Parameter: grouptimeout

Startup parameters change the behavior of the Service Manager server. You can always set a startup parameter from the server's operating system command prompt.

Parameter

grouptimeout

Description

This parameter allows you to configure the timeout value (in milliseconds) for Jgroups remote procedure calls. You can tune this value to keep the number of available nodes stable.

It is recommended to set this parameter to a minimal value as long as it can keep the number of the available nodes stable. Meanwhile, the network latency between the web server and the Service Manager server should be small, otherwise the load balancer may forward a request to a node that is not able to handle the request due to network latency.
