Is the tablespace actually off-line when doing a user-managed hot backup? I know the data blocks are copied into a redo stream but I am not sure if that means it(tablespace) is actually on-line or off-line.
View 6 RepliesI have a 10G Express system running. I Have 2 tablespaces in production. WHen taking backup, it terminates unsuccessfully saying system01.dbf is damaged. The application works fine and no data loss is found through the application interface.
So can I shift the data to a new server using the dbf files of the tablespaces in use?
I'm rying to import schema's from a dump file that came from a different environment.
What I have is:
1. dump file
2. log file of the export
I'm trying to import the file(containing three schemas) with remap_schemas, and it fails, gives a lot of ORA-00959: tablespace 'string' does not exist.
Now, I've read in OTN:
[URL]
that what you need to do in that case is to use the REMAP_TABLESPACE option,to redirect the objects to a different tablespace.
I don't see a name of the tablespace I'm getting the error for in the export log.I don't know if I have more tablespaces I have to redirect with REMAP_TABLESPACE.
I don't want to perform this 3 times, have an error, by that find out what's the next tablespace needing redirection and only then starting over...
How can I know from the dump file and the log file,what is the tablespace names i need for the redirection to my names? Or its just that the tablespace giving me the error is the only one in the dump file?

We are doing daily cold backup. Due to lack of disk space,we couldn't Hot backup. We want our database to be up when doing backups. Since only export/import is possible in our scenario, clarify few queries:
1) Export was done during off period from the live server.
2) We have a development server, in which we have to update our database daily. Can i overwrite the Development server using IMPORT daily? Since this import might show lots of errors (Object already exist), what parameters can i use for import.
why datapump is faster than normal exp ? one ans that i know is dp use block mode and exp use byte mode . is there any other major reason? if say i have database of size 10g and want to take datapump backup, but condition is that i can take dumpfile of size 2g only. there is any way to take full backup of database in part wise .

2-is any changing in tablespace size will effect the over all performance?
Tablespace ; Size (MB); Free (MB); % Free; % Used

I've read a lot about the different types of backup available with Oracle (hot and cold backup). However, I was thinking of a different way of performing this task. I'm currently using Windows Server 2008 R2 and Oracle 11g Standard Edition. I'd like to schedule an entire backup of my server via the utility "Windows Server Backup" (available for free).That way, I could recover my entire server with all the programs and files in case the latter crashes.I'm wondering if this solution could be used as a way of backing up (and recovering) the Oracle database. Should I still set up a regular hot backup with the Archivelog mode enabled in case some operations/transactions were being done at the time of the crash (for the data integrity)?
View 2 Replies View RelatedWe are using Oracle 10g R2 in Windows Server 2003. I'm trying to restore a database in a new server, using RMAN backups.
Our external consultant configured RMAN scripts for full and incremental backups but never tested them . Since he just doesn't show up, I'm forced to tested them, restoring the whole database in a new server.
My instance is named MTDPROD, and I will create all from scratch.
At current server, RMAN files are generated in:
//192.168.1.149/g$/XXXSRV4-ArcLogs/MTDPROD/RMAN
At new server, I run all these commands:
C:>oradim -new -sid MTDPROD -intpwd mtdprod
Instance created
-- I created the relevant folder hierarchy under <ORACLE_BASE>
directory
-- Then, I created the relevant directories for Oracle Database, as
follows:
--a. Create BDUMP, CDUMP, and UDUMP directories under '<ORACLE_ BASE>
[code]....
By instance, I see a lot of this kind of files:
- FULL_MTDPROD_20110529_386_1.BAK
- INCR_MTDPROD_20110621_480_7.BAK
And only see these two files:
- C-2169285856-20110527-03
- C-2169285856-20110527-04
It seems that this C-2169285856-.... files only were on 27/05/2011 and then no more. However, the FULL_... and INCR_.. files are generated every day. The FULL is generated at the end of each month and INCR is generated every day.

I am attempting to use an rman backup form our live server to restore live data over an existing dev database with a different name. I cant use the duplicate command as the versions of oracle are different (10.2.0.4 EE on live, 10.2.0.5 SE on dev) So I copied the backup sets including an autobackup control file onto the dev server. I set the ORACLE_SID to the DEV version (SUN43DEV) and startup nomount and restore controlfile from the backup location. This works and restored the live controlfile. However, I then wanted to mount the database and catalog the backupsets before making a note of the last archivelog etc and restoring the backup with set newname options. But when I try to mount the database I am told that the database has a different name (SUN43 is not SUN43DEV). I read somewhere that I need to set the ORACLE_SID to the live value (SUN43) and restore as that, then use nid TO RESET THE DBID and DATABASE NAME. However, my tnsnames on DEV has no entry for the live database, and we do not have any service defined through ORADIM for the live instance on the dev server. Should I be creating an entry in DEV tnsnames that actually looks at the LIVE server? or do I need to create a service and tns entry etc for SUN43 on my DEV server pointing at the DEV server I have not seen any mention in instructions of creating a service or adding the entry to tnsnames, or indeed adding an entry to the listener for the original live sid. I am worried that if I actually point to the live server then the restore would be attempted on the live server not dev even though I am running it from Dev.
Also, do I need to drop the existing database on DEV before I restore or will RMAN just restore over the top of it?
Finally, if I try to add an entry to the LISTENER.ORA for the new sid, when I stop and start the listener, or reload, the entry is not recognised. I also noticed that the existing SUN43DEV entry is not in there either, yet I can still use that SID - I am assuming that is because the listener is not being used and the sid is recognised from the existence of the service in windows services instead?
I want to load lakhs of records into a table. My problem is when after loading the ΒΌ of records my process is abend due to the size of my rollback segment area.
