Assuming you have a 9i database . where you have it enabled in archive mode , yet constantly deleting the archived redo logs , due to space constraints .
Will you be able to perform a full level 0 backup , and the following incremental backups , in the absence of the archived redo logs ? And are these incremental backups enough to recover the database or particular data files , to the point of the backup itself at least ?
URL....I'm practicing for the OCP test and one of the questions is that there is a backup from yesterday and the last archived logs are from the day before yesterday not mentioned if it's cold or hot backup.
If its a cold backup - cant we recover it? is it a must to have the archived redo logs also when recovering a cold backup? That sounds not logical since those logs are made only for a hot backup. URL.....

View 1 Replies View RelatedWe have a nightly rman backup that was complete and clean.The backup contains a Data File, Control File and a backup Archive Log file.The database server crashed with all the subsequent archive logs lost.
We are trying to recover from the three backup files.We are bumping into the backup piece missing as all the archive logs are done. how to restore with the exising backup files. the lost archive logs are probably salvageable.
Is there a way to automate deletion of applied archived logs after rollforward?
I'm thinking of crontab, and a script referring to the alert log to get the archived log filename.

here i have an question with oracle database backup strategy.my question is
how to backup my oracle database call DB11G without archived logs while the database is open for user activity and also this should be the base for an incremental backup strategy?
Is there any way to find out the last archived file's:
A) sequence no
B) Date and time
C) As well as the log group name.
I have 4 Log group.
I'm running Oracle 9i on AIX 5.2. I'm not using a recovery catalog, nor am I using media management software. I perform a full, online rman backup of the database and archived redo logs daily to disk, then use operating system commands to copy the backup to tape. There is only space on disk for two days' backups, so I need to have a retention policy of "redundancy = 1", and run a "delete obsolete" prior to the backup. The problem is that I don't want to subject the archived redo logs to this retention policy.
I have two physical standby databases connected by WAN to the primary site, and I might need archived redo logs that are a few days (or more) old in the event of a prolonged WAN outage. I've read about the "keep forever" option, but apparently it isn't available without using a recovery catalog. Is there any way to spare the archived redo logs from my retention policy?
Note: I want to "protect" the actual archived redo logs from the retention policy, not the backups of the archived redo logs.
I got a database on dataguard and my primary (db1) is shipping files to my standby (db2) with no problems.However, when I query:
select sequence#, status, applied from v$archived_log;
I see this:
SEQUENCE# S APP
---------- - ---
4 A YES
5 A YES
6 A YES
7 A YES
8 A YES
9 A YES
10 A YES
11 A YES
12 A YES
13 A YES
14 A YES
[code]....
So I did an alter system switch logfile on db1 then looked again and I can see new archived logs being applied.I thought all archived logs had to be applied on the standby since this is the very foundation of the standby database.Am I going to run in trouble later if I have a failover (unsynchronized database)
I ran the Full database backup as,
RUN {ALLOCATE CHANNEL CH0 TYPE 'sbt_tape';
BACKUP DATABASE FORCE PLUS ARCHIVELOG FORCE NOT BACKED UP DELETE INPUT;
RELEASE CHANNEL CH0;
}
Then I ran the restore, it failed with Quote:RMAN-06054: media recovery requesting unknown archived log....
When I backup archivelogs and choose to delete the input, it does not delete the multiplexed copy, but the specific file being backed up.So, ideally it should find it in Flah Area or at least in the backed up pieces which are there with it.Still why is it failing?
Also, in recovery, it is deleting the archived log after applying, RMAN does this if we use recover... delete archivelog command.I am using only RECOVER, still in output I can see RMAN deleting the log after it has applied it. WHY?
Is there any way I can get all the archive log files present in a backup piece. I tried following but it always gives me all the log files for each piece:
****
SQL> select s.set_stamp, s.set_count, s.PIECES, s.backup_type,
s.controlfile_included from v$backup_set s, v$backup_piece p where
s.set_stamp=p.set_stamp and s.set_count=p.set_count and
p.handle='5mjv4do0_1_1';
[code]....

I have an environment in which backup is performed of Oracle 10/11 databases with the use of RMAN and Tivoli Storage Manager (Data Protection for Oracle).There are several databases and for every one there is a daily full backup and hourly archive logs backup.
Sometimes when full db backup takes longer (up to 4 hours) archive logs backups are missed - as TSM node cannot perform two backups at a time. I would like not to have those missed backups.
Option A was to delete association of the arch log scheduler during full backup. But when removing association we lose historical data about backup. And we need historical data to be able to create weekly / monthly / quarterly statistics of completed backups. We need to have 99% completed.
Option B was to create two nodes in TSM (TDPO) and one will do full backup only and another one only arch logs backup. So the problem is moved to RMAN. But from RMAN specialist I heard that this may cause problems with full backup. During full backup also archive logs are backed up (at the start and end) so there might be a problem with accessing the file that is used by another process. And this may cause problem with full backup - which we want to avoid especially.
My oracle database is 11.2.0.2 RAC RDBMS on RHEL 5.6
We recently created physical standby database. How do we delete standby archive logs from physical standby?
I have Oracle 10gR2 database on a windows server, I have scheduled rman backup for this database from Solaris server
set echo onrun {
crosscheck archivelog all;
backup check logical database plus archivelog;

}
exit;
It is deleting the obsolete backup pieces but it is not deleting old archive logs (obsolete archive logs) and it is not even showing old archives as obsolete when I check thru report obsolete
I've got a legacy SAP system with oracle 8i on Tru64. No changes at all are made but for legal reasons we have to keep it up and running.
we currently do a full backup monthly by shutting down oracle and doing a backup of all the files to tape and that takes around 12 hours.
If I stop doing the full backup and I only backup the control file and the archived redo log files every month and I had to restore the full database years from now, would I be able to restore the database using the last full monthly backup and use the latest control file and archived redo log files?

Are there supposedly complete folder by dates each day? So I am missing archivelogs of 27th, 26th,25th, etc?
My supervisor wants to remove all the archivelogs since it was just a test for 1 year the DB is not actually YET been used. Problem is they want it to be used as soon as possible w/o recreating again the database and just removing some data on tables and removed archive logs. how to safely removed the existing archived logs and create a full backup with archived fresh to sequence 1.

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)
As per Client requirement, i need to configure archive log and backups in flashback.
