<p>The weekly time range (in UTC) during which system maintenance can occur, which might result in an outage. Changing this parameter doesn't result in an outage, except in the following situation, and the change is asynchronously applied as soon as possible. If there are pending actions that cause a reboot, and the maintenance window is changed to include the current time, then changing this parameter will cause a reboot of the DB instance. If moving this window to the current time, there must be at least 30 minutes between the current time and end of the window to ensure pending changes are applied.</p> <p>For more information, see <a href="https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_UpgradeDBInstance.Maintenance.html#Concepts.DBMaintenance">Amazon RDS Maintenance Window</a> in the <i>Amazon RDS User Guide.</i> </p> <p>Default: Uses existing setting</p> <p>Format: ddd:hh24:mi-ddd:hh24:mi</p> <p>Valid Days: Mon | Tue | Wed | Thu | Fri | Sat | Sun</p> <p>Constraints: Must be at least 30 minutes</p>

<p>The version number of the database engine to upgrade to. Changing this parameter results in an outage and the change is applied during the next maintenance window unless the <code>ApplyImmediately</code> parameter is enabled for this request.</p> <p>For major version upgrades, if a nondefault DB parameter group is currently in use, a new DB parameter group in the DB parameter group family for the new engine version must be specified. The new DB parameter group can be the default for that DB parameter group family.</p> <p>If you specify only a major version, Amazon RDS will update the DB instance to the default minor version if the current minor version is lower. For information about valid engine versions, see <code>CreateDBInstance</code>, or call <code>DescribeDBEngineVersions</code>.</p> <p>If the instance that you're modifying is acting as a read replica, the engine version that you specify must be the same or later than the version that the source DB instance or cluster is running.</p> <p>In RDS Custom for Oracle, this parameter is supported for read replicas only if they are in the <code>PATCH_DB_FAILURE</code> lifecycle.</p>

<p>A value that indicates whether major version upgrades are allowed. Changing this parameter doesn't result in an outage and the change is asynchronously applied as soon as possible.</p> <p>This setting doesn't apply to RDS Custom.</p> <p>Constraints: Major version upgrades must be allowed when specifying a value for the EngineVersion parameter that is a different major version than the DB instance's current version.</p>

<p>A value that indicates whether minor version upgrades are applied automatically to the DB instance during the maintenance window. An outage occurs when all the following conditions are met:</p> <ul> <li> <p>The automatic upgrade is enabled for the maintenance window.</p> </li> <li> <p>A newer minor version is available.</p> </li> <li> <p>RDS has enabled automatic patching for the engine version.</p> </li> </ul> <p>If any of the preceding conditions isn't met, RDS applies the change as soon as possible and doesn't cause an outage.</p> <p>For an RDS Custom DB instance, set <code>AutoMinorVersionUpgrade</code> to <code>false</code>. Otherwise, the operation returns an error.</p>

<p>The new Provisioned IOPS (I/O operations per second) value for the RDS instance.</p> <p>Changing this setting doesn't result in an outage and the change is applied during the next maintenance window unless the <code>ApplyImmediately</code> parameter is enabled for this request. If you are migrating from Provisioned IOPS to standard storage, set this value to 0. The DB instance will require a reboot for the change in storage type to take effect.</p> <p>If you choose to migrate your DB instance from using standard storage to using Provisioned IOPS, or from using Provisioned IOPS to using standard storage, the process can take time. The duration of the migration depends on several factors such as database load, storage size, storage type (standard or Provisioned IOPS), amount of IOPS provisioned (if any), and the number of prior scale storage operations. Typical migration times are under 24 hours, but the process can take up to several days in some cases. During the migration, the DB instance is available for use, but might experience performance degradation. While the migration takes place, nightly backups for the instance are suspended. No other Amazon RDS operations can take place for the instance, including modifying the instance, rebooting the instance, deleting the instance, creating a read replica for the instance, and creating a DB snapshot of the instance.</p> <p>Constraints: For MariaDB, MySQL, Oracle, and PostgreSQL, the value supplied must be at least 10% greater than the current value.

<p>A value that indicates whether to manage the master user password with Amazon Web Services Secrets Manager.</p> <p>If the DB cluster doesn't manage the master user password with Amazon Web Services Secrets Manager, you can turn on this management. In this case, you can't specify <code>MasterUserPassword</code>.</p> <p>If the DB cluster already manages the master user password with Amazon Web Services Secrets Manager, and you specify that the master user password is not managed with Amazon Web Services Secrets Manager, then you must specify <code>MasterUserPassword</code>. In this case, RDS deletes the secret and uses the new password for the master user specified by <code>MasterUserPassword</code>.</p> <p>For more information, see <a href="https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/rds-secrets-manager.html">Password management with Amazon Web Services Secrets Manager</a> in the <i>Amazon RDS User Guide.</i> </p> <p>Constraints:</p> <ul> <li> <p>Can't manage the master user password with Amazon Web Services Secrets Manager if <code>MasterUserPassword</code> is specified.</p> </li> </ul>

<p>A value that indicates whether to rotate the secret managed by Amazon Web Services Secrets Manager for the master user password.</p> <p>This setting is valid only if the master user password is managed by RDS in Amazon Web Services Secrets Manager for the DB cluster. The secret value contains the updated password.</p> <p>For more information, see <a href="https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/rds-secrets-manager.html">Password management with Amazon Web Services Secrets Manager</a> in the <i>Amazon RDS User Guide.</i> </p> <p>Constraints:</p> <ul> <li> <p>You must apply the change immediately when rotating the master user password.</p> </li> </ul>

<p>The Amazon Web Services KMS key identifier to encrypt a secret that is automatically generated and managed in Amazon Web Services Secrets Manager.</p> <p>This setting is valid only if both of the following conditions are met:</p> <ul> <li> <p>The DB instance doesn't manage the master user password in Amazon Web Services Secrets Manager.</p> <p>If the DB instance already manages the master user password in Amazon Web Services Secrets Manager, you can't change the KMS key used to encrypt the secret.</p> </li> <li> <p>You are turning on <code>ManageMasterUserPassword</code> to manage the master user password in Amazon Web Services Secrets Manager.</p> <p>If you are turning on <code>ManageMasterUserPassword</code> and don't specify <code>MasterUserSecretKmsKeyId</code>, then the <code>aws/secretsmanager</code> KMS key is used to encrypt the secret. If the secret is in a different Amazon Web Services account, then you can't use the <code>aws/secretsmanager</code> KMS key to encrypt the secret, and you must use a customer managed KMS key.</p> </li> </ul> <p>The Amazon Web Services KMS key identifier is the key ARN, key ID, alias ARN, or alias name for the KMS key. To use a KMS key in a different Amazon Web Services account, specify the key ARN or alias ARN.</p> <p>There is a default KMS key for your Amazon Web Services account. Your Amazon Web Services account has a different default KMS key for each Amazon Web Services Region.</p>
