We run a 10.2.0.4 database and the rest 11.2.0.3. All databases are on RHEL 5.7.
Our backups are via RMAN, with the data files, controlfiles and spfile saved to disk, then each day, it is copied off site to a backup server.
My question is around logs archiving and RMAN. Our current situation is: -We do not save the logs to archive via RMAN. for example: backup of the list of the archivelog all; gives "specification does not match backups in the repository. -We set the archive_lag_target so archiving logs is produced every 30 minutes. -a cron job running on a remote server runs periodically to synchronize data (rsync server) the directory of archives with a remote control. -daily archive logs on the server host are bzip. Purge of these newspapers is scheduled for more than 3 days rman 'window of recovery '.
I'm interested in feedback as to if our strategy around archiving logs is correct or not.
Should we be backup logs archiving via RMAN? Are there potential problems with our approach? We just kept our backups in this way the DBA in the past want to see newspapers archived as opposed to it while a backupset.
Curious to know what others are doing.
Hello
Welcome to OTN!
Archivelogs with RMAN backup is a better option. When the archives are supported by RMAN, RMAN would be aware of the backup items which are required at the time of the recovery archives. You don't have to do it manually.
On the disk space, you can delete the archives once they were saved by RMAN.
RMAN > delete any backup archivelog entry;
This supports the archivelogs and then remove the archives from the disk.
If you have a dataguard configured, you can set the deletion policy 'applied on Eve', which removes the archives as and when they are applied to the database ensures there by the management of disk space again.
RMAN > configure archivelog political of deletion to applied pending;

I want to perform cold backup with RMAN for the same thing I want to know the following:
1. What is the script / command?
2. how to completely restore a cold backup (ex:-if I lost all my data, redo and archive)
3. is it compulsory to open the database in mode RESETLOG after recovery (since I was a backup to cold)?
Thanks in advance
A backup 'Cold' is called a 'Cohérent' backup See http://download.oracle.com/docs/cd/B19306_01/backup.102/b14192/bkup003.htm#sthref297
Backup: From the RMAN command line:
SHUTDOWN IMMEDIATE
STARTUP MOUNT
BACKUP DATABASE
BACKUP CURRENT CONTROLFILE -- to get the controlfile in a separate backupset
Restoration:
STARTUP MOUNT
RESTORE DATABASE
ALTER DATABASE OPEN
If you use a SPFILE, you can have a backup SPFILE included automatically with the backupset controlfile with CONFIGURE CONTROLFILE AUTOBACKUP on and CONFIGURE CONTROLFILE AUTOBACKUP FORMAT...
Hello How to restore the tablespaces only 4 not all areas of storage in one database to the new database of cloned all cloning with RMAN?
I don't think it's possible to restore only 4 storage space for the database 'auxiliary '. Instead, you can use the "SKIP TABLESPACE" cloning while clause.
You can exclude the tablespaces that you don't want the database duplicate with the SKIP TABLESPACE clause. You can exclude any tablespace except the SYSTEM tablespace or tablespaces containing rollback or undo segments.
Refer to this http://docs.oracle.com/cd/B14117_01/server.101/b10770/rcmsynta28.htm
I intend to clone my PROD database to create a database of emergency with RMAN, the situation in the present case, it is that I want to use the same db_name so create spfile scp to the target server, run a level 0 backup dB, create the same file structure as well, but I'm confused because when I connect to RMAN to perform cloning as you can see...
RMAN> run {
allocate auxiliary channel c1 device type disk;
allocate channel c2 device type disk;
duplicate target database to 'prod1';
}
-Is it possible that crushes my source PROD1 database
-C' is ok, if I run the clone with the database of the source open with few users working? Even he will operate a backup, this will obviously have a performance impact but also the integrity of the data? I'm not sure what other files of this procedure will be used in clonning.
-Should I enter into channel c2 backup full path to the source server?
We have active 3.5 to database on solaris. We need to clone this DB to another machine. We can not stop the primary DB. Thus, the cold backup is out of the question.
We believe from a full backup of RMAN overnight. 05:00 early morning it will be done. I reach Office only at 09:30. So, I need all the changes (logs archived) generated after 05:00 to apply on the DB newly created.
How you guys do this with RMAN, because backup control file in the full backup does not know about the Archives of logs generated after 05:00?
Take the simple path: take a backup costs the controlfile (and all new ArchiveLogs) at 05:00 and copy the backup to the new server. Use this new backup controlfile.

Hello gurus, I have a problem with RMAN, I'm trying to 'Cloning' an Oracle Instance with RMAN database and I have several errors, but I checkk all Forums and documentation I have 2 servers in 10.2.1 in Solaris and other in 10.2.4 on Linux And I'm running in my 1Mode of the server as follows: RMAN target connection. connection Assistant sys/manager@TESTDB10_SITE2.world run { allocate auxiliary channels ch1 type disk; the value of newname for datafile 1 to ' / u02/oradata/EVTM/system/system01.dbf'; the value of newname for datafile 2 to ' / u02/oradata/EVTM/system/undotbs01.dbf'; the value of newname for datafile 3 to ' / u02/oradata/EVTM/system/sysaux01.dbf'; the value of newname for datafile 4 to ' / u01/oradata/EVTM/data/users01.dbf'; the value of newname for datafile 5 to ' / u01/oradata/EVTM/data/tbs_tpaper_data_01.dbf'; the value of newname for datafile 6 to ' / u03/oradata/EVTM/index/tbs_tpaper_idx.dbf'; the value of newname for datafile 8 to ' / u01/oradata/EVTM/data/users02.dbf'; the value of newname for datafile 7 to ' / u01/oradata/EVTM/data/perfstat_01.dbf'; the value of newname for datafile 9 to ' / u01/oradata/EVTM/data/tbs_evtm_quest01.dbf'; the value of newname for tempfile 1 to ' / u02/oradata/EVTM/system/temp01.dbf'; duplicate target database to EVTM PFILE = ' / u01/app/oracle/product/10.2/dbs/initEVTM.ora' nofilenamecheck LOGFILE Group 1 ('/ u01/oradata/EVTM/rdo/redo1m1.log',) ' / u01/oradata/EVTM/rdo/redo1m2.log', U01/oradata/EVTM/RDO/redo1m3.log') SIZE the 51200 K,.

Is it possible to duplicate/clone of Soalris in Linux? :-)))))
You can not use the command DUPLICATE between platforms (see duplicate restrictions in the documentation). It is possible to perform a cross-platform via RMAN transport. This process is also explained in the documentation.

You have an additional complication, patch levels are different. Perhaps datapump here is a better solution - depending on the size of the database.
And I hope that Solaris on x 86-64 (no SPARC), otherwise the next complication.
I'm having a devil of a time to set up my v2 WET11 to allow my XBOX be fully connected. I can configure and connect the bridge, ping, ftp files to XBOX etc. Only problem is when I try to play bound. I can see the game in progress on the second XBOX but cannot participate. Related game works perfectly when Xbox is wired to the router. I know that play bound depends on each game console broadcasting their MAC, so I need to clone the MAC address of the XBOX to use the bridge.
Unfortunately the WET11 web configuration interface I cannot do. Under Settings/Advanced cloning Mode, all controls are disabled - greyed. This includes the control that allows you to turn on cloning. I took a shot the script behind the page and it seems that it checks to see if 'disable cloning' is selected and if so, disables all controls of cloning, including one that would allow me to get back on. Since the default value is disabled, it is the programmatic equivalent to lock the keys in the car. You can take a look at here emulated interface:
Of course, the demo is fully functional and do not exhibit the problem...
Many people have described solve their XBOX related play questions by cloning the MAC address of the XBOX and see change settings using the web interface.
I tried different versions of the firmware 2.06 and 2.07, 2.08 USA 2.08 EU. Same results. Tried the Installer Wizard 1.06 worm, but he does not even include the MAC settings.
Had two cats different with online support agents and the two seem as puzzled as I am.
Am I missing something obvious? Depends on the availability of cloning parameters options elsewhere in the config utility? Is the interface designed for cloning taking place without intervention of the user on the v2 and v1? (doubt)
Has anyone else seen elsewhere?
I know that people have written code to pull the strings of parameters off the unit then maybe the reverse is true and I can write the script to directly change the settings.
Any suggestion would be appreciated.
Rick
Well well well - apparently the firmware is not totally compatible with IE7. Downloaded Firefox and the interface works as advertised.
All output data base Oracle can restore backup sets and copies created by any prior release of Oracle Database.
However, in order to open a database, the data must match the version of the Oracle binaries. If you restore and recover a previous version of the database, you will need to update database permission to open it.
RMAN cannot upgrade and migrate a database, but you can use the wizard for DBUA do. I suggest that you only consider this document showing your upgrade options:
Unfortunately, there is no way to upgrade direct 11.1.0.6 12.1 and you must upgrade the database to 11.1.0.7 first before restoring it. Other options, see the link above.
We backup data base of sbt with rman and nmda library (networker).
We want to copy the disk sbt backupset. Is this possible?
Kind regards
William
I remember that this is not possible. It was perhaps possible to redraw the rman backup and restore concepts, but there is probably no real business applications. Remember that a band or an sbt (series tape backup) is a streaming device. You can read from tape or write about a band, but you can't read and write in the same band at the same time. What syntax would you choose to perform an rman backup from tape to disk or tape to tape? Rman backup you can specify a peripheral channel of exit and entry for the use of the restore command. As far as I know, the rman backup source is the database control file and it reads no Ribbon.
