TABLE 42 Connectivity Map - TCPIP Outbound Settings (V3) (Continued)
Name Description
Receive Buffer Size A number indicating the receive buffer size. This is the value of the SO_RCVBUF
option for the current socket, which is the buffer size used by the operating system
for input on this socket. It provides an estimate of the size of the underlying
buffers used by the platform for incoming network I/O.
When used in set mode, this is a suggestion for the kernel from the application
regarding the size of buffers to use for the data to be received over the socket.
When used in get mode, this must return the actual size of the buffer used by the
platform when receiving data on this socket.
Send Buffer Size A number indicating the send buffer size. This is the value of the SO_SNDBUF
option for the current socket, which is the buffer size used by the operating system
for output on this socket. It provides an estimate of the size of the underlying
buffers used by the platform for outgoing network I/O.
When used in set mode, this is a suggestion for the kernel from the application
regarding the size of buffers to use for the data to be sent over the socket. When
used in get mode, this must return the actual size of the buffer used by the
platform when sending out data on this socket.
SoLinger An indicator of whether the adapter performs a “linger-on-close” timeout. This
option disables or enables an immediate return from a call to the close() method
for a TCP Socket. To enable the linger-on-close timeout, select true; otherwise,
select false.
If you enable this property, specify the maximum length of the timeout in the
SoLinger Timeout
property.
SoLinger Timeout The server’s linger–on–close timeout in seconds. Use SoLinger Timeout when
SoLinger
is set to true (see the description for SoLinger above). You can specify
an integer between -1 and 65535. The default is -1 seconds, which indicates that
the SoLinger option is disabled.
When SoLinger is set to true, the SoLinger Timeout value indicates the
following:
■ A non-zero integer means that calling close() will block pending the
transmission and acknowledgement of all data written to the peer. When all
data is written, the socket is closed gracefully. Upon reaching the linger
timeout value specified here, the socket is closed forcefully with a TCP RST. If
the specified timeout value exceeds 65,535 it will be reduced to 65,535.
■ A zero integer means that a forceful close is performed immediately.
