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.
online backup done thru RMAN.Suppose i am taking online backup of full database. During the backup, user's are inserting/deleting/modifying data. This data is getting stored as online archives. Once the database backup is finished, how these archives are applied to the database to make the database up to date.

I am try to import 4G dump in Oracle 11R2 version, in that we have around 9000+ Package Body which is taking huge time than other objects (about 8 to 12 hrs) and also it is expecting lots of system space (roughly about 10GB).
I have tried both parallel and non-parallel.how to improve speed of the package body import.

I'm taking export dump using expdp of some schema's of total size is 300GB. This is the par file:

here one biggest schema size is 250GB and the total size of all the schema's is 300GB. The file where am taking the dump has 350GB space but even then the expdp failed saying

View 4 Replies View RelatedWe are trying to restore a database on the different server using RAM incremental level 0 and 1 backups. We have weekly Incremental level 0 backups along with incremental backups on daily basis. During recovery of Incremental level 0 backup, RMAN is expecting/looking for Incremental Level 0 backup of prior week as well. Is this the usual process for RMAN to look for prior level 0 backup though we need to restore from the current level 0 backup and roll forward by a week with subsequent Level 1 backup.?
We intend to restore from the Level 0 of 1/16 and roll forward with daily incrementals till 1/22. RMAN is expecting level 0 backupsets from 1/9 backup as well and keep failing since those backups are not available. quick inputs since we are in middle of recovery and trying to resolve if this is even doable.

I have problem on using "delete obsolete" in RMAN.
First, let describe my backup configuration.
1. Full backup every Monday (17-Oct, 10-Oct, 3-Oct, 26-Sep)
2. Incremental backup for other days
3. Enable autobackup of control file
4. Backup archive log every day
5. RETENTION POLICY TO RECOVERY WINDOW OF 30 DAYS
6. Execute "Delete obsolete" every day
7. control file is used instead of catalog
The results observed:
1. Backup of control files older than 30 days will be deleted
2. Backup of archive log files older than 30 days will be deleted.
3. Backup of datafiles older than ~14 days but before 30 days are also DELETED.
In my example, the backup of datafiles created at 26-Sep is deleted at 16-Oct.
I tried "restore database validate until time "sysdate-22"" at 17-Oct. And RMAN reported "datafile xx will be created automatically during restore operation". It seems that RMAN failed to do restoration up to 22 days ago. The retention policy I set seems not effective on datafile backups.
I checked view v$backup_set and the "Keep" is "No" and "Keep until" is empty.
The only thing I can think of, is the settings of "CONTROL_FILE_RECORD_KEEP_TIME". It is marked "7" in the Oracle, which is less than the retention. But I suppose this only causes the backup not deleted, but NOT be deleted earlier.
I am getting below error while taking backup through RMAN.

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?
