Display Data Guard Configuration

Hi All,
We have two Windows 2008 VMs with Oracle 11G configured as primary and standby.
This configuration has been defined by a partner who is no longer working for us.
We have broken the correct application of the redo log on the standby when we have not correctly restored some snapshots on those two VMs.
I would like to create a new Oracle server that will become the new standby. For that, I need too :
- Display the full dataguard configuration to reproduce it on the new server
- Stop (delete ?) the configuration on the primary server.
We also have the current problem that RMAN refuses to delete old archivelog since they have not been applied to the standby.
Thanks for any help about those subjets,
Eric FRIGOT

Eric FRIGOTHi,
Welcome to OTN Forums!
Then, you must restore same time snapshots both machines.
If not same time snapshots, then
1. Restore primary server snapshot.
2. Create a VM for standby again.
3. Safety remove DG configuration from Primary server.
4. Create new standby and DG configuration again.

After adding a logical standby database through Grid Control for a RAC database, I noticed sometime later the Data Guard configuration disappeared from Grid Control. Not sure why but it is gone. I did notice that something went wrong with the standby creation but i did not get much feedback from Grid Control. The last thing I did was to view the configuration, see output below.

Here are the steps followed to add the standby database in Grid Control
Maintenance tab
Setup and Manage Data Guard
Logged in as sys
Add standby database
Create a new logical standby database
Perform a live backup of the primary database
Specify backup directory for staging area
Specify standby database name and Oracle home location
Specify file location staging area on standby node
At the end am presented with a review of the selected options and then the standby database is created
Has any body come across a similar issue?
Thanks,

Any resolution on this?
I just created a Logical Standby database and I'm getting the same warning (WARNING: No credentials available for target ...) when I do a 'Verify Configuration' from the Data Guard page.
Everything else seems to be working fine. Logs are being applied, etc.
I can't figure out what credentials its looking for.

Can I make a Data Guard configuration using EM console without Grid Control

Can I make a Data Guard configuration using EM console without Grid Console?
Can I download Grid Console software from Oracle website without cost?

Assuming this is for 10g,
You could use Oracle® Data Guard Broker
Even you can download Grid Control software for free from Oracle site, you can't legally use it without license.

Using RAC One Node as a primary database in a Data Guard configuration

Is it possible to use RAC One Node as a primary database in a Data Guard configuration ?
Oracle doc states: "Supports Oracle Data Guard such that you can run physical or logical standby databases on it or even we can NOT run primary databases on it either if the primary databases have DG"
I guess it is not possible but can you folks confirm?
Alessio

Hmmm.... still unclear.
I've submitted a comment which the documentation team should pick up :
"+This sentence : "Supports Oracle Data Guard such that you can run physical or logical standby databases on it or even we can NOT run primary databases on it either if the primary databases have DG"+
+is not very clear.+
+I can understand it upto the words "on it" but the second part of the sentence, beginning with "or even we can NOT ..." seems mangled and unclear.+
+Can you clarify whether RAC One Node can be used as :+
+a. A Primary in a DataGuard configuration+
+b. A Standby in a DataGuard configuration ?+"

Problem with logminer in Data Guard configuration

Hi all,
I experience strange problem with applying of the logs in DataGuard configuration on the logical standby database side.
I've set up the configuration step by step as it is described in documentation (Oracle Data Guard Concepts and Administration, chapter 4).
Everything went fine until I issued
ALTER DATABASE START LOGICAL STANDBY APPLY;
I saw that log applying process was started by checking the output of
SELECT NAME, VALUE FROM V$LOGSTDBY_STATS WHERE NAME = 'coordinator state';
and
SELECT TYPE, HIGH_SCN, STATUS FROM V$LOGSTDBY;
but in few minutes it stoped and quering DBA_LOGSTDBY_EVENTS I saw the following records:
ORA-16111: log mining and apply setting up
ORA-01332: internal Logminer Dictionary error
Alert log says the following:
LOGSTDBY event: ORA-01332: internal Logminer Dictionary error
Wed Jan 21 16:57:57 2004
Errors in file /opt/oracle/admin/whouse/bdump/whouse_lsp0_5817.trc:
ORA-01332: internal Logminer Dictionary error
Here is the end of the whouse_lsp0_5817.trc
error 1332 detected in background process
OPIRIP: Uncaught error 447. Error stack:
ORA-00447: fatal error in background process
ORA-01332: internal Logminer Dictionary error
But the most useful info I found in one more trace file (whouse_p001_5821.trc):
krvxmrs: Leaving by exception: 604
ORA-00604: error occurred at recursive SQL level 1
ORA-01031: insufficient privileges
ORA-06512: at "SYS.LOGMNR_KRVRDREPDICT3", line 68
ORA-06512: at line 1
Seems that somewhere the correct privileges were not given or smth like this. By the way I was doing all the operations under SYS account (as SYSDBA).
Could smb give me a clue where could be my mistake or what was done in the wrong way?
Thank you in advance.

Cloud 12.1.0.4: Creating a Data Guard Configuration asymetric

Hello,
I'd like to créate a Data Guard from Cloud Console.
The primary database is a RAC of two nodes, but the standby node is one node and I dont't like to use ASM.
The wizard , ask the target node , the Standby Instance Name, but in the step 3 show this error:
No ASM instance is being managed as an EM target on the selected standby host.
To create a standby database on the selected host, an ASM instance must be added as an EM target.
Is not posible to use from Cloud this mix of storage configuration?
Thanks
Arturo

Hi,
It is recommended to use ASM on both sides. Normally OEM Expects the Current DB structures on STBY OEM.
Please follow the bleow procedure will help you.

Data Guard configuration-Archivelogs not being transferred

Hi Gurus,
I have configured data guard in Linux with 10g oracle, although I am new to this concept. My tnsping is working well both sides. I have issued alter database recover managed standby using current logfile disconnect command in standby site. But I am not receiving the archive logs in the standby site. I have attached my both pfiles below for your reference:

Data Guard Configuration Issue / ORA-16047

So last night I decided to setup a test Physical Standby database. I had everything working correctly and when I started playing around with the Data Guard Broker I started having some problems. Now I can't get the logs to ship from the primary to the standby.

ORA-16047: DGID mismatch between destination setting and target
databaseThe error description is:
Cause:       The DB_UNIQUE_NAME specified for the destination does not match the DB_UNIQUE_NAME at the destination.
Action:     Make sure the DB_UNIQUE_NAME specified in the LOG_ARCHIVE_DEST_n parameter defined for the destination matches the DB_UNIQUE_NAME parameter defined at the destination.As you can see from above the DB_UNIQUE_NAME in the LOG_ARCHIVE_DEST_2 parameter matches that of the standby database.
Also DG_BROKER_START is set to false on both the primary and standby databases.
Finally, I've removed all the drc* files from the $ORACLE_HOME/dbs directories on both the primary and standby servers to ensure the broker is not configured.
Where did I go wrong? How can I get the standby caught up and working correctly again?
I apologized if I missed anything. I'm relatively new to standby databases.

Centinul;
I have noticed a couple things
1. If you are running the query below from the standby you will probably always get the results you posted
SELECT sequence#, applied from v$archived_log order by sequence#;
What I do if run this from the primary and I add the "DEST_ID" column to the query.
2. You might have better luck finding GAPS using these queries:
select max(sequence#) from v$archived_log where applied='YES';
select process,status from v$managed_standby;
SELECT * FROM V$ARCHIVE_GAP;
3. You are mixing SQL results with Data Broker, that can bite you. Not sure where you went wrong but I would create PFILE versions at both ends before trying to Data Broker. The you can review each setting and avoid issues before adding Data Broker. Data Broker will take control and you may even find it adds entries to your parameter file.
The ORA-16047 is probably database parameter related and this should at least help answer the question. For example you might be missing log_archive_config on the Standby or soething. Comparing the two PFILE's should narrow this down
I checked my Data Broker notes but did not find an ORA-16047, I managed ORA-01031, ORA-16675, ORA-12514, and ORA-16608.
For me I decided it was a good idea to run Data Guard without Data Broker at first until I got the feel of it using SQL.
Last of all if you have not already consider buying Larry Carpenter's "Oracle Data Guard 11g Handbook" In my humble opinion its worth every penny and more.

Oracle data guard configuration for primary and standby db_name

I am working on configuring an active data guard for one primary DB and one standby DB. I have a few questions:
1. Can I use different db_name, db_unique_name and instance_name for primary and standby. For example: primary(db_name, db_unique_name and instance_name)=chicago. When I create standby DB with Rman backup and copy of pfile and control file from primary DB or use Grid control to create standby database. Oracle document or Grid control all keep standby db_name=chicago. Only make standby db_unique_name and instance_name=boston. Due to my application system condition, I want to make db_name=boston, not keep it as the same as primary=chicago. Is this valid configuration?
2. In primary datafiles, application system generate datafile name like this: hr_chicago_01.dbf, fn_chicago_01.dbf. When I move datafiles to standby server, if I plan to use db_name=boston for standby DB, can I rename datafiles as
hr_boston_01.dbf, fn_boston_01.dbf? In this way, datafile name match up with db_name. but I will create standby log group and members on primary and standby identically. If in future switching over, DB will not have problems.
3. If I don't use primary DB backup. Instead, I copy all datafiles, redo_log files (no control files) to standby. Then "alter database backup controlfile to trace" from promary and also " create pfile='/xxx/initSTANDBY.ora' from primary. Then modify init.ora and controlfile. Then run control.sql to bring standby DB up. After that, configure redo log shipping and apply with data guard or SQL. Is this a acceptable way to create physical standby DB?
Please advise your comments. Thanks in advance.

I want to make db_name=boston, not keep it as the same as primary=chicago. Is this valid configuration?NO. DB_NAME must be the same ("chicago") at both sites. The Standby will be using a different DB_UNIQUE_NAME (e.g. "boston") and can be using a different Instance name / SID (e.g. "boston").
can I rename datafiles Yes. The database file names can be changed.
If I don't use primary DB backup. Instead, I copy all datafiles, redo_log files (no control files) to standbyWhat is the difference between the first sentence (a backup of the primary) and the second sentence (a copy of the primary) ? A Copy is a backup.
Are you intending to differentiate between an RMAN Backup and a User-Managed (aka "scripted") backup ?
Normally, for DataGuard, tou can use non-RMAN methods to copy the database but there's no value add in this.
You'd still have to setup DataGuard ! (and I wonder if you'd have complications setting up Active DataGuard).
But remember that you MUST create the Standby controlfile from the Primary and copy it over to your Standby -- particularly as you are planning to use DataGuard. This is not created by 'alter database backup controlfile to trace' , but by 'ALTER DATABASE CREATE STANDBY CONTROLFILE AS 'filename''

Data Guard Observer with out Data Guard configured

Hi, we are using manual log shipping and applying (scripts) to maintain the DR (physical standby). can I use Data Guard observer to monitor my dr and live and take actions when the primary database is unavailable?
Thanks and Regards

No.
Observer needs a Broker configuration. A Broker configuration is designed for Data Guard. If you are using the EE version of Oracle you could switch to Data Guard and make these pieces work together.
Observer is a Data Guard Broker Component. You use DGMGRL to manage the observer.

Upgrading 9i Data Guard configuration to 10gR2

I have a question on upgrading to 10gR2 with respect to Data Guard. We currently have physical standby databases for our production databases in 9i (9.2.0.7). We are about to upgrade to 10g within the next quarter. At this time we are not using RMAN for backups. I recently attended a 10g Grid Control class and I believe that the instructor mentioned that to use Data Guard in 10g/Grid Control that we must use RMAN. Is this a correct statement? Is RMAN required to use Data Guard in 10gR2?

Never done a upgrade like that, so I would never know.
But Maybe rman is required.

Building Data Guard configuration in Grid controller

Hello!
First off i would like to say that i dont support creating a standby database in the Grid Controller, i would like to do it myself, "manually". But this task for me is to confirm documentation for another department that would like to know how this works, thus i need to get it to work myself. My personal thoughts is that problem might occur and it doesnt matter if i document my top 10 problems, some other might still affect them and they cant fix it. But well, to my problem:
OS: WIN 2003 Server
Oracle: 10.2.0.4
This is what happend at the end during standby createment, it is just before it will restore the controlfiles to standby host:
SQL> Disconnected from Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bit Production
With the OLAP, Data Mining and Real Application Testing options
SQL Error: ORA-12505: TNS:listener does not currently know of SID given in connect descriptor (DBD ERROR: OCIServerAttach)After grid has failed to create the standby, the services are in a blocked state. When i reload lsnrctl, its ready. When i try to create standby database again, i have to remove Windows Service (or else it wont accept me trying to create a standby with that same name). Problem is that grid is creating this service, but its get blocked right away and he cant continue.
The tnsnames and listeners.ora are fine since i can remote connect between them.
Anyone that has come across the same problem?
Best, J

Hello,
On Primary host i have 1 listener, multiple oracle homes, multiple primary databases
On standby host i have 1 listener, multiple oracle homes, multiple standby databases
And they all work fine, and were created in OEM just the same way im doing it now (thus im confirming its documentation)
The tnsping works fine.
Because the OEM is doing all the work, im not really suppose to do alot of stuff before or after. The OEM stops just before he is going in to create the control files. With the same error as stated above. Witch is kind of bullshit since OEM has already been in and restoring datafiles and another stuff that demands sqlplus connection.
Since i can reach both nodes thru sqlplus (standby -> primary and vice versa) it seems to me that my listener conf is okey.
I dont have any instance up and runing either, so i cant register any database.
God this tool oracle created, suppose to be easy but it sucks hard, it doesnt give any information why it did stop (other than what i posted), i could do this manually mutch easier (for me, but not for non oracle users). But this is a situation i cant change.
:(

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.

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 advance

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/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!

If this behavior new in this versión?
How can I revert to the classic max performance configuration, where only send the archive when it is full.
Thanks
Arturo

>How can I revert to the classic max performance configuration, where only send the archive when it is full.
That is ARCH shipping. The default in 11.2 and above LGWR shipping. So LGWR ships the redo immediately. The only thing with ASYNC is that it doesn't wait for the Standby to acknowledge before it returns a COMMIT to the user. In a low-load environment, if the standby can apply the redo fast enough, ASYNC is virtually the same as SYNC. That is MaximumPerformance becomes the same as MaximumAvailability. Only when the redo load is higher than the available bandwidth or the speed at which the Standby can apply it , will you see a lag in the Standby. (To force an explicit lag, there is a separate DELAY parameter).
ARCH shipping is deprecated.
