Hello All,
In my physical stdby database alert log I could see the below message, I'm not sure what id Media Recovery Log and why it is dumping ORACLE_HOME Directory..?
Could any one please help on this..? I need to house keep ORACLE_HOME directory.

Hello;
The alert log is providing you with information. If you want more run this query :
select process,status,client_process,sequence# from v$managed_standby;You should see processes like ARCH, RFS and MRP0.
MRP will tell you if its applying log(s), waiting for a log, or if it thinks there's a gap.

Related to recovery in Physical standby database in RAC

In Physical Standby database all instance involved in recovery processes or any one instance will be their in in recovery mode
If is like this another instance will be for high availabily can any one in forum explain me it will be help full

With your Primary database being RAC, the Physical Standby does not have to be RAC, although, obviously it would be preferred to have scalability as required at a DR site.
Whether your Standby is RAC or non-RAC, the automatic Recovery that is done at the Standby is done by one instance only. It would be applying the ArchiveLogs from all the threads (i.e. instances) of the Primary.
Database Recovery is always done by a single instance.

Physical standby database standby redo log problem

Hello
We have a physical standby database , I've created some standby redo log files but my problem is that they aren't used,
their status in v$stanby_log view is UNASSIGNED
and I see this message (ORA-16086: standby database does not contain available standby log files) in primary database alert_log file
while when I run "alter system switch logfile" in the primary database it transfer redo logs to the physsical standby database
and archive log file will be created in standby database
I've even recreated the standby redo log files and I added new ones to them but the problem wasn't solved
Do you know what is problem ?

No space in recovery area for active standby redo logs
The primary database is operating in MAXIMUM PROTECTION
or MAXIMUM AVAILABILITY mode, and the standby database
does not contain adequate disk space in the recovery area
to safely archive the contents of the standby redo logfiles.
ORA-16086: standby database does not contain available standby log files
when I saw this line "No space in recovery area for active standby redo logs" I thought that STANDBY_ARCHIVE_DEST parameter points where that there is no enough space , but when I consider I found out that points a directory on disk a "sda" that has enough space , I don't know what that means

Apply missing log on physical standby database

How to apply the missing log on physical standby database?
I already registered the missing log and started the recovery process.
Still...having log on standby that has status ..not applied.
SQL> SELECT SEQUENCE#,APPLIED FROM V$ARCHIVED_LOG ORDER BY SEQUENCE#;
SEQUENCE# APP
16018 YES
16019 YES
16020 NO ---------------------> Not applied.
16021 YES
Thanks

Not much experience doing this, but according to the 9i doc (http://download-east.oracle.com/docs/cd/B10501_01/server.920/a96653/log_apply.htm#1017352), all you need is properly-configured FAL_CLIENT and FAL_SERVER initialization parameters, and things should take care of themselves automatically. Let us know if that doesn't work for you, we might be able to think of something else.

What are the differences of creating a physical standby database with ASM?

I want to create a physical standby database for my 10g(10.2.0.1) database. But it is using ASM. Is it possible to create a standby database for a database using ASM?
What are the differences of creating a physical standby database with ASM?

tell us what your research shows and we'll try to
validate it. I am simulating Oracle ASM on a PC and I want to try
DataGuard on it now. So I am trying to create DataGuard
on an ASM system. The purpose is only learning and test.That's telling us how you are researching, not what you have observed.
Your research could have included looking at the documetation, and you might have found http://download.oracle.com/docs/cd/B19306_01/server.102/b14239/scenarios.htm#sthref1642
which discusses exactly what you are looking for.

Problem in recover physical standby database(Data Guard) by rman

Hello to all
I have created a physical standby database ,I want make backup of it by rman and when I lose it's datafile I can restore it ,making backup and restore is fine but in recovery I encounter some problem
scenarios is follow
1- In rman I create a backup of standby database by this command:
backup database plus archivelog delete all input;
2- I run this comman in rman for recover standby database
run{
2> set until scn 1392701;
3> restore database;
4> recover database;
5> }
(1392701 is extracted from this query "SELECT MAX(NEXT_CHANGE#)+1 UNTIL_SCN FROM V$LOG_HISTORY LH,

hi
I myself have found the solution , when I recover the standby database
it do recovery but at the end of recovery it raise the error(RMAN-06054: media recovery requesting unknown log: thread 1
seq 118 lowscn 1392700) but if I begain redo apply before open the database
and I wait till all redo apply process start and communication between the
standby database and the primary database start, then I can
open the standby database and no error will raise
but if befor restarting redo apply I open the database I'll recieve the
ORA-01152: file 1 was not restored from a sufficiently old backup
ORA-01110: data file 1: '/u01/app/oracle/oradata/sari/system01.dbf' error
thanks

Corrupting the block to continue recovery in physical standby

Hi,
Just like to inquire how I will be able to corrupt the block to be able to continue the recovery in the physical standby.
DB Version: 11.1.0.7
Database Type: Data Warehouse
The setup we have is primary database and standby database, we are not using dataguard, and our standby setup is another physical copy of production which act as standby and being sync using script that being run from time to time to apply the archive log came from production (its not configured to sync using ARCH or LGWR and its corresponding configurations).
Then, the standby database is not sync due to errors encountered while trying to apply the archive log, error is below:
Fri Feb 11 05:50:59 2011

Based on the error log it seems we are hitting some bug from metalink (document id 460169.1 and 882851.1)
my question is, the datafile # is given, block# is known too and the data object is also identified. I just verified that object is not that important, is there a way to set the block# to corrupted to be able the recovery to continue? Then I will just drop the table from production so that will also happen in standby, and the block corrupted will be gone too. Is this feasible?
If its not, can you suggest what's next I can do so the the physical standby will be able to sync again to prod aside from rebuilding the standby?
Please take note that I also tried to dbv the file to confirm if there is marked as corrupted and the result for that datafile is also good:
dbv file=/u02/oradata/<sid>/<datafile>_19.dbf logfile=dbv_file_36.log blocksize=16384

damorgan, i understand the opinion.
just new with the organization and just inherit a data warehouse database without rman backup. I am still setting up the rman backup thats why i can't use rman to resolve the issue, the only i have is physical standby and its not a standby that automatically sync using dataguard or standard standby setup, i am just checking solution that is applicable in the current situation

Firstly you can use "*select sequence#,first_time,next_time from v$archived_log order by sequence#;"* command in mount stage itself.No need to open the standby database in ready only mode.
No rows selected in mount stage also.
The V$ARCHIVED_LOG fixed view on the physical standby database shows all the archived redo log files received from the primary database.

no rows selected.
and No archived logs received from primary database to physical standby . i think here i wrongly configure parameter file.
sql> RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION; -- > start Redo Apply
When you do log switch on the primary are the archive logs getting transferred to the standby database???Is there some error in the alert log file in the primary database.
No..

HI CKPT,
Thanks for the reply. All the Archives from primary are transferred to the standby by RFS. Also i tried to register the log files manually even but it says already registered. They are no errors in the primary instance alert log file. Please find the log

Physical Standby database Vs. Logical Standby database

I have few questions regarding capability of Logical Standby Database against Physical Standby database.
1. How efficient is Logical Standby database in terms of Physical Standby Database?? How both differ from each other and can I use Logical Standby Database for disaster Recovery?? Can It be use for recovering the failed Primary Instance?? If yes how efficient and reliable it is??
2. What are the known bugs and roadblocks for logical standby database on Oracle 10.2.0.1 on Soalris X86-64?
3.As logical standby database not going to replicate each and every schema of Primary database?? how is the change management effects to the logical standby from primary?? I mean there are some parameters and job that we create on primary how can it be transferred over to the logical standby??

1. How efficient is Logical Standby database in terms
of Physical Standby Database?? How both differ from
each other and can I use Logical Standby Database for
disaster Recovery?? Can It be use for recovering the
failed Primary Instance?? If yes how efficient and
reliable it is??I'm not sure what sort of "efficiency" you're talking about here...
Physical standby is just the old, tried and true application of archived logs to recover a database. Very solid, very old school.
Logical standby, on the other hand, is parsing the redo log, extracting logical change records, and applying them to the standby database. This obviously takes a bit more processing effort, it's newer technology, it doesn't have quite the level of support that physical standby does (i.e. certain data types are excluded), etc. You certainly can use it for failover, but it isn't quite as robust as a physical standby. Of course, this is getting better and better all the time and is definitely a focus of Oracle's development efforts.
On the other hand, logical standby systems can do things other than act as a warm standby. They can be open serving reports, for example. You can create additional structures (i.e. new materialized views) to support reporting. A physical standby is pretty much always going to be in managed recovery mode, so it cannot be queried.
2. What are the known bugs and roadblocks for logical
standby database on Oracle 10.2.0.1 on Soalris
X86-64?a) You'll want to do a Metalink search
b) If you're talking about a high-availability solution, why are you looking at a base release of the database? Why wouldn't you apply the latest patchset?
3.As logical standby database not going to replicate
each and every schema of Primary database?? how is
the change management effects to the logical standby
from primary?? I mean there are some parameters and
job that we create on primary how can it be
transferred over to the logical standby??I'm not sure I understand... Changes made to the primary generate redo. Oracle parses that redo, generates a LCR, and sends that to the standby database where that change record gets applied.

Data Guard - Steps to install Physical standby database in an RHEL 5.6 x86

HI Team,
I need to install Physical standby database in a OS installed from factory with most basic packages. Please find the info in detail
Standby Server :
Database Version : 10g Release 2
Operating System : Red Hat Enterprise Linux Server release 5.6 (Tikanga) , RHEL 5.6 x86_64
swartis.dc$ free -m
total used free shared buffers cached
Mem: 34158 33847 311 0 558 28367
-/+ buffers/cache: 4921 29237
Swap: 10001 63 9937
- Things i need to validate in the PROD server. Eg : Are the prod db version & standby db version should be the same, Do the OS need to be same ............ETC
- Basic Linux rpm required for standby server & any other pre-requisites required at standby server
- Verify connectivity speed btw servers to decide log file size
- Please give me more detailed steps , where i need to start the steps in installation of Physical standby database.
Thanks in advance.

Hello again;
Sorry for the Delay.
To this question "Do i need to install 10.2.0.2.0 ORACLE_HOME & on top of it apply 10.2.0.3.0 patchset.?"
Yes.
All my Oracle 10 installs started with 10.2.0.1 and then I patched up from there. If I remember correctly 10.2.0.1 may bark on Red Hat 5.
You can work around this by reviewing this file :
/etc/redhat-releaseSave whatever is in there somewhere and replace it with :
redhat-3After the install put back what was there and get rid of the "redhat-3".
I extra RPM's I used were :
rpm -ivh kernel-headers-2.6.18-164.el5.x86_64.rpm

Currently I have 3 servers running both Oracle 10 and 11 ( In different homes ) using this OS.
I have used Oracle 11 document with Oracle 10 also : ( Better once you are setup and a great standby recovery document )

Physical standby database Version 11g Creation over grid control 10g

We are useing oracale 11g enterprise edition and want to create a physical standby database on another machine:
On primary host we've installed "standard database" and turned on archive log mode over em.
On the standby host we've installed only oracle without a database and without a listener.
On a third machine we've installed grid control and registered the primary and standby hosts. Using EM with Data Grid I'm attempting to create a Physical Standby on standby host. Everything is working except for the last part as noted here:

What is to do?
What mean's in this case:
"ORA-01152 file string was not restored from a sufficiently old backup
Cause: An incomplete recovery session was started, but an insufficient number of redo logs were applied to make the database consistent. This file is still in the future of the last redo log applied. The most likely cause of this message is forgetting to restore the file from backup before doing incomplete recovery.
Action: Apply additional redo log files until the database is consistent or restore the datafiles from an older backup and repeat recovery."

Thanks for your immediate reply,
but there's a problem: We don't create the standby database manually. The creation is done by data guard over grid control. And the "automatic" creation stopps at this point.
Unfortunatly we don't know, wich steps of a manuall standby database creation are done and wich steps are not done at this point.
The oracle documentation (for release 11g) to create a manuall standby database is "B28294-02". But there's no step 5 "alter database recover managed standby database disconnect from session". Do you mean step 4 of chapter 3.2.6?
Is there no way, to create a standby database automatically over grid control? Or do we have to do something else before creating the physical standby database? Perhaps we have to create a full backup after switching to archive log mode?

Physical standby database fail-over

Hi,
I am working on Oracle 10.2.0.3 on Solaris SPARC 64-bit.
I have a Dataguard configuration with a single Physical standby database that uses real time application. We had a major application upgrade yesterday and before the start of upgrade, we cancelled the media recovery and disabled the log_archive_dest_n so that it doesn't ship the archive logs to standby site. We left the dataguard configuration in this mode incase of a rollback.
Primary:
alter system set log_archive_dest_state_2='DEFER';
alter system switch logfile;
Standby:
alter database recover managed standby database cancel;Due to application upgrade induced problems we had to failover to the physical standby, which was not in sync with primary from yesterday. I used the following method to fail-over since i do not want to apply any redo from yesterday.
Standby:
alter database activate physical standby database;
alter database open;
shutdown immediate;
startupSo, after this step, the database was a stand alone database, which doesn't have any standby databases yet (but it still has log_archive_config parameter set and log_archive_dest_n parameters set but i have 'DEFER' the log_archive_dest_n pointing to the old primary). I have even changed the "archive log deletion policy to NONE"
RMAN> configure archivelog deletion policy to none;After the fail-over was completed, the log sequence started from Sequence 1. We cleared the FRA to make space for the new archive logs and started off a FULL database backup (backup incremental level 0 database plus archivelog delete input). The backup succeded but we got these alerts in the backup log that RMAN cannot delete the archivelogs.
RMAN-08137: WARNING: archive log not deleted as it is still neededMy question here is
1) Even though i have disabled the log_archive_dest_n parameters, why is RMAN not able to delete the archivelogs after backup when there is no standby database for this failed-over database?
2) Are all the old backups marked unusable after a fail-over is performed?
FYI... flashback database was not used in this case as it did not server our purpose.
Any information or documentation links would be greatly appreciated.
Thanks,
Harris.

Thanks for the reply.
The FINISH FORCE works in some cases but if there is an archive gap (though it didn't report in our case), it might not work some times (DOCID: 846087.1). So, we followed the Switch-over & Fail-Over best practices where it mentioned about this "ACTIVE PHYSICAL STANDBY" for a fail-over if you intend not to apply any archivelogs. The process we followed is the Right one.
Anyhow, we got the issue resolved. Below is the resolution path.
1) Even though if you DEFER the LOG_ARCHIVE_DEST_STATE_N parameter's on the primary, there are some situations where the Primary database in a dataguard configuration where it will not delete the archive logs due to some SCN issues. This issue may or may not arise in all fail-over scenarios. If it does, then do the following checks
Follow DOCID: 803635.1, which talks about a PLSQL procedure to check for problematic SCN's in a dataguard configuration even though the physical standby databases are no available (i.e., if the dataguard parameters are set, log_archive_config, log_archive_dest_n='SERVICE=..." still set and even though corresponding LOG_ARCHIVE_DEST_STATE_N parameters are DEFERRED).
If this procedure returns any rows, then the primary database is not able to delete the archivelogs because it is still thinking there is a standby database and trying to save the archive logs because of the SCN conflict.
So, the best thing to do is, remove the DG related parameters from the spfile (log_archive_config, log_archive_dest_n parameters).
After i made these changes, i ran a test backup using "backup archivelog all delete input", the archive logs got deleted after backup without any issues.
Thanks,
Harris.

Data Guard - MRP stuck issues on a physical standby database

Hi,
Oracle 11.2.0.3 DG running. When i do a switchover the physical standby database has error with following error
ARC0: LGWR is actively archiving destination LOG_ARCHIVE_DEST_2
ARCH: Archival stopped, error occurred. Will continue retrying
ORACLE Instance <primaryDB> - Archival Error
On standby DB
SQL>select process, thread#, sequence#, status from v$managed_standby where process='MRP0';
PROCESS THREAD# SEQUENCE# STATUS
MRP0 1 548 APPLYING_LOG
So according to Oracle support link i executed following
SQL>recover managed standby database cancel;
SQL>recover automatic standby database;
The above seems to resolve the issue. What is causing is this?

Hello again;
Those both look perfect. I combed through my notes and found nothing like this for your version.
Yes, I would open an SR since it appears you have done everything correct.
ORA-600 [3020] "Stuck Recovery" [ID 30866.1]
The "Known Bugs" section of the above has a few 11.2.0.3 entries.
Generally the MRP gets stuck because data Guard thinks there's a GAP, you run out of room in the FRA on the Standby, or redo logs are too small and the system is switching very fast.
Best Regards

Later
Never asked you but this "log_archive_max_processes" can be set as high as 30.

h2. Still later
Found this which is closer :
Bug 13553883 - Archiver stuck but no ORA-19xxx error in alert log (messages need changing) [ID 13553883.8]

What is Media Recovery Log ..? Physical Standby Database
