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):

Hey
thanks for the answer. I followed you recommendations but I got the same error again. I restored/recovered the old status and looked deeper into the dgmgrl configuration before enabling. I found an interesting point. (show database verbose ALPHAx)

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?

  • Problem with data guard Creating a Physical Standby Database turorial

    There is a tutorial of Creating a data guard Physical Standby Database:
    http://www.oracle.com/technology/obe/11gr1_db/ha/dataguard/physstby/physstdby.htm
    I tried to install it on two servers. One for primary database second for physical standby.
    I have error on C. Creating the standby database over the network, action #6:

    I'v checked listener and it is runned. There is no service for database because there is no database yet.
    The question is did some one installed data guard configuration using this tutorial? Is there any errors in it? What should I do to finish this installation?

    On Windhose for every instance a service must have been created using the oradim command.
    Oracle tutorials are usually Unix-centric, as Windhose is an odd man out, so they don't discuss that bit.
    'Kindly do the needful' and create the service prior to starting the instance in nomount mode
    Hint: oradim is documented and has a help=y clause.
    IIRC there is an option in database control (in the maintenance part) which automates everything.

  • 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?
    Thanks for help,

    Hi, 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/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!

    Hi,
    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.

    Without Data Guard Broker:

    With Data Guard Broker:
    http://www.oracle.com/pls/db112/to_toc?pathname=server.112/e17023/toc.htm
    See especially why you want to use the broker:
    http://download.oracle.com/docs/cd/E11882_01/server.112/e17023/concepts.htm#i1013106
    In short: You should have a good reason if you do not use the broker, because it is the officially recommended way to maintain Data Guard. It is even required for some features like Fast-Start Failover.

    Hi,
    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.

  • 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.

    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)

    (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.

    Operation requires startup of instance "primary" on database "PRIMARY"
    Starting instance "primary"...
    ORACLE instance started.
    Database mounted.
    DGMGRL> EDIT DATABASE 'STANDBY' SET PROPERTY LOGXPTMODE='SYNC';
    Property "logxptmode" updated
    SQL> alter system set undo_retention=3600 scope=both;
    System altered.
    SQL> show parameter undo
    NAME TYPE VALUE
    undo_management string AUTO

    DG broker is the way to go. There are only minor points you can't control - like when you have standby redo logs and no redo application delay, dg broker will always start real-time apply.
    Also, DG broker is the only way if you want fast-start failover (10gR2 feature).
    What is the latency of your nework, especially under load? Add this latency to each commit - will the commit time be acceptable? If not, you cannot use sync.
    What version do you use? In 10gR1, there are issues with async - there is only about 50MB buffer, and if you get such backlog, even with async commit will wait for standby. (In 10gR2 this is solved, async will read from disk redo logs.)
    NET_TIMEOUT - set it low for sync (so commits won't hang long), higher for async. Default is 180 seconds, Oracle recommends minimum value to 10 seconds. I would start with 10 sec for sync, 180 for sync. The main question is, how reliable your network is, and how long brownouts you want to survive without affecting data protection (with the expense of performance).
    Regarding the proper setting of all bells and whistles of archive_log_dest_n - I had best experience with leaving it to dg broker. Just set LogXptMode property to sync/async/arch, and let dg broker set everything else (service, valid_for, affirm, retries...).
    The authoritative source: http://www.oracle.com/technology/deploy/availability/htdocs/maa.htm#Publications
    If you are on 10.2.0.1 - 10.2.0.3, please see metalink bug 5578157, 5587231 - if sqlnet.outbound_connection_timeout is not set, the lgwr can hang even if net_timeout is set. (Yes, real-world experience:-)

  • Monitoring failover - Data Guard Broker

    Hi,
    I work on a Oracle 10.2.0.4 database on Solaris 10. It is a 2 node RAC database with a physical standby configured.
    I want to monitor (send a mail) to myself when failover occurs (which will be triggered by data guard broker ) , I think so I can monitor the failover using alert log (which normally does log the command when we initiate a failover) but I am not sure whether data guard broker also does the same( writes appropriate commands when a failover is triggered)
    Is there any other way we can come to know when a failover occurs (we can query database_role from v$dataguard status) but I am looking for some trigger that will be fired instantaneously when a failover is initiated ?
    Also is it possible to monitor the observer, whether it is up or not ?

    Hi,
    you have several possiblities to do that. Easiest is to use predefined Grid Control Events for it. Or you may put a trigger on the event "after DB_ROLE_CHANGE on database".
    Monitoring the observer can be done with dgmgrl like
    connect sys/<pw>@<cd>;
    show configuration verbose;That show you the presence and location of the observer.
    I give you an example for the usage of the trigger that starts a service depending on the role of the database. You may customize it to send you an email.
    begin
      dbms_service.create_service('safe','safe');
    end;
    create trigger rollenwechsel after DB_ROLE_CHANGE on database
    declare
      vrole varchar(30);
    begin
      select database_role into vrole from v$database;
      if vrole = 'PRIMARY' then
        DBMS_SERVICE.START_SERVICE('safe');
      else
        DBMS_SERVICE.STOP_SERVICE('safe');
      end if;
    end;

  • 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.

  • 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,
    Andy

    Hi 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,
    Andy
