(URGENT) How to recover tablespace/datafile from an old backup ?

Hello,
I'm in charge of installation of IBM Websphere Commerce with an Oracle DB.
When I installed this software I do a "shutdown immediate" and copy all the files (data, ctl & redo) in an other directory a month ago.
I have some issues on a specific tablespace and I'd like to recover this tablespace so that my tablespace will be in the same state a month ago.
When I try "recover automatic tablespace data" Oracle restored and reload all the logs.
How can I restore with that old tablespace and find the content of september or is it possible to restore a tablespace without reload the redo logs ?
Thanks for any precious help.
Guillaume

If it was a complete set of files after shutdown immediate, you can mount that database on some other server with same structure and check the data in the tablespace. I dont see a need to load the old tablespace in the current database just to see some values.
By restoring the old tablespaces, you might even run into some referentials (if any) problem.

How to recover RSS feeds from Time Machine backup?

Hi,
I have deleted an RSS feed and so even his messages are gone. Then I have tried to recover it from my TM backup but I just discovered that TM shows me the RSS feed but it does not allow me to select them to recover.
Is it correct?
Is there any way to recover that?
thanks!

Thanks for the response BDAqua, I did use Migration Assistant to transfer her data from the SuperDuper backup. Are you suggesting that I use Migration Assistant to transfer data from the Time Machine backup? Will that result in duplication? Sorry, but I've no experience at all with Time Machine backups and don't know whether you can 'pick and choose' what to restore from the Time Machine using Migration Assistant.

How to recover Safari bookmarks from a previous backup?

Hello,
After about six months, I had to do a complete factory restore to resolve a nasty 3G connectivity problem. The restore to factory settings was a pain but it worked. Most of my apps have desktop versions to store crucial data files, but I forgot to save my Safari bookmarks. Is there any way I can selectively go to the past backup data files and find my bookmark links? I don't want to restore to a past backup in case it reintroduces the same problem that messed up my 3G connectivity, though I am tempted.
I tried opening some of the data backups in textedit but of course all I could see was code.
Thanks for any help.
Jim

No, a backup and restore is either all or nothing. You can't selecte what to backup or to restore.

My iPad broke but it was backed up.

I know the backup is there since I can see the folder and it is not empty:

How to recover a library from a laptop that doesn't work

My laptop died(my brother in law spilled cola on it). I have a new one but I don't know how to recover my library from the old one:( it doesn't start,the GeekSquad told me the motherboard is the problem(too expensive) but I can recover the library if I contact iTunes. So I was thinking to check the forum first,maybe somebody had the same problem.
Thank you

If you have everything on an iPod, you can get it back from that, too.
I don't know if I would trust the Geek Squad person who said contact itunes.
iTunes store support will not help you with hardware!
Maybe someone else on the squad could get your entire itunes folder off the hard drive.

8.3.4 Renaming a Datafile in the Primary Database
When you rename one or more datafiles in the primary database, the change is not propagated to the standby database. Therefore, if you want to rename the same datafiles on the standby database, you must manually make the equivalent modifications on the standby database because the modifications are not performed automatically, even if the STANDBY_FILE_MANAGEMENT initialization parameter is set to AUTO.
The following steps describe how to rename a datafile in the primary database and manually propagate the changes to the standby database.
   1.
      To rename the datafile in the primary database, take the tablespace offline:
      SQL> ALTER TABLESPACE tbs_4 OFFLINE;
   2.
      Exit from the SQL prompt and issue an operating system command, such as the following UNIX mv command, to rename the datafile on the primary system:
      % mv /disk1/oracle/oradata/payroll/tbs_4.dbf
      /disk1/oracle/oradata/payroll/tbs_x.dbf
   3.
      Rename the datafile in the primary database and bring the tablespace back online:
      SQL> ALTER TABLESPACE tbs_4 RENAME DATAFILE      2> '/disk1/oracle/oradata/payroll/tbs_4.dbf'
        3> TO '/disk1/oracle/oradata/payroll/tbs_x.dbf';
      SQL> ALTER TABLESPACE tbs_4 ONLINE;
   4.
      Connect to the standby database, query the V$ARCHIVED_LOG view to verify all of the archived redo log files are applied, and then stop Redo Apply:
      SQL> SELECT SEQUENCE#,APPLIED FROM V$ARCHIVED_LOG ORDER BY SEQUENCE#;
      SEQUENCE# APP
      8 YES
      9 YES
      10 YES
      11 YES
      4 rows selected.
      SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL;
   5.
      Shut down the standby database:
      SQL> SHUTDOWN;
   6.
      Rename the datafile at the standby site using an operating system command, such as the UNIX mv command:
      % mv /disk1/oracle/oradata/payroll/tbs_4.dbf /disk1/oracle/oradata/payroll/tbs_x.dbf
   7.
      Start and mount the standby database:
      SQL> STARTUP MOUNT;
   8.
      Rename the datafile in the standby control file. Note that the STANDBY_FILE_MANAGEMENT initialization parameter must be set to MANUAL.
      SQL> ALTER DATABASE RENAME FILE '/disk1/oracle/oradata/payroll/tbs_4.dbf'
        2> TO '/disk1/oracle/oradata/payroll/tbs_x.dbf';
   9.
      On the standby database, restart Redo Apply:
      SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE
        2> DISCONNECT FROM SESSION;
If you do not rename the corresponding datafile at the standby system, and then try to refresh the standby database control file, the standby database will attempt to use the renamed datafile, but it will not find it. Consequently, you will see error messages similar to the following in the alert log:
ORA-00283: recovery session canceled due to errors
ORA-01157: cannot identify/lock datafile 4 - see DBWR trace file
ORA-01110: datafile 4: '/Disk1/oracle/oradata/payroll/tbs_x.dbf'Hope That Helps.

How to recover system datafile???

Hello,
Do you guys have any idea how to recover SYSTEM datafile if the datafile is missing and it's not being back up ?
suhaimi
[email protected]

Dear Suhaimi,
The only possible way of recovering the SYSTEM tablespace (and its datafiles) is from the Hot or Cold backups taken earlier. For ensure complete recoverability, I advise you to run your database in ARCHIVELOG mode and take regular online backups.
Ciao!
