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';
Would like to check how do we check the current value for limit channel in rman backup..
eg set limit channel d1 kbytes 2024800;
database size is 30GB is it recommended for RMAN backup

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.
Here is the details

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 writing a program for doing some file transfer between the client machine and the application server.I am using Webutil_File_Transfer.Client_To_AS to do the transfer and also using Webutil_File.File_Size to check on the file size at the source.
Once the transfer is complete, I also need to check on the destination file size (the application server running on Linux) for verification purposes and can't find the way to do it.

I am not sure what these input bytes are which is not matching with the database size(posted in the beginning of thread)? why it has to show as db full when i actually run a incremental?

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?

I 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)
