I did, Execute the Alter Datafile query

i got outut - the files are moved . next time when DB starts..

Fine enough..then i took the DB to OFfline state..

Now i am trying to copy the Old datafiles to the new location which i have set...

But error -

Access Denied, File may be currently in use :w00t:

i have admin rights on the drives & folders.. & nothing is open still its not allowing me to copy the files :w00t:

Hiya,

Taking the Database Offline isn't good enough, this stops the database from being accessed but SQL Server is still accessing the file. You need to stop the SQL Server Service then move the files then start the SQL Server service again.

if your database is still accessible, then you have one more option to move your database files,

1)take the backup of the DB

2)Restore on the same server with different name and log file on different drive than data file with norecovery .

3)make sure that no user is connected to DB , and then take log backup and append it on newly created DB with recovery

4)Change old DB name , change the new DB name to original DB name .

I hope thats not much confusing,it will also minimize your downtime

Verify the ACLs on the folder, being an admin on the server does not gurantee that you can access the files if the ACLs have been changed. Right click the folder and select properties, then click the security tab.

Taking the Database Offline isn't good enough,

Taking the database offline will allow you to copy, move or even delete the database files, it's my guess there are ACLs stopping the user copying the file.

Runal,

See my post, above sanket's.The document I provided you does say you need to stop the SQL Server service before moving the physical files.

Taking the Database Offline only makes the Database inaccessible. SQL Server will still have a lock on the physical file.

So...

1.) Stop the SQL Server Service.

2.) Move the physical files.

3.) Start the SQL Server Service.

Regards

Paul

No it doesn't! This is an action I have performed more times than I care to remember, offlining the database will release any hold the engine had on the files, you may then copy move or even delete them!
