OVD parameter vde.soTimeoutBackend to keep alive functionality

while tuning OVD connection to OID, please read below in order to troubleshoot performance issues that can occur at OVD side.


vde.soTimeoutBackend is defined in OVD to keep track of inactivity period. without this parameter setting OVD will response slower because it uses the inactive connection to talk to OID(or any LDAP server) and it has to wait to get the information about the inactive connection.
this parameter is present in OVD by default and it closes the inactive connection after the time specified by this parameter. in order to use this OS keep-alive needs to be enabled because it depends on the value of OS setting.


below is another parameter to consider

<socketOptions>… 
<keepAlive>false</keepAlive> 
... 
</socketOptions> 

Turn off keepAlive. This parameter is only required to ensure that there is a tcp keep alive sent to the client to make sure that the connection opened by the client to OVD is still valid. On Linux OS, the timing of this keepAlive parameter is controlled by the OS parameter net.ipv4.tcp_keepalive_time in second.

if you want OS to handle keep-alive setting than disabled this parameter
