ORA-01123: cannot start online backup; media recovery not enabled

the Oracle doc says:
Action: Enable media recovery and retry this operation.
how helpful it is!
Could someone advise me on what is exactly the command
for "enable media recovery"?
Thanks.

but when I modified the init.ora file and re-start the
db, I still have "NO archive mode", when I tried to
set it to archive mode I got an error:

ORA-19806: cannot make duplex backups in recovery area

Hi all,
I multiplex my archived log files in 2 places and I ran a backup job via the Enterprise Manager, below is the code generated:
$rman_script="backup incremental level 0 cumulative device type disk tag 'Weekly_Full_Backup' database;
backup device type disk tag 'Weekly_Full_Archives' archivelog all not backed up delete all input;
allocate channel for maintenance type disk;
delete noprompt obsolete device type disk;
release channel;
&br_save_agent_env();
&br_prebackup($l_db_connect_string, $l_is_cold_backup, $l_use_rcvcat, $l_db_10_or_higher, $l_backup_strategy, "TRUE");
my $result = &br_backup();
exit($result);
I actually have the backup but at the same time have this error:
ORA-19806: cannot make duplex backups in recovery area
And it was supposed to delete all the Archived logs but they were not deleted.
Can someone help please?
Thanks in good anticipation.
Creems

It is not possible to duplex backup sets to the flash recovery area.

Media recovery not enabled

I am running/testing just about every XDB feature there is in Oracle XE and I am running into a problem. I am using copyevolve and I am getting an error that I also get in the Enterprise version. That error is not relevant to this post. But in XE it is followed by ORA-30944 Error during rollback for XML schema '<schema_url>' table "<owner_name>.<table_name>" column '<column_name>'. I checked my logs and they have an error stating:
Media recovery not enabled or manual archival only 0x10000
How can I enable this feature? Can someone direct me to where I could find more information on this subject?
Thanks

Here is the exact error message:
ORA-30944: Error during rollback for XML schema 'group.xsd' table "XMLTEST"."GROUP_S" column ""
ORA-02304: invalid object identifier literal
ORA-30942: XML Schema Evolution error for schema 'idenity-mapping.xsd' table "XMLTEST"."identity-mapping2747_TAB" column ''
ORA-00922: missing or invalid option
ORA-06512: at "XDB.DBMS"XMLSCHEMA_INT", line 113
ORA-06512: at "XDB.DBMS_XMLSCHEMA", line 210
ORA-06512: at line 226
I get the ORA-30942 in Enterprise oracle but I do not get the rollback error. I thought that the media recovery message may have been related to the rollback failure because I associated recovery and rollback (Which may be a poor assumption).

Ora-01113: USERS01.dbf need's media recovery when starting database

Bear with me if this seems a stupid question. (I'm a developer and just starting to catch up the DBA job).
Our database server is down and when we tried to bring it back using DBA studio (logon as SYS), we got the following error: ora-01113: USERS01.dbf need's media recovery.
From the documentation I know I can do a media recovery on the datafile. But with the database not being open, how am I getting access to SQL plus and perform this task? I tried to log on using the SYS credential and I could not log on. Please help. Thanks very much. Changsong

Get connection from SQL*Plus at the command line to carry out that so:
export ORACLE_SID<database_sid>
sqlplus /nolog
conn / as sysdba
recover ....

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,

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.
Ruchit.

Good One - "ORA-00308: cannot open archived log", No Recovery Going On

Folks,

This seems to happen after a core dump (memory leak?). No recovery is going on and the database functions normally afterwards.
Why would the database try to access old log filles when not recovering?
Thanks,

Cannot do online backup of 2012 VM within 2012 R2

Hi, I have several Windows 2012 VM's running on a 2012 R2 host. None of these VM's can do an online backup. They both have a SCSI controller installed, and all the HyperV integration services installed. For a 2008 R2 HyperV host, the
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SystemRestore\ScopedSnapshots registry entry needed to be added.
Does this also need to be added when 2012 R2 is the host?

Hi,
Unfortunately, the available information is not enough have a clear view of the occurred behavior. For narrow down the reason, could you provide more information about your
issue. For example, the exact text of any error messages that you received that are associated with this problem?
when this problem occurs the system log record information, screenshots is the best information.
You can refer the following similar thread, if your same with that one you can try to fix it first.

Satellite L500D-13P backup media is not Win 7 64BIT version!

As I read in many posts here, an example:
http://forums.computers.toshiba-europe.com/forums/thread.jspa?threadID=54797
and
http://forums.computers.toshiba-europe.com/forums/thread.jspa?messageID=202946&#202946
and
http://forums.computers.toshiba-europe.com/forums/thread.jspa?messageID=209400&#209400
and so on... The story was I received my laptop with no OS, so I used the 32Bit recovery disk included, now I would use the full 4GB ram and I wanted the 64bit recovery disk, so I ordered the backup media from the site mentioned on all posts here, and for 34,90 EUR (pretty expensive) they sent me the backup media, but is a 32Bit version... for 35 I think at least they would send me both versions not only the 32Bit (that I already have...) any suggestion?
Laptop Satellite L500D-13P

When I ordered:
- No way to choose any version
- No way to mention any extra detail
As the laptop is sold with Win7 64Bit and as I read on many posts here I was lead to believe they send 64Bit version or at least they will send both for that high price.
There's no phone/fax number or mail address in the package... only an address in Germany I woldn't print and send a letter there and hope someone will answer me, we are on digital era paper should be left for old pepole and lawyers, for 35 there should be a better servic, Microsoft has a better and cheaper support for backup media.

Online Backup Database in Linux

I try to use command "alter tablespace system begin backup ; " to back the datafile
but it show me the message "cannot start online backup; media recovery not enabled".
What should I do for that.
thanks

Sounds to me like you are not in Archivelog mode. You can not do HOT backups if you haven't put that database in this mode. I believe you must be in MOUNT state to do this. You will also want to add some lines in your init.ora so that it knows where to write the archive logs and it starts up the process at startup.

No Online backups due to datafiles offline than I canu0092t recover. How...?

Hi gurus!!!
I got into a problem with some datafiles.
We have MySAP in a BD oracle 9.2.0.6
I used Oracle Entreprise Manager Console to generate two datafiles in the tablespace PSAPPRDUSR,
but I generated them in another tablesapce (PSAPPRD) with a name of file,
size and location very different from those that there uses the tablespace PSAPPRD.
So... I put them offline later to erase them later!!!
The datafiles contains no data.
Later, in the night backup:
 BR0334W Status of database file /oracle/PRD/sapdata4/prdusr_2/prdusr.data2 is RECOVER
 BR0334W Status of database file /oracle/PRD/sapdata4/prdusr_2/prdusr.data2a is RECOVER
 BR0301E SQL error -1128 at location BrTspAlter-3
 ORA-01128: cannot start online backup - file 31 is offline
 ORA-01110: data file 31: '/oracle/PRD/sapdata4/prdusr_2/prdusr.data2'
 BR0280I BRBACKUP time stamp: 2007-04-20 03.01.21
 BR0316E 'Alter tablespace PSAPPRD begin backup' failed
 BR0056I End of database backup: bdvbtndh.ant 2007-04-20 03.01.21

And now... I neither can erase them nor can put online again.
To erase them I used:
SQL> ALTER DATABASE DATAFILE '/oracle/PRD/sapdata4/prdusr_2/prdusr.data2' OFFLINE DROP;
Database altered.
SQL> commit;
But they continue there, do not resign.
To put them online:

But we have continued working and I don't want to lose any data.
HEEEELP!!!!
What I can do to recover the datafiles and to continue with my daily Online backups?
The BD is in production and I do not have long time to fix it, only a few hours on Saturdays night.

Hi,
alter database datafile offline drop;
This command is not meant to drop a datafile. It is meant to offline the datafile with the intention of dropping the tablespace.
For a tablespace comprising multiple datafiles you can only drop a datafile by dropping the entire tablespace, this will work even you have one datafile.
If you have 10gr2, it's finally possible to drop a datafile as long as
it's not the only datafile within the tablespace, and
the tablespace is only and in read-write status.
So since you are on 9i your situation in summary:
If you have more than one datafile in the tablespace and you wish to keep the objects that reside in the other datafile(s) which are part of this tablespace, then you must export all the objects inside the tablespace.
1. Gather information on the current datafiles within the tablespace by running some query to remember the t/s, segment, and datafile info.
2. Export all the objects that you wish to keep.
3. Once the export is done, issue the DROP TABLESPACE <tablespace name> INCLUDING CONTENTS.
4. Delete the datafiles belonging to this tablespace using the operating system.
5. Recreate the tablespace with the datafile(s) desired, then import the objects into that tablespace.
Hope this helps and good luck,
George

ORA-01195: online backup of file 65 needs more recovery to be consistent

Hi,
I was doing a clone by taking the hot backup from prod to dev. The backup was good. And then I created the control file, Then I passed the command
recover database until cancel using backup controlfile;
It asked for the archived logs files. I supplied them until current time.
Then I canceled.
That's when I got this error
ORA-01547: warning: RECOVER succeeded but OPEN RESETLOGS would get error below
ORA-01195: online backup of file 65 needs more recovery to be consistent
ORA-01110: data file 65: '/d10/oradata/dwdev/kt01.dbf'
ORA-01112: media recovery not started
What am I doing wrong? I have not yet passed the command "Alter database open resetlogs"
Should I do more logswitches in prod and pass those files to dev ? Or should I just put the kt tablespace in backup mode and copy the data files?

Which set of archivelogs did you copy over to apply ? All the archivelogs from the first ALTER TABLESPACE ... BEGIN BACKUP to the archivelogs subsequent to the last ALTER TABLESPACE ... END BACKUP ?
In the cloned datadabase, what messages do you see in the alert.log on having issued the RECOVER DATABASE command ? Does it complain about the datafiles being fuzzy ? Which archivelogs does it show as having been applied ?
Can you check the log sequence numbers for the duration of the Backup PLUS ArchiveLogs subsequent to the Backup ?

ORA-01124: cannot recover data file 1 - file is in use or recovery

I am trying to recover standby database, but it is giving the below error.
ORA-00283: recovery session canceled due to errors
ORA-01124: cannot recover data file 1 - file is in use or recovery, recovery is already stated
ORA-01110: data file 1: 'I:\ORACLE\QAS\SAPDATA1\SYSTEM_1\SYSTEM.DATA1'
when i checked in the alert log the recovery is not started. and later i hae given "alter database recover cancel' and the command end up with the below line
"media recovery not started".
it seems that the recovery has stuck in between.
please advise me how to kill the recovery session that's stuck. because i dont want to bounce the standby database.
thanks in advance.

Without dataguard and MRP, you are running a scripted standby.
In a scripted standby, a RECOVER DATABASE session would have an UNTIL clause (most likely UNTIL SEQUENCE). At the end of the recovery to that point (SEQUENCE#), it exits and shuts down the database.
Also, the scripting is such that when one RECOVER session is active, another session is not allowed to start. It may loop in wait state or exit and retry at the next scheduled interval.
Apparently your standby scripting is not robust enough to prevent another RECOVER session from starting off even as the first is active (and/or it doesn't have a proper UNTIL clause and stop, exit, shutdown actions)
What you have is a custom implementation of a standby database. Without complete details of the script, the "locking" between sessions (to prevent a second RECOVER from starting when one is already running) etc .... we really cannot do much to help you.
Your scripts should be maintaing status information . It should be possible for you to discover the "other" sqlplus session that has issued a RECOVER DATABASE but not yet exited (e.g. ... how about a simple "ps -ef |grep sql" and "ps -ef | grep ora" combination ??)
