping messages are sent by the Gateway daemon to
attached Java and .NET Client applications to check that the applications
are still active.
pingfrequency=<number>- Description
- Set the value in the range 0 - 65,536 to specify the interval
period, in milliseconds, between pings. If a reply has not been received
by the time the next ping message is due to be sent, the connection
is disconnected. If work is still in progress on behalf of the connection,
the Client application can remain connected, depending on the setting
of the Drop working connections parameter. If the pingfrequency parameter
is not set or is set to zero, ping messages are not sent.
This
parameter is in the TCP protocol parameters subsection
of the GATEWAY section
of the configuration file.
Ping messages
are not sent to C Client applications. 
- Default value
- If this parameter is not specified, the default value is 60000
milliseconds.
