Feodor GeorgievSQL Server performance SQL Blog Here is the story: you wake up one morning, and as you read your email, you come across a SQL Server notification about "SQL Server Alert System: ‘Severity 021' occurred on Server1". Sounds bad. How bad sql autoclose is it? Do you panic? Not yet. Step 1: understand what the error means. After a event id 9001 group policy short consultation with the web you realize that the error is related to the corrupt or missing log file of the database, or a
Msg 9001, Level 21, State 1, Line 1
malfunctioning hard drive. Step 2. Is there a backup? NO?! Since the database log is not readable / accessible, it only makes sense that there is no backup, and since you delete the backups older than 2 days, the last working https://msdn.microsoft.com/en-us/library/cc645864.aspx backup of the database is gone. Do you panic now? A little. Step 3. Check the SQL Server error log for additional messages. All you find is "Error: 9001, Severity: 21, State: 1." and "The log for database ‘name_here' is not available. Check the event log for related error messages. Resolve any errors and restart the database." Cryptic, huh. Step 4. You try to backup the database. No go, it is expected. Step 5. You try to detach the database. You http://www.sqlservice.se/dont-panic-the-log-for-database-name_here-is-not-available/ know that SQL Server re-creates the log file if you try to attach an existing database and if you do not point to a specific log file. Good plan, but the detaching of the database does not work. The database is flagged as "not ready" and you cannot detach it. NOW do you panic? No, because you have a lot more tricks up your sleeve. Step 6. Query a table in the database. Ha! It works. The database is "not ready", but it is not "Suspect" yet. So, you can actually get the data out… Step 7. Right-click on the database, go to ‘Tasks' and then to ‘Copy Database'. The wizard starts, you follow it, and through it you create a SSIS package which helps you create a new database where all the data from the ‘not ready' database is extracted. Step 8. Drop the ‘not ready' database, rename the newly created one, move the files, sprinkle with sugar, bake for an hour and serve warm… 🙂 (yes, the last one was a "spur-of-the-moment-pure-daydreaming" 🙂 ) So, here is how you go around to fix the Error 9001, Severity: 21. Note that there is much more to do: check why the error occurred in the first place, check the hard drive integrity and so on. And remember: there is no single ultimate solution for a problem. Bottom line: If you would like to have automated email notifications from your SQL Server

I got a mail that the backup had failed, I opened the SQL log viewer and started browsing. And i found these two errors a bunch of times. error 1: Date 31-01-2013 error 9001 severity 13:20:30 Log SQL Server (Current - 01-02-2013 05:13:00) Source spid20s Message Error: 9001, Severity: 21, State: 1. error 2: Date 31-01-2013 13:20:30 Log SQL Server (Current - 01-02-2013 05:13:00) Source spid20s Message The log for database 'DB_NAME' is not available. Check the event log for related error messages. Resolve any errors and restart the database. After a little googling, I had read a few times that the errors indicated that the DB or log file maybe corrupt. I read that I could confirm it, by running a DBCC CHECKDB 'DB_NAME', so i did, and here are the last to lines of the output: CHECKDB found 0 allocation errors and 0 consistency errors in database 'DB_NAME'. DBCC execution completed. If DBCC printed error messages, contact your system administrator. The output shows that the DB isn't corrupt. But can the log file still be corrupt? I also read that one solution might be run something called "Emergency Mode Repair" to fix the corrupt files. But some users did NOT recommend it. Could another solution be to delete the log file completely and then create a new?. sql sql-server-2008-r2 backup logs share|improve this question asked Feb 4 '13 at 13:20 Arviddk 933310 closed as off-topic by Martin Smith, RolandoMySQLDBA, Marian, Michael - sqlbot, Erwin Brandstetter Dec
Check the event log for related error messages. Resolve any errors and restart the database. | Error: 9001, Severity: 21, State: 5. | Matched: %Error%, Posted on June 26, 2014 by john.dacosta Upon being greeted with the following logs, I started investigating the issue. I found the issue to be caused by the database being closed, and not any major underlying disk issue. Check if your database has auto_close enabled.
select @@SERVERNAME AS server_name,getutcdate() as report_date_utc,name as database_name, is_auto_close_on , state_desc, user_access_desc
from sys.databases
where is_auto_close_on = 1
order by name asc
If autoclose is on, switch this database to no longer use auto_close. Before making any changes, check the integrity of the database. If there are no errors generated by this command, then move on to changing the auto_close option.
dbcc checkdb('database_name')
alter database [database_name] set offline with rollback immediate;
go
alter database [database_name] set online;
alter database [database_name] set AUTO_CLOSE OFF;
