Hi , Your problem should be more specific. here I am giving 2 solutions. Pl. choose whichever is applicable. I. 1. comment the rollback segment in initsid.ora file. 2. connect internal 3. startup mount 4. Create rollback segment rbs02 with datafile rbs02.dbf(same as your earlier file) 5. alter database open II. 1. comment the rillback segment in initsid.ora file. 2. startup the database or explain your problem more clearly. rukmini - Original Message - To: Multiple recipients of list ORACLE-L [EMAIL PROTECTED] Sent: Tuesday, August 14, 2001 2:05 PM Hi gurus, Recently, I have forgotten to backup one of rollback segment file (rbs02.dbf).

Hermanto, some more information would be helpful -- why are you restoring? are you restoring from a cold or hot backup? if it was from a cold backup, you can comment out the rollback_segments parameter in the init.ora and start the database. Then I would drop the rollback tablespace and recreate it, with the rollback segments you want. Then change the init.ora and shutdown and restart the database Rachel From: Hermanto P [EMAIL PROTECTED] Reply-To: [EMAIL PROTECTED] To: Multiple recipients of list ORACLE-L [EMAIL PROTECTED] Subject: How can I get my DB back if I lost one of my rollback segment (rb Date: Tue, 14 Aug 2001 00:35:21 -0800 Hi gurus, Recently, I have forgotten to backup one of rollback segment file (rbs02.dbf).

You 'forgot' to backup a file? How are you taking backups? If a manual process. you should automate this before you forget to backup the SYSTEM tablespace.

Hermanto Rollback segment data files are *needed* for recovery. Rollback segments are the key component for consistent media/instance recovery. If you lose any of the rollback segment files and if any extents from that datafile are needed then the database can not do the recovery consistently and will give you errors. Is it the only data file associated with the rollback segment tablespace. If that is the case, there will be extents from the rollback segments. If there are no extents from the rollback segments then you could potentially offline drop the datafile, do the media recovery and do open resetlogs. What errors are you getting ? Stuck recovery ? Errors will tell you whether the recovery process is looking for rollback segments or the data file. Please contact Oracle support if there are any rollback extents in this datafile. _offline_rollback_segments and _corrupted_rollback_segments parameters can be used to hard open the database. But DO expect data consistency errors. In fact, only thing you should do is open this way, extract the data out and import in to a new database. Contact Oracle Support before you do this since there are serious consequences of doing this.

Re: How can I get my DB back if I lost one of my rollback segment (rb
Hi Recovery process will read from undo$ table to identify all the rollback segments that were online. Even if you comment out the rollback segments from the init file, still Oracle knows what rollback segments were online from the undo$ table. If i remember correctly, after reading the undo$ table, the process will read at least the rollback segment header and then only it proceed to open the database. If that rollback segment is not available, then you will not be able to open the database without using the underscore parameters. IMHO, Oracle support need to be contacted for further resolution..
