Parameter: groupname

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

groupname

Description

This parameter creates a virtual group that servlet container processes across multiple systems can join for horizontal scaling purposes. Systems that list the same virtual group name are part of the same group. This parameter requires the use of the groupmcastaddress and groupport parameters to define the resources group members can use to talk to the load balancer process.

It is best practice to place this parameter in the Service Manager initialization file so that all servlet container processes started on the same host share the virtual group name specified by this parameter.
