Rman duplicate on Active dataguard physical standby

In DR site. i have to clone the database from pshysical standby database and clone db will be normal db not standby. Is it possible to do rman duplicate from active dataguard? will it support the duplicate database from active database or i have to take the rman backup of standby database and duplicate from backup piece. please advise

Active dataguard physical standby

Hi,
Is it possible to create additional tables and do DML operations on them ( these tables will not be present on primary db) in physical standby database created by active data guard.
Regards,
prasad.

Is it possible to create additional tables and do DML operations on them ( these tables will not be present on primary db) in physical standby database created by active data guard.Prasad,
Here Active datagaurd feature is only for READ ONLY or reporting purpose, where you can perform only Select queries which is from 11gRx at the same time recovery also will be active.
If you want to open database in Read & Write , There there would be no consistent with Primary database, These behaves as different databases.
So Either you have to use flashback option after completing your REad & Write options,
Again you will lost all of the data, whatever you performed DML operations. So this is no use again.
You can use this note for that procedure *How To Open Physical Standby For Read Write Testing and Flashback [ID 805438.1]*
But i can say conclusion to make your standby high available your DML operations are not supported, ofcourse supported but its not High availability.
Hope this clears.

SAN based restoration or RMAN restoration for Active Dataguard

Hi ,
We have oracle 11gr2 on aix OS ,I am planning to configure active dataguard for DB size 250 GB.
FOr DB restoration on standby side if i go for SAN based OS block level Relication between primary and standby how to link DB LUn on standby which are mounted with diffrent LUN name on standby DB.
OR RMAN restoartion is only method to go for standby DB restoartion ..
My conncerns is if i go for RMAN than it will take more than 8 hours and it will affect my DB performance ..
Please help me suggest which approch is better ? If it SAN based than how to link LUn to DB file .
Thanks in Advance.

RAC & DataGuard (Physical Standby)

Hello all,
I'm trying to get a high level overview of how RAC & DataGuard would behave in the following configuration. I've written down my understanding of how things would work. Please correct me if I'm wrong.
1) 2 node RAC (Primary Database) with a single instance physical standby.
a) Same standby related init.ora parameters would have to configured on both primary rac nodes.
b) The redo apply service at the standby would merge the redo from the 2 threads from the primary and apply it to the standby to keep it in sync.
c) During switch over only one primary RAC instance should be up besides the standby instance.
d) During switch back again only one primary RAC instance should be up besides the standby instance.
e) During failover ofcourse both primary instances would be down which warrants the fail over.
2) 2 node RAC (Primary) with a 2 node physical standby
This where it gets complex and I'm not really sure how a,b,c,d,e would be in this scenario. Appreciate if you could shed some light on this and list what
a,b,c,d,e would look like in this scenario.
I'm assuming that only one instance in the standby RAC should be up when the standby is in RAC configuration for the redo apply to work.
Also, if there is a white paper that details step by step procedure for setting up the above 2 scenarios, please let me know. So far I was able to find only the MAA white paper but that was not very helpful. If you can prescribe a good book for RAC & DataGuard that would be great too..
Thanks for your help

>
1) 2 node RAC (Primary Database) with a single instance physical standby.
a) Same standby related init.ora parameters would have to configured on both primary rac nodes.Usually rac nodes share their spfile on a shared diskvolume or through ASM. So they have identical DG parameter anyway
b) The redo apply service at the standby would merge the redo from the 2 threads from the primary and apply it to the standby to keep it in sync.Correct
c) During switch over only one primary RAC instance should be up besides the standby instance.
Sounds logical to me
Edit: In fact during normal operation both RAC nodes are up, so during switchover they are both active too
It is the configuration that matters. As soon as the standby is becoming primary, it might be that it talks only to one RAC node for its log-apply files
d) During switch back again only one primary RAC instance should be up besides the standby instance.That single was the only one running in step c.
e) During failover ofcourse both primary instances would be down which warrants the fail over.Correct. Keep in mind that during a failover the RAC config would be deconfigured from the DG setup and has to be added back again as standby.
You might have to take a look at: http://www.oracle.com/technology/deploy/availability/pdf/MAA_WP_10g_RACPrimarySingleInstancePhysicalStandby.pdf

No. RAC primary to RAC Standby would mean both nodes are up on both side. PrimNode1 send its redo logs to StandbyNode1 and the same for PrimNode2 and StandbyNode2

关于Rman Duplicate from active databse 到一个新库中出现的问题

auxiliary: dbacoe 11.2.0.3
发生情景
将旧库home目录Clone到同机另一文件夹并做完所有操作后，欲进行duplicate
在新home目录中
1.新建pfile initdbacoe.ora如下
DB_NAME=dbacoe
DB_FILE_NAME_CONVERT=(/u03/apps/oracle/oradata/hzdbacoe/,/u03/app/oracle/oradata/dbacoe/)
LOG_FILE_NAME_CONVERT=(/u03/apps/oracle/oradata/hzdbacoe/,/u03/app/oracle/oradata/dbacoe/)
2.新建orapw file=orapwdbacoe.ora password=oracle
3.mkdir -p $ORACLE_BASE/oradata/dbacoe并赋好权限
4.根据该pfile起至 nomount阶段instance为dbacoe
5.在该目录的listener.ora中新建一个监听，并将dbacoe服务注册进入该监听，端口为1530
在原库所在环境变量中
修改tnsname.ora 加入dbacoe信息如下：
dbacoe =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = xxxx.xxx.xxx)(PORT = 1530))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = dbacoe)

RMAN>duplicate target database to dbacoe from active database nofilenamecheck;(ps:之前第一次有运行过一次duplicate，未加nofilenamecheck，报错后加上）

找到原因了，还是官方文档看得不仔细
2.At the RMAN prompt, run CONNECT commands for the database instances required for your duplication technique:
◦For active database duplication, you must connect to the source database as TARGET and to the auxiliary instance as AUXILIARY. You must use the same SYSDBA password for both instances and must supply the net service name to connect to the AUXILIARY instance. A recovery catalog connection is optional
唉，把大量时间花在组织提问上了，希望大家引以为戒。有时候，更该去清洗一下思路，重新着手

Got RMAN error when running RMAN backup of archivelogs on physical standby database

Got below error when running RMAN backup of datafiles and archivelogs on physical standby database.
RMAN-06820: WARNING: failed to archive current log at primary database
ORACLE error from target database:
ORA-17629: Cannot connect to the remote database server
ORA-17627: ORA-00942: table or view does not exist
Could anyone help me? Thanks,

Hello;
When you connect RMAN to the source database as TARGET you must specify a password even if RMAN uses operating system authentication.
So the errors ORA-17627 and ORA-00942 appear to be cause and effect.
What version of Oracle? ( 11.2.0.4 according to the tag )
Can you post your backup script?
Best Regards
mseberg
Update
According to :
Database Error Messages 11g Release 2 (11.2) E17766-03
RMAN-06820: WARNING: failed to archive current log at primary database
Cause: An attempt to switch the archived log at the primary database failed.
So I would check my Primary alert log for an issue.

RMAN duplicate from ACTIVE DATABASE

Hi,
I am trying to create a new 11.2.0.1 database by duplicating an existing 11.2.0.1 database using Rman with 'from active database' option.
I have created a password file and listener is configured as well.
The aux database is started in nomount state.
rman
connect target sys/pwd123@SRCDB
connect auxiliary sys/pwd123@AUXDB
duplicate target database to AUXDB
FROM ACTIVE DATABASE;
This fails saying that "ORA-12528: TNS:listener: all appropriate instances are blocking new connections" which is quite normal given that the listener is havig a handle in BLOCKED state for this AUXDB as it is in NOMOUNT state.
Could you please help me on how to proceed?
One option can be to create the controlfile manually and mount the instance before doing the duplicate. I hope Rman can continue from there.
Another option is to go for backup based duplicate.
Is there any other way to go?
Regards,
Aravind

Provide static registration on AUXILIARY side for your auxiliary instance and try again.For example change listener.ora file as
SID_LIST_LISTENER =
(SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME = AUXDB)
      (ORACLE_HOME = <your oracle home>)
      (SID_NAME = AUXDB)
LISTENER =
(DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = <auxiliary host/ip>)(PORT = 1521))
)And restart listener on auxiliary host then try again

Dataguard physical standby archive log question

Hi all,
I will try to keep this simple..
I have a 4 node RAC primary shipping logs to a 2 node physical standby.
On the primary when I run 'alter system archive log current' on an instance I only see 1 log being applied on the standby, that is by querying v$archived_log.
If I run the following on the standby:
select thread#,sequence#,substr(name,43,70)"NAME",registrar,applied,status,first_time from v$archived_log where first_time
in
(select max(first_time) from v$archived_log group by thread#)
order by thread#
I get:
THREAD# SEQUENCE# NAME REGISTR APPLIED S FIRST_TIME
1 602 thread_1_seq_602.2603.721918617 RFS YES A 17-jun-2010 12:56:58

4 319 thread_4_seq_319.2606.721918625 RFS NO A 17-jun-2010 12:57:00
Why do we only see the max(sequence#) having been applied and not all of them?
This is the same no matter how many times I archive the current log files on any of the instances on the primary and also the standby does not have any gaps.
Hope this is clear..
any ideas?

as a reminder we have a 4 node RAC system shipping logs to a 2 node RAC standby. There are no gaps but only one log is ever registered as being applied.
Why is that? Why arnt all logs registered as being applied?

Large import on dataguard (Physical Standby 11.2 )

Hi experts,
I have to import a great database (50 Gigabytes) (with impdp) which should be configured with a standby database.
My Question:
Should I make the import before or after the configuration of the standby database?Thanks & regards

Do the IMPORT first.
If you don't you risk messing up the FRA on both the Primary and the Standby side. The redo will stop applying the second the FRA hits the limit on the Standby or worse yet a day or two later when you think you are in the clear. Even if for some reason you don't use FRA shipping all that redo isn't a good idea on a new Data Guard system. You might have another issue and you just compound it by doing an import of this size. On most systems you would be adding an additional 500 plus redo logs to the mix.
Also you can duplicate the Standby database using RMAN after the import very easily.
I probably wait a least a few days after I imported on the future Primary before I built the Standby.
I have a solid duplicate document and will share if you decided to go that route.

10g dataguard - physical standby database

Hi Guys,
DB1 <Primary> - Production
DB2 <Physial Standby> - DR
I will need to startup my DB2 in DR segment for testing.
If i perform the below, will it affect my Production DB? I need it to be up and running as well.
DR:
recover managed standby database cancel;
shutdown immediate;
startup nomount;
alter database mount standby database;
recover standby database until cancel;
alter database activate standby database;
thanks

Hi,
In 10g version, you can open database database with READ ONLY mode. In that case standby database
recieve primary generated changes but not apply .
I see you steps you using ALTER DATABASE ACTIVATE STANDBY DATABASE statement for activating database
Activate the standby database using the SQL ALTER DATABASE ACTIVATE STANDBY DATABASE statement. This converts the standby database to a primary database, creates a new reset logs branch, and opens the database.*
If you are not need convert standby database to primary database then , you must use only
ALTER DATABASE OPEN READ ONLY;
