Path to redo logs after restoring of controlfile
Hello!
After restoring of controlfile I see distorted redo logs metadata (column v$logfile.member ) :
$OH/dbs/data/ora/MY_SID/rlog/redo1a.logIn source database redo logs placed in other directory,
also I should drop logfile members and logfile groups and then to create them again , but may be there is other way to fix this issue?
Please advise.
I'm usung 11.2.0.3
Thanks and regards,
Pavel
Hello Grirsh
Thank You.
You mean you are having some other name of redolog files than in the folder ?Yes , You are right. In database never was redo with this path.
If yes, it means they may be something else, because Oracle is just using the those files which are showing in column of member of v$logfile view.Sorry. Could I ask You please to explain this phrase, as I wrote In database never was redo with this path,
from where they appear after restoring of controlfile ?
I saw the binary file from which control file was created through browsers, it doesn't contain the path mentioned in my first post
Best regards,
Pavel

INVALID redo log after creating a new group member
Hi all,
I've just followed instructions to create a new redo log file member:
alter database add logfile member '/oracle/mplex/redo/redo01b.log' to group 1;
When I query v$logfile, the status is INVALID though.
SQL> select * from v$logfile where group# = 1;
GROUP# STATUS TYPE
MEMBER
IS_
1 ONLINE
/u01/app/oracle/oradata/redo01.log
NO
1 INVALID ONLINE
/oracle/mplex/redo/redo01b.log
NO
the oracle user owns the mplex directory and permission are fine
[oracle@redo]$ ls -ltr
total 51260
-rw-r----- 1 oracle oinstall 52429312 Mar 11 11:55 redo01b.log
Any ideas?
Thanksconnect to the database again as a sysdba, and run
sql> alter system switch logfile;
Run this command again.
select * from v$logfile where group# = 1;

RMAN-03008 and ORA-07217 after restore of controlfile, 11.2.0.2
Hi,
try to restore backup done with 11.2.0.2
because upgrade to 11.2.0.3 has problems with workspace manager,
- done with DBUA - which is a other part of the story.
OS is SLES11SP1 x86_64
Here is what happens:
startup nomount with minimal pfile in 11.2.0.2 environment
restore controlfile from SBT
channel T1: restore complete, elapsed time: 00:01:45
output file name=+DSKGRP1/alkklefq/controlfile/control01.ctl
output file name=+DSKGRP1/alkklefq/controlfile/control02.ctl
then
RMAN> ALTER DATABASE MOUNT;
database mounted
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03008: error while performing automatic resync of recovery catalog
ORA-07217: sltln: Umgebungsvariable kann nicht ausgewertet werden.
No other command like show all, resync catalog or what ever is working,
always fails with RMAN-03008 and ORA-07217
and after
run {
allocate channel T1 type 'SBT_TAPE' format 'b_%d_%u_%p_%c.bck';
restore database from tag 'TAG20120730T212808';
i got

Can anyone throw light on this?
Regards
MichaelHello;
Based on the information you probably I would double check my "env" for an issue. Something set wrong or not set.
Does the "env" work without error?

Applying Archive logs after restore by RMAN
We user RMAN for our backup. I wanted to restore the database and apply all the archive logs.
After I use
RMAN> Restore database ( from last night backup)
RMAN> Recover database
And now I want to apply all the archive logs from which were generated from last night backup say 11:00 pm till 10:00 am today morning.
How can I apply the archive logs.
ThanksI have the RMAN backup on tape , and I have the archive logs on the disk , as the archive logs would be backed up only the following night.
i.e i want to restore a 10th night backup , and apply the logs from 10th night 11:00 pm to 10:00 am 11th morning. As the archive logs would still be on the disk , how can I apply them..
Thanks -
Db restore non archive mode lost redo log file..restore from controlfile tr
i have a db 11g I had taken non archive backup but failed to take redo log files backup...
so while i restored the db ... after formatting the machine ..the oracle instance wont start.

Edited by: zycoz100 on Feb 27, 2013 10:57 PMIf you have a cold backup (database shutdown properly) without the redo logs, change this :
CREATE CONTROLFILE REUSE DATABASE "XE" NORESETLOGS NOARCHIVELOGto
CREATE CONTROLFILE REUSE DATABASE "XE" RESETLOGS NOARCHIVELOGYou have to change the NORESETLOGS to RESETLOGS for Oracle to recreate the online redo logs.

Please help me how to execute for the above query.
Thanks,
HariharanHello
Complete step:
Step 1 SQL> select a.group#, a.member, b.bytes/1024/1024 mb from v$logfile a, v$log b where a.group# = b.group#;
This query will show current group with redo log members and their size.
Step 2 Make the last redo log CURRENT one
To find which group is current at this moment use following query
SQL> select group#, status from v$log;
GROUP# STATUS
1 CURRENT
2 INACTIVE
3 INACTIVE
4 INACTIVE
Now as you can see that the first group is marked as current but we need to make group 4 as current. So force group 4 to become current one by switching log file. To switch log file use following query.
SQL> alter system switch logfile;
GROUP# STATUS
1 INACTIVE
2 CURRENT
3 INACTIVE
4 INACTIVE
SQL> alter system switch logfile;
GROUP# STATUS
1 INACTIVE
2 INACTIVE
3 INACTIVE
4 CURRENT
Step 3 Drop the first online redo log
After making the last online redo log file the CURRENT one, drop the first online redo log:
SQL> alter database drop logfile group 1;
Database altered.
Note:
Be aware that if you are going to drop a logfile group, it cannot be the current logfile group. However, where attempting to drop the logfile group resulted in the following error as a result of the logfile group having an active status:
SQL> ALTER DATABASE DROP LOGFILE GROUP 1;
ALTER DATABASE DROP LOGFILE GROUP 1
ERROR at line 1:
ORA-01624: log 1 needed for crash recovery of instance ORA920 (thread 1)
ORA-00312: online log 1 thread 1: ''
Easy problem to resolve. Simply perform a checkpoint on the database:
SQL> ALTER SYSTEM CHECKPOINT GLOBAL;
System altered.
SQL> ALTER DATABASE DROP LOGFILE GROUP 1;
Database altered.
Step 4 You need to re-create dropped online redo log group with different size. Use the following query to achieve this.
SQL> alter database add logfile group 1 ('<path>/origlogA/log_g11m1.dbf','<path>/mirrlogA/log_g11m2.dbf') size 200M reuse;
Database altered.
Step 5 Force another log switch
After re-creating the online redo log group, force a log switch. The online redo log group just created should become the "CURRENT" group:
SQL> select group#, status from v$log;
GROUP# STATUS
1 UNUSED
2 INACTIVE
3 INACTIVE
4 CURRENT
SQL> alter system switch logfile;
SQL> select group#, status from v$log;
GROUP# STATUS
1 CURRENT
2 INACTIVE
3 ACTIVE
Step 6 # Loop back to Step 3 until all logs are rebuilt
After re-creating an online redo log group, continue to re-create (or resize) all online redo log groups until all of them are rebuilt.

hi, i want how can resize redo log size,
i have try resize redo log file following way
1] first i have my redo log size is
GROUP# STATUS MEMBER SIZE
3 ONLINE /oradata/xyz/redo03.log 100M
2 ONLINE /oradata/xyz/redo02.log 100M
1 ONLINE /oradata/xyz/redo01.log 100M
I want this size is reducing , i have try following way
1] first i have create GROUP 4 add member
ALTER DATABASE ADD LOGFILE GROUP 4 ('/oradata/xyz/redo04.log') SIZE 30M;
then
alter system switch logfile;
in this way i have create remaning two redo log,
after create i have delete old redo log, is is correct method for reducing redo log.Check Note: 1035935.6 - Example of How To Resize the Online Redo Logfiles
https://metalink.oracle.com/metalink/plsql/ml2_documents.showDocument?p_database_id=NOT&p_id=1035935.6 -
Hi! May I ask you a question... B-)
Sybex OCA guide. page 506 8th line:
A redo log file records all changes to the database in most cases before the changes are written to the datafiles.in wich cases rocordes are written to the redo logs after/during chanches in the datafiles? X-(
thanks in advance. :DStrictly speaking both "all operations with nologging clauese" and "operations on objects which are in nologging state" are incorrect.
You may put a NOLOGGING clause in an operation but find that it still does Logging. (eg if you put a Hint "APPEND NOLOGGING" on a Logging table, the INSERT is still logging because the "NOLOGGING" is not a valid hint and is ignored. Similarly if you put a CREATE TABLE ... AS SELECT * FROM .. NOLOGGING; also the NoLogging is ignored because it is invalid).
Similarly, you could set a table to NOLOGGING but all regular DML will still be logging.
Therefore, only operations that support NOLOGGING will be nologging. -

SubbuHello Subbu,

You mean you have taken an online backup and lost all your archive log files after that online backup?

To perform a recovery with an online backup you will need all archive log files until the end of the online backup. If you have lost them you are not able to recover (or open) your database in a consistent state.
So the only suggestion we can do is:
You need the archive log files that were created during the online backup to perform an incomplete recovery ... if they are gone you can not restore your database.

How Do I Restore Deleted Redo Logs
I currently have alter database archivelog set and am backing up my archive log redo file. However, I am trying to test a scenario where all of my redo log files have been deleted, and thus need to be restored. I have backups of my archivelog files. I'm trying to recover my redo log files by executing the following:
RMAN> restore archivelog all;
Starting restore at 14-AUG-02
allocated channel: ORA_DISK_1
channel ORA_DISK_1: sid=9 devtype=DISK
archive log thread 1 sequence 102 is already on disk as file C:\ORACLE\ORA90\RDBMS\ARC00102.001
archive log thread 1 sequence 103 is already on disk as file C:\ORACLE\ORA90\RDBMS\ARC00103.001
archive log thread 1 sequence 104 is already on disk as file C:\ORACLE\ORA90\RDBMS\ARC00104.001
restore not done; all files readonly, offline, or already restored
Finished restore at 14-AUG-02
Since this doesn't work I'm assuming I'm doing something wrong. Therefore, what are the necessary steps for recovering my redo log files after they have been deleted? Thanks to all for your help.Since my test assumes that the Control files, redo logs and all tablespaces and data files have been deleted. These are the steps I'm using to attempt a full backup & recovery.
3. Login to SQLPLUS sys/jalisco@bas as sysdba
4. SQL> startup mount bas <enter>
5. SQL> alter database archivelog; <enter>
6. Stop the Listener and Instance through Services or Net Stop as before.
7. From a command enter C:\Oracle\startoracle jalisco bas.
8. Login to RMAN: rman target sys/jalisco@bas <enter>
9. RMAN> configure controlfile autobackup on; <enter>
10. RMAN> backup database format
a. 2> /oraclebackup/rman_%d_%t.bas plus archivelog; <enter>
At this point Oracle is configured so that both the archivelog and control files get backed up to oracle\ora90\database. The archivelogs get stored in oracle\ora90\rdbms.
1. Restore the control files.
2. Restore the archivelogs.
3. Restore the tablespaces and data files.
4. Create new reset logs.
1. Confirm that the Listener and BAS service have been started through the Contol Panel, or by using Net Start.
2. Login to RMAN: rman target sys/jalisco@bas as sysdba
3. RMAN> startup nomount
4. RMAN> restore controlfile from /oracle/ora90/database/C-493922189-2002MMYYYY-00;
5. RMAN> startup mount
6. RMAN> run {
a. 2> restore archivelog all; }
7. RMAN> restore database;
8. Exit RMAN and Login to SQLPLUS sys/jalisco@bas as sysdba
9. SQL> alter database open resetlogs;
At this point I get the error which is listed in the above thread.
At this point a complete recovery should have taken place. It is extremely important to create a new backup now before proceeding. -
Restore in noarchivelog mode ( redo log files have been dropped )
1, A full backup taken using RMAN is available on disk.
2, The current control files were NOT damaged and do not need to be restored.
3, All data files are damaged .
4, The database is in NOARCHIVELOG mode.
I restore database :
1. RMAN> STARTUP MOUNT
2. RMAN> RESTORE DATABASE;
3. RMAN> recover database;
in this step , I got the information about needing redo log files ; but the redo log
files have been dropped , what should i do ?
else
I want to know there is the command 'recover database using backup control file'
in rman or not ?
TksPossibly loss of data (because information in online redo logs is lost):
recover database until cancel;
(cancel immediately)
alter database open resetlogs; (to build a new set of redo logs)
It's not necessary to use a backup controlfile here. -
Restoring archive log after cold backup
Hello forums users,
I read many thing on this topic but I didn't find the good answer.
I performed a cold backup each sunday.
My database is in ARCHIVE LOG mode.
Is it possible to restore ARCHIVE LOG files after restoring COLD backup?
Sunday : cold backup
Monday : new archive log have been created since cold backup
Tuesday : same as Monday
Wednesday : I would like to restore to Monday 22:00 for example
Can I restore cold backup + apply archive log until Monday 22:00 ?
Regards,
Guillaumerecover database using backup controlfile until cancel|time|logseq|scn
will do this and prompt you for the archivelogs.

Recover database without controlfile and redo logs
Hi guys,
I am doing a testing with an Oracle Database 11.1.0.7.0, I want recover a database in this scenario without using RMAN:
-All controlfiles are missing
-All redo logs are missing
-I have a Backup Controlfile To Trace Resetlogs (bkp_controlfile.sql)
-The database is in archivelog mode
-The database was created with OMF (Oracle Managed Files)
So I have done this steps:
1) When the database was opened I rename all controlfiles and all redo logs
2) Shutdown Abort
3) I run the bkp_controlfile.sql, here I have a problem...
The database put in NOMOUNT, the controlfile was created and started the RECOVER DATABASE USING BACKUP CONTROLFILE, but when run ALTER DATABASE OPEN RESETLOGS; appear this:
ERROR at line 1:
ORA-01113: file 1 needs media recovery
ORA-01110: data file 1:
'/u02/app/oracle/oradata/OMF/datafile/o1_mf_system_68hzcb2z_.dbf'I wasn´t expect this because I don´t want recover a datafile, I only want open with resetlogs.
Any suggestion to help me?
Thanks a lot.Excelent! Thanks for your answers Markus and Hemant.
In conclusion...
- If we have all redo logs availables we can recreate the control file and recover the database without any problems using backup controlfile to trace noresetlogs*.
- if we haven´t all redo logs availables, there are 2 situations:
1) If the database shutdown properly:_ We will be able to open the database using recover database using backup controlfile until cancel*.
2) If the database doesn´t shutdown properly:_ We won´t be able to open the database with only a backup controlfile to trace.
With all this I close this thread. Was very good experience.
If anyone would add something will be welcome.
Thanks for all
I wish add the results of one of my tests: if I did all the steps in only one session of sqlplus I can shutdown properly the database, but if do the shutdown immediate* in a new session I can´t shutdown properly the database. Here I post the output:
ALL IN ONE SESSION*

After increasing redo log groups we are getting given alerts continvously
earlier having 6 redo log groups with 32 MB.but 7 days back our database was hangs .no one was able to login into sqlplus except sys user ,but not able to perform any dml operation.after rebooting our 2-node RAC instances it was running fine nearly about 6-7 hrs and again hangs.we did 4-5 times and same thing happend again and again.so we had added more redo logs of 100 MB size and removed previous one.then our hangs problem resolved but continvously getting given things in alert logs for both RAC instances(9.2.0.8).our os is linux

please suggest solution for this.
ThanksAs Sybrand pointed out, this msg can be ignored. It clearly states that a given arch process cannot archive a given redo because that redo is already being handled by a different arch process. If you follow your alert log a little further, you'll see that the referenced thread is eventually completed.
I'd be curious to see the alert log from when you were locked up and only sysdba could log on. See what led you to believe that adding more redo log groups would solve your problem. -
Corruption of archived logs after redo resizing - URGENT
Hello all,
We have a RAC 9i 2-node DB, running on RHEL 3 machines.
We resized our redo logs from 100M to 1G to avoid "Can not allocate log, archival required" messages.
The operation was successful, but now we are facing problems with the ext3 filesystem holding the archived logs.
Each node has its own arc location, mounted only once.
When we run "ls" in the arc destination, we get "ls: Input/output error" messages.
RMAN complains also about corrupted arcvhived logs.
The day before Yesterday we reformatted one arc destination, and today the messages appeared in the other one.
Do you have any suggestion?
JonathanDid the problem occur right after increasing the log size? Then the first thing to do would be to decrease the log size, but add more log groups to fix the "Can not allocate..." problem.
If "ls" doesn't work, your file system is stuffed.Reformat the archive dest and do simple file copies to verify the integrity, before putting the archive logs back on.
That's just for starters...
