Set the maximum number of connections from ECP clients.


[config]    MaxServerConn=n

n is an integer in the range 0—254. The default value is 1.


MaxServerConn is the maximum number of ECP clients that can access this instance simultaneously. This is the maximum number of connections that this instance may accept when acting as an ECP server. If you modify this setting, you must restart the instance for the change to take effect.

When an instance is a member of a sharded cluster, this setting must be equal to or greater than the number of nodes in the cluster. For more information, see Configure or Deploy a Cluster Using CPF Settings in the “Horizontally Scaling for Data Volume with Sharding” chapter in the Scalability Guide.

Changing This Parameter

On the Advanced Memory page of the Management Portal (System Administration > Configuration > Additional Settings > Advanced Memory), in the MaxServerConn row, select Edit. Enter a value.

You can also change this parameter on the ECP Settings page of the Management Portal (System Administration > Configuration > Connectivity > ECP Settings). In the This System as an ECP Data Server column, edit Maximum number of application servers.

Instead of using the Management Portal, you can change MaxServerConn in the Config.configOpens in a new tab class (as described in the class reference) or by editing the CPF in a text editor (as described in the Editing the Active CPF section of the “Introduction to the Configuration Parameter File” chapter in this book).
