How to recover standby by rman

Hello every one
Oracle 11g2 on window server 2008
For testing i have created standby server and shutdow it.
I have also schedule the increamental backup daily in the morning at 5:00 am.
Suppose if primary server has crashed at day time at 11:00 am as whole and standby database has lag of two days with respect to primary server
I have all archive log till 11:00 am, rman backup and control at 5:00 am.
Process that followed to recover the standby server .
1) restore the control file to standby database
2) copy the rman backup to standby server and catalog it.
3) restore the database successfully
4) recover database but it give error
RMAN-03002: failure of recover command at 10/31/2013 14:55:40
ORA-19693: backup piece C:\BACKUP\STD_5TONPQ57_1_1 already included
5) i have issued alter database open but gives following error

Hi Yasir!
If you have all archived log, and control file backups.
Then you must follow this steps
1. Restore Standby control file;
2. Copy archived logs to a folder (/tmp/arch) or FRA
3. RMAN>alter database mount;
RMAN> catalog start with '/tmp/arch'; (or FRA)
RMAN must be cataloged all archived logs;
4. Start redo apply process for apply archived log;
5. If All archived logs applied, then you can perform failover to standby database.
It means Standby database role will change to Primary.
Do you want this?

How to recover datafile.when control file auto backup is off

hi friend
i took hot backup of my database using following command
rman>backup database;
in my case controlfile auto backup is off.
and i have lost my all controlfiles as well as datafiles except spfile.
i have recovered control file using dbms_backup_restore package.
know i am able to mount database using following command
rman> startup mount;
when i wrote following command
rman> restore database;
i got following error
RMAN-06023: no backup or copy of datafile name found to restore
enven i have backup of datbase.
can anybody tell me how to recover datafiles in this case.
thanking you
sohail

hi,
I think you might have a problem here as the error from RMAN is described in the following metalink note
Doc ID: Note:100565.1
You should change you backup script to be something like
rman {
backup database include current controlfile;
do you have any earlier backups of your database?

Dear all,
How to create standby database by using duplicate,is there some doc to read?

Hi;
You can use

How to Recover database from old backup and full archive log file

Hi Oracle expert!
I met problem when restore my oracle database.
In my case:
- My database version: 10.2.0.2
- I have a database full backup (01-Nov)
- I have all Archived log file from (01-Nov -> 05-Nov)
- My database drop in 05-Nov with disk error (no datafile, no redo..).
- I have no any RMAN backup from (01-Nov -> 05-Nov)
How can i restore my database to 05-Nov?
Thanks

Hi Chinar.
When i used RMAN flow as your step, but i met the problem!
- After recover database i select sequence#, applied from v$archived_log;
--> it apply newest archived log that i had.
- but when I select Data from table created between 01-Nov to 05-Nov, it not found!
Not the same way the step:
SQL> RECOVER DATABASE USING BACKUP CONTROLFILE UNTIL CANCEL?
It apply newest the same archived log i had table created between 01-Nov to 05-Nov.
How can i do with RMAN to recover my table?That is not possible,if your all available archive logs applied using rman or through sqlplus(recover database using backup controlfile until cancel) and one of these logs contain your table then there are not any problems.So there are not any difference between recovery using rman and user managed(using sqlplus),but there main matter is applying all archive logs.So first check through rman list copy of archivelog all or list backup of archivelog all and identify there in rman repository is any information or not about these logs.

How can recover database using only Full Export ?

Hi,
I have one query , i have only Full export is given database , after full export sucessfully
database Crash by mistacally, how can recover it, i have only export is given no backup is taken (RMAN,COLD or HOT) statergy is use , How can recover it.

You need to recreate the database from scratch as imp requires a working database.
You could already do this by transforming the results from
'alter database backup controlfile to trace', a trace file containing a 'create controlfile' statement, into a 'create database' script.
After that step you apply your import. Everything after that import is lost forever.
One would ask for a sanity check of management and personell of a company, which has no backup strategy in place.

Table Truncated, Flashback is enabled ... How to recover.

Hi,
There is a table which was truncated, as we have flashback enabled. Even we have previously enabled row movement of the particular table.
How to recover ????
Thanks.

hi,
There are three options available:
1. Restore and recover the primary database to a point in time before the drop.
This is an extreme measure for one table as the entire database goes back in
time.
2. Restore and recover the tablespace to a point in time before the drop.
This is a better option, but again, it takes the entire tablespace back in time.
3. Restore and recover a subset of the database as a DUMMY database to export
the table data and import it into the primary database. This is the best option
as only the dropped table goes back in time to before the drop.
For the first, see information on performing incomplete recovery on a database.
The second and third options are virtually the same, it depends if the entire
tablespace data should be taken back in time, or just recovering the one table.
The tablespace point in time recovery (TSPITR) may be useful if there are
dependencies between the dropped/truncated table and other tables in the
database. For the second option, see RMAN documentation on TSPITR and/or Note 180436.1 RMAN Tablespace Point in Time Recovery Example. Both procedures
for the second and third options are very much the same. The differences are
that the TABLE PITR has to be exported/imported manually while the TABLESPACE
PITR is fully automated by RMAN.
This article will deal with the third option.
General overview of procedure to recover from a DROP or TRUNCATE table by using RMAN.
To recover from a dropped or truncated table, a dummy database (copy of primary)
will be restored and recovered to point in time so the table can be exported.
Once the table export is complete, the table can be imported into the primary
database. This dummy database can be a subset of the primary database. However,
the 'dummy' database must include the SYSTEM, UNDO (or ROLLBACK), and the
tablespace(s) where the dropped/truncated table resides.
The simpliest method to create this 'dummy' database is to use the RMAN
duplicate command. See:Note 228257.1 RMAN Duplicate Database in Oracle9iNote 73912.1 RMAN Creating a Duplicate Database -- Oracle8i
The difference between the two versions is that Oracle9i duplicate command
allows for a 'SKIP TABLESPACE' option. Thus Oracle9i allows for a duplication
of a subset of the database.
In Oracle8i, you cannot 'skip' tablespaces when using duplicate, so you must
duplicate the entire database. If this is not a desired option, or you must
restore the original database and thus cannot use
the rman DUPLICATE.
NOTE: The remainder of this information is for users who cannot use the
DUPLICATE command in Oracle8i. I.e., you want to restore only a subset
of the Oracle8i database.
Requirements :
a) RMAN backup of the primary database should be available to the
host where it has to be restored on.
b) Use of an RMAN-catalog database
c) Auxiliary instance created and started in NOMOUNT
(See Note 180436.1 step I. Create the auxiliary initSID.ora.)
Create this from the init.ora of the primary database and:
!!!!! IMPORTANT !!!!!!!!
If using the same host as the primary, be VERY careful as you do not want to
restore on top of existing files being used by the primary (production database).
Doing so can corrupt and crash the production database!!!!!!
- be sure all paths for this AUX instance are different than primary.
- be sure CONTROL_FILES parameter has different location but more importantly DIFFERENT NAME.
- add LOCK_NAME_SPACE to any value other than the primary database name.
- change/add SERVICE_NAME=AUX1.
- use the SAME DB_NAME as for the production database
- BE SURE you include the 'alter database rename file' command at the end
of the script. This changes the location and/or name of the online
redo log files.
d) Set ORACLE_HOME and ORACLE_SID set to the auxiliary instance
e.q set ORACLE_SID=AUX1
set ORACLE_HOME=<....>
!!!!! IMPORTANT !!!!!!!!
1: Restore and recover the tablespace
The restore and recovery is done by RMAN. Create a file
of the script below (e.q table_pitr.cmd) and execute the following
command :
$ rman cmdfile=table_pitr.cmd
NOTE: ORACLE_HOME and ORACLE_SID set to the auxiliary instance
NOTE: The Auxiliary instance IS the target to rman at this point.
The RMAN-script :
connect catalog rman/rman@v920_nlsu31
connect target /
run
allocate channel t1 type sbt_tape
parms='SBT_LIBRARY=/home/usupport/liblsm.so';
set until time "to_date( '09-10-2005 06:00', 'DD-MM-RRRR HH24:MI')";

set newname for datafile 2 to '/fs01/oradata/tspitr/undotbs01.dbf';
set newname for datafile 4 to '/fs01/oradata/tspitr/tools01.dbf';
restore tablespace system, undotbs1, tools;
switch datafile all;
sql "alter database datafile 1,2,4 online";

/* NOTE: Syntax within rman is two single quotes around each name, this may be operating system specific. */
release channel t1;
Explanation :
- Tape channel allocated, but could also be a disk channel, depending
on where the backups are.
- SET UNTIL TIME
User specified time, just before the DROP/TRUNACTE table
- MOUNT CLONE DATABASE.
This forces all datafiles to be put OFFLINE. Just for safety reasons.
- SET NEWNAME
New path for the datafile to be restored. Keep in mind that this is
done on the auxiliary instance and should NOT interfere/overwrite the
prodution database.
- ALTER DATABASE RENAME FILE
This is required to change the location of the online log files. When the
'resetlogs' is issued, Oracle will create online logs based on specification
in the controlfile. This command changes the location and/or name. If
this is being performed on the SAME server, not issuing a rename will
cause Oracle to reset the production online log files. This will corrupt
and crash the production database!!!!!!
- RESTORE TABLESPACE ...;
Restore the tablespaces which need to be recoverd.
This includes always the SYSTEM, rollback/undo tablespace and
the tablespace(s)where the dropped/truncated table resides.
The SYSTEM tablespace is always included as it containts most / all of
the objects owned by SYS and SYSTEM. Some other tablespaces might be
included as well when they contain objects owned by SYS and SYSTEM.
SQL> select distinct tablespace_name
from dba_segments where owner in ('SYS', 'SYSTEM');
- SWITCH DATAFILE ALL;
Make the changes in the pathname (set by SET NEWNAME) active in the
controlfile.
- ALTER DATABASE DATAFILE ... ONLINE
Online the datafiles which are restored and have to be recovered.
- RECOVER DATABASE SKIP FOREVER TABLESPACE ......;
You need to specify the complete list of tablespaces which will not be
recovered. Else the recovery fails, that it cannot dentify/file the
tablespace datafile. The SKIP FOREVER clause causes RMAN to take the
datafiles offline using the DROP option. Only use skip forever when the
specified tablespaces will be dropped after opening the database. I.e.,
all tablespaces except the one which contains your data.
The recovery of RMAN, checks the datafileheaders, to get a starting point
for the recovery.
2: Open auxiliary database with RESETLOGS
$ sqlplus /
SQL> alter database open resetlogs;
This step should ALWAYS be executed outside RMAN via SQL*Plus. If the open
is executed in RMAN it may effect the primary database's entry in the RMAN
catalog. Backups will fail with messages like:
RMAN-20011 "target database incarnation is not current in recovery catalog"
3: Export the table
The database is recovered and open, so it can be used by export.
Example:
$ exp userid=system/<password> file=table.dmp
tables=(<owner>.<tablename>, ...) rows=Y
4: Import the export-dump
Import the data of the dropped table back into the primary/production database.
Example:
$ imp userid=system/<password> file=table.dmp ignore=Y
5: Remove this AUX/DUMMY database
Shutdown and remove all files associated with this database. It has satisfied
your purpose. I.e., to give you an export of this table.

When one of contolfile is corrupt then how to recover the controlfile?

when one of contolfile is corrupt then how to recover the controlfile?

Let us say we have 3 control files and they are named as "cont01.ctl,cont02.ctl & cont02.ctl" and they are stored in three different mount points (/u01,/u02 & /u03)
first controlfile -> /u01/oradata/prod/cont01.ctl
second controlfile -> /u02/oradata/prod/cont02.ctl
third controlfile -> /u03/oradata/prod/cont03.ctl
1. According to the ALERT log file or any other source let us say the third controlfile got corrupted...
Now , what you can do is you have to shutdown the database and remove cont03.ctl and copy it form cont01.ctl or cont02.ctl :
$ cd /u03/oradata/prod
$ rm -rf cont03.ctl
$ cd /u01/oradata/prod
$ cp -r cont01.ctl /u03/oradata/prod/cont03.ctl
Now, you can go ahead and start the database. The database will start without any issue and it wil be ready for any operations on it..
2. Suppose all the files of the database got corrupted ... First of all you need to have backup of the database... the steps that are needed of this scenario are :
--> shutdown the database with abort option
--> Assuming its RMAN backup .. you have to first start the database in nomount state and you have to restore the contolfile from the last backup been taken and start the database in mount state and then perform the database recovery and open the database with resetlogs option(since you dont have current controlfile becoz you have restored it from a backup) :
Assuming its catalog:
$ rman target / catalog usr/pawd@tns
RMAN> STARTUP NOMOUNT;
RMAN> restore controfile (from autobackup) ; -- in case you have auto backup then use the autobackup option
RMAN> alter database mount ;
RMAN> recover database;
RMAN> alter database open resetlogs ;
After the database gets opened , immediately you have to take the backup..
Hope its clear...Cheers!

How do i implement the RMAN

Dear Oracle experts,
I am new for RMAN. I am good with Backup/recovery concepts. But I do not know about the RMAN concepts. Can you please provide the steps to implement the RMAN and how to recover the data file by using RMAN.
Can you please guide me?
I would really appreciate, if you could give me the steps to implement the RMAN. I am using oracle9i.
Thanks in advance.

There are articles on the Web - a google search will
reveal these. However, the best place to start is,
as always, the documentation. See:
http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96564/toc.htm
Hope this helps.

Mixing thread
yours recovery asking a lot of archivelog ,you are in the situation now like you are in no archive mode recovery..which requires last cold backup.
What you can do is restore yours old backup with its old controlfile and then recover till before that miissing log by using recover database using backup controlfile.

How can i do a RMAN backup of my database from the network ?

i'm using oracle 8i.1.7.3 with win server 2003
i want to know how can i do a RMAN backup of my database (sever machine A) from the network.
i'd like to save the backup in another machine (the same LAN, the same OS ).
to do that i've mapped a logical device in my comptur (z):
when i run rman command i got this error:
channel ORA_DISK_1: starting piece 1 at .......
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03009: failure of backup command ON ORA_DISK_1 channel at .......

OSD-04002: unable to open file
O/S-Error: (OS 123) The filename, directory name, or volume label syntax is inco
rrect.

Hi,
ORA-19504: failed TO CREATE file "\\remote\save\"make sure you have created this directory and change it's ownership (chown command)to oracle.
also make sure that oracle user has permission to write to this direcotry (chmod command)
hope this helps
cheers, walrus

How to recover Deleted file from HARD DISK

By mistake my entire AVCHD file of 90 Mts duration was deleted from my Hard Disk, this I realised after a week., in the meantime I have not added or deleted any file from this hard Disk. I had given my this hard disk to my service engineer to recover the video., he has tried and recover some 40 mb file., but I cant open this recovered video file in Premiere or any other video convertor programme., also I cant get any information about Video.
Can anybody in the forum help me and suggest how to recover my deleted Video from the Hard disk

Hi, hard disk data loss is actually a hard task for many users 'cause most of them think this kind of problems is a complicated situation. Here are some tips you need to know after data loss happened.
1. If you meet the file loss situation, keep calm and stop using your computer to do any read or write operation until you find the way to recover the lost files because any wrong operation.
2. If you've lost a file, time is of the essence. As new files saved to Mac hard drive or storage devices, the original files gets overwritten. So do not use the drive or disk which your deleted files are stored before at all, until you have completed the scanning and recovery process.
3. The system crashed or the files loss situation happens occasionally, so remember build a backup for the files periodically is strongly needed.
4. If you meet the file loss situation again, stop using the Mac or storage device right now, use another computer to process the files recovery.
5. Remember this, no matter at the normal time or after files recovery, build a backup for the files periodically is the best method to protect your files from data loss situation.
