Create multiple standby databases of primary database

Hi,
I have to create 2 standby databases of a single primary database,
where can i get the stpe for the same?
Thanks

What about FAL_CLIENT parameters in primary?
how to set the values of the above parameter in priamry for second standby database.?
Thanks,In your case do need setting FAL_CLIENT/SERVER in primary database,set these parameter correctly in your standby database.Refer below note

Can Grid Control 10gR2 create a standby database when primary db uses ASM?

Does anyone know if Grid Control 10gR2 will be able to create a standby database when the primary database uses ASM for data files, redo log files, and archive log files but the standby database will use mounted disks? If it can, would it matter that the primary db will be a RAC cluster and the standby will be a single instance db?

I appreciate your reply and hope you are correct. Have you had a look at the 10gR2 Grid Control to confirm this or are you only going on published statements? The reason I ask is because previous versions of Grid Control claimed to support ASM but they would only allow you to work with them AFTER you had created a standby database manually but you couldn't actually use Grid Control to create a standby database from a primary database that had its log files on ASM disks.

Create Multilevel Standby database

HI All,
We have a 10.2.0.2 primary database with a physical standby database.
We would like to create 2 more physical standby databases for the same primary but, we dont want to have the logs shipping from primary database as it is prod.
Is there any way where we could ship the logs from 1st standby to 2nd to 3rd standby.
To me more precise we want to create multilevel standby databases primary--->stby1---->stby2---->stby3.
Thanks,
Anil.

What you describe is referred to as "cascading standby databases"
Let me point you to this thread where I already answered a similar question:
cascade dataguard
Bottom line: You don' need cascading standby - there is as good as no measurable performance impact on the primary with multiple standby databases compared to only one standby.
The only valid reason (it was not performance) for cascading standbys vanished with 11gR2

Dear user13295317,
Here is the error explanation;
Oracle Error :: TNS-12533
TNS:illegal ADDRESS parameters
Cause
An illegal set of protocol adapter parameters was specified.
In some cases, this error is returned when a connection cannot be made to the protocol transport.
Action
Verify that the destination can be reached using the specified protocol.
Check the parameters within the ADDRESS section of TNSNAMES.ORA.
Legal ADDRESS parameter formats may be found in the Oracle operating system specific documentation for your platform.
Protocols that resolve names at the transport layer (such as DECnet object names) are vulnerable to this error if not properly configured or names are misspelled.Hope That Helps.

Problem creating physical Standby database with RMAN

Hi All
I am trying to learn oracle dataguard and as part of the process learning creating standby database.
Platform : Sun-Fire-V250 Sparc, Solaris 10
Database Version - Oracle 11R2
I am creating standby database on same server, so directory structure is different.
Following the instructions on Oracle site I managed to create a functional physical standby database. But I am not able to create standby database using RMAN. These are the steps that I followed-
1.Set up all necessary parameters on primary database as done while creating physical standby database manually, eg setting force logging, creating standby logs etc.
2.Edited parameter file on primary database as done while creating manual pysical standby database creation. Some of the changes done are-
On Primary Database:
*.FAL_CLIENT='orcl11020' #Primary database unique name
*.FAL_SERVER='stdby_11' #Standby database unique name
db_file_name_convert='/<dir>/oradata/stdby_11','/<dir>/oradata/orcl11020'
log_file_name_convert='/<dir>/oradata/stdby_11','/<dir>/oradata/orcl11020','/<dir>/oradata/stdby_11/redo_mem','/<dir>/oradata/orcl11020/redo_mem'
standby_file_management=auto
*.log_archive_config='DG_CONFIG=(orcl11020,stdby_11)'
*.log_archive_dest_1='LOCATION=/<dir>/flash_recovery_area/ORCL11020/archivelog
VALID_FOR=(ALL_LOGFILES,ALL_ROLES) db_unique_name=orcl11020'
*.log_archive_dest_2='SERVICE=stdby_11 LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) db_unique_name=stdby_11'
*.LOG_ARCHIVE_DEST_STATE_1='ENABLE'
*.LOG_ARCHIVE_DEST_STATE_2='ENABLE'
*.LOG_ARCHIVE_FORMAT='%t_%s_%r.arc'
*.LOG_ARCHIVE_MAX_PROCESSES=30
Copied same pfile for standby database and modified following-
*.control_files='/<dir>/oradata/stdby_11/stdby_11.ctl','/<dir>/fra_stdby/stdby_11/stdby_11.ctl'
*.db_name='orcl1102'
*.db_unique_name='stdby_11'
*.FAL_CLIENT='stdby_11'
*.FAL_SERVER='orcl11020'
db_file_name_convert='/<dir>/oradata/orcl11020','/<dir>/oradata/stdby_11'
log_file_name_convert='/<dir>/oradata/orcl11020','/<dir>/oradata/stdby_11','/<dir>/oradata/orcl11020/redo_mem','/<dir>/oradata/stdby_11/redo_mem'
standby_file_management=auto
*.log_archive_dest_1='LOCATION=/<dir>/fra_stdby/STDBY_11/archivelog
VALID_FOR=(ALL_LOGFILES,ALL_ROLES) db_unique_name=stdby_11'
*.log_archive_dest_2='SERVICE=orcl11020 LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE)
db_unique_name=orcl11020'
3. Add relevant information in tnsnames.ora and listener.ora files and then restart listener.
3. Created password file with same credential as primary database.
4.Up-to-date RMAN backup of primary database available.
5.Create standby controlfile with rman
While primary database s open (I tried with primary database in mount mode as well)-
$>rman catalog rman/paswd@rman target /
RMAN> BACKUP CURRENT CONTROLFILE FOR STANDBY;
6. Open a new terminal and startup standby database in nomount mode using parameter file created -
$>ORACLE_SID=stdby_11
$>export ORACLE_SID
$>sqlplus / as sysdba
SQL>STARTUP NOMOUNT pfile='<location/initfilename.ora'
SQL>quit
$> rman AUXILIARY / target sys/passwd@orcl11020 catalog rman/passwd@rman
RMAN>DUPLICATE TARGET DATABASE FOR STANDBY DORECOVER;
RMAN finishes without error but archive logs are not being tranported. Looking at the log, following caught my eye-
Error 1017 received logging on to the standby
Check that the primary and standby are using a password file
and remote_login_passwordfile is set to SHARED or EXCLUSIVE,
and that the SYS password is same in the password files.
returning error ORA-16191
FAL[client, ARC2]: Error 16191 connecting to orcl11020 for fetching gap sequence
Errors in file /<>dir>/diag/rdbms/stdby_11/stdby_11/trace/stdby_11_arc2_24321.trc:
ORA-16191: Primary log shipping client not logged on standby
Errors in file /<dir>/diag/rdbms/stdby_11/stdby_11/trace/stdby_11_arc2_24321.trc:
ORA-16191: Primary log shipping client not logged on standby
So on both primary and standby I confirmed
SQL> show parameter remote_login_passwordfile
NAME TYPE VALUE
remote_login_passwordfile string EXCLUSIVE
To make double sure that password files are same, I shutdown both databases, delete password files and recreated with same credentials.
Password files are called - orapworcl11020 and orapwstdby_11
Can someone guide me where thisngs are going wrong here please.

Not sure if I understood it clearly.
SELECT * FROM V$ARCHIVE_GAP;
returns no rows so there is no gap.
But could you please explain me the result of the previous query. To catch up again, on standby when I check
SELECT SEQUENCE#,APPLIED FROM V$ARCHIVED_LOG
SEQUENCE# APPLIED
75 NO
74 NO
76 NO
77 NO
I understand that though archive files have been copied across but they are not applied yet.
On primary when I give your query -
SELECT name as STANDBY,SEQUENCE#,applied, completion_time
2 FROM v$archived_log
3 where dest_id=2
4 and sequence# BETWEEN 74 and 80;
I get -
STANDBY SEQUENCE# APPLIED COMPLETIO
stdby_11 74 YES 28-JUN-11
stdby_11 75 YES 28-JUN-11
stdby_11 76 YES 29-JUN-11
stdby_11 77 YES 29-JUN-11
stdby_11 78 YES 29-JUN-11
stdby_11 79 YES 29-JUN-11
stdby_11 80 YES 29-JUN-11
stdby_11 75 NO 07-JUL-11
stdby_11 74 NO 07-JUL-11
stdby_11 76 NO 07-JUL-11
stdby_11 77 NO 07-JUL-11
stdby_11 78 NO 07-JUL-11
I have intentionally given
sequence# BETWEEN 74 and 80
because I know in the current incarnaion of the database, max sequence is 78.
So my understanding is, the rows between 28-29 June are from previous incarnation, correct me if I am wrong
Archive files of the current incarnation, since I successfully created standby database are shipped but yet to be applied - am I right?
Then my final question is, when will these archives be applied to standby database?
I am sorry to ask too many questions but I am just trying to understand how it all works.
Thanks for your help again

Creating a Standby Database with the Same Directory Structure

Hello gurus,
I am self-learning the feature Oracle Data Guard, so I am testing it on Oracle 10g R2.
At Oracle documentation there is a section F.4.: Creating a Standby Database with the Same Directory Structure*, that explains how to create a standby database with RMAN but there is something that I don´t understand:
In the standby server, I created a database with the SID equal to production database* with the objetive to have the same directory structure, but when I try to startup nomount the standby database with pfile appear this expected error:
ORA-16187: LOG_ARCHIVE_CONFIG contains duplicate, conflicting or invalid attributes
So my question is: Is possible have the Same Directory Structure on both: Production and StandBy server?
Thanks in advanced.

Uwe and mseberg: thanks for your quick answers
I have a doubt: How can you have the same directory structure if you have differents SIDs?, for example if you follow the OFA suggestions you would must have:
On Production server: */u01/app/oracle/oradata/PRIMARY/system.dbf*
On StandBy server: */u01/app/oracle/oradata/STANDBY/system.dbf*
Or you created the directory structure manually on StandBy server? For example replacing the string STANDBY* to PRIMARY* before create the database using dbca.
Do you understand my doubt? Excuse me for my english.
Thanks.

Can i create a standby database in oracle 10g standared edition ?

what are the steps required for creating a standby database using oracle 10g standard edition. or Any other feature for mirroring database in oracle 10g standared edition

Dear mithun,
Please read the following online documentation;
http://download-west.oracle.com/docs/cd/B19306_01/server.102/b14239/standby.htm
+"+
+2.3.2 Oracle Software Requirements+
+The following list describes Oracle software requirements for using Data Guard:+
+* Oracle Data Guard is available only as a feature of Oracle Database Enterprise Edition. It is not available with Oracle Database Standard Edition. This means the same release of Oracle Database Enterprise Edition must be installed on the primary database and all standby databases in a Data Guard configuration.+
+Note:+
+It is possible to simulate a standby database environment with databases running Oracle Database Standard Edition. You can do this by manually transferring archived redo log files using an operating system copy utility or using custom scripts that periodically send archived redo log files from one database to the other. The consequence is that this configuration does not provide the ease-of-use, manageability, performance, and disaster-recovery capabilities available with Data Guard.+

Hope That Helps.

How to create logical standby database without using Oracle Grid Control

Looking to use DG Broker to create new standby database

Hello,
I'm looking for a good document that can help me to create another standby database on a new server.
I'm running Oracle 11.2 EE on Solaris 10.
We already have one standby database, but now, I want to create another standby database on another server, which ultimately I will make primary and then replace and destroy our current primary/standby databases.
Also, just for the heck of it, I tried to look in our DB Console, and the "Add standby database" is grey'd out.
Is this because I am only using DB Console, and not Grid?
But if that were the case, why would the option even be in DB Console, or perhaps is there a lmiitation to the number of standby databases you can manage with DB Console?

1) Do not confuse Data Guard Broker and Enterprise Manager: DG Broker is mainly a background process (DMON) that can be controlled by EM or with DGMGRL on the command line
2) Only the Grid Control flavor of EM can manage Data Guard Configurations - regardless of the number of Primary or Standby Databases
3) DGMGRL cannot create a new Standby Database - Grid Control can
Kind regards

Multiple standby database about FAL_SERVER and FAL_CLIENT parameter in DG

Hi,
I am little bit confused about FAL_SERVER and FAL_CLIENT parameter in Data Guard.
We are planning to configure multiple standby database in Data Guard environment. Let Assume that, i have production db named as 'PROD' and multiple standby name like standby1,standby2, standby3.
My Environment is:_
DB Version: 11.2.0.1
OS Version: OE5LU6
So in this case how to specify above Net service name in spfile on production server and also on other standby server.
Kindly Suggests me.

AthishFAL_CLIENT is Oracle TNS service of the local system and FAL_SERVER is Oracle TNS service of remote system.
if you have three standby databases of primary , then from primary you must have three values in FAL_SERVER so that archives will be send to the all destinations.
and From the stadnby database, FAL_SERVER should be the oracle TNS service where you receiving the archive log files,
Note:- If you have RAC primary then mention each service differentiated by commas as shown example below.
From standby to Primary RAC:- FAL_SAERVER='PROD1','PROD2'
These parameters are dynamic, so that you can alter them at any time.

Differences in creating a Standby database in RAC

Hi All
   SO...: Solaris 11 SPARC 64
   DB...: 11.2.0.3.6 (64 bits)
   My experience regarding creating Physical Standby Databases is restricted in only single instances to single instances. I am reading the book "Oracle Database 11g Release 2 High Availability", but, in parallel, i would like to hear from the experienced DBAs here some opinions and recomendations in how to implement a RAC to RAC solution. Below are my doubts:
   1) In single instance, using RMAN Backup to create the Physical Standby, i have to create manually a static Listener Entry. But in a RAC env, the listener is a resource, so, i have to create that resource in the Clusterware manually, or there is other approach?
   2) I have to create a pfile and start the instance in NOMOUNT mode, but in RAC, i have to start all the nodes in NOMOUNT, or just one node is sufficient?
   3) The archives will be replicated from FRA to FRA. Is this the best approach?
   My main concern is with the Listener and SCAN questions... If you have any considerations, they will be most welcome.
   Thanks in advance.
