My SQL Server database is showing as "recovering".

A. Every time SQL Server starts up it recovers all databases so that all transactions are either committed or rolled-back. This recovery process normally only takes a few seconds/minutes, but if the server was terminated in the middle of a long running update, then the recovery can take at least as long as the update had taken so far - sometimes longer due to the extra contention on the log device (when writing the original updates to the log these are all written sequentially to the end. When recovery occurs SQL has to scan through the log looking for these updates as well as committing new updates that might be occurring on other databases).

Give it plenty of time to recover, but at the same time check the current and previous errorlog files, and NT errorlogs, for any indications of what has happened. If you've hit a hardware problem or SQL bug, then there WILL be errors there to give an indication on what happened.  (See also, "I'm getting an error 603 on database recovery in a SQL 6.0 system").

Check the physical disk activity lights on the server, and also check the sysprocesses activity to see if the recovery task is using cpu and/or disk i/o. Only on very rare occasions will SQL Server not recover the database correctly.

Additionally, to check on recovery progress you could set trace flag 3412 which writes an entry to the errorlog when each transaction is rolled forward or back.

If a database will not recover and you do NOT have a backup then you can use the following trace flags to bypass recovery. If you use these then the database/data may not be in a consistent state, but if you have no other choice then use them and then immediately transfer out (using bcp or transfer tools) all the objects you require.

3607 Skips automatic recovery for all databases.
3608 Skips automatic recovery for all databases except the master database.

If the database is still unavailable - marked as suspect - then issue the following command to put the database into emergency mode (you'll need to allow updates first). You can then go into the database (no need to restart SQL) and extract out the data.

UPDATE master..sysdatabases SET status=-32768 WHERE name='<dbname>'

If all else fails, or you are unsure what to do, then don't hesitate to place a call with Microsoft Product Support Services (PSS). They are there 24x7x365 to deal with problems like this and the charge is nominal compared to the loss of your data! (More details on Microsoft PSS in the mspss.txt faq entry)
