tell me about data guard accommodate with 11g database standard additions or not if no,is there any way to make it working under this edition?one more thing may i have the steps of configuration data guard in real time for anew server.

just realised the data guard configuration seems to be workin but the error kepps appearing on the alert log of both primary and physical standby that i configured. below is my primary and standby pfiles.

I did the all necessary steps required for the physical standby configuration. My standby db is mounted but not able to open.
Below are the steps.

I have this scenario:
- Oracle 11.2.0.3
- RHEL 4.6 64 bits
- Active Data Guard
- Broker configured
- DBconsole configured on primary server
Now, I have server PRIM with the primary database, and server STB with the standby server. For now, the dbconsole is configured in the PRIM server.When I do a switchover (to the standby on STB), EM is not configured, so I use RepManager.sh to clean the sysman user, and I use emca to recreate the dbconsole. After this, everything works.
Once I switch back, the EM is no longer configured on PRIM, so I repeat the previous steps (repManager and emca). Everything is ok after this. I can access the EM on the primary normaly, and this gets information from the broker to provide basic information on the STB (like db status, apply, and so forth).
DB Version- 11.2.0.3
For the maximum protection and maximum availability as well as to enable Real Time Apply we need to setup the standby redo log group. My question is what would be the standby redo log group configuration in case if we setup single instance standby database for 2-Node RAC primary database. Do we require a separate standby redo thread for each primary online redo thread or RFS use the Multiple Standby redo group from the same thread to receive the redo changes from both the node ?
I did standby before and it works wighout any disturbations and even configuration seems to me not very complicated - but it was before. now i am trying to do standby configuration once again. there is database named DESK.
two physical serwers:
sczepl-db07 - primary
r00979 - standby
on each for this serwer there is listener listening on port 1521, and on each is tnsnames configured properly:
for sczepl-db07
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = sczepl-db07)(PORT = 1521))
[code]....
so why primary don't see standby db and claims that ther is no standby service? i proved that there is connection primary <--> standby.
We have a request to configure data guard for databases on the production server. Here is my situation:
We have a backup strategy in place where the backups are being taken on a regular basis. Archive logs are deleted as soon as they are backed up.
My question now is , is there a way of configuring the Data guard in such a way that there would be no change to existing backup strategy (RMAN) and still duplicate the archive logs to another destination and not delete the archive logs by RMAN backup process on that destination while the first destination is deleted.
We will be deleting the logs in the second archive destination using a script which checks if the logs were applied.
I have created dataguard between two instances hosted in two different servers. I have done switchover from primary to standby & then again standby to primary with DGMGRL utility.
1- When I done switchover to primary & trying to open standby database in readonly mode it was giving below error-
ORA-01154: database busy. Open, close, mount, and dismount not allowed now
Why this error was coming ?
2- As I was not able to open standby database in read only mode, I have executed below command-
alter database recover managed standby database disconnect from session;
which return an error as-
ORA-01153: an incompatible media recovery is active
After this I have executed-
alter database recover managed standby database cancel;
which executed successfully.
& then after standby database open in read only mode.
Why above error was coming ?
3- After this I had tried to check the checkpoint_change# & controlfile_change# from primary database and result shows both number were different.
Why they are not matching ?
After switchover the primary is now standby and standby is now primary, the clients are unable to connect to new primary database.

I am having a few issues trying to set up a physical standby database.
The primary database has a different naming structure than the standby and they are at different sites.
Physical is /var/hpsrp/ctrorp03/oradata/u0x/<DB_NAME>/<DB_UNIQUE_NAME> and standby is /var/hpsrp/drforp03/oradata/u0x/<DB_NAME>/<DB_UNIQUE_NAME>.
I have set db_file_name_convert to '<PRIMARY PATH>', '<STANDBY PATH>' times the number of paths as pairs. I have created a blank database for standby and having taken a full backup of primary with control file and standby control file.
Now I hit the issues:
The DB incarnation numbers are different. When I try and do a normal restore e.g. set dbid, restore controlfile; mount; it fails as it is trying to find files in the primary structure and not standby structure. When I try renaming via set newname or auxname it can't find files to restore I guess due to the incarnation id's. If I set the incarnation id and try to restore backup it fails as the incarnation id's don't match.
I have tried looking through various forums and the documentation but can't find a solution, probably can't see the wood for the trees though as there is so much.
Controlling User Access to Tables in a Logical Standby Database can be controlled using the following command:
ALTER DATABASE GUARD STANDBY;
My simple question is: how can I know the current active Guard setting in the standby database?

i have setup the OEM-Dataguard in order to duplicate the DB instance from the primary to the standby DB in the standby server.At first I installed oracle server in Server A (Primary) created DB instance of SCT, in archivelog mode and then I install the oracle binary in Server B (standby) and made 2 servers ORACLE_HOME the same and also I installed OEM agents on the 2 servers and registered successfully to the OEM server.
I then used the dataguard to do the initial backup of the DB in server A and but when I specify the standby DB location, it prompt me the following error.

I new to data guard concept.
I am using oracle 10g with data guard configured , I have primary ( A ) and standby database ( B ) .But because of some unavoidable conditions the primary database ( A ) got shutdown and was not starting , We shifted the standby database ( B ) at new location and changed it to primary with following command ,
startup mount;
alter database recover managed standby database finish;
alter database commit to switchover to physical primary;
shutdown;
startup;
This new primary ( B ) was open for end users for 2 days during which old primary ( A ) was shutdown .
I took the backup of ( B ) and restored it on A AND shutdown the B . Now A is acting as Primary database. Server B is shutdown . I want to change server B to standby database with A running as Primary .Is it possible ?

Why there could sudden spike of demand on UNDO data in Active Data Guard ?
I am working in a bank as an system consultant, i have a SAN Storage Area and oracle as below.
SAN 1
This interface includes the DATA FILES of the oracle tablespace
SAN 2
SAN1 Mirrors the DATA FILES of the oracle tablespace to SAN 2
1. Can i rely on real time data recovery from SAN2 ?
2. if SAN1 (Data Files are currupted) will the SAN2 Data Files will be currupted as well.
3. If the SAN2 is currupted then what Oracle Features can be used to have uncurrupted data.
