setClusterParameter (database command)

Definition

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.

Compatibility

This command is available in deployments hosted in the following environments:

MongoDB Enterprise: The subscription-based, self-managed version of MongoDB
MongoDB Community: The source-available, free-to-use, and self-managed version of MongoDB

Important

This command is not supported in MongoDB Atlas clusters. For information on Atlas support for all commands, see Unsupported Commands.

Syntax

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

For the available cluster parameters, including examples, see Cluster Parameters for a Self-Managed Deployment.

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.
setClusterParameter accepts only one parameter at a time.

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.
