Backup Flashback Data Archive And Restore On New Database?
Oct 14, 2012
Is there anyway to backup Flashback Data Archive (FBDA) data and can be restore on new database. I cannot find Oracle's document or any document explain about backing up this data.
I need store history for two tables in my system. I thought that Flashback Data Archive will be the best option. There is also another ways to do this but don't focus on this. I need to to this by FDA (Flashback Data Archive);
So my prerequisite was to create tablespace and flash back archive, and alter table to be archived.
alter table teta_admin.t_prac flashback archive audit_flash_archive;
and everything works fine but on sys user. i can query this table using "as of timestamp" clause
select prac_id, imie, imie_2, nazwisko, nr_ew from teta_admin.t_prac as of timestamp to_timestamp('2011-08-23 08:20:00','yyyy-mm-dd hh24:mi:ss')
but final construction of idea was to create additional user (interface), grant select on teta_admin.t_prac object and query archive data from interface user. and this is point of my failure. this don't work on new user.
interface user have such sys privs:
SQL> SELECT * FROM dba_sys_privs 2 WHERE grantee = 'INTERFACE'; GRANTEE PRIVILEGE ADM ------------------------------ ---------------------------------------- --- INTERFACE CREATE SESSION NO
and table privs:
SQL> SELECT * FROM dba_tab_privs 2 WHERE grantee = 'INTERFACE';

If flashback is enable in physical standby database 1. If we failover at 11AM can I flash back NEW primary database to 6 AM ? 2. if I convert physically standby database to snapshot standby database at 11AM , Can I flashback snapshot standby database to 6 AM and do some works on it (DML operations) then converting the snapshot standby database into physical standby database ?
I have read it in books that flashback uses undo data to create the flashback data or to flashback the database to a time in the past.Then, what is the role of archive files in flashback operation. Why it is mandatory to turn on archiving before turning on flashback. Also, if you remove the latest archive files, you can NOT flashback the data to a time in past (Oracle complains of missing archive files).
I have oracle 10g installed on my system and name of the database is "ORCL" for which I have schedule the incremental backup everyday. Mentioned below are the steps followed

Now I want to restore this backup to some other system with new database. How to do this recovery to some other database on new system.
I need to restore a backup of database A from into Database B. Both have the same names. Database B is already up and running.
I have a full rman backup of Database A ( it was taken with a recovery catalog which I don't have access to now as it was deleted ). I just have the full backup pieces including the control files. Is it possible to recover this database into Database B from this stand point.
I was thinking
2. Shutdown database B 3. Mount database B. It has same name as Database A. 4. With RMAN restore controlfile. Will a new controlfile be created from the backup directory I have the rman pieces for the full backup in ?
I've got a database I need to restore from a cold backup, but I don't have a copy of the multiplexed members of the redo groups - each group has 2 members, and we've only got a backup of the first.
I know this won't stop the database from starting, and I can recreate them, but for ease can you copy and rename a redo log file from a multiplexed copy to correct location like you can with a control file?
We have 11gR2 2 node RAC on Linux. ASM and OMF is used for database. The database on it is backed up using RMAN. We want to test the RMAN backup by restoring it to a new database on same server.
I trying to backup archive logs using rman in standby database. I'm able to backup archive logs using simple command it get's successfully completed. rman > BACKUP ARCHIVELOG ALL When i'm trying to do with keep command it's getting failed.I'm trying to do on physical standby databaseBACKUP ARCHIVELOG ALL KEEP UNTIL TIME 'SYSDATE+100' TAG = 'TEST'.
I have 2 server install oracle : server 1 and server 2
server 1 run database DB01
i use rman backup DB01 ( this command : BACKUP FULL DATABASE PLUS ARCHIVELOG DELETE INPUT; ) and move ( The database backup pieces , Controlfile backup piece, The parameter file i.e init.ora file) to server 2 .
At server 2 :
After start database with init.ora file and restore controlfile error :
RMAN-03002: failure of restore command at 07/22/2011 02:56:04 RMAN-06172: no AUTOBACKUP found or specified handle is not a valid copy or piece
Can we restore a database if we have only the datafiles available? The database has been dropped but we have just the datafiles with NO system, sysaux,users and undo datafiles that were saved after taking the database offline and then dropping the database. I know this is strange but if possible, I want to see if we can retrieve some of the data from those datafiles to another database. BTW, There is no backup available for this database except the dbf files on OS.
I have a task which is to get an export of an account.Easy, you will say, use Data Pump but I have not the database only a complete RMAN backup of it (including control file and spfile). Easy once again, restore the database and export but I have not the space to restore the complete database.
all segments of the account are in a couple of tablespaces I know the name (and I know I have space enough to restore them).
Unfortunately, I don't know the other tablespace names (but of course SYSTEM and SYSAUX), in particular I don't know the name of the undo tablespace and, of course, I have no connection with the source database and no way to know these tablespace names.
So here's the question, how can I restore part of the database (SYSTEM, SYSAUX, undo tablespace and a couple of other ones) from a complete backup without knowing the name of the undo tablespace and of the tablespaces I don't need?
We have a database server running oracle 12G on linux which is the production then we have a DR using the same version of DB and linux, I want to restore from tape into the DR from the production backup. the UNIX admin has restored already from tape the rman backup, i would like to know what are the steps to restore the backup from tape, also the DR database server was created identical like production using the same spfile etc.
were do i copy restored file into on the DR server? also then in RMAN do i just start the DR database and run the command restore database? what else do i need?
I have taken cold back-up of a complete database using below rcv from a server.
RMAN> connect target / run{ set command id to 'bkp_EMCPROD_db'; allocate channel c1 type 'sbt_tape' parms="BLKSIZE=1048576, ENV=(TDPO_OPTFILE=/opt/tivoli/tsm/client/oracle/bin/tdpo.opt)"; backup current controlfile format 'ct_t%t_T%T_d%d_s%s.ctl'; backup database format 'db_t%t_T%T_d%d_s%s_p%p.db'; backup current controlfile format 'ct_t%t_T%T_d%d_s%s.ctl'; release channel c1; }
I need to restore this back-up on another server of the same Database Name. Below is the rcv which my sr. dba asked me to look into for the restore.
/* From the new server to restore the back-up */ RMAN> connect target "rman/xxxxx@emcprod" connect auxiliary / run { set until time "to_date('Nov 03 2011 19:00:00','Mon DD YYYY HH24:MI:SS')"; allocate auxiliary channel c1 type 'sbt_tape' parms="ENV=(TDPO_OPTFILE=/opt/tivoli/tsm/client/oracle/bin64/tdpo.sacsun8.opt)"; restore database; }
I am new in oracle. I want to restore my database in oracle 10g enterprise. Actually i have a backup file(.bkp file) from oracle 10g xe and now i wanna restore in oracle 10g enterprise.
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)
I got missed the archivelog from primary DB.now its got deleted. But now it is stored in Tape_backup. i don't know about tape backup. how to access and restore the archive_log from tape backup. My tape setup is Legato..ultrium.
I am doing some test, seeking your expert opinion.I have a database and have the following backup strategy.
1) Database running in archive log mode. 2) First I backup all the table space excluding one tablespace 'DP_TS_LOB'.
RMAN> CONFIGURE EXCLUDE FOR TABLESPACE 'DP_TS_LOBS'; RMAN> BACKUP DATABASE;
3) I take a separate Backup of DP_TS_LOB tablespace.
RMAN> BACKUP TABLESPACE DP_TS_LOB;
4) I backup all the archived redo logs.
RMAN> SQL 'ALTER SYSTEM ARCHIVE LOG CURRENT'; RMAN> backup archivelog all delete input;
Now I wanted to restore the database from the backup excluding the DP_TS_LOB and bring it up and running. DP_TS_LOB is huge and used only on certain work flows. I don't want the database to be down until we restore DP_TS_LOB. I wanted to restore all the other tablespace and bring the database up operational and restore and recover the DP_TS_LOB tablespace datafile's in background taking the datafiles of DP_TS_LOB tablespace offline.I tried the following but unsuccessful.
RMAN> restore controlfile to 'g:ctl_bckctl_01' from autobackup; RMAN> restore spfile to 'g:ctl_bckspfile' from autobackup; RMAN> sql "create PFILE = ''G:ctl_bckPFILE'' from SPFILE = ''G:ctl_bckSPFILE''";
Update the new parameter with new control file name. Copied the control file and parameter file to corresponding location.
First I assumed "Recover Database" will only recover online database files. But got the following error.
RMAN> recover database;
Starting recover at 27-JUL-11 using channel ORA_DISK_1 RMAN-00571: =========================================================== RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS =============== RMAN-00571: =========================================================== RMAN-03002: failure of recover command at 07/27/2011 18:23:03 RMAN-06094: datafile 8 must be restored
Then I tried recovering data file separately, but same error.
RMAN> recover datafile 1;
