#modify_db_instance(options = {}) ⇒ Object

This API changes the settings of an existing DB Instance.

Changes are applied in the following manner: A ModifyDBInstance API call to modify security groups or to change the maintenance windows results in immediate action. Modification of the DB Parameter Group applies immediate parameters as soon as possible and pending-reboot parameters only when the RDS instance is rebooted. A request to scale the DB Instance class results puts the database instance into the modifying state.

The DB Instance must be in available or modifying state for this API to accept changes.

  • options (Hash) (defaults to: {}) —

    a customizable set of options

Options Hash (options):

  • :db_instance_identifier (String) — default: nil —

    the name of the db_instance

  • :master_user_password (String) —

    is the master password for the db instance (nil)

  • :port (String) —

    is the port the database accepts connections on (3306)

  • :db_name (String) —

    contains the name of the database to create when created (nil)

  • :db_parameter_group_name (String) —

    is the database parameter group to associate with this instance (nil)

  • :db_security_groups (Array) —

    are the list of db security groups to associate with the instance (nil)

  • :availability_zone (String) —

    is the availability_zone to create the instance in (nil)
