From the Database options section, for DB parameter group, choose the parameter group you created.ĭB instances require a manual reboot in the following circumstances:.In the DB identifier section, choose your RDS DB instance.In the navigation pane, choose Databases.Choose Edit parameters, and select 12.On the Parameter groups page, choose the group that you created in the previous step.For Parameter group family, choose the SQL Server version and edition you are using.įor example, SQL Server 2017 Standard Edition uses sqlserver-se-14.0.On the Amazon RDS console, choose Parameter groups in the navigation pane.

To enable deadlock detection, complete the following steps.

An email address to receive notificationsĮnable deadlock detection for Amazon RDS for SQL Server.

Access to the AWS Management Console and Amazon CloudWatch.

Monitor the solution using Amazon RDS Performance Insights.

Create a filter pattern and CloudWatch alarm.

Publish the SQL Server error logs to CloudWatch.

Enable deadlock detection for Amazon RDS for SQL Server.

To implement the solution, we walk through the following high-level steps: The following diagram illustrates the solution architecture.

In this post, we show you how to publish error and agent log events directly to Amazon CloudWatch Logs and set up CloudWatch alarms and SNS notifications for the deadlock events that match the filter pattern that you create.

This solution isn’t limited to capturing deadlock events you can scale this solution to monitor other system and user-defined events captured in the error logs and SQL Server agent logs. This can help you automate deadlock reporting and take appropriate actions to resolve deadlock conflicts. With Amazon Relational Database Service (Amazon RDS) for SQL Server, you can now monitor the deadlocks and send Amazon Simple Notification Service (Amazon SNS) notifications as soon as a deadlock event occurs on an RDS for SQL Server instance. Transaction (Process ID xx) was deadlocked on resources with another processĪnd has been chosen as the deadlock victim. The error message that SQL Server sends back to the client is similar to the following:

When this situation occurs, there is no way for these processes to resolve the conflict, so SQL Server automatically chooses one of the processes as the victim of the deadlock and rolls back the process, and the other process succeeds.īy default, when this occurs, your application may see or handle the error, but nothing is captured in the SQL Server error log or the Windows event log to let you know this occurred. A deadlock occurs when two or more processes are waiting on the same resource and each process is waiting on the other process to complete before moving forward. SQL Server logs these events in SQL Server error logs and SQL Server agent logs.ĭeadlocks are one such event can be captured in SQL Server error logs. Many of our customers want to capture certain systems and user-defined events for monitoring and troubleshooting problems related to SQL Server. Monitoring SQL Server is an essential aspect of any relational database management system (RDBMS) when dealing with performance problems.
