Backup of archive logs
I have a cron job that backs up complete zero on Sunday. I have an another cron job beginning level 1 backups, Monday to Saturday. I have a 3rd cron that runs every 2 hours for each day of the week in order to safeguard the archive logs.I have concerns with the 3rd cron job. Lets say the data in the database has not changed in the last 2 hours. This cron job would always run this script, create another backup rman (taking more space on the server). Is my understanding correct that rman is not smart enough to know what data has changed during backup of the Archives of newspapers so that the two components of backup are not store duplicate information? The reason why I think it's because the size of the pieces cackup for this archive log backups stop a lot of the time very similar (but not the same) in size.
Lets say the data in the database has not changed in the last 2 hours
That you have taken backup the archivelog at 07:00 and the next execution of the annex is at 09:00. Say that there are about 100 archives that have been backed up at 07:00. And from 07:00 until 09:00, there was that no transactions took place, in other words, that the data in the database has not changed in the last 2 hours.
In this case, RMAN wouldn't be backup archives that have been backed up at 07:00. If there is no generated archives between 07:00 and 09:00, RMAN wouldn't save anything.
If the archived log was not saved, it will be.
If the archive log was not saved and is missing, you will get an error.
If the archived log was backed up, RMAN will not back up again.

Recovery of database of old backup and archive log file complete
Hi expert Oracle!
I encountered the problem where my oracle database restore.
In my case:
-My version of the database: 10.2.0.2
-J' have a full database backup (01 - Nov)
-J' have all the archived since (01 - Nov-> 05 - Nov) log file
-My database down to 05 - Nov with disk error (no data file, not again...).
-I have no backup RMAN (01 - Nov-> 05 - Nov)
How to restore my database to 05 - Nov?
Thank youAfter you RESTORE the DATABASE,
Use the VALUE UNTIL to set the Point of recovery to 05 - Nov, and then RECOVER the DATABASE
OR
Use the SQL command "RECOVER database with the HELP of BACKUP CONTROLFILE until CANCEL" that will keep asking 'future' ArchiveLogs backup.Hemant K Collette

database backup and archiving log
Hi all
I have two scripts:
Full_db_backup.sh
ARCHIVELOG.sh
Full_db_backup.sh I have the below
in Archivelog.shbackup incremental level 0 device type disk tag testTAG database plus archivelog;
My question;BACKUP ARCHIVELOG ALL tag testTAGArch not backed up 2 times;
can I have the below for the backup of the database?
and if so the 'saved 2 times; not' it's only for the archivelog? or not 2 times for archivelog backups of database backed up?backup incremental level 0 device type disk tag testTAG database plus archivelog not backed up 2 times;
Kind regardsNB wrote:
Thank youI will still have the below question about backup of control file that you mentioned in the below:
Other point: As you are making copy of your backupset using a padronized tag, I suggest you include current controlfile on your backup, because Autobackup have a default tag and we cannot change it. So I suggest you do this: backup incremental level 0 database INCLUDE CURRENT CONTROLFILE tag 'my_backup' plus archivelog;
I can't do: Configure auto backup device type disc format control in two different places?
one on my site of the archive and the other at FRA?
Currently, I have below:Configure the control auto backup disc format of type device to "%f".
You can create a custom script to run at the end of your backup:
This query above will create a command to get 2nd copy of your automatic backup;The below script check the backup strengthened to FRA on autobackup dir on the last 5 minutes... you can change it as you wish.
SELECT 'backup backupset from tag '||TAG||' format ''/u01/app/oracle/'||TAG||'%U'';' FROM V$BACKUP_PIECE WHERE START_TIME > sysdate - 5 /(24*60) and HANDLE like '+FRA%autobackup%'
Suggestion:
Disable the automatic backup before making a 2nd automatic backup copy;
Run the command to make automatic backup
Enable autobackup after 2 do an automatic backup copy; -
Recovery window retention policy removes the archive logs before backup?
Hi all
Oracle 11G on Windows 2008 R2
This afternoon, I've changed my retention policy RMAN "RETENTION POLICY 3 REDUNDANCY"on RECOVERY WINDOW OF 3 DAYS RETENTION POLICY
However, I checked tonight and after that my daily backup, all the archive before backup logs had been removed! So that means I don't think I can restore to any point in time, before my daily backup. All newspapers .arc were there after the backup. Then I tried another test and began the daily backup again. During the backup process, archive logs were deleted again! Now, I don't have any archives of newspapers...
Is this good behavior OF RETENTION POLICY RECOVERY WINDOW? I thought that she would keep all the files needed for to restore me to any point in time for the previous 3 days. When I used a REDUNDANCY, with my daily backups, he kept 3 days of backups + archiving logs so that I could restore point-in-time at any point. How can I use WINDOW RECOVERY so that I can actually restore to any point in time for the 3 days?
I wanted to change WINDOW of recovery, since I read that using the REDUNDANCY, it keeps only X copy a backup (so if I ran the backup 3 times a day, I would have only these 3).
Thanks in advance.
After a database RESTORE, Oracle tries to RECOVER a DATABASE. He tries to 'find' the archivelogs for this phase in the location expected archivelog. If they are NOT present in the location expected archivelog, it attempts to restore backups before applying them.
Since your BACKUP... DELETE ENTRY deletes the archivelogs after that that they are saved, Oracle will have to use backups to recover the archivelogs.

Hi guys,.
Can advise you on the syntax for the rman backup of archive logs generated in the last 2 days?
Wouldn't be 1 or 2?
Thank you!
1 BACKUP ARCHIVELOG UNTIL ' SYSDATE-2';
2 BACKUP ARCHIVELOG FROM TIME ' SYSDATE-2';Run the commands and see what is RMAN - it will show you what files it runs a backup of!

Archive log deletion with no backup of the archive logs
I suffer from enormous size archive of the newspaper. In my previous post, I asked for help. I almost 480 GB archive log every day in our database of 11 2 under redhat linux 5.8 GR. Now, if you please help me in another case.
If I take backup of archive logs and run delete archivelog everything until ' sysdate-1' with each backup database of day how it affects. " In my opinion there should be no problem in that I have the last incremental backup and recovery 1 days archive log in archivelog destination. If I do not archive log backups to how it will be different. Help, please.>
Hello
Sir, I know how to remove. But in my opinion delete up to sysdate-1 and taking no backup of the Archives of newspapers will
no effect. Is in my opinion is right or wrong, that is the question.What I read in your original post, is that you take a daily incremental backup - Yes? I'm assuming that you also take
a full backup on a regular basis (Sunday?).I was working on the assumption that the foregoing is available? I worked on a project where installation has been similar. We
tested regularly backups - I hope that you do the same thing?What we used to do was FTP (script Unix - cron job - if you Google you will find Python or Perl to do the same thing - that is)
what I wanted to, but was cancelled - very 1980, anyway) the archived redo logs on to a specific computer that holds only these files.
After FTP "d - they have been removed from the server, freeing up space.Now, you say you have TB 0.5 per day - while more than a week, you will need a machine with ~ 3 TB of disk - if you can get a kind
the scenario as this place and running, then you will have both your incremental backup and your archived redo logs for the last
24 hours and the full backup with recovery archived records dating back to this full backup. You can also always archive on tape if
suits. So, you will have redundant coverage - 'belt and braces' as the Americans say.But, to answer your question directly, "take no backup of archive logs have no effect" - that is true - it
will not affect the operation of the database server, but if I were you, I would hang on to enough archived redo log to return to the
last backup. That's just my humble OPINION.HTH,
Paul...

Deletion of backups of level 1 and archive logs
Hello
Everyone knows that "the retention policy would be applicable on level 0 backups or only full backups.
So how will be reported what backups and level 1 backup of archive logs are no longer needed for recovery?
And after that as the command "remove obsolete", y at - it a command to remove these unwanted 1 level and archiving logs backups?
Any suggestion?
Thank you
Nitesh.So how will be reported what backups and level 1 backup of archive logs are no longer needed for recovery?
If you have the revoery retention strategy window 1 day and you take backup of level 0 Sat and then consecutive level until Friday 1 daily backup, again on backup sat level 0 will be obsolete previous level 0 backup sat and its seven consecutive level 1 so is found in the archived log alls before this level 0 current backup will be marked.
Obsolete report will show you alls backup piece and the archivelogs that are marked as obsolete.
And after that as the command "remove obsolete", y at - it a command to remove these unwanted 1 level and archiving logs backups?
What do you mean by backups, undesirable level 1, on what basis you say that backup of level 1 are undesirable?

DataGuard archiving logs go?
Hi all
9i
OEL5
I'm following the dataguard configuration document.
One of the tasks is to run:
RMAN > backup filesperset remove all 10 ArchiveLog entry;
He created an output file > piece handle = / p01/oradata/PROD/dbs/06dlfmmt_1_1
Can it remove the archive logs.
My problem is, I want to still manually restore another set of database for replication so I still need that archive logs to be applied to this database 2 (non-dataguard).
Can I use this backup of archive logs merged to manually apply on my second instance?
Thank you very much
JC
Yes, controlfile of today can be used for backup of database of yesterday. However, if you have added new data files or tablespaces from backup, they would be reflected in the controlfile but not in the backup.

Retention policy for archive logs.
Retention policy is set to "REDUNDANCY 2".
We do the complete disk backup without archive logs at 12:00.
After that, we make full backup with newspapers to archive tape at 18:00.
RMAN will consider newspapers to check-in after 12:00 as obsolete as it is backed up to tape?
Thank you.
REDUNDANCY applies only to the data files and control files. For archiving logs, there are POLICY of DELETE ARCHIVELOG. But "remove obsolete" won't use POLICY of DELETE ARCHIVELOG, so archiving logs should be removed separately if they meet this policy.

Published by: 995796 on March 24, 2013 02:27You must exclude this backup archivelog. Rename the archivelog (via asmcmd) and then run OVERLAP ARCHIVELOG ALL while Oracle would mark it as 'Out of date' when it does not find the archivelog. (You can also run an ARCHIVELOG DELETE or REMOVE the ARCHIVELOG EXPIRES to logically remove).
You should document this archivelog missing so that any required later retrieval knows this archivelog isn't available, so a point in time to recover to any point of the last backup before this archivelog to a point in time of the archivelog or as the result of it would not be possible until the next backup.
Needless to say, take a fresh database backup.

Problem with the archive log when you use RMAN for backup and restore (11g 2)
Hello world
Please help me solve this problem.
I'm just beginner in Oracle Database (11 g 2). Today, I had a problem, I tried to back up and restore my db by RMAN. I delete all the files in /u01/app/oracle/oradata/orcl / * , then I restore them easily, but the point is I have a table, I can restore Hungarian, but cannot restore anything ranks in it (something wrong with step restore database). I'll tell the detail below.
-First, I create a 'Day' with command table create table hr.day (varchar (20)) day. Then I backup complete by this:run{
allocate channel bkp device type DISK FORMAT '/u01/backup/DB_FULL_%d_%T_s%s_p%p' ;
backup as compressed backupset incremental level 0 tag 'DB_FULL' database include current controlfile;
backup as compressed backupset tag 'ARCL_BKP_FULL' archivelog all delete input;
crosscheck archivelog all;
crosscheck backup;
delete noprompt obsolete;
release channel bkp;
}
D ' other hand, I have insert 'Monday' to table. then do an incremental backup by this:run{
allocate channel bkp device type DISK FORMAT '/u01/backup/DB_INC_%d_%T_s%s_p%p' ;
backup as compressed backupset incremental level 1 tag 'DB_INC' database include current controlfile;
backup as compressed backupset tag 'ARCL_BKP_INC' archivelog all delete input;
crosscheck archivelog all;
crosscheck backup;
delete noprompt obsolete;
release channel bkp;
}Repeat 7 times (Monday-> Saturday). And I got these files:

If i ignore it and open the database, just my table in full backup come back but rows was not restored. I'm sure the problem is my archive log backup but i don't know how to solve it. Plz help me.Sorry for a long post.
> 1 and from the 1205841 SNA sequence
The SCN that indicates Oracle is above the range of SNA that you have in the ArchiveLog backups for sequence 1 to 15 (15 sequence ends at 1205840).
The message
channel ORA_DISK_1: restoring archives Journal
Archives journal thread = 1 sequence = 15
channel ORA_DISK_1: backup/u01/backup/DB_INC_ORCL_20160120_s117_p1 piece reading
channel ORA_DISK_1: piece handle = / u01/backup/DB_INC_ORCL_20160120_s117_p1 tag = ARCL_BKP_INC
indicates that he has restored the sequence up to 15
You can check the log file alert database instance for messages on the fact of recovery.
He is now asking sequence #1 it seems you did a RESETLOGS after sequence #15.
Note: If you have NOT issued a COMMIT after the line is INSERTED in the table 'Day', the recovery of the database will have no * transactions * to retrieve. An uncomitted transaction is cancelled.

Pull on the RMAN backup archive logs?
Environment:
Oracle 11.2.0.3 EE on Solaris
Physical standby
I have a gap of journal archive at the moment. The missing archive logs have been saved on the primary and have not yet been transferred to waiting due to some maintenance work performed on the standby server.
The database will be able to recognize that the missing archivelog files are in the RMAN backup files, restore them and send them to the update server standby for application?
If not, will it restore manually, copy them to the standby server and save them for their application?
Thanks a lot for your help!
-gary
Were the archivelogs deleted on the primary once they have been saved? If they have been deleted on the primary, then you can:
1 manually transfer the backup to forward files
2 replace the archivelog destination configured on the eve
3 restart the managed recovery on the standby process, and the computer should be able to detect and apply the missing archivelogs.
If they have not been deleted on the primary and are always available in the archivelog directory configured, then the process of Data Guard should be able to detect and automatically fix the gap.
If you have a long interval archivelogs missing and you use + ASM, you can also try to use an incremental backup to roll forward the database pending, this article provides a good step by step: the steps for Rolling forward a standby database using RMAN incremental backup. (Doc ID 836986.1)
Kind regards

The Archive Log backup retention policy
How can I define retention policy for backups of the log of the Archives?
The question and the answer that you have marked as "Right answer" is misleading.
For removal of journal policy archived, see below.
Configuration of RMAN environment
For the real question displayed "How can I define retention policy for backups of the log of the archives?", see link below. ""

RMAN backup for lack of archive log - Urgent
Dear all,
How to take backup in oracle rman for lack of logseq at logseq archiving log.
Please help me urgent.
Thank you
ManasThe SNA method before roll is easiest to get your sleep in harmony rather than completely rebuild.
The RCS on primary continues to rise and if the archives get generated on primary at a regular stage, would be late the night before by a huge margin.
If there is a gap of newspaper caused lack of archives and his backup is not available, then I'd rather go with the Roll Forward YVERT method.
