TABLE 17 Connectivity Map - TCPIP Outbound Settings (Continued)
Name Description
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.
SoTimeout The value of the SoTimeout in milliseconds. You can enter a value greater than or
equal to zero (0). When set to zero (0), the timeout is infinite.
With this option set to a non-zero value, calling the read() method on the input
stream associated with this socket will block for only the configured length of
time. If the timeout expires, a java.io.InterruptedIOException or
java.net.SocketTimeoutException
is thrown, but the socket remains valid.
Enable this option prior to entering the blocking operation.
TcpNoDelay An indicator of whether data packets that are smaller than the maximum transfer
unit (MTU) size are sent out immediately over the network (this refers to Nagle’s
algorithm). Select one of the following options:
■ True – Indicates that the server allows data packets that are smaller than the
MTU size to be sent out immediately over the network. This can improve
performance for higher-speed networks.
■ False – Indicates that the server does not allow data packets that are less than
the MTU size be sent out immediately over the network.
This is used for the accepted client socket.
