How to open a "manual" Physical standby database in read/write mode

Hi,
I am running Oracle Database 10g Release 10.2.0.3.0 - 64bit Production Standard Edition on Linux version 2.6.9-42.0.8.ELsmp ([email protected]) (gcc version 3.4.6 20060404 (Red Hat 3.4.6-3))
I've created a physical standby database, but since I am running Standard Edition, I am not using the DataGuard features. I use the rsync utility to copy over the archivelogs to the standby database, and I apply them periodically to the standby database.
The standby database is started this way :
startup nomount pfile='/u01/oradata/orcl/initorcl.stdby';
alter database mount standby database;
Everything runs perfectly fine, I can do "alter database open read only" and then I can do selects into tables to confirm that everything is up to date.
The thing is, if I shutdown immediate the database, then do just startup :
shutdown immediate;
startup;
The database opens with no error messages, but is still in read-only mode...
I read that the default behavior for a standby database is to open read-only, like I am experiencing, but I would like to know what is the right way to open it correctly in read-write mode (I understand that after that, my standby will not be standby anymore and that I will have to recreate my standby database).
Thanks,
Mat

Hello,
There're features which allows you to open a Standby database in Read/Write mode but for all I know
it needs Entreprise Edition.
In Enterprise Edition you can use Logical Standby database. More over, for Physical standby there's
a way by using flashback database so as to rolling backward the database and avoiding to recreate
the Standby.
In Standard Edition I'm afraid that you'll have to recreate your Standby database.
Best regards,
Jean-Valentin

How to check data in physical standby database?

Hi!
I'm maintaining physical standby database system. everyday, i must check tranfer and apply progress. I known, it operate very good. No archive gap is found.
But i want to check data in physical standby database that there is consistant with primary database, there isn't? What method do I use? How to do?
thankS

I hope the following will help
Verifying the Physical Standby Database
==========================================
Once you create the physical standby database and set up log transport services, you may want verify that database modifications are being successfully shipped from the primary database to the standby database.
To see the new archived redo logs that were received on the standby database, you should first identify the existing archived redo logs on the standby database, archive a few logs on the primary database, and then check the standby database again. The following steps show how to perform these tasks.
Step 1 Identify the existing archived redo logs.
On the standby database, query the V$ARCHIVED_LOG view to identify existing archived redo logs. For example:
SQL> SELECT SEQUENCE#, FIRST_TIME, NEXT_TIME
2 FROM V$ARCHIVED_LOG ORDER BY SEQUENCE#;
SEQUENCE# FIRST_TIME NEXT_TIME
8 11-JUL-02 17:50:45 11-JUL-02 17:50:53
9 11-JUL-02 17:50:53 11-JUL-02 17:50:58
10 11-JUL-02 17:50:58 11-JUL-02 17:51:03
3 rows selected.
Step 2 Archiving the current log.
On the primary database, archive the current log using the following SQL statement:
SQL> ALTER SYSTEM ARCHIVE LOG CURRENT;
Step 3 Verify that the new archived redo log was received.
On the standby database, query the V$ARCHIVED_LOG view to verify the redo log was received:
SQL> SELECT SEQUENCE#, FIRST_TIME, NEXT_TIME
2> FROM V$ARCHIVED_LOG ORDER BY SEQUENCE#;
SEQUENCE# FIRST_TIME NEXT_TIME
8 11-JUL-02 17:50:45 11-JUL-02 17:50:53
9 11-JUL-02 17:50:53 11-JUL-02 17:50:58
10 11-JUL-02 17:50:58 11-JUL-02 17:51:03
11 11-JUL-02 17:51:03 11-JUL-02 18:34:11
4 rows selected.
The logs are now available for log apply services to apply redo data to the standby database.
Step 4 Verify that the new archived redo log was applied.
On the standby database, query the V$ARCHIVED_LOG view to verify the archived redo log was applied.
SQL> SELECT SEQUENCE#,APPLIED FROM V$ARCHIVED_LOG
2 ORDER BY SEQUENCE#;
SEQUENCE# APP
8 YES
9 YES
10 YES
11 YES
4 rows selected.

How to identify that my physical standby database in use real time apply?

Hi,
Can any one give me the SQL to identifiy that my physical standby database is in real time applying redo logs?
Its urgen please....
Thanks.

You could just look at the alert log. Look for "Recovery of Online Redo Log"
Or you could select from v$standby_apply_snapshot to see if the standby is up-to-date.
select thread#, to_char(snapshot_time,'dd-mon-yyyy:hh24:mi'),
to_char(applied_time,'dd-mon-yyyy:hh24:mi'),
to_char(newest_time,'dd-mon-yyyy:hh24:mi') from V$STANDBY_APPLY_SNAPSHOT;

How to stop and cancel physical standby database (ORACLE 10g)

Dear All,
I have physical standby setup and I want stopped for the time being that to use the database as an normal DB (standalone inestance).
Kindly advise and show me how do I do that.
Regards,

executing below query on primary db stops log shipping to standby.......i think this is sufficient for disabling your physical standby setup temporary
alter system set log_archive_dest_state_2=defer scope=both;
In future if you want your dataguard setup back..............you can rebuild the standby and enable the log_archive_dest_state_2 parameter.

Opening a Standby Database in Read-Only mode

Is there anyway to open a Standby database up to date as of a certain time? I'm currently using the 2 commands to get close to the time required.
ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT;
ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL;
Such as, similar to this? RECOVER DATABASE UNTIL TIME '2012-01-25:15:00:00';
We're on 11.1.0.7, which I'm currently very unhappy with.
Thanks for any help, as my google-fu hasn't worked today.

Maybe
I did a quick test :
8:42 open the databases and start recovery
8:43 check status from primary
Shows sequence 75
and "TO STANDBY" for switchover status
Did log switches at 8:44, 8:45, and 8:46
8:50
SQL> alter database recover managed standby database cancel;
SQL> RECOVER STANDBY DATABASE UNTIL TIME ' 2012-01-25:20:43:00';
Media recovery complete.
SQL>
8:52
SQL> alter database recover managed standby database disconnect from session;
Database altered.
Check status
TO STANDBY and sequence 78Still need to check alert logs and do another log switch. It checks out so the quick test works.
However the quick test is incomplete since there was no before and after data in the test and the time period was very short.
Andy may be right, but I would test, test test. ( if you do please let us know the results )
Thanks Andy!
Best Regards
mseberg
Later
After sleeping on this I decided my first thought is probably correct. You cannot go back in time and still be in sync. While the test statement did not error or produce any alert log entries, it probably did nothing. Oracle is smart enough to know you cannot have your Cake and eat it too.

Hi,
I have an ORA-05178 (data block corrupted) about a standby database which in read-only mode. About production database, there is no problem.
After analyze, this is an index segment :
SELECT segment_name , segment_type , owner , tablespace_name

WHERE file_id = 58
AND 218173 BETWEEN block_id and block_id + blocks -1

How to open a view to a Item in "read only" mode directly from SAP Logon.

Hello Gurus;
We need to display a given portfolio item to the user in display (read only) mode.
We have managed to open a view to the portfolio item using function INM_UI_NAV_GET_OIF_URL to obtain its URL and FM CALL_BROWSER to open it. The problem is that the item is opened in edit mode.
Is there any way to open this item in read only mode (and disable the 'Edit' button as well)?
Thanks in advance.

Please, anybody can solve this?

Backups on Physical standby database?

I am using dataguard and a physical standby database.How to assign backups on physical standby database to reduce the load on Primary database.
environment: windows
Database version:11.2.0.1.0
What are the pro and cons on assigning RMAN backups jobs to physical standby database?

Is it better to assign the RMAN backups on standby?i am using the RMAN catalog.Yes, Already mentioned to reduce contention on primary. You can register even standby.
Do i need to change the setting to backup archive logs from standby database? If i won't backup the archive logs on Primary the FRA will be full and i can't access it ?You can include even archive logs with your database backup.
How to assign the archive logs backups,full backup on standby database?Same script will work, Before that cancel MRP and after backup start MRP. That should be fine.
Recently i tested backup from standby and restore, Please see below log.

Flashback database and Physical Standby databases

Hi,
We are thinking about the following scenario in our Production Standby databases. We are trying to do this to avoid number database cloning situations.
When we require live data to test data fixes :-
1. Switchover/failover the standby database.
2. opened this database in read write mode.
3. Apply the fix and test.
4. Flashing back the database prior to the SCN which did the switchover/failover.
5. Activate the standby again using a new standby controlfile.
Would you experts please comment on this idea?
Is this is possible? If so, would you please guide through the steps/some documentation.
Thanks in advance

This will not work according to me,
1)U can give previous SCN in rollback and gets the data till that SCN, but it will not become standby unless u make it a standby again manually by creating standy controlfile etc(may be this will be succesfull and limited up to check the data fixes).
2)Iif your first step succesfull then what about the fixes u test by applying patches using opatch and patchsets that cannot be rollbacked using flashback because they are copying new version files and adding some more configuration files to oracle home?.
There are lots of pitfalls and loop holes needed to be checked

How to change the database character set on physical standby database?

Hi,
We have a database with character set WE8ISO8859P1 and migrated the character set to WE8MSWIN1252 using csscan/csalter scripts. This database has a physical standby database setup also and after the migration, the physical standby database is still showing the character set as WE8ISO8859P1. How can I change the characterset on the physical standby? I raised a Service Request with Oracle, and they said that recreating the standby database is the only supported way of changing the char set on the standby database. Is this true?
Thanks,
Sreekanth

How to make a physical standby database in the read_only state in 11g?

In 10g, we can make a physical standby database in the read_only state. But in 11g, no a read_only state for a physical standby database. How to make a physical standby database in the read_only state in 11g?

Hi
read-only mode (for 11g physical standby)
A mode in which a database can be opened that allows queries, but disallows modifications.
A physical standby database can be opened read-only so that queries may be performed. If a license for the Oracle Active Data Guard option has been purchased, a physical satndby database can be open while redo apply is active. This capability is known as Real-time Query.

Does anyone know how to convert logical standby database(10.2.0.3) to Physical Standby Database(10.2.0.3)? Is this possible? If so,please give me steps for it.
Thanks.
Regards,
RJ.

I don't believe this to be possible. One of the steps invloved in the creation of a logical standby is the following:
ALTER DATABASE OPEN RESETLOGS;
This makes the logical standby a different incarnation of the db from the primary.
A physical standby is a binary copy of a primary db, a logical standby is a completely seperate db that just happens to get sql statements applied to it that are generated from a primary db, but is open read/write.
One avenue, though would be if you had flashback database enabled and you flashed back all the way to when the db was a physical standby and then rolled forward with the archived redo logs.
It's somewhat unlikely you are in that situation, but that is a possibility.
Indeed the 11g snapshot standby does this sort of thing:

Error while trying to open physical standby database - (DATA GUARD)

Hi Everyone,
I have problems in opening the database of the physical standby in read- write mode/ read only mode. I have a primary server which is running on 2 node RAC and the standby on a seperate single server being used as DR. I recently got this server and my aim was to isolate the standby server from primary server and perform few test. As it has never been tested even once.
Primary Database spec: (2 Node Rac on ASM)
Oracle Version : 10.2.0.3.0
O/s : HP-UX B.11.23
Standby Database spec: (Single Node)
Oracle Version : 10.2.0.3.0
O/s: HP-UX db01 B.11.23
Error:
alter database recover managed standby database cancel;
Database altered.
SQL> alter database open
2 ;
alter database open
ERROR at line 1:
ORA-16004: backup database requires recovery
ORA-01152: file 1 was not restored from a sufficiently old backup
ORA-01110: data file 1: '+DATA/dprod/datafile/system01.dbf'
Parameters :

FOR=(ONLINELOGFILES,PRIMARY_
ROLE) DB_UNIQUE_NAME=PROD
remote_archive_enable string true
fal_client string DPROD
fal_server string PROD1, PROD2
Steps tried so far:
Changed log_archive_dest_2 = DEFER on both the primary nodes
Standby :
startup nomount
alter database mount standby database;
alter database recover managed standby database disconnect;
alter database recover managed standby database cancel;
alter database open/readonly (tried both)
Same error.

Additional Information :
There is a delay of 20 minutes before the logs get applied. which has been intentional set by team.
Any help will be highly appreciated. Thanks in advance
