Re: Sanity Check Please: Removing Datafiles after Dropping Tablespace?

Hey there,

Some things you may want to try before deleting them:

• If Linux, run lsof (lsof | grep filename) to check if the database still has these files open
• Check the date/time stamp. If timestamps are current, the file(s) are still being used
• if you're still unsure, rename/compress the files. This way if files are still needed, you can 'restore' them by renaming/uncompressing them

hth,

Todd
