Database ALTER DATABASE RECOVER using backup controlfile with AUTO option
Hello. I was recovering a database today and had a little blip.
I have published the following:
Database ALTER DATABASE RECOVER using backup controlfile
I then chose the AUTO option, allowing Oracle to select all available log files so that it would recover to the last log found in the destination of archive
However... has performed the following:
ORA-00289: suggestion:
/U03/Oracle/stk2proddata/archived_logs/arch1_242449_737547185.dbf
ORA-00280: change 30031145558 thread 1 is in sequence #242449

ORA-00308: cannot open archived log

ORA-27037: unable to get file status
Linux-x86_64 error: 2: no such file or directory
Additional information: 3Two messages above that I expected. However, I made then this:

ALTER database open resetlogs
*
ERROR on line 1:
ORA-01113: file 1 needs media recovery
ORA-01110: data file 1: ' / u02/oracle/stk2proddata/system01.dbf'
This is not what I expected. What I've done wrong? Should I once received the message "cannot open archived log", launched to CANCEL?
I then recovered again, but used
SQL > restore database using backup controlfile until cancel;

No problem then here. Could someone please explain what I did wrong the first time and the second time right? Is this a problem with the car and using CANCEL?

Restore/recovery of database HRCS90 question: psimage2.dbf
People,
Hello. On December 2, 2013, I backed up my instance of database with RMAN with Oracle Linux 5 HRCS90. the backup of the database to run correctly. 2 files 'full_0doqhbqc_13_1' and 'full_0eoqhce9_14_1' are saved in the /backup_database_instance_HRCS90 directory.
Because my HRCS90 database has been damaged, I need to restore the database to HRCS90 until the time 02-Dec_13 when it is saved.First, do not use SET up to THAT. I have run the commands below:
RMAN > CONNECT TARGET;
RMAN > RESTORE database;
The system is in place the error message as below:
RMAN-06956: create the data file failed; Retry after the withdrawal of the /u01/oradata/HRCS90/psimage2.dbf of the OS.
So, I delete the /u01/oradata/HRCS90/psimage2.dbf file and do not have a copy of it.I run RESTORE DATABASE and the psimage2.dbf file is re-created.
The output from the RESTORE DATABASE command is:
Restoration complete, duration: 00:15:54
Finished restore at February 1, 14.
Then I run the following command:
RMAN > RECOVER DATABASE;
Its release: WARNING: media recovery until all SNA 1947113. Finished recover at February 3, 14.Second time, because I need the database prior to 12/02/2013 when she has been saved, I run the command below:
RMAN > RUN {SET until TIME ' to_date (February 12, 2013: 00:04:56 ',' DD-MM-YYYY: HH24:MI:SS') ";} RESTORE THE DATABASE ;}
The commands run correctly and restore complete above.
Then I run the command below:SQL > ALTER DATABASE OPEN RESETLOGS;
His output: failure to change the db command. File 121 was created in the future of incomplete recovery. Data file 121: u01/oradata/HRCS90/psimage2.dbf.
RMAN > RECOVER NOREDO of DATABASE;
Its release: recover command failed. Data file 121 must be restored.
121 data file is the u01/oradata/HRCS90/psimage2.dbf file. I have made sure the directory/u01/oradata/HRCS90/has rwx for all users and groups permissions.
RESTORE DATABASE SET up THAT do not recreate the file psimage2.dbf RESTORE DATABASE while recreate the file psimage2.dbf.I deleted the psimage2.dbf file and cannot resume. I can't find the ORA-1248 by DBPITR article using a current controlfile (Doc ID 1558515.1).
My question is:
Any folk can tell me how to RESTORE/RECOVERY of database HRCS90 with the VALUE up to THAT in other way for example using the file command?
or how to fix psimage2.dbf file that has been deleted by me?
Thanks in advance.
Congratulations! Your database is open so not required recovery (recovery database noredo).
I'm glad that it worked for you. Since you open this database with reset logs, it is recommended that you take a Level0 backup costs.

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

Restore/recovery of database HRCS90 how?
People,
Hello. On December 2, 2013, I backed up my instance of database with RMAN with Oracle Linux 5 HRCS90 as below:
SQL > bootable media. (HRCS database is mounted but is not open.)
SQL > "exit";
[user@linux bin] $. / rman
RMAN > Connect target;
RMAN > configure channel device type disk format ' / backup_database_instance_HRCS90/full_%0_%s_%p'; (backup_database_instance_HRCS90 is the directory to store the backup files)
RMAN > configure retention policy to recovery of 360 days window;
RMAN > set up automatic backup of control file;
RMAN > show all.
RMAN > backup database;
Then database backup is running properly. The 2 files 'full_0doqhbqc_13_1' and
"full_0eoqhce9_14_1" are saved in the /backup_database_instance_HRCS90 directory.
Because my HRCS90 database has been damaged, I need to restore the database to HRCS90 until the time 02-Dec_13. My questions are:
First of all, I have to delete my current instance of the database HRCS90 which is corrupt?
Secondly, I just do the follwing 2 commands one by one to restore the database:
RMAN > restore database;
RMAN > restore database;
Thirdly, the commands above 2 restore database HRCS90 in the 2 files automatically in the directory /backup_database_instance_HRCS90 on December 2, 2013?
Finally, if the above 2 commands are not correct, how do I restore the database correctly on December 2, 2013?
Thanks in advance.
Hello
The control used when retrieving file contains references to files created after CAMILLE.
It is possible to make a DBPITR using a current copy of the control file or a copy that contains files created after the DBPITR. However, some additional steps are necessary to avoid the ORA-1248.
Following article will help you.
ORA-1248 by DBPITR using a current controlfile (Doc ID 1558515.1)

urgent server won't boot up, how rman restore/recovery?
Hello
Reboot server SA will not start server.
s/n cannot access server.
the worst case:
If SA want to rebuild a new server, reinstall the oracle database, is there docs to show me how to restore/recovery of database using rman of rman backup files in the old server records.
(we do not catalog rman, just the control file)
Thank you very much!
If SA want to rebuild a new server, reinstall the oracle database, is there docs to show me how to restore/recovery of database using rman of rman backup files in the old server records.
Yes - there are a LOT of docs on the web. Just use your favorite search engine and the search for them. They are EASY to find.
But the SMARTEST thing would be to find the problem with the original database and fix it.

doubts in the database using backup controlfile recovery.
Hi gurus,
I have a doubt in database recovery using backup controlfile.
I do not speak of "ORA-01207: file is newer than the control file - old control file.
Here, any of our files archive / redo log have been lost and the problem of lack of update in the control file.
So why open the database in resetlogs option, after recovering the database by using a backup controlfile. ?
Thanks in advance
Mahi
In order to maintain the consistency of the data, the RCS should be the same in all the files of the controlfile & file REDO data current.
By definition when you use 'backup controlfile' there a SNA expired in it.
RESETLOG requires the RCS to 1 in order to get consistency across all files in the database.
CREATE CONTROLFILE fills this new file with the most recent SNA that exist in the data files.
It's just the way Oracle has been implemented.

Here's my question after tons of research and test without have the right solutions.
Target:
(1) I have a 12.1.0.2 database unique main enterprise 'testdb' as database instance running on the server "node1".
(2) I created physical standby database "stbydb" on the server "node2".
(3) DataGuard running on the mode of MaxAvailability (SYNC) with roll forward in real time 12 default c apply.
(4) primary database has 3 groups of one-man redo. (/oraredo/testdb/redo01.log redo02.log redo03.log)
(5) I've created 4 standby redo logfiles (/oraredo/testdb/stby01.log stby02.log stby03.log stby04.log)
(6) I do RMAN backup (database and archivelog) on the site of relief only.
(7) I want to use this backup for full restore of the database on the primary database.
He is a DR test to simulate the scenario that has lost every primary & Eve total servers.
Here is how to save, on the database pending:
(1) performance 'alter database recover managed standby database Cancel' to ensure that compatible data files
(2) RMAN > backup database;
(3) RMAN > backup archivelog all;
I got elements of backup and copied to primary db Server something like:
/Home/Oracle/backupset/o1_mf_nnndf_TAG20151002T133329_c0xq099p_.BKP (data files)
/Home/Oracle/backupset/o1_mf_ncsnf_TAG20151002T133329_c0xq0sgz_.BKP (spfile & controlfile)
/Home/Oracle/backupset/o1_mf_annnn_TAG20151002T133357_c0xq15xf_.BKP (archivelogs)
So here's how to restore, on the main site:
I clean all the files (data files, controlfiles oder all gone).
(1) restore spfile from pfile
RMAN > startup nomount
RMAN > restore spfile from pfile ' / home/oracle/pfile.txt' to ' / home/oracle/backupset/o1_mf_ncsnf_TAG20151002T133329_c0xq0sgz_.bkp';
(2) modify pfile to convert to db primary content. pFile shows below
*.audit_file_dest='/opt/Oracle/DB/admin/testdb/adump '
* .audit_trail = "db".
* full = '12.1.0.2.0'
*.control_files='/oradata/testdb/control01.ctl','/orafra/testdb/control02.ctl'
* .db_block_size = 8192
* .db_domain = "
*.db_file_name_convert='/testdb/','/testdb /'
* .db_name = "testdb".
* .db_recovery_file_dest ='/ orafra'
* .db_recovery_file_dest_size = 10737418240
* .db_unique_name = "testdb".
*.diagnostic_dest='/opt/Oracle/DB '
* .fal_server = "stbydb".
* .log_archive_config = 'dg_config = (testdb, stbydb)'
* .log_archive_dest_2 = "service = stbydb SYNC valid_for = (ONLINE_LOGFILE, PRIMARY_ROLE) db_unique_name = stbydb'"
* .log_archive_dest_state_2 = 'ENABLE '.
*.log_file_name_convert='/testdb/','/testdb /'
* .memory_target = 1800 m
* .open_cursors = 300
* runoff = 300
* .remote_login_passwordfile = "EXCLUSIVE."
* .standby_file_management = "AUTO".
* .undo_tablespace = "UNDOTBS1.
(3) restart db with updated file pfile
SQLPLUS > create spfile from pfile='/home/oracle/pfile.txt'
SQLPLUS > the judgment
SQLPLUS > startup nomount
(4) restore controlfile
RMAN > restore primary controlfile to ' / home/oracle/backupset/o1_mf_ncsnf_TAG20151002T133329_c0xq0sgz_.bkp';
RMAN > change the editing of the database
(5) all elements of backup catalog
RMAN > catalog starts by ' / home/oracle/backupset / '.
(6) restore and recover the database
RMAN > restore database;
RMAN > recover database until the SNA XXXXXX; (this YVERT is the maximum in archivelog backups that extends beyond the scn of the backup of the data file)
(7) open resetlogs
RMAN > alter database open resetlogs;
Everything seems perfect, except one of the file log roll forward pending is not generated
SQL > select * from v$ standby_log;
ERROR:
ORA-00308: cannot open archived log ' / oraredo/testdb/stby01.log'
ORA-27037: unable to get file status
Linux-x86_64 error: 2: no such file or directory
Additional information: 3
no selected line
I intended to use the same backup to restore primary basic & helps record traffic and the downtime between them in the world of real output.
So I have exactly the same steps (except STANDBY restore CONTROLFILE and not recover after database restore) to restore the database pending.
And I got the same missing log file.
The problem is:
(1) complete alert.log filled with this error, not the concern here
(2) now repeat it in real time apply won't work since the Party shall LGWR shows always "WAITING_FOR_LOG."
(3) I can't delete and re-create this log file
Then I tried several and found:
The missing standby logfile was still 'ACTIVE' at present RMAN backup was made.
For example, on db standby, under Group #4 (stby01.log) would be lost after the restoration.
SQL > select GROUP #, SEQUENCE #, USE (s), the STATUS from v$ standby_log;
GROUP # SEQUENCE # USED STATUS
---------- ---------- ---------- ----------
4 19 ACTIVE 133632
5 0 0 UNASSIGNED
6 0 0 not ASSIGNED
7 0 0 UNASSIGNED
So until I take the backup, I tried on the primary database:
SQL > alter system set log_archive_dest_state_2 = delay;
This was the Group of standby_log side Eve #4 was released:
SQL > select GROUP #, SEQUENCE #, USE (s), the STATUS from v$ standby_log;
GROUP # SEQUENCE # USED STATUS
---------- ---------- ---------- ----------
4 0 0 UNASSIGNED
5 0 0 UNASSIGNED
6 0 0 not ASSIGNED
7 0 0 UNASSIGNED
Then, the backup has been restored correctly without missing standby logfile.
However, to change this primary database means break DataGuard protection when you perform the backup. It's not accept on the production environment.
Finally, my real questions come:
(1) what I do may not do on parameter change?
(2) I know I can re-create the control file to redo before delete and then recreate after. Is there any simple/fast to avoid the standby logfile lost or recreate the lost one?
I understand that there are a number of ways to circumvent this. Something to keep a copy of the log file waiting restoration progress and copy up one missing, etc, etc...
And yes I always have done no real-time applies "to the aid of archived logfile" but is also not accept mode of protection of production.
I just want proof that the design (which is displayed in a few oracle doc Doc ID 602299.1 is one of those) that backs up data backup works effectively and can be used to restore the two site. And it may be without spending more time to resume backups or put the load on the primary database to create the database before.
Your idea is very much appreciated.
Thank you!
Hello
1--> when I take via RMAN backup, RMAN does not redo log (ORL or SRL) file, so we cannot expect ORLs or SRL would be restored.
2nd--> when we opened the ORL database should be deleted and created
3rd--> Expecting, SRL should not be an issue.we should be able to do away with the fall.

If you do, you can recreate the controlfile without waiting for redo log entry...
If you still think it's something is not acceptable, you must have SR with support to analyze why he does not abandon SRL when controlfile_type is "underway".
Thank you

created a new table called t2 and made sure the data went to a specific tablespace...
has taken a level 0 backup
remove the control file
couple of datafile to above tablespace was added and then insert more data
then went out to restore the database... but datafile and control file always could not be open? What is wrong here...

Restore the backup control file, data files, and archived recovery logs
Recover the database by using up to cancel backup control file
You have to do 'create datafile' bit as the collection hits the 'missing file' bit
You will need to provide the names of the archived and log files online redo recovery reached their

I could do a system backup/restore through the eRecovery without any additional software utility?
I have an Acer Aspire One 532 H Netbook. I could do a system backup/restore through the eRecovery without any extra utility of Windows 7 to Acer recovery? If I have such software, how can I get it? Because my netbook not came with any utility recovery/program when I bought it. Need to respond as soon as POSSIBLE, my netbook is dying with the longer startup time and more.
Nice day
You must back up your data to an external HARD disk, etc. To reload your factory machine, click Start, all programs, acer erecovery management, restoration and completely restore the factory settings.

Recovery using backup Controlfile...
Hi all
I have a little doubt about the recovery process...
Suppose I took a cold backup (after immediate stop).
After that, I started the database, made a newspaper change and delete the control file.
In this case when I try to recover the database by using a backup controlfile (recover database using backup controlfile), I need to provide the name of the log file manually
to ensure no loss of data during the recovery process.
After that, I need start the database with the RESET LOGS.
But my question is why the database will force you to RESETLOGS even if you haven't lost all the data or you haven't made an incomplete recovery.
Thank you...>

It's the RESETLOGS forcing resynchronization of the control file.A control file "backup" is a copy and is supposed to be an older file so it needs to be synchronized with the redo log using RESETLOGS files.
See the doc of SQL language
http://docs.Oracle.com/CD/B28359_01/server.111/b28286/statements_1004.htm

RESETLOGS. NORESETLOGS clause determines if Oracle database resets the current sequence number to 1, archives logs not archived (including the active log) and eliminates any information redo that was not implemented during recovery, ensuring that it will never be applied. Oracle database using NORESETLOGS automatically except in the following specific situations, which require a framework for this clause:You must specify RESETLOGS:

Backup full database, backuing's up controlfile?
Hello
I'm on 8174
is that enough to cold back up the database?
stop immediately;
bootable media;
Run {}
allocate channel t1 type 'SBT_TAPE ';
Send "NB_ORA_POLICY =...";
full backup in format "bk_ %%t U_" (data base);
}
or do I
backup current controlfile;?
I can see here http://download-west.oracle.com/docs/cd/A87860_01/doc/server.817/a76990/rmanconc.htm#436070
This statement "a full backup is different from a full database backup, which is a backup copy of all the data files and the current control file."
is this means
full backup of database, backuing's up controlfile? (I think so) and restoring it requires any archivelogs? (I think not)
Thank you very much
Published by: user9145417 on August 25, 2010 16:42Yes, you will need to take backup of the backup control file.

Hello
I'm practicing controlfile conecpts backup and restore. In a database, there are 3 controlfiles. I have a copy of database backup controlfile and archivelogs. I deleted a controlfile.
There is no message in the alerts log. I get an error only when I have as long as DBA question certain points of view V$. I get a message that a controlfile does not exist, no file or directory etc. etc.
The interesting thing I have noticed is that I get no error when querying V$ views already recorded sessions until I removed controlfile. I get error only when I connect to a new session and the query V$ views.
Is there a way DBAs do we know if a controlfile has been deleted at the OS level other than this way? How DBAs usually knows a controlfile is missing?1.
Instance crashes whenever there is an error in the reading or writing of control file. Reading and writing are not a continuous process. So after deletion, you have to wait a bit for the next operation. If you do not want to wait just trying to make the point of control, add/delete datafile or empty manually.2.
RM command really does not remove the files. For fiscal purposes use shred or dd to put some of 0 and 1 in file. If the control file is not valid, its effect will be the same.3.
The number of user sessions / is not serious.Bartek

Is it possible to restore your computer to factory without a backup requirements?
I restored my computer using my sisters backup disks and I was just wondering.
Hello
In regards to what they actually do, there not much in it--a "Factory Reset" from the disk is normally faster than using recovery discs.
The main advantage of having a set of recovery disks is that they will allow you to reinstall Windows 7, if the recovery Partition corrupted or the HARD drive had to be replaced.
OEM recovery disks validate the installation by reading a "tattoo" on the bios chip, but as you know that your sisters drives work well on your machine, you can always create a duplicate for yourself the value as follows.
Download and install the free software ImgBurn.
1. create an Image file disc the 1st disc of recovery on your laptop - a guide for doing this is here.
2 write this on a blank DVD Disk Image - a guide to it's here.
3. Repeat for each subsequent until you have a complete set.
Kind regards
