EnableSharding

Enable the sharding service for this instance.

Synopsis

[Startup]    EnableSharding=n

n is either 1 (true) or 0 (false).

Description

When this parameter is enabled (n = 1), InterSystems IRIS® data platform enables the Sharding service (%Service_Sharding) during instance startup. When EnableSharding is disabled (n = 0), %Service_Sharding is unchanged during instance startup. This means EnableSharding can only be used to enable the Sharding service, not to disable it.

EnableSharding is not in the default CPF, but can be included as a parameter in a CPF merge file. To directly enable %Service_Sharding without the EnableSharding parameter, use the Services page of the Management Portal (System Administration > Security > Services).

Changing This Parameter

EnableSharding is not in the default CPF. You can manually add this parameter to the [Startup] section of the CPF using a text editor (as described in the Editing the Active CPF section of the “Introduction to the Configuration Parameter File” chapter in this book).

After adding EnableSharding and restarting InterSystems IRIS, you can change the parameter using a text editor, the Config.Startup class (as described in the class reference), or the Startup page of the Management Portal (System Administration > Configuration > Additional Settings > Startup).
