Among database management systems, Microsoft SQL Server 2019 is the first choice of many organizations and developers due to its powerful performance and advanced features. However, in the process of using it, you may encounter various problems, such as services failing to start, databases in a suspect mode, or the need to recover from a failure. This article aims to provide some practical ways to help you how to repair SQL Server 2019 to ensure data integrity and system stability.
How to Fix SQL Server 2019: Service Startup Failure
When you encounter the “The service did not respond to the start or control request in a timely fashion. Click ‘Retry’ to retry the failed action, or click ‘Cancel’ to cancel this action and continue setup.” error while installing or configuring SQL Server 2019, you can try the following steps to fix it:
Check system time synchronization: Ensure that your system time is synchronized with the network time server. Inaccurate system time may cause SQL Server service startup failure. You can manually synchronize the time by running a command prompt and entering the w32tm /resync command.
Service Dependency check: Ensure that all SQL Server related services (such as SQL Server Service, SQL Server Agent, SQL Server Browser, etc.) are installed and set to start automatically, and check whether the dependencies between these services are configured correctly.
Check the Event Viewer: Find detailed error messages about service startup failures through the Event Viewer, which can help to locate the root cause of the problem.
How to Repair SQL Server 2019: Database in Suspect Mode
A database going into a suspect mode is usually caused by an abnormal shutdown, hardware failure, or corrupted transaction logs. Steps to repair SQL Server mode in suspect mode include:
Attempt automatic repair: First try to restart the SQL Server service, sometimes the system will automatically try to repair the database.
Use emergency mode: If automatic repair does not work, you can set the database to emergency mode to allow access. This usually requires editing the SQL Server startup parameters directly to add the -f flag to start the SQL Server instance.
DBCC CHECKDB: Once the database is accessible, run the DBCC CHECKDB command to check the logical and physical consistency of the database and repair it based on the output recommendations.
Backup and restore: Before any repair operation, restoring the database from a recent full backup, if possible, is the safest solution. Ensure regular database backups to avoid data loss.
