keepalive-count
Number of consecutive TCP keepalive probes that can be sent without receiving a response. After this count is reached,
the client or server sending the probes declares that the recipient is offline. You can use this property with either a
Description
SQLFire client socket (to determine when a server is offline) or a SQLFire network server socket (to determine when
clients go offline). To use this property with a SQLFire thin client, include the jna.jar library in your CLASSPATH.
Note: Windows platforms do not support per-socket configuration for keepalive-count. As an
alternative, you can configure a system-wide keepalive-count value in some versions of Windows.
See http://msdn.microsoft.com/en-us/library/windows/desktop/dd877220%28v=vs.85%29.aspx. Windows
Vista and later versions keep this value fixed at 10.

keepalive-idle
TCP keepalive idle timeout in seconds. This is the idle time after which a TCP keepalive probe is sent over the socket
to determine if the other side of the socket is alive. You can use this property with either a SQLFire client socket (to
Description
determine when a server is offline) or a SQLFire network server socket (to determine when clients go offline). To use
this property with a SQLFire thin client, include the jna.jar library in your CLASSPATH.
Note: On Solaris platforms prior to r10, system-wide TCP keepalive settings must be changed to larger values
(approximately 30 seconds) in order to detect server failures by clients and vice versa. See
http://docs.oracle.com/cd/E19082-01/819-2724/fsvdg/index.html. This also applies to other non-Linux,
non-Windows platforms. For example, see http://www-01.ibm.com/support/docview.wss?uid=swg21231084.

keepalive-interval
TCP keepalive timeout interval in seconds. This is the time interval to wait between successive TCP keepalive probes
if there is no response to the previous probe. You can use this property with either a SQLFire client socket (to determine

when a server is offline) or a SQLFire network server socket (to determine when clients go offline). To use this property
