SQL Server: 置空梦想，重新出发（sqlserver置空）

SQL Server：Resetting Dreams and Starting afresh

As an experienced database administrator, I have seen a lot of unexpected situations in my line of work. One of the most devastating was when all of the data stored on one of my SQL Servers was wiped clean from an unexpected power outage. I was left with nothing, the feeling of helplessness rapidly eating away at the dreams and aspirations I had for my database for months.

However, this was not the end, I had to start over. With each step taken, I was determined to not repeat the mistakes I had made previously and I was faced with a daunting task of configuring the database from scratch. There was a long process of reinstalling the software, setting up configurations and recreating the necessary user accounts.

But I wasn’t alone in this process, I had help. I was lucky enough to find a few resources that had been crafted precisely for this situation. A quick search directed me to a technet article that discussed a step-by-step procedure to reset a SQL Server instance to its original configuration settings. Following the guide, I built a script to help reset the settings, as follows:

USE [master] GO

EXEC dbo.sp_configure N’reset all settings’, N’ 1′ GO

RECONFIGURE WITH OVERRIDE GO

GO

To reinstate the security settings, I had to recreate user accounts and set detailed permissions. I found another technet article describing a method to generate a SQL script to generate create user statements that are based on existing user settings. This script ran on one of the SQL Servers, which was then saved to a network drive. From there, I had to run the script on any other affected servers and re-create the user settings.

After all the settings and user accounts had been restored, I was faced with one final task of restoring the data. Fortunately I had a backup that I had taken prior to the power outage, which I could use to undo the damage. The backup was verified and the data was restored using the “restore database” command.

After going through this long process, the database was finally functioning at its original capacity. I was relieved and proud of the progress I had made in the process. It was a learning experience that taught me a valuable lesson – that when it comes to SQL Server, there is no such thing as giving up. When faced with a challenging reset request, it is possible to get back on track and rebuild the data.

Through this experience, I was also reminded of the importance of making regular backups of the data. Now, I make sure to back up the data on a weekly basis, so I can be prepared for any future unexpected power outages or system failure.

To conclude, SQL Server resetting is something that requires the proper understanding of the system and knowledge of specific commands and scripts. By keeping in mind the best practices of backup and recovery, it is possible to reset a SQL Server instance without too much difficulty.
