Hai all,
In note id , 232240.1 - Performing Switchover in a Data Guard Configuration
Convert the physical standby to the new primary:
If you are on verion 9.0.1 then you should first cancel managed recovery prior

SQL*Plus auto accept CANCEL during recovery

I am scripting out to do an incomplete recovery with a backup controlfile.
How do I get SQL*Plus to automatically accept "CANCEL"
when I get to this point: Specify log: {<RET>=suggested | filename | AUTO | CANCEL}
and then move on to "alter database open resetlogs"

You can't - that's the whole point behind incomplete media recovery - how does sqlplus know when you want to cancel

Can't Cancel the Process Of Media Recovery Creation and Start A New One

help me cancel the process of media recovery creation and start it all over again because i found that i need four disks to make the recovery creation. i made the first disk but i need to get another three disks for the process to be completed. It says that "media recovery creation has not been completed", so i want to cancel the whole opeation and start from the beginning later when i am ready for it. How can i do that, any steps or instructions to solve this issue would be appreciated.

You can only create one set of recovery discs. So once the process is completed, you will not be able to create another.

Oracle Media Recovery Not Started

Hi,
Need help
I've just performed system copy in HP-UX & Oracle as database using backup restore method.
I'm using online backup for this system copy. Control file has been created successfully. Now I'm trying to start the media recover using below cmd
"recover database using backup controlfile until cancel"
After applying this command system is not starting the media recovery. From alert log file I can see the msg Media Recovery Start but oracle is not giving any further message, it is stuck on the below screen.

Regards,
Neehir Bhatt

Hi Neehir,
How did you create the control file ?
Did you use start the DB with source SID and generated a control file trace and then excutede the control file trace sql with the SID change in ordrer to create actual control files with ORACLE_SID reset to actual DBSID. .
Also i use:
recover database until cancel using backup controlfile;
and not :
"recover database using backup controlfile until cancel"
Not sure though if that should make difference because if yours was erroneous oracle should have let you known.
What message comes when you try
alter database open
Regards.

Cancel based recovery

dear dba's,
i'm using oracle 11gR2 in windows 2003 sever S2.
could anyone tell me
1. what is CANCEL BASED RECOVERY
2. pls give the commands with an explanation
3. In which suituation we must use this type of recovery.
Thanks & Regards,
John Marshal.A

+1. what is CANCEL BASED RECOVERY+
It is an incomplete recovery option , at particular time you want to recover yours database for an audit purpose or to avoid any logical error by users in past , but flashback technology now been dominant to cancel based reocovery.
+2. pls give the commands with an explanation+
+3. In which suituation we must use this type of recovery.+
When yours controlfile does not know when so far yours recover could be go on and on by "recover database using backup controlfile until cancel" yours restored controlfile from backup typically does not know how far i need redo if you are doing manual recovery while RMAN does not need cancel based recovery it will keep applying log until it finds and bumped out with an error RMAN-06054: media recovery requesting unknown archived log for ..... .
Situation could be manual recovery in general when you do not define time.scn based recovery using until clause.
Copied from my blog but need to be a bit changes thats why pasting here.
Scenario 1
I lost all data file but my control file is intact at the same location where it was , before lost datafiles i have backed up the data files, controlfile and archive logs.
If you are just restoring the data files and not control files then you may know how much archive log sequence required for yours recovery after the backup taken using archived log repository.

as you can see that 2,3,4 were required during recovery process.Scenario 2
I lost all data file as well control file , i have backed up the data files, controlfile and archive logs.
Its like a disastre you lost alls data file and as well controlfile , if you backed the controlfile then remember during controlfile backup it will have file type flag 4 that tells Oracle it is a backup control file. The Stop SCN for alls data file marked to 0xffff.ffffffff (infinity).File type flag in the backup control file tells to oracle that it cannot rely on its redo thread,which means recovering will go on and on , controlfile will not aware how much should i go for redo it will never stop if you are able to supply redo.
It will always ask you more subsequent redo if you already supplied to it during process that's why it let you open the database in reset logs.
Lets see after restoring the controlfile and datafiles , you will see SQL tool recovery mechanism ask you recover database using backup controlfile which shows that controlfile does not know where to end the applying redo chain.
Here an excerpt which shows that restored controlfile does not know till how long the redo should be applied, its the RMAN robustness which does not ask you manually to supply redo, RMAN search the alls redo from archivelogs and if possible you have redo within redo logs.But if you are not with RMAN i.e recovering by SQL then you have to cancel recovery at some end.

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 :

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 10:28

You 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:
SET UNTIL SEQUENCE 7;See http://download.oracle.com/docs/cd/B19306_01/backup.102/b14194/rcmsynta065.htm#RCMRF160.

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
Gagan

Here 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.

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)
The log seems to be "in transit" for a long time

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.

How 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.
PRIMARY:
SQL> select max (sequence#) current_seq from v$log;

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.

In addition to what was said, I can think of two other possibilities for RMAN-6054 during duplicate: bugs such as 12625205 (also see 8554110); duplicate was run earlier without removing the old restored files (Note 1549172.1). 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.

"needs media recovery" after a successful recovery ???

RMAN novice here....
Oracle 9.2.0.1.0 on Redhat Linux (Itanium)
Running in NOarchivelog mode
In RMAN, I backed up a set of datafiles in read only mode taking this approach....
sql "alter tablespace foo read only";
configure channel 1 device type disk format 'backupdisk/mybackuparea/foo.dbf.bck';
backup datafile 'dbdisk/mydb/foo.dbf';
sql "alter tablespace foo read write;
Everything seemed to go fine.
After some time, I wanted to restore/recover. This is what I did (again, in RMAN"...
sql "alter fablespace foo offline";
restore datafile 'dbdisk/mydb/foo.dbf';
recover datafile 'dbdisk/mydb/foo.dbf' noredo;
sql "alter tablespace foo online";
My first stab at it, without the "noredo" failed. But with the "noredo" I got
"Starting recover at ...."
A set of channel assignment statements
"Finished recover at ..."
Looks to have run OK.
But then, when I try to put the tablesopace back online...
"failure of sql command on default channel at...."
"failure during parse/execution of SQL statement: alter tablespace foo online"
"file 1 needs media recovery"
"data file 1: 'dbdisk/mydb/foo.dbf'"
What gives?
Thanks for any help

I've read the books and googled this to death.
Looks like I'm screwed.
At this point, I don't even care about the datafile or the tablespace it contained. I just want my database back.
I dropped the tablespace and it's datafile (and it's data too). I'll have to repopulate from scratch.
Lesson learned
This is what I want to do.....
I want to do a 1x/wk backup of a schema (not the whole DB, I don't have enough disk space for that, just 1 of the schemas). I've designed the thing such that each schema has it;s own tablespaces (no overlap) and each tablespace maps to a single datafile.
I would have liked to do some sort of online backup of the schema (read/write while backup is happening), but I'll settle for read only. If Oracle can't hack that, then I'll take the tablespaces offline.
The schema contains hundreds of millions of records, and the load preocess involves several times that number of data manipulation statements (deletes, updates, inserts). I'd rather not use archivelog mode because I don't have the disk space for it. And, given the volume and nature of the data I'm loading (hundreds of millions of records, created from the data in large raw data files), and how it's being loaded (precompiled C/SQL programs), I would never have need to "rerun" the enormous archives for any reason.
So...
1) backup a single schema (an exclusive set of tablespaces/datafiles)
2) as "online" as possible
3) in noarchivelog mode.
The only thing that I've seen that can do this is EXPORT/IMPORT. I tried that, but extrapolating IMPORT performance, even with all the streamlining recommendations, would take over 3 days. For this reason, IMPORT is not a viable option.

Media Recovery failed with error 1111

Hi,
on 10g R2 on Unix I have :

Fri Jun 24 10:56:52 2011
Media Recovery failed with error 1111

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.

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:-

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.

Media recovery issue

Hello
Why is media recovery is faster than, normal DML,DDL,etc?
In production database, It took 1 hour to rebuild indexes and move some objects to diffrent tablespace.
However, When I apply the archivelog of these changes to standby, it took about 20 minutes.
What is reason for this?
Cheers

Media Recovery / Physical Standby operations are faster because they actually only write the final results.
For example, in the index rebuild case, the operations doing the SQL are
a. read table, get column values from table
b. sort values
c. if allocated pga/sort_area is insufficient, overflow to disk
d. run final sort pass, if necessary
e. write sorted results to the index segment
(recursive SQLs to allocate extents, update the data dictionary for the index definition also have to be applied, each of these also having to read the existing extent maps and data dictionary before updating them).
However, when you run media recovery
1. Oracle does not have to read the table
2. There is no sort operation
3. Writes to temp are avoided (as Temp operations are nologging and there is nothing in the redo to "replay" against the tempfiles)
4. The index blocks are "updated" directly

Media Recovery

I am running Oracle 10g on windows 2003 R2.
1) My UNDO TBS require media recovery, but the data file is in place for the mentioned location.
Error encountered ORA - 01113 - needs media recovery.
How can i do media recovery.
2) My PROD1 TBS was full and i wanted to resize the datafile. i got error on the client admin console and connection was lost.
When i try to connect again to the instance i get ORA- 12638 - credential fail error.
Am not able to connect to the instance from client admin console, but i am already connect thru SQL Plus on the DB Server.
Please adivse how can i resolve this.
Regards

I get following error when i try to recover undo tbs
datafile.
SQL> recover datafile
'e:\oracle\oradata\ptmn\undotbs.dbf';
ORA-00603: ORACLE server session terminated by fatal
errorCheck your alert.log see if there any additional errors.
Check if the datafile is still online,
select * from dba_data_files
where file_id=2Do you have any active transaction in the database ?
select * from v$transactionIf there's no active undo segment, it's might be easier just create a new undo tablespace, change your default undo tablespace to new one and offline drop the old one.

Cancel media recovery
