    Operation description

    This operation creates a recent deadlock analysis task. Database Autonomy Service (DAS) analyzes the most recent deadlock log returned by SHOW ENGINE INNODB STATUS. If multiple deadlocks have occurred, DAS analyzes only the most recent one. For more information, see Recent deadlock analysis.

    Before you begin, make sure the following prerequisites are met:

    • The database engine is one of the following: ApsaraDB RDS for MySQL, self-managed MySQL, PolarDB for MySQL, or PolarDB-X 2.0.

    • If you use the China site (Chinese) or DAS SDK, use the latest version.

    • When you call DAS by using the SDK, set the region to cn-shanghai.

    Try this API in OpenAPI Explorer, no manual signing needed. Successful calls auto-generate SDK code matching your parameters. Download it with built-in credential security for local usage.

    RAM authorization

    The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

    • Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.

    • API: The API that you can call to perform the action.

    • Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.

    • Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.

      • For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.

      • For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.

    • Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.

    • Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.
