View 1 Replies View RelatedI have 2 seperate rman backup one backup is of only datafile ,spfile and controlfile which i am able to restore and recover without any problem say bkp1 taken at 10 am
other set of backup is of only archive log files of same day but later time than datafile backup say bkp2 taken at 8pm...if i restore and recover bkp1 and try to restore bkp2 it gives error datafile exist (possibly due to fact both backup have control file)
if i just restore bkp1 and try to restore bkp2 so that i can do one recover at time
it gives error datafile permission issue (possibly due to fact both backup have control file)
I want to restore database upto 8pm time how can i use both bkp1 and bkp2 to do it(restore datafiles and apply all archive logs on it)

I have a table named employee with 10 records. Empid is the primary key and empsal contains salary of the employees. I created backup of this table and name of backup table is empbackup.
Now empsal was updated to empsal*10 in employee table and 10 more records were also inserted in employee table. Now I want to restore the empsal column for 10 employees from empbackup(as initially there were only 10 employees in employee table when empbackup was created) table how can I do that in PL/SQL or Oracle?

View 4 Replies View RelatedYesterday my colleague noticed that, the complete data (1 year) got missed out from a table and the data is available only from last friday.
And then we restroed the data from the backup.
Now we have been asked to find out who has deleted or truncated the data? But in the database, audit is enabled only to log sys operations.
So is there any way to find who ran the delete or truncate command on this DCA_CLA_BATCH table on friday?

View 12 Replies View Relatedwe are using oracle 11.2.0.3 on linux platform and was wanting to know if there is a way to backup just a single table partition using rman? If so does the database need to be running in archivelog mode in order to do this with the database online?
This is a database that has one single huge table that is partitioned by day and we are attempting to export out daily partitions using datapump export so that we can archive them to tape but the disk system we have is not able to keep up and the export of roughly 128gb is taking over 8 hours and is failing because the undo is aging out. We would like to bypass writing the partitions out to disk and just stream them to tape if at all possible?
Our client has this scenario:May 23th 4:00 PM a user truncate a critical table. The customer need to recover the data before truncate.
The recover materials list like this:
1. A cold backup of this database at May 1th.
2. The archive log except May 1th ~ May 15th.
3. Every day exp at 00:30 and 12:00.
Is there any way to recover the data before truncate table with these material?
I am trying to calculate the compressed size of backup of my database by excluding table space ( and all the tables in that table space).
I know how to calculate the size of particular user DB size.
select sum(bytes/1024/1024)"size" from dba_segments where owner='ABC';
Is this possible to take the dump of a huge table , say 500gb, into multiple files and then import it in other database? if yes how can we do it?
Note that it is a single table with 500GB of size.

We are doing RMAN Duplicate set until time to refresh daily our test database for our developers and it taking long time to finish. We noticed on the restore log that RMAN was using a day old old backup pieces to refresh the test database and don't immediately use the latest backup pieces instead.
For additional details here's the rman duplicate command we are using which we run daily(mon-sat) at 4am once daily full backup on production completed.
RMAN Duplicate commands:
run
{
set until time "to_date(to_char(sysdate,'Mon DD YYYY') || ' 04:00:00', 'Mon DD YYYY HH24:MI:SS')";
allocate auxiliary channel ch1 type disk;
duplicate target database to testdb;
}
exit
Is there a way on how to let RMAN use the latest backup pieces instead?

I am trying to clone a database on another server with different direcory structure. So that path on the source db server are /u04 whereas on on target db server it would be /u03.
Since this I am testing it on small database initially I have kept all datafiles, backup and archivelogs at /u04 and /u03 on the source and target db servers respectively Now I have copied the backups from source db server to target and since path is changed, I cataloged it
However during restore I am getting

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)?
