/**
 * <p>Changes the audit policy state of a database activity stream to either locked (default) or unlocked. A locked policy is read-only, whereas an unlocked policy is read/write. If your activity stream is started and locked, you can unlock it, customize your audit policy, and then lock your activity stream. Restarting the activity stream isn't required. For more information, see <a href="https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/DBActivityStreams.Modifying.html"> Modifying a database activity stream</a> in the <i>Amazon RDS User Guide</i>. </p> <p>This operation is supported for RDS for Oracle and Microsoft SQL Server.</p>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { RDSClient, ModifyActivityStreamCommand } from "@aws-sdk/client-rds"; // ES Modules import
 * // const { RDSClient, ModifyActivityStreamCommand } = require("@aws-sdk/client-rds"); // CommonJS import
 * // import type { RDSClientConfig } from "@aws-sdk/client-rds";
 * const config = {}; // type is RDSClientConfig
 * const client = new RDSClient(config);
 * const input = { // ModifyActivityStreamRequest
 *   ResourceArn: "STRING_VALUE",
 *   AuditPolicyState: "locked" || "unlocked",
 * };
 * const command = new ModifyActivityStreamCommand(input);
 * const response = await client.send(command);
 * // { // ModifyActivityStreamResponse
 * //   KmsKeyId: "STRING_VALUE",
 * //   KinesisStreamName: "STRING_VALUE",
 * //   Status: "stopped" || "starting" || "started" || "stopping",
 * //   Mode: "sync" || "async",
 * //   EngineNativeAuditFieldsIncluded: true || false,
 * //   PolicyStatus: "locked" || "unlocked" || "locking-policy" || "unlocking-policy",
 * // };
 *
 * ```
