How To Change Default Destination Of Backup (archivelogs)
Jan 21, 2013
by default backup area is FRA, It can be change by db_recovery_file_dest FRA contains archivelog ,backupset,datafile,onlinelog folders..
NOW, i specially want to change backup dest. of archvelog to C: (suppose i have C , D, E, F , G) - (i know for archivelogs its log_archive_dest_N command can backup copies to other location but it also goes to default FRA )
backupset to D:
datafile to E:
onlinelog to F:
controlfile to G:
ALL SHOULD CONTAIN ONLY 1 DESTINATION NOT 2 FOR BACKUPS

I would like to rman command syntax only for the following scenarios.I have archivelogs the disk , sequence = 40, 41, 42 , 43and say, I backed up only sequence 41 file. next time I want to list (not backup) which archivelogfiles have not been backed up since the last backup (which was sequence 41 was backedup).I would like to be able to list 40, 42. 43 that needed to be backed up as a list in the RMAN. I understand that I can look at find from v$archived_log view and I can backup using (backup archivelog all not backed up 1 times to device type disk - i am ok with this).I need to be able to list the archivelogs that need backup from existing disk-directory of archivelog files from RMAN prompt.

Question: does oracle recover past the scn mentioned in the control file or do you need recover using backup control file for it? No specific scn,time specified.
Scenario: Restore database on new server + copy archivelogs from original to minimize data loss.
Backup : 5 AM
Archivelogs: 7 AM
New server:
Configure dummy instance
Restore spfile from tape
Restore controlfile from tape: SCN 5AM
Restore database (no scn specified) from tape: : SCN 5AM
Copy archivelogs from old server to archivelog new location: SCN 7AM.
Recover database
open database -> SCN 5AM or 7AM?
Does it recover till SCN 5AM (controlfile) or SCN 7AM (latest scn in copied archivelog)

We have faced database(10.2.0) issue cause incomplete recovery and have performed open resetlogs. This DB is of 12Tb. In 10g opening database with reset logs do not invalidate previous backups. we have another replica(no reset state)of this database which we sync using archives.how we can apply those archives(reset database)to previous database?

Can you take an incremental backup level 1 or level 0 without archivelogs?
syntax would bebackup as compressed backupset cummulative level 1 database.
The reason I ask is because when I run backup as compressed backupset cummulative level 1 database plus archivelogs # it runs fine, but when I run backup as compressed backupset cummulative level 1 database it just hangs.

I want to change the datafile permission as below. how to change the default value of the datafiles permission from (640) to (644) internally while creating the datafile from oracle side.

As per the bellow the default XML storage has been changed in 11gr2.
docs.oracle.com/cd/E11882_01/appdev.112/e10492/whatsnew.htm

Oracle Database 11g Release 2 (11.2.0.2) New Features in Oracle XML DB
The following Oracle XML DB features are new in Oracle Database 11g Release 2 (11.2.0.2).
Default Storage Model for XMLType
The default XMLType storage model is used if you do not specify a storage model when you create an XMLType table or column. Prior to Oracle Database 11g Release 2 (11.2.0.2), unstructured (CLOB) storage was used by default. The default storage model is now binary XML storage.
We have a application which works fine on r1 but not on r2 due to this change, we are going to investigate resolving the issue on the application in the future, in the mean time we need to be able to use the CLOB storage.
Does any one know where we can change this functionality back to the pre 11gR2 change?

I have a table called cust_file, his table consists of a lot of columns (one of these columns called cus_tax) and have a lot of data,I use oracle 11g, I want to change the default value of the column cus_tax to be equal 1, I wrote
ALTER TABLE cust_file MODIFY(cus_tax DEFAULT 1); table alteredbut
after I inserted new data to test the operation, I found that the new record has a value
= null for the column cus_taxthen
I tested using the following query select
data_default from all_tab_columns where table_name='CUST_FILE' and column_name='CUS_TAX'; no rows selected...
Change the default value of the column cus_tax.

I am using oracle 11.2.0 in linux platform.i have created a listener for the asm database. and i am using non default port of 1525 whenever i go for lsnrctl>status always shows for the port 1521. i don't want the default port 1521 and i have changed the local listener as listener1 with port 1525 protool tcp in spfile and registered with the asm database.Is there any option to change the default listener as listener1.
also,everytime when i give lsnrctl>show current_listener it is showing "listener"
i have set the current-listener to listener1 and save_config listener1 and reloaded.After exit and enter lsnrctl>status it will show for port 1521 When i attempt to start listener1 every time. it will prompt listener1 is already running.

I am studying about these two technologies and the only difference that I found was that optimization doesn't backup the duplicated archivedlogs.
If both ignore not changed blocks, what is more effective?
The optimization backup also has some tracking file?

A.2.2 Writing Backup Scripts for Disk and Tape Scenarios
As in the disk-only scenarios, the backup scripts in this section are categorized based on database workload. as stated very clearly it depends on the workload, more precisely the rate of block change. The size of the database can be found out based on formula from

so how would I know the rate of block change in order to know which script is suitable for me? I try to find out the rate of block change for the database based on change tracking file but based on

The size of the change tracking file is proportional to the size of the database and the number of enabled threads of redo. The size is not related to the frequency of updates to the database. So how do I determine the rate of change? can the rate of block change based on size of archive logs?

If I have a database size of 92G, based on the archive log size of about 3G per day, can I conclude that a change of 3G/92G is considered as few block change?

changing archive mode during DB running.Before in 9.2, 'ALTER SYSTEM ARCHIVE LOG START/STOP' is available for this job. But, after 10g/11g, it cause 'archive log stop has been deprecated'.
However, for my practice, I need to estimate archived logs size before backup them, so I need to stop archive log for a while and enable it later during DB running.
I check Oracle documents, it only mentions changing archive log mode at DB mounted but not open.

i did such commands
1. RMAN -> backup incremental level 0 database;
2. SQLPLUS -> alter database enable block change tracking using file '/home/oracle/block_change_tracking.tr';
3. RMAN -> backup incremental level 1 cumulative database;
4. RMAN -> backup incremental level 1 cumulative database;
5. RMAN -> backup incremental level 1 cumulative database;
and for such order i noticed that block change tracking file wasn't used for any cumulative backup. for each cumulative backup was done full scan over database.
it was used after i did incremental level 0 backup, and again incremental 1 cumulative.
if i want this feature to be usefull i should enable it before my incremental level 0, or i should do incremental level 0 immediately after i enable it?

I tried a Data Guard setup on Oracle Databases (version 10.2.0.4.0, on RHEL)
Primary Database is db5
Standby Database is db6
By the time I created standby database, 3 archivelogs (sequence 11,12,13) were generated on primary which I copied over to standby database server
Now while querying v$archive_gap on the primary database these archivelogs aren't listed
However at the same time querying v$archived_log on either Primary or Standby Database also does not list them
1)
In such case do I need to register these archivelogs on standby database?
Or else do I catalog these archivelogs on standby database?
Also as soon as standby database is started in recovery mode as a part of setup, 1 archivelog (sequence 14) was shown on standby
Now this archivelog has different path than the archivelogs generated later (sequence 15, 16)and v$archived_log shows it is generated as a part of FAL request (FAL=YES)
Question are
1) why it was FALed while redo apply services were active?
2) why this particular archivelog only which is part of FAL request is generated at different location
Does it generate at standby_archive_dest rather than FRA when FAL=YES?
3) why subsequent archivelogs are not part of FAL request or FAL request wasn't needed for subsequent archivelogs?
Primary database init parameters
*.db_name='db5'
*.db_unique_name='db5'
[Code]....
