Dataguard 11g

Hi ,
Oracle 11g claims heteogeneous dataguard supporting physical / logical standby on heterogenoeus OS platforms.
Can I , for instance create a primary database ( oracle 11g enterprise edition) on AIX and a
primary physical or logical standby on HP-UX ?
Thanks

As long as the "endianness" of both operating systems is the same, yes this is possible.
I don't have the OS' running here for confirmation.

How to know the delay in redo log apply on Active Dataguard 11g

Hello All,
How to know the delay in redo log apply on Active Dataguard 11g...
Do we need to wait till log switch occurs?
Or is it recommended to schedule a log switch every 15 min, no matter data is updated/inserted or not in primary?
Please suggest...

What is the redo transport service you are using? is it LGWR or ARCH ?
Output of query select * from v$parameter where name like 'log_archive_dest_2' shows below value...

So is it lgwr already configured...? if yes then how do i see the delay in both servers..
Yes, the network is good as they both resides in same LAN within same rack

Oracle Spatial Datatypes and Dataguard 11g

Hi
Does anyone know if the following datatypes are supported in dataguard 11g for logical standby or physical standby?
SDO_Geometry
SDO_georaster
thanks
sunir

A correction. Logical standby (SQL Apply) doesn't currently natively support spatial data types but sdo_geometry can be supported thru EDS by creating a logging table and two triggers and some manual work. Please check it out from My Oracle Support:
Note 559353.1 - Extended Datatype Support (EDS) for SQL Apply. "Extended Datatype Support (EDS) is the ability for SQL Apply to extend support for additional datatypes that are not natively supported yet by SQL Apply. EDS relies on a new capability in Oracle Database 10g Release 2 Patch Set 3 (10.2.0.4) and Oracle Database 11g Release 1 Patch Set 1 (11.1.0.7) that allows triggers to fire on the logical standby database. "

Oracle Active Dataguard 11g - Passwords

Hi all
Environment description: Production database, 11.2.0.3 version, standalone running on Solaris and an Oracle Active Dataguard database in read only mode, same version and operating system.
Question: The users passwords and sys/system passwrod (orapw ) could be different in the ADG environment? I mean, could the orapwd file and user password be changed in the Dataguard database ?
Thanks a lot.

Active dataguard is option after configuring dataguard.
You can put standby database in Open(read only) mode also you can enable Recover(MRP) while open so this can be used for reporting purpose too.
Please refer below links for configuring them.

Dataguard 11g setup between AIX and Linux

Hi,
We are planning to move our Oracle databases from AIX 6.1 to Oracle Linux 6.2
To reduce the downtime, we are thinking of setting up a dataguard (physical or logical) and do the switchover.
Have you performed this before?
Will you pls send me the steps?
Thanks,
DR

Hello again;
I thinking no for the same reason.
When my shop moved from AIX to Linux we just install Oracle on Linux and patched it to the same level as the AIX. We created users, tablespaces, job etc in advance and then just used import/export to move the needed schema's. Data Pump make this much easier.
Do a schema(s) compare and switch when ready. But in any event I don't believe Data Guard can help you. You mostly have a migrate issue.
Please consider closing your question when complete.

Post switch over in oracle dataguard 11g

Dear Guru,
Switch over has been completed successfully from primary database to standby database.
new primaray database is open and accessible but its showing his satus in v$database as below.
database_role = primary
switchover_status = not allowed
db_unique_name = dg1_stdby
old primaray database which is now standby showing his satus in v$database as below.
database_role = physical standby
switchover_status = session active
db_unique_name = dg1_primy
when check status in data guard broker its
for both the databases - dg1_primy and dg1_stdby its showing error ORA-16810: multiple errors or warnings detected for the database.
when checked dataguard log file on new primary server its showing
ORA-16816: incorrect database role
ORA-16700: the standby database has diverged from the primary database
Please guide me how to resolved issue.
Thanks & Regards,
Nikunj Thaker

Hi Nikunj,
You can find the scenario, in the "Problem : Data Guard Broker Switchover fails With ORA-16665 using Active Data Guard", on metalink.oracle.com
First of all manually complete the Switchover, ie. restart the Databases in its new Role. Note that the final Role Change has not been recognized by the Broker, so you have to rebuild the Data Guard Broker Configuration when the Databases have been restarted:
DGMGRL> remove configuration;
DGMGRL> create configuration ...
DGMGRL> add database ...
DGMGRL> enable configuration;

DataGuard 10gr2 (10.2.0.4) AIX 5.2-primary Aix 6.1-Standby possible?

We currently have 10.2.0.4 DG configuration running on three AIX 5.2 servers (one primary, two standbys). We will be installing some new servers that will be pre-loaded with AIX 6.1. If we were to install 10.2.0.4 on these new AIX 6.1 servers is it possible to create additonal standbys on them? Or is there a limitation in 10gR2 Datagurad that the OS versions must be exactly the same?
Doc ID: 413484.1 indicates that this is possible but I am unclear if this only applies to DataGuard 11g?
Thanks in advance. It would also be appreciated if anyone knows of an Oracle document that definitively states whether this can or cannot be done.

Whilst I've only done AIX upgrades at the level like 5.2 to 5.3 etc using standbys, there is no reason that a major OS release level shouldn't function correctly. As long as both run the same DB software patch level (10.2.0.4 as you've stated) then it should be fine. If you're really paranoid raise an SR with Metalink and get it in writing.

Database shutdowns in Maximum Protection mode

Hi,
I am using oracle dataguard 11g(11.2.0.1.0) on OEL5. My dataguard is working fine in MAXIMUM PERFORMANCE mode. But when i try to put my database mode in MAXIMUM PROTECTION MODE my database gets shutdown.What could be the possible reason for this????
Regards,
007

Hello;
Quote "To ensure that data loss cannot occur, the primary database will shut down, rather than continue processing transactions, if it cannot write its redo stream to at least one synchronized standby database"
Section - 1.4 Data Guard Protection Modes - Data Guard Concepts and Administration 11g Release 2 (11.2) E10700-02
From section 5.1 of the same document ( Maximum Protection )
"Oracle recommends that a minimum of two standby databases be used to
protect a primary database that runs in maximum protection mode to prevent a single
standby database failure from causing the primary database to shut down."

Truncate Tables

Is it possible to truncate tables or table partitions in a physical standby database using dataguard.
The reason behind this is we do not need to carry forward data into the standby more than a certain period. The table is more of a datawarehouse table.
Is this possible on dataguard 11g R1.
Thanks,

Hi,
aprarently this is not possible. A physical data guard configuration is marked by the fact that primary and standby database are bitwise identical (spreaking from the data files here).
So it is not possible - even in 11g. In 11g you can open the standby database, modify data and flashback the database to the point you started modifying the standby and continue apply
the redo log data.
If you want a solution: You can use streams to replicate the data to another database. In this "another" database you are free to truncate the data. Or you can use
a logical standby database where you can truncate the table as well.

DataGuard on Oracle 9i and Oracle 11g

Hi Guys,
Is it possible to configure DataGuard between an Oracle 9i primary database and an 11g standby?
Thanks for the help.
Carlos

See this MAA paper - http://www.oracle.com/technetwork/database/features/availability/maa-wp-10gr2-rollingupgradebestprac-1-132006.pdf which explains a rolling upgrade using a Data Guard standby. The caveat is that you will have to create a 10.2.0.4 physical standby on the new hardware and convert it to a Logical Standby before upgrading it to 11.2. So you will have to have both homes on the new hardware. So your database has to be able to support a Logical standby.
Also, depending on the hardware change the combination has to be a supported one as detailed in the MOS note " Data Guard Support for Heterogeneous Primary and Physical Standbys in Same Data Guard Configuration" [ID 413484.1]
Going from a single instance to a RAC is no problem.
Thanks.

Concept about Query Scn in Dataguard in Oracle 11g

What are the details concepts behind the’ query scn’ in Dataguard in Oracle 11g. I read the concept from Oracle Datagaurd 11g Handbook but it was not clear for me.

It's the highest SCN to which data is synchronised between the primary and secondary in a way that the secondary guaranteed read-consistent. It's therefore not possible to query an active standby for data modified after that SCN. At any given time, there might be transactions committed on the primary but not yet shipped or applied to the standby. You're not allowed to see those on the secondary. Not sure how much more detailed you want to get, really.

11g to 10g Dataguard

Dear Friend,
We have set up for Physical stand by between two 10g instances.
Now its required to upgrade oracle version , but 1st we want to upgrade Primary DB version to 11g then later on stand by.
So is 11g to 10g DG is possible?, does logical standby support this? if yest then what will be process for same.

So is 11g to 10g DG is possible?nope, it would not make sense. a standby is for failover, how can you failover to an older release?
if you want a reporting system on an old release - ok (I wouldn't agree with you but whatever). You would do that using streams.
