Hi

I'm trying to delete a tablespace and get the following error:

ORA-01156: recovery in progress may need access to files

When I look at the data files of the tablespace they have status "RECOVER" although there is no recovery running.

Is there a way to reset the status of these files so they can be deleted?

Thanks in advance
Martin

Did you manually remove the files from the filesystem already?

What does the ERROR column indicate in V$RECOVER_FILE ?

Have you tried to run:

ALTER TABLESPACE <tablespace_name> OFFLINE IMMEDIATE;

I did remove the files manually but only after not being able to delete them by the enterprise manager.

The error column in v$recover_file is empty although the view has a row for each file.

The "alter tablespace" command was successful but the situation is unchanged.

We managed to drop the tablespaces by setting the database in NOARCHIVELOG mode. But as soon as we're setting it back to ARCHIVELOG we can't delete any tablespaces anymore having the same error 01156. But no more files in RECOVER state are present! In fact we can create a new tablespace without any data in it and can't delete it. Setting it offline and online again works fine.

We found out, that there is always one ARCH process more then the configured maximum. If we set the max to 2 we have 3 processes running. Killing them does not help as they are restarted immediately. Any ideas?

We solved the problem. The cause was a log process belonging to an already removed standby instance. The process was still running and supposedly still trying to synchronize instances. When removing the standby instance it was not uninstalled correctly.
