RMAN-06054: media recovery requesting unknown log: thread 1 seq 300 lowscn
Got it dropped and recretaed - dont know why didnt work
Edited by: user3489571 on 14-Apr-2010 18:46
The ALTER DATABASE REGISTER LOGFILE command in SQLPlus is for Standby and Streams implementation.
You should be using the CATALOG command in RMAN.

RMAN Restore Error - media recovery requesting unknown log: thread 1 seq 7
Im using RMAN to copy a database to another server. The new server is IDENTICAL to the old one. By identical I mean it has the same sever name, ip address, operating system, Oracle version and directory structure.
The new server already has the instance created, (same name as the old server instance, paths etc)
The backup files have been manually restored to the new server, same locations as they were on the old one. ( RMAN did an automatic controlfile backup and also the archivelogs on the old server ).
Ive restored the control file on the new server from the RMAN backup pieces.
Ive catalogued the RMAN backup pieces on the new server.
I know the last sequence available in the archivelogs backup by running on the new server :
list backup of archivelog all;

So far its all going swimmingly well.
Now I want to restore the datafiles and recover. So I ran :
RMAN run { restore database; recover database; alter database open resetlogs; }
This gave me the output below which goes great but I get a final error, I think the error is because its looking for an archive log thats not in the backup set, but it should be. However, I think SCN 560851 is for a log that hadnt been created yet on the old server when the backup was ran ?
How do I address resolving the error ? Its worth pointing out log, "archive log filename=C:\ORACLE\PRODUCT\10.2.0\FLASH_RECOVERY_AREA\SAT\ARCHIVELOG
\2011_05_11\O1_MF_1_6_6WOK1X4W_.ARC recid=10 stamp=750881741" isnt on the old server either which is why its not in the backup set.
I can do a alter database open reset logs but Id prefer to know why its failing.
Any help would be much appreciated.

Edited by: user12173666 on 11-May-2011 10:28You need to do incomplete recovery i.e. to ask RMAN to restore/recover to some specific point in time. This is usually done with some UNTIL clause or SET UNTIL statement. Example in your case:

In the first case, just specify SCN or find the actual log file and speficy log sequence, instead of time. In the latter case, remove the old restored files or speficy noresume.

Standby media recovery waiting for inactive thread
Hi,
Please let me know any idea on this scenario. Thanks.
Environment:
Oracle 11.2.0.2
primary: 3 node RAC
standby: 3 node RAC
Problem:
there is thread 5 (not registered instance or did not show in srvctl) that generates archivelog. but the lag apply stopped because of this when the instance (of thread 5) is shutdown.
question: somehow an instance is registered in the cluster but in srvctl only 3 instance is running. it should have 4 instance but 1 is not running. How can I remove the thread 5 so when someone startup then shutdown instance#4 it will not create archivelog that will stopped the apply of archivelog in standby.
note: this is perf environment server so someone and "other" DBA is accessing this environment which I am not aware what are they doing with the cluster.
looking in alert log file: - it is waiting for thread 5 sequence 510. But the instance is down so log is not shipped to standby database and this resulted to lag in other threads.

Hi,
I get the error "Error : RMAN-06054" when I try to recover a full database backup.
The backup command used was:
BACKUP DATABASE PLUS ARCHIVELOG;
In my tests, when I dont remove the ONLINE redo log files the recovering works OK!
I use auto backup controlfile configuration.
Thank you,

RAC instance, trying to recover UNDO datafile, RMAN gives RMAN-06054
Hello all,
This has been a troublesome instance..a quick bit of background. This was created awhile back by someone else, I inherited this 3 mode RAC clusterof instance1.
I'm exporting out of one database (10G) into this instance1 (11G). When I was about to start the import..I found this instance wouldn't start. Turned out no backup had been going on of this empty instance. I backed up the archive logs to tape to free up the FRA..and things fired up.
I began the import, and found a bunch of errors...basically tellling me that I couldn't access one of the undo tablespaces...datafile problems.
I went to look and saw:
SQL> select a.file_name, a.file_id, b.status, a.tablespace_name
2 from dba_data_files a, v$datafile b

RMAN-06054: media recovery requesting unknown archived log for thread 1 with sequence 1 and starting SCN of 16016
This is all on ASM, and am a bit of a newb with that. I bascially have no data I'm worried about losing, I just need to get everything 'on the air' so I can import successfully, and let users on this instance. I've set up the backups in GRID now....so, it will be backed up on the future, but what is the quickest, most efficient way to get this UNDO tablespace datafile recovered?
Thank you,

Hemant K ChitaleOops...meant to have start and set until both to "1"
However, I see what you mean. It seems I cannot find the file on tape.
Since the RAC instance hasn't yet had any data put into it, I'm thinking it might be best to just blow it away, and recreate everything.
Trouble is, I'm a bit new at RAC and ASM. I was thinking the best route might be to use DBCA to remove the database...? Would this not take care of removing all the datafiles from all the ASM instances on the RAC..as well as all the other directories, etc on all 3x nodes?
I've already used the dbca to create templates of this instance, so recreation shouldn't be too difficult (although it will be my first RAC creation)...
Thank you in advance for the advice so far,

Media Recovery Waiting for thread 1 sequence (in transit)
I have rebuilt our standby database using an rman duplicate since it was missing many archive logs.
Following the duplicate, the standby is now almost in sync with the primary. Logs are shipping across but are not being applied in a timely manner. How long should it take for an archive log from the primary to be applied to the standby?
I need to know this so that a proper script can be set up to check the primary and standby. At the moment they are never exactly in sync - always one sequence number behind the primary.
Why is the standby is not applying in a timely manner?
From the alert log:

Media Recovery Waiting for thread 1 sequence 11278 (in transit)
I should add that I understand that for the Primary and Standby to be out by one log is not cause for concern (they are applying). Its just that I wanted to script a check that would compare them both, and and the moment they are never equal - when I understand that they should be and that the logs should be applied almost immediately.
Edited by: Dan A on Nov 1, 2010 4:36 PMHow long should it take for an archive log from the primary to be applied to the standby?depends on network speed also.
make sure the archives are shipped to standby location.

Hi check is MRP started or not?
primary database you need not check current sequence, check last generated sequence..not current sequence.
current sequence is redo log which has been not yet archived
I think everything is perfect here.. no issues.
Hope you understood, let me know if not clear , thanks. -

Block Media Recovery and RMAN Incremental Level 1 backup
Hi
I have read somewhere that Block Media Recovery will not work if a database is backed up using rman incremental 1. Is this true, and if so is there a work around?
I cannot seem to find this in oralce's documentation.
Regards
MeHi,
1) is Full Backup = Incremental level 0 backup?
Yes
2) When oralce say BMR does not work with incremental, will it work in the case I put forward. becuase Im doing an incremental 0...
But does you have the Archive logs available.. ?? If yes then it will Support.
3) Im my case will BMR work...that is use Incr level 0 on Sunday and then use archive logs for mon, tues etc
Yes, I believe.
@Hemanth .. am I right.. ?? Wait for your inputs...

ARC0: media recovery disabled
What is Wrong wiht my Oracle?This problem occurs because an archive process has been started but it has nothing to do because the database is in NOARCHIVELOG mode. This could be rather serious if it is expected that the database runs in ARCHIVELOG mode.
This happens when only log_archive_start = true. Which means an archive process is started on database startup, but because the database is not actually in archivelog mode, the archiver reports the above message.
To verify use v$database view. The LOG_MODE is NOARCHIVELOG even though log_archive_start = true.
Put the database in archivelog mode:
1.1. Mount the database.
1.2. Issue the command: ALTER DATABASE ARCHIVELOG;

How to do media recovery from cold backup?????????/
Hi
i take cold backup of my 9i database ....
in case my database is up .....
how will i recover my database if i lose a single database file and i want to recover it from cold backup......
Thanks in advance
GaganHere you go
These are the steps:
1. Restore the lost file from a backup.
2. If the database is down, mount it.
SVRMGR> STARTUP MOUNT PFILE=<location_of_pfile>;
3. Issue the following query:
SVRMGR> SELECT V1.GROUP#, MEMBER, SEQUENCE#,
FIRST_CHANGE#
FROM V$LOG V1, V$LOGFILE V2
WHERE V1.GROUP# = V2.GROUP# ;
This will list all your online redolog files and their respective
sequence and first change numbers.
4. If the database is in NOARCHIVELOG mode, issue the query:
SVRMGR> SELECT FILE#, CHANGE# FROM V$RECOVER_FILE;
If the CHANGE# is GREATER than the minimum FIRST_CHANGE# of your logs,
the datafile can be recovered. Just keep in mind that all the logs to
applied will be online logs, and move on to step 5.
If the CHANGE# is LESS than the minimum FIRST_CHANGE# of your logs, the
file cannot be recovered. Your options at this point would be to restore
the most recent full backup (and thus lose all changes to the database
since) or recreate the tablespace as explained in scenario a.
5. Recover the datafile:
SVRMGR> RECOVER DATAFILE '<full_path_file_name>'
6. Confirm each of the logs that you are prompted for until you receive the
message "Media recovery complete". If you are prompted for a non-existing
archived log, Oracle probably needs one or more of the online logs to
proceed with the recovery. Compare the sequence number referenced in the
ORA-280 message with the sequence numbers of your online logs. Then enter
the full path name of one of the members of the redo group whose sequence
number matches the one you are being asked for. Keep entering online logs
as requested until you receive the message "Media recovery complete"
7. If the database is at mount point, open it. -

Any idea ?
Thanks.here is one test case, i ran into same issue. and reolved as below.
When Standby_file_management is set to “MANUAL” , if any data files added on primary database, These changes certainly won’t be altered in standby database.
After starting MRP process, it dies and terminated with the following errors.
Errors from Alert log file:-

Check out from SQL, Which files need to be recovered on standby database?
SQL> select * from v$recover_file where error like '%FILE%';
FILE# ONLINE ONLINE_ ERROR CHANGE# TIME
+536 ONLINE ONLINE FILE MISSING 0+
SQL>
On Primary check out for actual naming convention:-
SQL> select file#,name from v$datafile where file#=536;
FILE# NAME
+536 DATA/c/datafile/undotbs9.595.750444337
SQL>
On Standby check datafile name:-
SQL> select file#,name from v$datafile where file#=536;
FILE# NAME
+536 /oracle/app/oracle/product/10.2.0/db_1/dbs/UNNAMED00536+
SQL>
Make sure still standby_file_management is set to “MANUAL”, After performing media recovery again can be enabled to “AUTO”.
Rename datafile from standby database:-
SQL> alter database create datafile '/oracle/app/oracle/product/10.2.0/db_1/dbs/UNNAMED00536' as 'DATA3/cc/datafile/undotbs9_595_750444337';+
Database altered.
Start the MRP Now:-
SQL> alter database recover managed standby database disconnect from session;
Database altered.
After creating the file, MRP will start applying archives on standby database.
