I am new to data guard.I want help to implement dataguard.so can anybody tell me link for good document,video to implement dataguard.What is the version is it 10g or 11g?
is it Windows/Unix?
You can follow emre baransel mentioned documents and also some more here.
if 11g you can implement dataguard without any backup. However mentioning both the links. Go through.

How to access Data Guard option in Oracle 10g OEM

Hi All,
I have Oracle 10g ENTERPRISE EDITION on Unix envoirement. I want to setup logical standby Database through Data Guard technology. But when I brows through OEM I do not find Link for DATA GUARD????
1) How to access Data Guard option from oracle 10g OEM.
2) Does It come with Enterprise Edition OR I have to install it separately.
Regards,
Darshan

I am managing almost everything through EM Grid Control. It is easy to setup and configure.
Anyways, if you have read the documentation on
Oracle® Data Guard Concepts and Administration and setup your environment accordingly then you should not have any problems. Atleast I can assure you that your production database will not be affected by it.
Just make sure that you follow each step and read thoroughly. If you have spare machines then you can test and record your configuration before performing it on your production db. This link will provide you with the information on DataGuard.
http://download-uk.oracle.com/docs/cd/B19306_01/server.102/b14239/concepts.htm
If you think that way then you will never be able to do any new stuff since you will always fear that something might go wrong. Go ahead pal, try it on test machines and you will know that it is not that difficult.
There are real experts who help people like us in this forum and I know that they are doing a pretty good job.
All the best.

How to implement data level security

How to implement data level security in BI Publihser?. I am using Obiee enterprise edition and bi publihser. My requirement is to show data based on User- Region relation ship.
User A - belongs to Eastern Region
User B - belongs to Southern Region
so if user A logged in he should see only Eastern Region report. If user B logged in He should see only Southern region. I am using direct sql to my oralce database as data source.
i appriciate your help

I am using a common database username and password for jdbc connection. what i am looking is based the BI Publihser login, is there any way?
say i have userregion table joined with fact. so that i can write a query to get the data
select c1,c2,c3
from userregion, fact
where fact.region=userregion.region
and userregion.user = BIPUBLIHSERUSER
but my question is ithere any variable to tell who is logged in BI Publisher? Any server varaibles?
Other related question is, In every report i want to show User name who is running the report. How can i get this?

How to setup Data guard for SAP database?

Can someone please tell me how to setup data guard for SAP databases?
Thanks,
Abhi

Hi Abhi,
have a look at OSS 105047 - Support for Oracle functions in the SAP environment you find this under
14
Oracle Data Guard
You can use "Physical Standby".
You cannot use "Logical Standby".
You are allowed to use Fast Start Failover (FSFO) but SAP Support is not provided.
You can use Data Guard Broker.
You can use Maximum Performance Mode, Maximum Availability Mode and Maximum Protection Mode.
In the case of Maximum Availability and Maximum Protection, you must pay particular attention to a fast network connection in order to avoid performance problems.
Maximum Protection causes the primary database to terminate if problems occur in the standby database.
And here you find on Oracle white paper from 2010 http://www.oracle.com/us/solutions/sap/wp-ora4sap-dataguard11g-303811.pdf
Perhaps some SAP user have answers for you http://scn.sap.com/community/oracle/content?query=guard

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/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 implement "Date searching criteria"

I have a block contains some textboxes such as project_no, project_name, startdate.
I would like to search by startdate.
For example, I have 2 other text items for searching only. the first item is "DATE1" the second item is "DATE2". I want a user to enter a date into the first text item "DATE1" and enter another date into the second text item "DATE2". then click on execute button to get the result.
The result is supposed to be all StartDates that match the criteria.
How can i implement this in forms6i???
Thank you in advance for your help.

ok, i will explain more in details,
I have a data block contains some text boxes (sno, empno, projectno, startdate), currently, users can click the "Execute" button and return all records or users can go to Enter query mode and insert a value (search criteria) into any of these textboxes, and then they will get the required record after clicking the "Execute" button.
I added 2 non database text boxes(date1,date2) for searching purpose, it will return all startdates located between these 2 dates. I used the following code for that and its working fine but "IT DISABLED THE OTHER SEARCHING CRITERIA (sno, empno...)" which is not good because i want a suer to have a choice.
Declare
where_dt varchar2(150);
Begin
     IF :System.Mode = 'NORMAL' THEN
     set_block_property('blk_name', default_where,'');
     Else
where_dt:='startdate between :blk_name.date1 and :blk_name.date2';
set_block_property('blk_name', default_where,where_dt);
     End if;
Execute_query;
End;
So, i edited the code to include the other criteria, users can search by one criteria only.
Declare
where_dt varchar2(150);
Begin
IF :System.Mode = 'NORMAL' THEN
set_block_property('blk_name', default_where,'');
Else if :System.Mode = 'Query' Then
if :blk_name.Date1 and :blk_name.Date2 is not null then
where_dt:='startdate between :blk_name.date1 and :blk_name.date2';
end if;
if :blk_name.sno is not null then
where_dt:='sno = :blk_name.sno';
end if;
if :blk_name.empno is not null then
where_dt:='empno = :blk_name.empno';
end if;
set_block_property('blk_name', default_where,where_dt);
End if;
Execute_query;
End;
Unfortunately, this code is not working, i am getting error.
It points to the last "END;" and returns error: "Encountered the symbol ";" when expecting one of the following IF "
Any help please??

Data Guard Implementation Importing one schema will it reflect in other?

Hi All,
I have succesfully implemented data guard (Primary) and Physical Standby
for 10g R2.
It works fine. I would like to know if on the primary if I remove one schema and import the data/objects using a dump file will it get reflected in the standby?
ie we have to refresh our primary database with actual production data by dropping one user (prod) and its objects. And I will run the import(dump file) in order to bring the data from production
Will this refresh the data in the standby ?
Thank u all
Rajesh Alex

The answer is Yes, that's the goal of the dataguard configuration, to replicate all changes from the primary to the standby database.
Any DML or DDL is recorded by the redolog mechanism, and the redo information is transported from the primary to the standby database where the information is applied, exactly the same way it was applied at the primary database. DDL commands (create, alter, drop) are considered transactions against data dictionary tables, so they are recorded just like any other DML transaction on the redolog mechanism and transfered just the same to the standby.
The time it will take to get replicated at the standby database will depend on the kind of Dataguard configuration you have, if you have a high avilability or a high performance configuration.

Data guard implementation

Hi ALL
i want to install a data guard on windows servers.
So i got two windows servers set up.Now i need to implement data guard.
Since both the servers are new and only oracle in installed,it will be easy to implement.So before proceeding i want to take all your suggestions.
Thank you one and all........................

Hi, i recommend you read the next documentation before start with the configuration,you can design your environment careful attention to detail and get more performance in your implementation.

Init SID .ora during configuration of Data Guard - advice required

Hi All,
I am looking to implement data guard across 2 RAC clusters. One cluster will be primary and the other is for Disaster Recovery.
I have already set up the two 11g R 2 RAC clusters on RHEL 5 and now need some pointers to good docs for data guard install.
Can some one direct me to good step by step info for configuring data guard between to RAC clusters - detailed explanations of each step would be useful too, in particular around the init.ora file configuration changes between the primary and DR sites
Much appreciated
Steve

Hi Steve,
look at the MAA Whitepapers:

Data Guard ON ODA

can you please help with any documents that show how to configure Data Guard on two ODA?
Thanks,

Hello;
Based on what I read in E22692-11 its not any different than any other database with Data Guard
Both require Enterprise Edition and can be Single instance or RAC.
However given the odd size templates and the fact I search the document and cannot find one word about Data Guard concerns me a little.
But if you have two of them I don't see any reason one cannot be Primary and the other Standby.
If you dig deep on the oracle page for it you see "Active Data Guard" as an option.
Based on a hard search I think my first thought is correct. The use of Data Guard falls into "Enterprise Edition" and there's Nothing special about it on ODA. Decided which ODA template you want to use and build it.

MC Service Guard + Data Guard + Data Broker?

Hi guys,
A clustered 2 nodes on HP-UX with MC service guard (active/standby), have a running oracle 10g db in one of the nodes. I am planning to implement data guard on the 2 node. But MC service guard is responsible for failover of the nodes, which I think is the same role of data broker. Would this cause a conflict between the MC service guard and data broker failover role? Should I not implement data broker? Could anyone give me some ideas? Thanks in advance.

YES!! you can install 10g grid control under HP MC/Service guard. I have done it with some undocumented tweaking. As this is an undocumented feature, use it at your own risk.
Problem :
Installer picks up the hostname and the Management service is installed on the host instead of the package. When the package flips over to the other host the management service breaks.
Solution :
Copy the CD/DVD to the host or better still download the media from edelivery.oracle.com to your host. (I personally do not mount CD/DVD on HP servers because of the crazy pfs mounting. It tends to hang the server if you donât do it right). You will have to install from the copied media since you will be modifying one of the supplied ini files.
Edit oraparam.ini under Disk1/install in the copied installation media. Change SHOW_HOSTNAME=NEVER_SHOW to SHOW_HOSTNAME=ALWAYS_SHOW and save the file
Start the installer. During the installation there will be a screen to enter the hostname. Change the hostname to the package name. (The labels in the hostname screen did not display properly. I use Exceed. If you see a screen with your hostname in a text box, just change it to the package name and continue).
Towards the end of the installation, opmn configuration will fail. When it does open $ORACLE_HOME/webcache/webcache.xml and find the line âHOSTNAME=package_nameâ and change it to âHOSTNAME=hostnameâ. Retry the configuration step after making the change and your install should proceed and complete successfully.
Web cache does not like packages. You should have multiple copies of webcache.xml â one for each host in the package (webcache.host.xml) â with the corresponding hostname in each file. As part of the package startup webcache.host.xml should be copied as webcache.xml before "opmnctl startall".
Given Oracleâs direction and attitude, these solutions will be short lived. They want you to use RAC and Application Server HA instead of Service Guard.

Data Guard Test cases

Hi All we are in process of implementing Data Guard (Physical Standby) setup. Everything has been done. Now we need some good test cases to test our setup. Can you please provide some inputs in testing this.

Simple test would be to create few test tables with some data in primary and see if they are applied in your DR site by Data Guard.
In terms of testing failover & failback or Switchover and Switch back you would need to go through oracle documents or refer the following link.

Configuring Data Guard on 2 different instance in same machine

Hi All,
I am new to the Data Guard concept. I am using Oracle 10g (Release 10.2.0.1.0) in Windows 7 environment . I have created 2 database instance its running fine.
For testing purpose, Is it possible to implement Data Guard concept between 2 instance in the same machine? whether it will impact any problem?
Thanks & Regards
Sami.

You would use the same one. That is, you would not have a separate tnsnames.ora and listener.ora.
What I was trying to say is you still need to add the SID_LIST_LISTENER lines that Data Guard uses
Example
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.uservices.umn.edu)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0)
(sid_name = PRIMARY)
TNS Example
STANDBY =
(DESCRIPTION =
(SDU=32767)
(SEND_BUF_SIZE=2092500)
(RECV_BUF_SIZE=2092500)
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = HOSTNAME)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = STANDBY)
