gw/timeout

Specifies the timeout value for the establishing connections to other gateways in milliseconds (NiConnect calls). If a connection to the other gateway is not made within this time interval, an error is reported to the calling program.

Value 0 means that non-blocking connections are opened.

gw/internal_timeout

Specifies the timeout value for NiRead and NiWrite calls in milliseconds. If not all the data has been sent or received within this time interval, the action concerned is interrupted and reinitiated later on. Thus slow connections cannot block the gateway. Value 0 deactivates the timeout.

gw/frag_timeout

Determines the timeout for incomplete network write operations.

If the gateway cannot write all the data to the network, the connection is closed once this time is exceeded.

Value 0 deactivates the check.

gw/conn_pending

Specifies the maximum number of seconds for which a connection can remain in the status CONN_PENDING. If this time interval is exceeded, the connection is closed by the gateway. This status is set when a connection is opened to another gateway, external program or SAProuter, when the handshake is not yet completed, or when an external program connects to the gateway using TCP/IP connect and then sends no further data to the gateway (for example, telnet <host> 3300 or ftp).

The value 0 deactivates this check.

gw/gw_disconnect

Specifies the maximum number of seconds for which a GW-GW connection can remain inactive. If this time interval is exceeded, the connection to the other gateway is closed. This is only the case if there is no active CPIC/RFC connection to this gateway. If you set this parameter to 0, these connections are not closed.

gw/deallocate_timeout

Time period in which the network connection for a DEALLOCATE must be closed. If the connection is not closed within this time period, the gateway closes the connection itself.

This check is only made on external connections (they appear as NORMAL_CLIENT in the gateway monitor).

The value 0 deactivates this check.

gw/max_sleep

Specifies the maximum time in seconds for which the gateway read process sleeps on the select.

Periodic checks within the gateway can be made a maximum of every gw/max_sleep seconds. These include:

gw/keepalive

Specifies the maximum time period (in seconds) before the system checks, using a ping, whether the partner is still alive when there is no data transfer across a CPIC connection.

gw/reg_keepalive

Specifies the maximum time period in seconds before the system checks, using a ping, whether the partners are still alive in a registered server program with the status WAITING.

gw/conn_disconnect

Specifies the maximum number of seconds for which an active connection can remain in the status DISCONNECT or DISCONNECTED. If this time interval is exceeded, the connection is closed by the gateway.

If you set this parameter to 0, such connections are not closed.

gw/cpic_timeout

Specifies the maximum wait time for a connection setup. The wait time must not exceed the interval defined by the parameter (in seconds). Otherwise the connection setup is terminated with a timeout. This parameter is passed on to the CPIC interface via putenv and defines the shell variable CPIC_TIMEOUT.

gw/resolve_timeout

This parameter is used to activate a time measurement for the network lookup calls (host name - IP address, service name - port number). If the time in milliseconds exceeds the value of this parameter, the call with parameters is logged in the trace file.

The time period is specified in milliseconds in the parameter.

Value 0 deactivates the time measurement.

gw/reg_timeout

Specifies the maximum wait time for setting up the connection with a registered program. The wait time must not exceed the interval defined by the parameter (in seconds). Otherwise the connection setup is terminated with a timeout.

gw/close_routes

Specifies the period (in seconds) after which a route to a remote gateway through which a CPIC connection is open is closed.

gw/nibuf_retry

Time period after which the invalid entries are deleted in the host name buffer. An invalid entry can arise, if for example, an IP address cannot be converted into a host name.

If the parameter value is not set, the default value of the network layer is used (600).

The value 0 means that the invalid entries are never deleted.

gw/accept_timeout

Maximum allowed time period for the login process of a server program. If this time is exceeded, the connection is closed. The waiting client is informed of the error.

A parameter value of 0 deactivates the check
