setClusterParameter¶

setClusterParameter is an administrative command for modifying values of cluster parameters. Cluster parameters are configurable parameters which affect all nodes in a replica set or sharded cluster.

You must issue the setClusterParameter command against the admin database.

Syntax¶

copy

db.adminCommand( { setClusterParameter: { <parameter>: <value> } } )

For the available cluster parameters, including examples, see <cluster-parameters>.

Behavior¶

You can only run setClusterParameter on the admin database. If you run the command on any other database, MongoDB returns an error.
You can only run setClusterParameter on a replica set primary or on a sharded cluster.
You cannot run setClusterParameter on a standalone deployment.

Accesss Control¶

When authentication is enabled, setClusterParameter only works when authenticated as a user with a role that has access to the setClusterParameter action.

Persistence¶

The parameter modifications made using setClusterParameter are persisted on replica sets and sharded clusters. This ensures that parameter modifications made using setClusterParameter survive restarts.

Stable API¶

When using Stable API V1 with apiStrict set to true, you cannot use setClusterParameter to modify cluster parameters.
