Can we run application services when physical stand by database is in read

can we run application services when physical stand by database is in read only mode
i Want to up the EBS application services and check login when phyiscal standby database is in read only mode.
Is it possible? for checking dataguard database application as well.

but i just want to know that can i start EBS application services and nagivate the application.Without distrubing my primary database and application.You should not do as the moment you open the standby database it becomes invalid.
Thanks,

Adding Temp tablespace to physical stand by database?

I am getting the below error when i try to load data using SQL loader from physical stand by database to another database after making the physical stand by database in read only mode.
ORA-25153: Temporary Tablespace is Empty.
On primary database when i query
SQL>select ts#,name from v$tablespace;
TS# NAME
2 TEMP
On physical stand by when i query
SQL>select ts#,name from v$tablespace;
TS# NAME
2 TEMP
On primary DB when i query
select name from v$tempfile where ts#=2;
NAME
/dev/vx/rdsk/oradata/tempfile0101
On standby when i query
SQL>select name from v$tempfile where ts#=2;
no rows selected
At this point do i need to add datafile to the TEMP tablespace of stand by database or just need to add TEMP tablespace to stand by database.?
DB version:9.2.0.6
Thank You all...

Can you make sure that /dev/vx/rdsk/oradata/tempfile0101 is copied to standby site during the standby creation. Often it happens that the hot backups are copied to standby ste and generally they dont contain temp files. If the files is present , then i'll suggest you to do a quick bounce of standby instance to make sure that controlfile attempted to access it. You can also try recreating the standby control file on promary and copy it to standby site along with the tempfile and start the instance with new control file.
If you want to add temp files to the standby instance, the only option you have is to add them on primary site. If you have standby_file_management as auto they will get copied over. If not you can copy the files to standby instance and restart the recovery.
Please let us know if any of the hints are applicable to your case.

Stand by database

Hi guys,
OS: Windows Server 2003 (32 bit)
DB Version: 10.2.0.3
Question:
Simple question I guess but still I'm failing to understand the logic. Will the changes applied on the primary database also occur in the stand-by, for instance if I delete a table in the primary database, will that also take effect in the stand-by database?
Regards,
Durbanite

Have you had a log switch to create a new archived redo log in that time?? the change will only be transported across to the standby when it gets writted to an archived redo log that is then sent to the standby and applied (if using physical standby)
If not, in sqlplus, do : alter system switch logfile+; and watch it get sent to the standby and then check the if the table is still there or not.
HTH,
Ric.

Open stand by database to run scripts

hello all,
I am having one physical stand by database which is synchronized with production database.Now i am have some scripts which extracts data.But i want to run this scripts on stand by database which is in recovery mode.Now i want to make the stand by database in read only mode and after executing the scripts make it back to stand by database in recovery mode.My plan to make the stand by database is as follows.
SQL>connect / as sysdba
SQL>recover managed standby database cancel;
SQL>alter database open;
Now i want to make it back to physical standby database and my plan is as below.
SQL>connect / as sysdba
SQL>shutdown immediate;
SQL>alter database mount standby database;
SQL>recover managed standby database disconnect;
Will the above scripts run for my purpose.I don't have a test server to test it.
DB version:9.2.0.6
Thank You All...

First off, I would say that not having a test environment to test this sort of thing is exceptionally short-sighted. If the database is important enough to go through the effort of setting up a physical standby, it is well worth having a proper test environment so that you can test scripts before applying it to production.
Second, you will want to review the documentation for [opening a physical standby database for read-only access|http://download.oracle.com/docs/cd/B10501_01/server.920/a96653/manage_ps.htm#1014483] which walks through a different set of steps than you have outlined here. I wouldn't dream of running the documented script on a production environment, though, without having first run it in some sort of test environment.

Manually Apply Archived log to stand by database

Hi all,
I'm using Oracle 10g. So, we need to apply the archived logs of Primary database to stand by database, but this process must be manually.
A "robot" copy the archived logs to destination. I need to get these archived logs from destination and manually apply to stand by database.
How can I do this?
thank you very much!!!!

How can I do this?First stop current recover process as
alter database recover managed standby database cancel;Then transfer all need archive logs from primary to standby side and apply these manually using below command.
recover standby database until cancel
/*this command will ask full path of archive logs
and give these then finally enter "CANCEL" word*/Finally you can continue normal/automatic state using
alter database recover managed standby database ;

Redolog operation from primary to stand by database

We have primary and stand by database and our primary database is generating too much redo logs. what I learnt is reading of redlogs from primary is sequential operation. Basically this operation is taking more time. So is there any way to parallel the process of reading of redo logs from primary database.
Or I want a confirmation from oracle experts that this cant be done.

Hi,
The process has to be serial from log to log as later events may be dependant on earlier events.
For an individual log increasing the value of recovery_parallelism from it's default of 0 may help in your standby.
Cheers,
Harry

How to apply missing arching logs in a logical stand by database

hi,
I have created logical stand by data base for our production.It was working fine.We have not set the value for standby_archvie_dest and it send the archive files to $ORACLE_HOME/dbs, due to high volume transavtion many files generated and $ORACLE_HOME mount got filled and logical stan by apply stopped working and Db went down as well.
I tried to apply the files once i bought back the instance but after applying one archivie file it stopped applying further.
and logical stand by not working appropriately.
Please let me know that is there is a mechanism to apply the missing logs?
DB version : 10.2.0.5
OS :OEL 5

Creating a Stand By DataBase for Production

Hi,
One more question How to do create a Standy Database for the Production
Database.
Can one tell the procedure to create a Standy By database ??
Thanks,
Pavan Kumar

That's documented in the Data Guard Concepts and Administration manual. Chapters 3 & 4 cover creating physical and logical standby databases.
http://download.oracle.com/docs/cd/B19306_01/server.102/b14239/partpage1.htm
Of course, since you didn't mention what version of Oracle you're using, I picked the 10.2 documentation to link to. You can find other manuals online at http://tahiti.oracle.com if you're using a different version.

Stand by database is slow

Hi all,
I am testing data guard at my laptop with winxp, i m using Oracle 9.2 version.
Data guard is implemented and working fine.
The problem i am facing is very slow response from standby database, it takes so much time while startup, change recovery mode and changing read only mode. Where as primary database is working fine.
Any idea what could be the reason.
Regards,
Asim

couple of days earlier i implement data guard on the same laptop, at that time primary and standby database was working fine no performance (slow) issues, then i need to reinstall windows, now when i once again configured data guard and face the stated (standby slow) problem.
I have tested some hit and trials and finally stop all other database basis and started only standby in nomount mode but same problem.
:-) I agree with your point, this is a not a normal behaviour.
Further i think to solve this problem, i might reinstall windows, probably then this problem will be solved and some one new might arise.

Hi
I want to create Primary (new database) from my standby database by using RMAN. kindly tell me how this is possible.

Never done it. The document covers it : (assumes failover )

I know this is not what you asked for however its worth a look too:
