Active Dataguard with FSFO

We have an 11gR2 database with physical standby (Dataguard with Fast start Fail over) implementation and considering the options for including Active Dataguard configuration on the above setup for using standby database for reporting.
Has anyone configured 'Active dataguard' with combination of FSFO, any pointers on lessons learnt or limitations on this combinations would be greatly appreciated.
Thank you very much for your time.

An issue with Active Data Guard is the design of service level agreements. In the event of failover, service will degrade - perhaps dramatically. Clients are often very keen to bring the standby into use because it appears to be a way of saving money, but what will you do if it is activated? Your SLA will have to state either that the query service will be disabled, or that both the r/w and the r/o services will continue to be available, but at greatly reduced performance (which you must quantify). You need to get the client's agreement and document this.

DataGuard with RMAN

Dataguard and RMAN.
Got Active DataGuard on a primary database, quite nicely sending its archive logs to its secondary.
I can quite happily use the Broker and switchover between them.
Now if I take RMAN backups of the primary database, if I have to failover to the secondary, I'm gonna loose all those backups.
Well, I can restore the whole database to the backup, cos I can restore the control file, from the backuip and therefore I can restore the whole db.
But if I want to restore to a tablespace, I wont be able to , cos the db_unique_names names are different, and the DB ID's will be different.
Same goes if I use a recovery catalog....
so how do I failover/switchover without loosing my previous rman backups ??

If I were backup up to Disk than I would come later and back up the back ups to Tape.
Since a Standby and Primary are the same database with the same DBID you can backup from either server.

TAF On 11g DataGuard with FSFO

Hi All,
Today, i have created TAF for my 11.1.0.7 Oracle database running on RHEL 5.4 64 bit.
I have configured my databases with FSFO enabled. (MaxAvailibility with LGWR SYNC AFFIRM transport)
I created TAF with following entries:
1) Created and enabled a dedicated service in primary :
I have local_listener parameter set in my primary and standby databases.
begin
dbms_service.create_service('taf_test','taf_test');
end;
begin
DBMS_SERVICE.START_SERVICE('taf_test');
end;
begin
dbms_service.modify_service
('taf_test',
FAILOVER_METHOD => 'BASIC',
FAILOVER_TYPE => 'SELECT',
FAILOVER_RETRIES => 200,
FAILOVER_DELAY => 1);
end;
/2) Made sure that listener is listening to above created service:
lsnrctl services l_payee1fe_dg_001
LSNRCTL for Linux: Version 11.1.0.7.0 - Production on 21-JAN-2010 09:52:27
Copyright (c) 1991, 2008, Oracle. All rights reserved.
Services Summary...
Service "taf_test.us" has 1 instance(s).
Instance "payee1fe", status READY, has 1 handler(s) for this service...
    Handler(s):
      "DEDICATED" established:13 refused:0 state:ready
         LOCAL SERVER3) TNS Entry :
taf_test.us=

        (ENABLE=BROKEN)
        (ADDRESS_LIST=

                (LOAD_BALANCE=YES)
                (ADDRESS=(PROTOCOL=TCP)(HOST=payee1fe-orasvr.db.us.com)(PORT=58003))
                (ADDRESS=(PROTOCOL=TCP)(HOST=payee1fe-orasvr.db.us.com)(PORT=58003))
        (CONNECT_DATA=
                (SERVICE_NAME = taf_test.us)
)4)Trigger for setting service on appropriate primary database :
create trigger taf_test after startup on database
declare
v_role varchar(30);
begin
select database_role into v_role from v$database;
if v_role = 'PRIMARY' then
DBMS_SERVICE.START_SERVICE('taf_test');
else
DBMS_SERVICE.STOP_SERVICE('taf_test');
end if;
end;
/5) Ran a big SELECT on primary and after 5 sec, kill primary's pmon to do fail-over.
6) After sometime, i saw that SELECT was hanged for some time and once, DGMGRL has open new primary (org standby), startup trigger got fired and SELECT started fetching rows from the point where it hanged.
In that way, my TAF was working properly as expected.
My question is :
How come new Primary got the session state of SELECT which originated on old primary and then failed-over to new primary ? I confimed that,SELECT was NOT re-executed on new primary and started fetching rows from the row where it hanged at the time of fail-over.
Since both the databases have different cache and controlfiles, i want to understand how TAF works on dataguard.
In RAC,there is always a GRD through which session state can be co-ordinated between different instances. But this is not the case in DG.
I did not find anything in PRIMARY's alert log. Though STANDBY alert log was containing below statement:
ALTER SYSTEM SET service_names='taf_test' SCOPE=MEMORY SID='payee1fe';Can anyone shed light on internal working of TAF in DG.

Hi,
Just now i tested,SELECT FAIL-OVER for SELECT with PARALLEL (4) hint. I got below msg and SELECT did not executed on new primary:
ERROR:
ORA-25401: can not continue fetches
4350 rows selected.However, i observed that the session is failed-over to new primary. After getting above msg in SQLPLUS window, when i saw number of slaves given to my new sessions, i got :

Use dataguard with applications built with APEX

Hi all,
I have questions about APEX with Dataguard. Can I develop an application with APEX and then use Dataguard? Can the application switch to Standby Database automatically when there is a failover event?
If it is possible, Can you explain me?
Thank in advance
Vincenzo

APEX should work fine in a Physical Standby as it's an exact copy of your database. Logical Standby should work too, but you need to make sure the FLOWS_ schemas are being replicated and there is no transformation done to them. Also not sure if there are any datatypes in APEX that would not work in a Logical Standby, but you should be able to look those up in the Data Guard Docs then query all_tab_columns where table_owner like 'FLOWS_%' to verify. Physical Standby would be a safer bet.
You want to make sure you install your HTTP server on a different server so it doesn't go down with your database in the event the OS shuts down. Then in the TNS entry for your database you can add [url ="http://download.oracle.com/docs/cd/B19306_01/network.102/b14213/tnsnames.htm#sthref676"]failover=on and the additional IP address(es). This will automatically failover when your primary database is no longer accessible. Personally I would have a second HTTP Server installed at your backup site and handle the failover at the network level. If a sprinkler head pops or your air conditioner fails at your primary site, everything is going to stop there. You can easily have 2 HTTP servers accessing the same APEX install (on one database) at the same time, so it's easy to test / verify the state of the 2nd http server. You'll probably want to mirror the /i/ directory and any image directories you have for your applications from your primary site to your failover.
"Automatically"? Yes, all of this can be configured to happen automatically, but most people (Tom Kyte included) recommend that you only failover manually as it's best to investigate the underlying issues with your primary site before failing over. You should be able to tell within the first 5 minutes whether the problem was a simple network outage or unintentional OS reboot, or a more serious problem such as a corrupt block, Air Conditioning failure, hardware issues, etc. Keep in mind to do automatic failover you need a 3rd site as an observer of your 2 sites to decide which site is "still alive".
Varad, I believe TAF is only a RAC concept, not Data Guard. Furthermore, I'm pretty sure that TAF is not built into APEX. So, in an APEX / RAC installation, if you're running a page that takes say 4 seconds (long running report) and 2 seconds in the database node on which you are running fails, the end user is likely going to see a "404 not found" or some other error, then when they refresh the page it will hit another RAC note and return the results. I'm pretty sure the TAF logic is not built into APEX or mod_plsql to migrate the database session to a new surviving node when it detects a failure. Again, I could be wrong, but I'm pretty sure I'm not in this particular case (someone please prove me wrong).
Thanks,
Tyler

Configuring maximum protection mode in dataguard with oracle 10g

Dear All,
I am facing a big problem in my configuration for oracle dataguard in maximum protection mode. as per oracle documentation i have done the following.
on the primary database i configured the floowing parameter.
LOG_ARCHIVE_DEST_2='SERVICE=CDER LGWR SYNC AFFIRM
VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE)
DB_UNIQUE_NAME=CDER'
on the standby i configured the following parameters.
LOG_ARCHIVE_DEST_2='SERVICE=REDC LGWR SYNC AFFIRM
VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE)
DB_UNIQUE_NAME=REDC'
i created standby redo logs on the standby database as per documentation.
I shut down the primary database and started it in mount stage and i executed the following commands.
SQL> ALTER DATABASE SET STANDBY DATABASE TO MAXIMIZE PROTECTION
after database was sucessfully alterd, i execute it the following command to open the database.
SQL > ALTER DATABASE OPEN;
what is happening is that i am recieving the Error end of communication channel and also after i look at the log file the following error is in place
Thu Jul 22 23:33:37 2010
Errors in file c:\oracle\product\10.2.0\admin\redc\bdump\redc_psp0_1088.trc:
ORA-16072: a minimum of one standby database destination is required
though when i reset the dataguard to maximize performance it work really successful and the database open;
please guys guide me through this

DataGuard with Oracle 11gR2

Hello All,
I need to know the configuration steps that need to be applied on the primary database and the standby database in a datagurad environment.
Is there any quick links instead of reading the whole Dataguard administration guide?
I need to know the steps that need to be applied in general.
Regards,

Dataguard with 11g Standard Edition

Hi, We have 11g standard edition. I wish to provide high availability. From the license document We are able to setup Basic Standby Database(Manually Managed). What is difference between Data guard and Basic standby? Hw can i configure? What r all the requirements? Any other possible ways?

Thanks. That document is very useful for me. That document contains Version: 8.1.7.4 to 10.2. But i have 11g. Is this applicable for 11g also.

Unable to resync dataguard

Hi everybody!
I have a problem. Some weeks ago I opened a post related to this issue. We have two dataguards with dataguard broker. One of them is resync (thanks to mseberg and this forum) and now I have problems with the other.
Once I have learned how to configure and start/stop dataguard broker, I have a more basic problem, which is to resync it. I follow a process, where I backup the primary with RMAN, I copy the rman files to the other server with the controlfile, at once, I recover with rman again.
The problem is that it is too big, 2 hours for backing it up more or less, and when I restore it, no archivelog list appears being syncronized.
I have followed the same process than the other one and I can't resync it. I think there is something at my params or something new at 11g version...

Dataguard in a replicated environment

Folks,
Has anyone implemented dataguard(standby database) in a replicated environment
or
worked in an environment where replication (updateable snapshots) are in place already along with dataguard?
Are there any complications I need to be aware of whilst setting-up dataguard with replication on?
Thanks
Amit

That is entirely due to the checkpoint delay. Depending on variations in hardware,
I/O configuration and workload, it can take clients longer to flush their caches than
the master. You can adjust the delay, which is 30 seconds by default, by calling
the DB_ENV->rep_set_timeout API with the DB_REP_CHECKPOINT_DELAY flag.
If you set it to 0, there will be no delay.

Oracle Streams - Dataguard Configuration

Dataguard<------Streams<----Production------> Dataguard
I'm planning to implement a 4-way System where My Production Database with its own Physical Standby will be streaming(Streams database) to A reporting Database with its own Physical Standby.So,Effectively My production database,Especially it's redo logs will be put under severe load.I would like get some light on the feasibility of such a Setup.What parameters can i Take care of so as to make it a profitable High Availability-High Preformance System?
Any suggestions and advice will be highly appreciated..

Remember that Streams check the source DB name of the LCR. Thus the db_name of each standby must be the same as the of the open DB of the remote DB will reject the LCR of the standby when it is activated.
Also streams, dataguard and crash don't fit so well in respect of streams consistency. At the crach time, some transaction will be lost that would have already been sent by streams, since streams react beneath the second. Thus when you activate the dataguard with its loss of some data, you are going to miss some source transaction, that would have already been replicated. You may end with errors on target site, either being dup val on transaction or OLD value in target do not match new value in LCR.
You can't avoid 100% this but you can decrease its extend. Use as method the 'LGW asynct' as dataguard destination.
LOG_ARCHIVE_DEST_2='SERVICE=boston LGWR ASYNC'
http://download.oracle.com/docs/cd/B19306_01/server.102/b14239/log_transport.htm#i1265762
This requires to create the standby redo logs on the dataguard DB (and also on the source DB, since it may becomes itself the standby) so that LGWR updates the remote redo as soon as it can ('async' otherwise 'sync' means that the commit on source is done AFTER the commit into the dataguard and you don't want that).
From my own observation the 'LGWR async nowait' lag usually under 1 sec behind production, which is very good.

Monitoring Dataguard on 10g through OEM

Please,
Should I need to install a version of OEM to monitore my dataguard on 10g.
I configure Dataguard with Oracle 10g running on windows, but the GUI of OEM doesn't show a tab related to dataguard.
How should I get it ?, there is a link of that should help me to resoleve this issue?
Thanks

we monitor from console using SYS userYou have to monitor it using a SYSDBA user not necessarily SYS. So you can create a user e.g. SYS_MONITOR which has different policy than SYS. Although it is best to change that password on regular bases too, maybe every 3 months.
so is any way we can change SYS password on console using command line utility?I don't get your question. Are you asking if it is possible to change the monitoring username/password using some command line utility? If so, I haven't heard of such tool. But there could be a package like MGMT_TARGET which you can manipulate the credentials if you know how to use it.

RAC with real time knowledge

Hi, I'm interested in learning RAC and dataguard with real time knowledge......... please help me finding some training institution or peoples with real time knowledge
Thanks

The term "+real-time+" has a very specific meaning in Information Technology. See http://en.wikipedia.org/wiki/Real-time_computing for the basic details.
Oracle RAC is not a real-time database.. and nor does the "real-time knowledge" make much sense IMO...
Always difficult to get to grips with the nuances of the English language where it is your 2nd or even 3rd language. But it is important that we speak the same language and understand the same terms and concepts, in Information Technology.

Oracle dataguard configuration command

Hello,
Can any one provide me the command that is used to configure dataguard that will get the primary database to be connected to it standby database?
any way How do you configure database into dataguard with standby database?
What are the SQL command use to configure dataguard?
How to configure dataguard using Enterprise Manager?
Thanks
Alain

Perhaps you could find the answers you seek in the fine Oracle® Data Guard Concepts and Administration guide.
