RE: RENAME DATAFILE
Seema, It is not a risky process. The proper way to do it is: Alter tablespace {name} offline; ! host copy filename to newlocation; Alter database rename file 'oldname' to 'newname'; alter tablespace {name} online; * backup your database! * if all goes well, remove the old file. You obviously need to be able to take the tablespace offline to do this, so no queries or transactions may be running while you do this. You also need to perform a backup (at least alter database backup controlfile to trace). Hope this helps.

Re: Rename Datafile
Dear DBAs Question about alter database rename file '/oldlocation/datafile1' to '/newlocation/datafile1'; This command ususal to move a datafile to a new location. In case of rename file, I mean here '/oldlocation/datafile1' to '/newlocation/newdatafilename'; or '/oldlocation/datafile1' to '/oldlocation/newdatafilename'; I have never seen anybook mention this I guess step is 1. shutdown database (normal or immediate) 2. cp /oldlocation/datafile1 /newlocation/newdatafilename or mv /oldlocation/datafile1 /oldlocation/newdatafilename 3. startup restirct mount; 3 alter database rename file '/oldlocation/datafile1' to '/newlocation/newdatafilename'; or '/oldlocation/datafile1' to '/oldlocation/newdatafilename'; 4. check status of v$datafile 5. restart database Any suggestiion?

Re: Rename Datafile
Hi Mitchell, The steps should work. Oracle recommends to shutdown the mounted database before opening again after the change(I am not sure about if this is required) I would just open the closed db. I usually, a.Backup the database(going to do a structural change!) b.Take the tablespace connected to the tablespaceoffline if the datafiles belong to non system t/s(it would be better to shutown , start and mount if it is in Production !) c.copy the datafiles to the new location and rename using o/s commands. d.Rename the datafiles in Oracle using alter tablespace t/s name rename datafile 'old file ' to 'new file' e.bring the tablespace online or shutdown and restart the db or iopen the mounted dbas the case may be. f.Full Backup db again with the new structure.

RE: Rename Datafile
You do not need to shut the database. Only take the tablespace offline where the datafiles are reorganized.

RE: Rename Datafile
Why not to make tablespace offline, rename datafile in oracle and them use unix mv command to move it? Copy is not good ig there is no space.

RE: Rename Datafile
Title: RE: Rename Datafile -Original Message- From: Thater, William [mailto:[EMAIL PROTECTED]] On Mon, 7 May 2001,Hillman, Alex scribbled on the wall in glitter crayon: -Why not to make tablespace offline, rename datafile in oracle and them use -unix mv command to move it? Copy is not good ig there is no space. Well, the time I tried it, ORACLE didn't like the fact the new file wasn't there first. But that was in version 7.3.2 so maybe in 8x that would work. I have taken the tablespace offline, renamed the datafile in the OS, after the OS rename used 'alter database rename file' in SQL*Plus, then successfully brought the tablespace back online. This was in Oracle 8.0, 8.1 on SunOS and Windows NT/2000. -- Jacques R. Kilchoer (949) 754-8816 Quest Software, Inc. 8001 Irvine Center Drive Irvine, California 92618 U.S.A. http://www.quest.com
