Rman clone ? duplicate database ? data guard ? standby database?

hey there !!
What is the difference between Rman clone , duplicate database , data Guard , standby db?
1 more thing , standby database and duplicate database are same??

RMAN Clone : you take backup of a database on one server ,then take it to other server ,again use RMAN to restore the database,A lot manual intervention is needed in this method
RMAN DUPLICATE: same as above just that manual intervention is less. With 11gR2 there active database duplication in which you can clone your test database directly from production database without taking and then transferring the backup to test server.
Standby Database :they are of two types Physical and logical.The setup is done using RMAN with any of the above methods.Standby is the in-sync (can have some delay) version of primary database either block by block which is physical standby configuration or SQL statment wise which is logical standby.
Data Guard:This is also a standby configuration.Here the failover and switchover are automated with the help of DGMGRL utility.In manual standby this same can be done via SQL*PLUS using sql commands

Active data guard standby database

Hello,
we have to choose which technology to use for maintain Oracle backup center synchronized with main center. This backup center should be read only, and data generated in main should be replicated into backup. So I would like to use Active Data Guard, but I have a possible issue with reading in backup center, because reading is not just select, but filling(inserting data) some temporary tables (from client side, and from procedures in database). Will Standby database in backup center allow this if Active Data Guard is used. We would go with Oracle 11gR2.
Also other suggestions on replication technologies (I know there are RAC, ADG, Oracle Streams, Golden Gate), or any document which would help us decide which of these technologies would suit our needs the best.
Thank You.

In 11.1 or later you can use feature "Snapshot Standby Databases" if this write on database is temporary (i.e you will not use the new data) and at backup time you not need use Snapshot Standby Database feature.
A snapshot standby database is a physical standby database that you temporarily convert into an updatable standby database. You can use snapshot standby databases as clones or test databases to validate new functionality and new releases, and when finished you then convert the database back into a physical standby. While running in the snapshot standby database role, it continues to receive and queue redo data so that data protection and the RPO are not sacrificed.
A snapshot standby database has the following characteristics:
* A snapshot standby database cannot be the target of a switchover or failover. A snapshot standby database must first be converted back into a physical standby database before performing a role transition to it.
* A snapshot standby database cannot be the only standby database in a Maximum Protection Data Guard configuration.
Note:
Flashback Database is used to convert a snapshot standby database back into a physical standby database. Any operation that cannot be reversed using Flashback Database technology will prevent a snapshot standby from being converted back to a physical standby.

Also other suggestions on replication technologies (I know there are RAC, ADG, Oracle Streams, Golden Gate), or any document which would help us decide which of these technologies would suit our needs the best.If you need "standby" database opened in read-write all time the best option is to use Golden Gate.

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$LOG_HISTORY LH,
V$DATABASE DB WHERE LH.RESETLOGS_CHANGE#=DB.RESETLOGS_CHANGE# AND LH.RESETLOGS_TIME =

do you know what is problem

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

Error while trying to open physical standby database - (DATA GUARD)

Hi Everyone,
I have problems in opening the database of the physical standby in read- write mode/ read only mode. I have a primary server which is running on 2 node RAC and the standby on a seperate single server being used as DR. I recently got this server and my aim was to isolate the standby server from primary server and perform few test. As it has never been tested even once.
Primary Database spec: (2 Node Rac on ASM)

Data Guard Standby DB Duplicate entries in v$archived_log - apply stopped

Hi
I've got a perplexing problem... I have a number of archive logs that seem to have gotten duplicated (there are no other log files past or prior to this particular point). This duplication however has stopped the apply of the logs to the standby database. (Getting the 'apply' to continue is of paramount importance)
Any suggestions on how to remove the 'duplicate' entries on the standby database would be appreciated.
Here is the output from my query on the v$archived_log view:

Shipping of logs are continuing normally (we had to stop McAfee on the machines -- wrecked havoc with the replicaton -- not sure if the duplication can be attributed to the virus checker too)
Thanks for the attention to this problem...
Kind Regards

Thanks for posting - I've not made any changes to this system. The archive log listing I posted is from my standby database and after it got itself out of whatever not it got itself into in the first place, it applied all the logs... even these duplications have updated to YES (in the applied column). Very strange occurence... have not seen it since this. Hope it's a once off aberation.
since this is no longer a problem... I'll mark this question as answered.
Thanks to all who looked at it.

Data Guard Standby Lost A Drive Or Two

So a data guard standby is somewhat disgruntled because the SAN imploded and the standby lost a couple mount points. It wasn't running ASM so no self-repairing can occur. Since this is the first time I've had a serious issue with a standby and since much of what I do is restricted (RMAN complains because it's a standby and read-only)... I'm just curious if someone could point me towards a comprehensive "what to do when your STANDBY has issues" book, document, or link. They are surprisingly scarce. Most comments online simply say (paraphrased) "scorch the earth, salt the fields, and rebuild fresh."
Thank you

Hello;
Depends what you lost.
1. You can just rebuild.
2. You might be able to use RMAN roll forward.

3. If you are Oracle 11 you can use RMAN active duplicate to rebuild.

A new question on how to Enable Flashback Database on the standby database?

Best Practice document said:
Enable Flashback Database on the standby database to minimize downtime for logical corruptions.
I would like to know where to find document or anybody already had experience for this topic?
Also I would like to know what is the best practice for backup/recovery of the Physcial standby database?
Thanks in advance.

Hello;
Just an opinion but I like the book "Oracle Data Guard 11g Handbook" as both the document and the answers to the second question.
Chapter 12 covers the A to Z of RMAN with Data Guard.
This book sold me on Flashback since Flashback allows a former Primary database to be reinstated after a failover operation with being restored ( provided sufficient flashback logs are available)
My own experience is I tried a failover test without it and trash my test Primary.
I did a simple failover test a few weeks ago, here are my notes.

Data guard standby restart in rocover mode

Hi,
I inherited a data guard database and found that the secondary DB has been out of sync with primary. I perform SCN recovery to the secondary and now they are fine syncing. I figured I had to manually put the standby in recover mode after open in read only mode in the one I worked on which is our qual environment where as it is not like that in the prod. Can anyone advise what I need to do to have this standby in recovery mode even after the DB go down for maintenance and come back on?
Thanks for your input,
fakord

Hi,
If you are using database guard broker then it will automatically starts the apply as it controls the apply. If not probably a shell script to start the standby database followed by this line can help.
alter database recover managed standby database using current logfile disconnect from session;

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.

Implent streams on primary database having one standby database

hi
we have two databases one is primary amd second one is standby database.
i.e.,we implemented dataguard.
Now we are planing to implement stream of primary data to different database not the standby database.
Does any one suggest that streams can be implement along with dataguard.
I f yes please suggest to me how to implement streams in 10g release2.
Regards,
JAY

Hi Jay
I'm facing the same problem.
Did you or anyone else manage to put both working?
My problem is that I cannot get rid of the log_archive_config parameter. He demands me to include the streaming destination database on it. When I putted , he says that's not a dataguard database (off course is not) .... so , I'm in a deadlock trying to configure a dataware house model with streams under dataguard environment
Any help?
Thank you

ALTER DATABASE RECOVER MANAGE STANDBY DATABASE

During the creation of Logical Standby database (NOAA2), after issuing the statement:
"ALTER DATABASE RECOVER MANAGE STANDBY DATABASE"
the following error appears:
FAL[server, ARC1]: Complete FAL noexpedite archive (thread 1 sequence 46 destination NOAA2)
ARC1: Attempting destination LOG_ARCHIVE_DEST_2 network reconnect (3113)
ARC1: Destination LOG_ARCHIVE_DEST_2 network reconnect abandoned
PING[ARC1]: Error 3113 when pinging standby NOAA2.
Can someone please shed any light on the problem.
Thank you.

Perform these steps on Standby and see if it works

Can i convert logical standby database to physical standby database

Dear All,
Can i convert a logical standby database to physical standby database?
If yes, what are the steps to follow?
Thanks
Mahipal

I never needed or tested something like this, but below maybe usefull -
Transient Logical Standby
Users can convert a physical standby to a transient logical standby database to effect a rolling database upgrade, and then revert the standby to its original state as a physical standby database once the upgrade is complete - using the KEEP IDENTITY clause. This benefits physical standby users who wish to execute a rolling database upgrade without investing in redundant storage otherwise needed to create a logical standby database.
http://www.oracle.com/technology/deploy/availability/htdocs/DataGuardOverview.html
But opposite is documented - http://download-west.oracle.com/docs/cd/B19306_01/server.102/b14239/create_ls.htm#BEIGJCAC

How can i migrate oracle database data to DB2 database

Hi
how can i migrate oracle database data to db2 database.
can anyone provide me solution.

BTW why do you want to migrate oracle database data to db2 database? Any specific project requirement like Parallel run with Oracle database (e.g data replication)? Or any other issues - Cost? Manageability? Availability? Business requirements?
Do you need to do a day-to-day data transfer or it is for permanent migration?

ALTER DATABASE RECOVER MANAGED STANDBY DATABASE

Hi,
on 10g R2, how to know if :
ALTER DATABASE RECOVER MANAGED STANDBY DATABASE
DISCONNECT;
is already applied ?
thank you.

thanks to all.
Should I issue the following and others on standby or on primary ?
select process,status from v$managed_standby;
Regards.You need execute that from standby instance.In additionally you can see standby instances alert.log.And if this process is active then if you execute this command again then you will get an error like "Media recover is active".

Rman clone duplicate database from active database

Hi All,
I read document saying that rman can duplicate database from active database (prod) to a remote server, so long as you configure listener and tnsname.
I am working toward it.
I met a problem, which is when i bring up auxiliary database in nomount mode, the listener service of that auxiliary database is in BLOCKED status, and throw out ora-12528 error when I rman auxiliary sys/pass@clonedb. Isn't nomount mode the mode which auxiliary db is supposed to be in?
(ora-12528: TNS:listener: all appropriate instances are blocking new connections)
Thanks,
milic

You may have run into the same problem like I did recently:
The (UR=A) clause in tnsnames.ora is intended to work with a dynamically registered handler so the use of SERVICE_NAME versus SID is preferred.
ORA-12528: TNS listener BLOCKED - trying to duplicate database
Also for further problems:
RMAN 11gR2 duplicate database ORA-17627 ORA-01017 RMAN-03009 ORA-17628

Both databases are running on Oracle10g platform .
Waiting for ur kind reply .. ...

You need to:
- create a SPFILE manually for standby database
- use the RMAN command: DUPLICATE TARGET DATABASE FOR STANDBY
- remove all SPFILE statements from RMAN script.

Rman clone ? duplicate database ? data guard ? standby database?
