You can call this operation to modify the parameters of an AsparaDB for MongoDB instance.

The instance must be in the running state when you call this operation.

Note If some of the modified parameters take effect only after the instance is restarted, the instance is automatically restarted after the operation is complete. You can call the DescribeParameterTemplates operation to query the parameters that take effect only after the instance is restarted.
