Data Guard Broker configuration in oracle10g r2
Hi,
I am facing difficulties while configuring data guard broker. Our setup is RAC primary and single standby database. Show configuration is raising the following error...
ORA-16607: one or more databases have failed
on dcSTANDBY.log file it shows below messages....
NSV0: Failed to connect to remote database ajmprod. Error is ORA-12545
NSV0: Failed to send message to site ajmprod. Error code is ORA-12545.
I have checked listener.ora and tnsnames.ora are fine. It's fine with tnsping and sqlplus conection. I am confused where is the problem.
Aprreciate your suggestions.
Here is how I would look into this issue.
1. check the password file is setup for both and the password is common between them and matches the password of the sys user in the database.
2. check that listener(s) are up and running and status checks out.
3. check that you hosts file or DNS sees this hosts, you can check this with a ping command do from each host to the other
4. check that tnsnames.ora has the proper connect setup for both instances in you data guard configuration.
5. check tnsping to both instances from both hosts.
6. check all TNS connectivity to both instances using the SYS as sysdba, Use the TNS sqlplus sys@db as sysdba. Do this connection from both hosts if using more then one host.
If you have verified all this and it is still not working let me know and we can move on to next steps.

Error: ORA-16532: Data Guard broker configuration does not exist
Hi there folks. Hope everyone is having a nice weekend.
Anyways, we have a 10.2.0.4 rac primary and a 10.2.0.4 standby physical standby. We recently did a switchover and the dgbroker files automatically got created in the Oracle_home/dbs location of the primary. Now need to move these files to the common ASM DG. For this, I followd the steps from this doc:
How To Move Dataguard Broker Configuration File On ASM Filesystem (Doc ID 839794.1)
The only exception to this case is that I have to do this on a Primary and not a standby so I am disabling and enabling the Primary(and not standby as mentioned in below steps)
To rename the broker configuration files in STANDBY to FRA/MYSTD/broker1.dat and FRA/MYSTD/broker2.dat, Follow the below steps
1. Disable the standby database from within the broker configuration
DGMGRL> disable database MYSTD;
2. Stop the broker on the standby
SQL> alter system set dg_broker_start = FALSE;
3. Set the dg_broker_config_file1 & 2 parameters on the standby to the appropriate location required.
SQL> alter system set dg_broker_config_file1 = '+FRA/MYSTD/broker1.dat';
SQL> alter system set dg_broker_config_file2 = '+FRA/MYSTD/broker2.dat'
4. Restart the broker on the standby
SQL> alter system set dg_broker_start = TRUE
5. From the primary, enable the standby
DGMGRL> enable database MYSTD;
6. Broker configuration files will be created in the new ASM location.
I did so but when I try to enable the Primary back I get this:
Error: ORA-16532: Data Guard broker configuration does not exist
Configuration details cannot be determined by DGMGRL
Form this link,(Errors setting up DataGuard Broker it would seem that I would need to recreate the configuration....Is that correct ? If yes then how come Metalink is missing this info of recreating the configuration... OR is it that that scenario wouldnt be applicable in my case ?
Thanks for your help.Yes I can confirm from the gv$spparameter view that the changes are effective for all 3 instances. From the alert log the alter system didnt throw u pany errros. I didnt restart the instances though since I dont have the approvals yet. But I dont think thats required.

Remove Data Guard Broker configuration file
Hi,
We have a data guard configuration running on Oracle 10g RAC (2 nodes) ASM. After failover, we rebuild the old primary as physical standby. But every time when enable the data guard broker, it created problems. So the best solution for us seems to completely remove the data guard broker configuration and recreate them. Here are our steps
On both primary and standby
1) alter system set DG_BROKER_START=FALSE
2) shutdown database
3) use asmcmd command to remove the broker directory under +DATA/dbname/DG_BROKER
4) start the database
5) alter system set DG_BROKER_START=TRUE
6) go through the many steps to recreate data guard broker configuration
I am just curious whether this is the right way and whether there is any simple way?
Thanks in advanceHi, I saw same issue when doing switchover testing in my lab environment.prerequisite is primary role and standby role switched and og can be applied without data guard broker.
Here is the step I resolved the issue
1)on both primary and standby database
SQL> alter system set dg_borker_start=false;
on primary DB:
SQL>alter system set dg_broker_config_file1='?/dbs/dr1afterswichoverpry.dat';
SQL>alter system set dg_broker_config_file1='?/dbs/dr2afterswichoverpry.dat';
on standby DB:
SQL>alter system set dg_broker_config_file1='?/dbs/dr1afterswichoverstby.dat';
SQL>alter system set dg_broker_config_file1='?/dbs/dr2afterswichoverstby.dat';
2) enable dg_borker_start on both primay and sandbby db
SQL> alter system set dg_borker_start=true;
3)on primary database to create configuration
Hope this can help you!

How to remove data guard broker configuration when ORA-16625?
I setup data guard broker for a standby database. However, we recreate the database and re-setup the standby database. But find the earlier broker configuration still exists. But I cannot remove or disable the configuration or any database within the configuration. When I try to do so I got the error, although all network settings are correct:
Error: ORA-16625: cannot reach the database
How to remove the configuration at this stage?

Edited by: Monto on Dec 19, 2012 1:23 PMHi,
I removed the configuration and removed the broker files from RAC primary(mvmxp2) and single instance standby(mvmxs2) and re-created back.i tried it many times but getting error "ORA-16532" .I needed to have this standby backup before i start upgrading the primary.

Configure data guard broker on Oracle 11.2.0.1
Our primary is a 3 node RAC of 11.2.0.1 on Redhat 5.2. The physical standby is a single instance on redhat 5.2. After configured data guard, I am trying to configure data guard broker following docOracle® Data Guard Broker 11g Release 2 (11.2)

Listener failed to start. See the error message(s) above..Without the Listener and SID_LIST_LISTENER entries, the grid infrastucture appear to manage a default listener and works OK. After add these, it appears to conflick with the default setting. I also tried to add a different listener name, then I got messge LISTENER is already startedHow should one handle this problem?
Thanks.Shutdown the listener and check for white spaces in the file. Try to restart it. If if fails review against my example below.
Here is my working example:
PRIMARY
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = primary.myserver.com)(PORT = 1521))
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0)
(PROGRAM = extproc)
(SID_DESC =
(global_dbname = PRIMARY_DGMGRL.myserver.com)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0)
(SID_NAME = PRIMARY)
STANDBY
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = standby.mydomain.com)(PORT = 1521))
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0)
(PROGRAM = extproc)
(SID_DESC =
(global_dbname = STANDBY_DGMGRL.mydomain.com)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0)
(sid_name = STANDBY)
ADR_BASE_LISTENER = /u01/app/oracle
INBOUND_CONNECT_TIMEOUT_LISTENER=120
When I first tried to setup this up several months ago I had this issue:
ORA-12514 during SWITCHOVER
Problem: You perform a switchover using DGMGRL. Though the switchover itself completes successful, databases don't get started up again. Instead, DGMGRL output holds an
ORA-12514: TNS:listener does not currently know of service requested in connect
Cause: This is a configuration issue: DGMGRL needs a special entry in the listener.ora.
Solution: Details on this can be found in the Metalink note 308943.1. Make sure both, your primary and standby database have an explicit entry in the listener.ora like this:
SID_LIST_LISTENER = (
SID_LIST = (
SID_DESC = ( GLOBAL_DBNAME = <db_unique_name>DGMGRL.<dbdomain> )
( SERVICE_NAME = <db_unique_name>.<db_domain> )
( SID_NAME = <ORACLE_SID> )
( ORACLE_HOME = <ORACLE_HOME> )
Take special care, that:
* <db_unique_name> reflects the databases unique name (SHOW PARAMETER db_unique_name)
* <db_domain> reflects the databases domain (SHOW PARAMETER db_domain)
* <ORACLE_SID> and <ORACLE_HOME> reflect the corresponding settings of the database
Having adjusted your listener.ora files, restart the listener (lsnrctl stop && lsnrctl start). Give your databases a few minutes to register with the listener again, and then - just to be on the safe side - let the listener tell you its configuration: lsnrctl status && lsnrctl services. Check the output if everything matches.

Help for configuring Data Guard Broker
Hi All,
Can any body help me in configuring data guard broker for oracle 9i on windows.
What are all requirements needed. I already configured physical standby database.
I did this is on my laptop using vm-ware. One node is having Primary database and
second node is having standby database. Now I am planning to use DG broker on primary node.
Regards
KiranHere's the help you need:

Without version information (what does 9i mean?) no further help is possible.
Please also be advised that VMware is unsupported so if you run into issues you are on your own. -
Parameters need to configure Data Guard with Data Guard Broker
Hi gurus,
I'm following this guide http://www.oracle.com/us/solutions/sap/wp-ora4sap-dataguard11g-303811.pdf, but it isn't clarify what parameters we need to set to get the service up.
I noticed that we can setting up for two ways, either Oracle Enterprise Manager or Data Guard Broker. Do we need to configure the same parameters to OEM and after to activate the DGMGRL?
Can you help me?
Thanks,
Denis

Data Guard Broker and Cold Failover clusters
Hi,
I wanted to use Data Guard Broker to control primary/standby systems on AIX clusters but found that without Oracle clusterware it is not supported on failover of a database to another node (unless you drop and recreate the configuration which in my opinion is not support at all!).
The 11g documentation states that DG Broker offers support for single instance databases configured for HA using Oracle Clusterware and "cold failover clusters".
Does anyone know whether this support for cold failover clusters in 11g means "proper support" i.e the configuration detects that the hostname has changed and automatically renames it so it continues to work?, or is the support in 11g the same as that in 10g?.
Thanks,
AndyHi Jan,
We already use virtual hostnames.
When I set up the configuration the hostname for the databases default to the server name. The only way I know of changing this is to disable the configuration, then use the "edit database...set property" command but when I enable the configuration again it reverts back to its previous value.
regards,

Data Guard Broker connecting to standby database fails
Hello everybody
I checked lots of pages but I'm not able to find a solution für my problem. I already set up a primary and a standby database (prim = ALPHA1 / standby = ALPHA2).
After enabling my dgmgrl configuration I got two errors:
DGM-17016: failed to retrieve status for database "alpha2"
ORA-16664: unable to receive the result from a database
The dg log from ALPHA1 says:
06/04/2013 16:06:57
Site alpha2 returned ORA-16664.
Data Guard Broker Status Summary:
Type Name Severity Status
Configuration alphadgb Warning ORA-16607
Primary Database alpha1 Success ORA-00000
Physical Standby Database alpha2 Error ORA-16664
While the dg log from ALPHA2 (standby) says:
06/04/2013 16:43:28
SPFILE is missing value for property 'LogArchiveFormat' with sid='ALPHA2'
Warning: Property 'LogArchiveFormat' has inconsistent values:METADATA='arch_ALPHA2_%S_%t_%r.arc', SPFILE='(missing)', DATABASE='arch_ALPHA2_%S_%t_%r.arc'
Failed to connect to remote database alpha1. Error is ORA-12514
Failed to send message to site alpha1. Error code is ORA-12514.
How can I solve this issue? Every type of tnsping is successfull. The sqlplus login from the primary to the standby database works, the other way round works too! Therefore the tnsnames and listener data seems to be correct.
My configuration for ALPHA1 (primary db):

As the listener are configured ALPHA1 (prim) should be on port 1521 while ALPHA2 (stby) should work on 1522. In the configuration of DGMGRL only appears port 1521 (look at StaticConnectIdentifier). Is this maybe the reason of the networking problems with DG Broker? How can I fix this?

Data Guard Broker fails with ORA-16635 and ORA-03135
Hi All,
I configured Oracle RAC with Dataguard 11.2 on Windows 2003.
I've already configured Standby without Data Guard Broker and everything is working fine, but when I try to use Data Guard Broker, he can not synchronize the files from the Data Guard Broker.
I've tried everything including MOS, but not found anything.
I'm getting this error.

Are you using firewall between Hosts?
If yes check if firewall is blocking yours connections.
Set the following parameter in the sqlnet.ora file that would be referenced by each database, primary and standby.
SQLNET.EXPIRE_TIME=n
Where n is some number of minutes. Preferably below 10. When this parameter is enabled, a small 10 byte probe packet will be sent from node to node at specific intervals.

Data Guard Broker: errors ORA-16816 and ORA-16817 with Fast Start Failover
Hi,
my environment is:
OS: Windows XP Professional Edition SP2
DB: Oracle EE 10.2.0.3
Primary db: orcl
Standby db: stby
both databases are running on the same server.
I have configured Data Guard as described in the DG Administration Guide.
In the Data Guard Broker I switch to 'stby' succesfully and 'stby' is the primary db and 'orcl' is the standby db.
I switched back to 'orcl' as primary db and I get some errors:

I have searched for solutions on Metalink and google, but with no success.
Has anyone got this kind of problem?
Any suggestions on how to resolve it?
ThanksHi DigerDBA
I did your advice , the error disappear, and thanks for your advice , but do I need to keep standby_file_management='AUTO' or 'MANUAL' in primary and standby init files?
Am asking this because when I use the observer the failover failed and I get the following error
SQL Execution error=604, sql=[ALTER DATABASE COMMIT TO SWITCHOVER TO PRIMARY WAIT WITH SESSION SHUTDOWN]. See error stack below.
ORA-00604: error occurred at recursive SQL level 1
ORA-01275: Operation ADD LOGFILE is not allowed if standby file management is automatic.
Complete Failover operation failed in the step when attempting to convert the database to be the new primary.

Data Guard Broker - Complete/Immediate Failover ???
Dear Experts,
I have been reading about Data Guard Broker from Oracle Doc's (10.2). I came across two terms: Immediate Failover and Complete Failover.
I understood from the doc's what each one of them does but unable to understand how to trigger them.
Say, I have a Data Guard configuration setup in MAXIMUM PERFORMANCE mode. My primary database dies for whatever reason. How do I trigger "Complete Failover"?
If I were to use the following command, it will perform "Immediate Failover"
DGMGRL> failover to standbydb;
OS: Any OS (as this is related to concept)
Oracle: Oracle 10g Release 2 (10.2.0.4)
Standby Type: Physical Standby DatabaseThanks for taking time in reading and answering my question.

According to the documentation at :
http://download.oracle.com/docs/cd/B19306_01/server.102/b14230/sofo.htm#CHDDIEAC
or
http://www.sc.ehu.es/siwebso/KZCC/Oracle_10g_Documentacion/server.101/b10822/siteresource.htm
the command mentioned will execute a 'Complete Failover'
The command to do an Immediate failover would be:
