What does it mean SQL Server shows database in recovery?

739    Asked by Ankesh Kumar in SQL Server , Asked on Sep 4, 2021
Today, after a power failure, one database (with Recovery: full) shows "In Recovery" in SSMS. So: myDatabase (In recovery) (database status: recovery, Shutdown)
After finish, the "recovery process" the database shows the name myDatabase without "(In recovery)". I thought that the problem was solved, but it was not.
When I started the application that uses that database, the extra text "(In recovery)" appears again next to the name of my database.
I waited until the "recovery process" finished and then I took the database offline and brought it back online.

I restarted the server, restarted the computer and when my application was running the extra text appears again. In the SQL Server logs the message "Starting up database 'myDatabase'" appears few times. It seems that the database is working because I can insert data, but the state is showing that something it happens. The server log is not showing anything interesting. The only abnormal thing is that I have 30 entries of "Starting up database 'myDatabase'". I know that when the server starts every database goes through recovery before it is ready for use. But in my case, the database comes online then shows "myDatabase (In recovery)". If I close the application, the database goes to Status: Normal. This is driving me crazy. I've even installed a new instance of SQL Server, and put the old database "myDatabase" on it. The problem still happens. When I run this query: SELECT databasepropertyex('nyDatabase', 'STATUS') It shows recovering, online, suspect and the back to online and then recovering and so on. What does it mean when a SQL database in recovery?

  After restarting SQL Server, the database moves to “In Recovery” mode. You may also see the DB in recovery state on its startup or when restoring it from backup. The database 'recovering' state means that the database performs a recovery process and will automatically come online once the process is complete.

Whenever you bring a database online, it goes through a recovery process. I'm a bit confused by your phrasing of the problem though. Are you seeing the database go into recovery any time other than when the database is being brought offline (either from your original power failure or by your having brought it offline and then online again)? If so, the database is going offline for some other reason. Best to check the SQL server logs to see what's going on. You should also check the Windows event log for something like a disk failure. The database should not be starting up and going into recovery during normal operations.
