requested. If necessary, set
force_responses
to AP_YES to avoid
problems.
AP_NO
Request responses matching SNA
traffic.
def_data.keepalive_method
Method for sending keep-alive messages. Keep-alive
messages are sent to ensure periodic traffic on each
connection, so that connection failure is detected. If
keep-alive messages are not sent, a connection appears
to be active even if a client or network fails (for
example, if a client switched off). Keeping the
connection status as active under these conditions
wastes server resources and prevents LUs from being
used for other sessions. Possible values are:
AP_NONE
Do not send keep-alive messages.
This value is the default value.
AP_TN3270_NOP
Send Telnet NOP messages.
AP_TN3270_TM
Send Telnet DO TIMING-MARK
messages.
def_data.keepalive_interval
Interval (in seconds) between consecutive keep-alive
messages. The interval should be long enough to
minimize network traffic, especially if there are
typically many idle client connections. Typical values
are in the range 600-7200 (10 minutes to 2 hours). The
value 0 (zero) is not valid when the
keepalive_method
parameter is set to AP_TN3270_NOP or AP_TN3270_TM.
