RMAN in active data guard with real time apply ON without a catalog DB

I would like to know whether I can take RMAN backups (both level 0 & incremental) in active data guard with real time apply ON without a catalog database. version is 11.2.0.3.2. Will it make difference in the control file of standby syncing with primary? Can I use these backups on primary to restore and recover the database(including control file backup)?

Thank you very much msberg. Could you please answer the below queries as well?
Should I cancel Real Time Apply before starting RMAN?
Will it make difference in the control file of standby syncing with primary? Is it possible to use these backups on primary to restore and recover the database(including control file backup)? If possible, how will I do that?

Goldengate from physical standby with Active data guard or from logical standby - which is better?

Hi,
We have Oracle 11.2.0.4 and are currently using Active Data Guard on a physical standby. My boss wants me to use Goldengate
to replicate several schema from Oracle to SqlSserver. She doesn't want to touch the Primary, which is in production. Would it be better
to setup a Logical standby for Goldendate to use, in addition to the Physical standby? Or will it be sufficient to use the Physical standby?
The application tables don't all have primary keys. I'm trying to decide if the Logical standby adds another layer of complexity or would
introduce delays in getting the data from Oracle to Sqlserver.
Thanks in advance,

Hi,
In this case I recommend you to use physical standby + Golden gate with ALO mode. You might have sligthly more trouble in logical standby. it means you might have more trouble at Goldengate's extract side.
You said
The application tables don't all have primary keys.
so you have to add keycols on replicat side.
I recommend you to add an index which should consist of keycols columns. it will be necessary for replicat performance.
Best Regards

Active data Guard but with delay on applying redo logs

Hello,
A question: Active Data Guard gives the possibility of having a physical stand-by database open read-only, for instance for making 'up-to-date' reports.
Data Guard also has the possibility to apply logs with delay, for instance with a delay of some hours. Every commit on primary database is applied to standby after the delay period.
Can this delay be combined with Active Data Guard? This means that standby database is open read-only but with the delay... In case the delay is 2 hours, every report created on standby is ("up-to-date" minus 2 hours)...
Thanks for your answer,
Jan.

Hello All,
I answered my own question: indeed it is possible to activate 'real time apply' but with a delay in applying the logs. In EM-11 check the box "enable real time query" and apply. Nect go to thje tab "standby role properties" and change the value after "Apply delay" to for instance 30 minutes. Apply also.
Log on on the primary, create a table, insert some rows and do some logswitches. Log in on the standby and check for the new table. Notice that after 30 minutes the switched logs are applied, even when you change the delay period within the 30 minutes. The information about the delay seems to be in the log, since it is possible to change the delay immediately after the logswitches to 3 minutes, drop the table and do some logswitches again. The logs with the 'create table' statement in it are NOT applied after 3 minutes, but still after 30 minutes. The drop of the table however is done after 3 minutes on the standby. So the 'delay' information is in the log sent over to the Stand-by!

Using Oracle EM 11g with Active Data Guard 11g

Has anyone installed Active Data Guard 11g with OEM 11g for an active-active state or know if there are any installation procedures with these two products? We will be installing these products this year. Thanks, Cathy

If you already have both servers configured in Grid Control as targets, it should be fairly easy to create a standby database on server B. OEM has Availability tab on your primary database Instance section should have "Data Guard" section which has "Setup and Manage" option. You follow through the wizard, and it will generate a standby database on server B. Then you can convert your standby db on server B to Active Read-only database by clicking few more buttons.
If you do not have these two servers configured on your Grid Control, that would be the first task.
We set up three standby databases using Grid Control 11g in our test boxes, and they worked very well. Our biggest problem was to actually installing the Grid Control, but once installed, everything was easy.

Oracle E-Business Suite and Active data guard

Hi,
I'm looking to setup current E-business Suite R12.1.3 application without any down time. I've Primary Data Center and Secondary Data Center. I would like to setup seamless failover to another secondary data center in case of 1st data center failure.
Can be this achieved by using Active Data guard? If not what would be best solution? In case of active data guard can I failover site to secondary data center and apply patches on primary site?
I want to acheive 100% availability of application. Any suggestions are welcome!
Thanks

Need suggestion on Active data guard or Logical Stand by

Hi All,
Need a suggestion of on below scenario.
We have a production database ( oracle version 11g R2 ) and planning to have a Logical standby or physical standy (Active data guard). Our usage of the standby database is below.
1) Planning to run online reports (100+) 24x7. So might create additional indexes,materialized views etc.
2) daily data feed ( around 300+ data files ) to data warehouse. daily night, jobs will be scheduled to extract data and send to warehouse. Might need additional tables for jobs usage.
Please suggest which one is good.
Regards,
vara.

Hello,
In active dataguad Whig is feature from 11gRx ,
If you choose active dataguard, you have couple of good options, one is you can make a high availability of your production database, which can act as image copy of production, as you are asking in 11g you have more advantage where you can open in read only mode and at the sometime MRP will be active, so you can redirect users to connect standby to perform select operations for reporting purpose. So that you can control much load on production ,
Even uou can perform switchover in case of role change, perform failover if your primary is completely lost. Also you can convert to physical to logical standby databases & you can configure FSFO
You have plenty of options with active dataguard.

consider closing the thread if answered and keep the forum clean.

What are the pros and cons using Active Data Guard vs Data Guard?

My understanding is that Active Data Guard is an additional database option for Oracle 11gR2 Enterprise Edition. I need to know the pros and cons using Active Data Guard vs Data Guard in order to decide whether to get pay extra for the Active Data Guard.
Thanks for any help.

Before jumping in to Active Data Guard, one needs to evaluate :
a. Is there really a need to run queries on the Standby ? The Standby could / should be at a remote site so queries are "across the network". Depending on the nature of the queries and the volume of output, the "performance" of the queries may not seem to be the same.
b. If the database is not in Maximum Protection mode, the data "seen" at the standby may not be in "real-time" synch
c. Not all applications are truely read-only when querying. Some applications use "jobs" that write to tables when querying. Such would not work with Active DataGuard. (example : EBusiness Suite). There are very complicated ways of handling this -- and one needs to consider if the complications can be introduced and supported.
Over the network accessing standby read only is really not an good idea, I think no one will compare performance with primary and standby,
But some of them they want to validate data which are very critical, as it is matching with primary or not, Its an added advantage with ACTIVE DATAGUARD
Prior to that until unless stop MRP, open database and then we need to validate, So there is an interruption of recovery, I can say its also an advantage where there is no interruption of recovery.

DB link problem between active Data Guard and report application database

My database version in 11.2.0.2.0 and OS is Oracle Solaris 10 9/10.
I am facing a problem in my Active data guard Database for reporting purpose. Active Data guard information is as below.
SQL> select name, database_role, open_mode from v$database;
NAME DATABASE_ROLE OPEN_MODE
ORCL PHYSICAL STANDBY READ ONLY WITH APPLY
Problem detail is below
I have created a db link (Name: DATADB_LINK) between active data guard and report application database for reporting purpose.
SQL> create database link DATADB_LINK connect to HR identified by hr using 'DRFUNPD';
Database link created.
But when I run a query using db link from my report application database I got this below error.
ORA-01555: snapshot too old: rollback segment number 10 with name "_SYSSMU10_4261549777$" too small
ORA-02063: preceding line from DATADB_LINK
Then I check Active Data Guard database alart log file and get below error
ORA-01555 caused by SQL statement below (SQL ID: 11yj3pucjguc8, Query Duration=1 sec, SCN: 0x0000.07c708c3):SELECT "A2"."BUSINESS_TRANSACTION_REFERENCE","A2"."BUSINESS_TRANSACTION_CODE",MAX(CASE "A1"."TRANS_DATA_KEY" WHEN 'feature' THEN "A1"."TRANS_DATA_VALUE" END ),MAX(CASE "A1"."TRANS_DATA_KEY" WHEN 'otherFeature' THEN "A1"."TRANS_DATA_VALUE" END )
But the interesting point if I run the report query directly in Active Data Guard database, I never got error.
So is it a problem of DB link between active Data Guard and other database?

Active data guard - patching

Hi Gurus,
I have primary db amsprd and active data guard amsprd_stby.
we are planning to apply application patches in amsprd. earlier we used to rely on rman backup for restore in case of any failures.
I would like to make use of standby as primary and keep the business up immediately after application patch failures.(to reduce the downtime - application failures are not having any rollback steps :-( - vendor product).
to achieve this,
before application patch application
do i have to just stop the log shipping?
or do i have to stop just log file apply?
what are the steps involved in case of primary applicaiton patching failures.
Thank you.

So the Application Patch may turn out as a "Logical Mistake" from the Database perspective.
One option would be to stop the Apply on the Standby Database. If your Application Patch was no good, you could do an "Immediate Failover" which will open the Standby immediately without applying the received redo first like an ordinary Failover would. You would have to create a new Standby Database on your Ex Primary site then.
Another option would be to turn on Flashback Logging on both sites. If your Application Patch was ok - nothing to do. If not, flashback both sites to before the App Patch. Look here for an example:
http://uhesse.wordpress.com/oracle-database-ha-architecture/2010/08/06/using-flashback-in-a-data-guard-environment/
Second option has the benefit that you do not delay an emergency failover, should your Primary incidentally get destroyed during the App Patch. Also, if you need to rewind the Logical Mistake, you do not need to recreate the Standby completely. If you are on 11gR2, you can even turn on/off Flashback Logging without having to restart:

Active Data Guard License is technical or legal ?

Dear friends
I have seen in many documents , that the Active Data Guard needs additional license , but one of my friends said that he could implement Active Data Guard without any licenses ( he only downloaded the Enterprise edition of database 11g r2 ).
my question : is the active data guard license , a technical license or legal license ?

If you have a server that has an Oracle EE database on it, you need to license it. It doesn't matter if only a standby database is on the server - DataGuard is just a feature like other features. One server with a primary + one server with the standby = 2 servers you need to pay licenses for.
Everyone else, relax, answer the question, and stop waving your Big Swinging Audit Team language. The original poster demonstrates how widely misunderstood Oracle licensing is among DBAs - which given how often it's changed, is not a surprise ;-)

Active Data Guard and Undo and ora-01555

Hi
We have an 11.1.0.7 two-node RAC primary with a single instance Active Data Guard physical standby. When running a datapump export from the standby, we get an ORA-01555 although the undo_retention is set way beyond the run time for the export.
I'm looking to better understand undo within the context of Active Data Guard. Is there any dependency for undo between the primary(s) and standby? Are the undo settings (undo_retention, undo tablespace size..) on the primary and standby independent of each other?
Thanks.

The standby is a Physical Standby. An exact copy of the Primary. The undo at the standby is controlled by the redo coming from the Primary. When the undo gets overwritten at the Primary it gets overwritten at the standby regardless of what is running there. You can't have undo kept around longer at the standby, it is an EXACT copy of the Primary.
Increasing the undo tablespace and the undo_retention at the Primary will allow more undo to be kept at both the Primary and the Standby but the standby is still controlled by the Primary's management of the undo. Of course you should change the parameter at the standby too so that everything behaves the same when you make the standby a Primary database.
Hope this helps.
Larry
