How to sync the standby database with the primary?
Hi..We have dataguard setup for our production databases(10.2.0.3).
I need one clarification regarding the standby database sync with primary.We identified one of our databases is not in sync with the primary and for longtime the archives are not getting applied at the secondary.
We decided to take the incremental (from SCN)backup from primary and use that at the standby to resolve the gap as described in the book "Oracle dataguard concepts and administration".
But, before doing that,we observed couple of structural changes were not applied at the standby(ex:some tablespaces were not created in secondary where as they were there in primary).
How to apply these changes at the secondary as the standby is in mount state.(Can I open this database and create those tablespaces ?? or do you suggest any other way.
Thanks for your reply.
This points to a setup problem. Something missing, a parameter set wrong etc.
While your question is asking something different - How to correct, I would consider how to prevent. Unless you have a gap or logs not applied you have a deeper issue.
If you have a gap or logs not applied then correct it and check to see if the missing object are present.
The key parameters for Oracle 10 are :
FAL_SERVER=STANDBY
FAL_CLIENT=PRIMARY
STANDBY_FILE_MANAGEMENT=AUTO
DB_FILE_NAME_CONVERT='STANDBY','PRIMARY'
LOG_FILE_NAME_CONVERT='STANDBY','PRIMARY'
log_archive_dest_1='LOCATION=/u01/app/oracle/oradata/PRIMARY/archive VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=PRIMARY'
log_archive_dest_2='SERVICE=STANDBY LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=STANDBY'
LOG_ARCHIVE_DEST_STATE_1=ENABLE
LOG_ARCHIVE_DEST_STATE_2=ENABLE
LOG_ARCHIVE_MAX_PROCESSES=30
Check them on both sides for issues.
If your standby is really trashed consider using RMAN to duplicate it. You might end up saving time. I have Oracle 11 short notes on this but it will work on Oracle 10 too.
http://www.visi.com/~mseberg/duprman.html
Otherwise use statements like this to resolve you gap.
ALTER DATABASE REGISTER LOGFILE '/u01/app/oracle/oradata/STANDBY/archive/PRIMARY_1_20_716110538.arc';
ALTER DATABASE REGISTER LOGFILE '/u01/app/oracle/oradata/STANDBY/archive/PRIMARY_1_21_716110538.arc';See Section 5.8 Managing Archive Gaps of oracle document B14239-05

Creating a Standby Database with the Same Directory Structure
Hello gurus,
I am self-learning the feature Oracle Data Guard, so I am testing it on Oracle 10g R2.
At Oracle documentation there is a section F.4.: Creating a Standby Database with the Same Directory Structure*, that explains how to create a standby database with RMAN but there is something that I don´t understand:
In the standby server, I created a database with the SID equal to production database* with the objetive to have the same directory structure, but when I try to startup nomount the standby database with pfile appear this expected error:
ORA-16187: LOG_ARCHIVE_CONFIG contains duplicate, conflicting or invalid attributes
So my question is: Is possible have the Same Directory Structure on both: Production and StandBy server?
Thanks in advanced.Uwe and mseberg: thanks for your quick answers
I have a doubt: How can you have the same directory structure if you have differents SIDs?, for example if you follow the OFA suggestions you would must have:
On Production server: */u01/app/oracle/oradata/PRIMARY/system.dbf*
On StandBy server: */u01/app/oracle/oradata/STANDBY/system.dbf*
Or you created the directory structure manually on StandBy server? For example replacing the string STANDBY* to PRIMARY* before create the database using dbca.
Do you understand my doubt? Excuse me for my english.
Thanks. -
This question is in Business Continuity Plan (BCP)
if the production database is down, how to switch to standby database using the replication environment in ASEAssuming you're referring to Sybase's Replication Server (repserver) product ...
Repserver moves data changes from one database to another.
Repserver can't 'switch' your application to use a different database; something outside of repserver has to do the actual switching.
If your application happens to be connecting to your ASE via Sybase's OpenSwitch (or similar) product, then OpenSwitch would be responsible for switching your application to use the standby database. Whether you have OpenSwitch perform the switch automatically, or via a manual command, is up to your BCP requirements.
If your application connects directly to ASE then you'll have to decide how/when to get your application to switch to the standby database. In the simplest form this would require shutting down the application, making sure replication is quiesced (ie, all in-flight transactions have been applied to the standby database), modify the interfaces/sql.ini file (used by your application) to point to the standby database, make any customized changes to the standby dataserver/database (eg, unlock application logins, take databases out of 'dbo use only' mode, etc), and startup the application (at this point it should connect to the standby database per the changes to the interfaces/sql.ini file). -

Should the STANDBY database be in NOMOUNT Mode?
Hi There,
Just setup DataGuard and want to monitor the primary and standby databases via the grid. However, I can not configure the standby database because the standby database is in NOMOUNT mode. Was I suppose to mount it? If not, how do I configure the standby database with the enterprise manager in NOMOUNT.
Thanks.
JJennifer;
Yes the standby should be in MOUNT mode before apply starts. Or No, to NOMOUNT if you prefer.

Problem with the standby database?
i am working on 10gr2 on rhel4.
i am creating a standby database on the same servr machine.
i have taken a cold backup of the primary database and edited the parameter files for the primary as well as the standby database.
the only problem is that i am unable to open the standby database in the read only mode. following is the problem:
SQL> alter database open read only;
alter database open read only
ERROR at line 1:

thanksif i issue this command on the primary database, i get
SQL> select status, error from v$archive_Dest where dest_id=2;

what is the reason, my logs are not propagating to the standby.
also some entries from the primary alert log file is as below:

How to monitor the successful archive log shipment to the standby database
Hello,
From the primary database, which data dictionary do I view to get information whether the standby database has received and processed the archive logs from the primary database. Both databases are 11202 on linux. Another question, which views on the primary database contain a flag sent by the standby database to the primary database to let the primary database knows that the standby database is up and functional? My purpose is to query the primary database for infomation that tell me the standby database is alive and functioning. I want to only query the primary database for these information about the standby database. Thank you in advance.watson2011 wrote:

Hi Everybody,
Today in my test db,
I switched the standby database to physical primary database,
it is sucedded.But after that when i go to make its original state means i want my current standby (ie original primary) as a primary,
i got error that flashback feature is not on .Then how can i do this.
Regards
Hemantthen for test ,
in primary i issue--shut immediate
in standby database --altetr database recover managed standby database cancel;
alter database recover managed standby database finish;
alter database commit to switchover to primary;
alter database open;
NOW I CHK THAT THE PRIMARY DB IS WORKING FINE.You performed Fail over , You can get back your standby(current-primary).
If you create a restore point(with flashback enabled) then only you can able to restore to that particular point..
Since you have not configured, You have no option.
*Restore Points in Oracle10g Release2 [ID 330535.1]*
THEN AFTER 15 MINTS ,
I WANT THE ORIGINAL STATE,HO W CAN I DO THIS,FLASHBACK FEATUE IS NOT ON.Now its not possible. -
Add a new datafile to the standby database
Hi,
i have a standby database in recovery managed mode.
Now i must add a new datafile on the production database and i would like
to know how i realized adding the new datafile on the stanby database.
is it right when i do the follow steps?
Before i add a datafile to the primary database,
cancel the recovery on the standby database.
-> add the new datafile on the primary database
after all archived redo logs have been applied, cancel managed recovery:
alter database recover managed standby database cancel;
startup nomount
alter database mount standby database;than
ALTER DATABASE CREATE DATAFILE '/oracle/DB1/db1_9/data9' as '/oracle/DB1/db1_9/data9';
alter database recover managed standby database disconnect;Thanks8.4.1.1 Adding a Tablespace and a Datafile When STANDBY_FILE_MANAGEMENT Is Set to AUTO
The following example shows the steps required to add a new datafile to the primary and standby databases when the STANDBY_FILE_MANAGEMENT initialization parameter is set to AUTO.
Add a new tablespace to the primary database:
SQL> CREATE TABLESPACE new_ts DATAFILE 't_db2.dbf'
2> SIZE 1m AUTOEXTEND ON MAXSIZE UNLIMITED;
Archive the current redo log so it will get copied to the standby database:
SQL> ALTER SYSTEM ARCHIVE LOG CURRENT;
Verify that the new datafile was added to the primary database:
SQL> SELECT NAME FROM V$DATAFILE;
NAME
/disk1/oracle/dbs/t_db1.dbf
/disk1/oracle/dbs/t_db2.dbf
Verify that the new datafile was added to the standby database:
SQL> SELECT NAME FROM V$DATAFILE;
NAME
/disk1/oracle/dbs/s2t_db1.dbf
/disk1/oracle/dbs/s2t_db2.dbf
8.4.1.2 Adding a Tablespace and a Datafile When STANDBY_FILE_MANAGEMENT Is Set to MANUAL
The following example shows the steps required to add a new datafile to the primary and standby database when the STANDBY_FILE_MANAGEMENT initialization parameter is set to MANUAL. You must set the STANDBY_FILE_MANAGEMENT initialization parameter to MANUAL when the standby datafiles reside on raw devices.
Add a new tablespace to the primary database:
SQL> CREATE TABLESPACE new_ts DATAFILE 't_db2.dbf'
2> SIZE 1m AUTOEXTEND ON MAXSIZE UNLIMITED;
Verify that the new datafile was added to the primary database:
SQL> SELECT NAME FROM V$DATAFILE;
NAME
/disk1/oracle/dbs/t_db1.dbf
/disk1/oracle/dbs/t_db2.dbf
Perform the following steps to copy the tablespace to a remote standby location:
Place the new tablespace offline:
SQL> ALTER TABLESPACE new_ts OFFLINE;
Copy the new tablespace to a local temporary location using an operating system utility copy command. Copying the files to a temporary location will reduce the amount of time that the tablespace must remain offline. The following example copies the tablespace using the UNIX cp command:
% cp t_db2.dbf s2t_db2.dbf
Place the new tablespace back online:
SQL> ALTER TABLESPACE new_ts ONLINE;
Copy the local copy of the tablespace to a remote standby location using an operating system utility command. The following example uses the UNIX rcp command:
%rcp s2t_db2.dbf standby_location
Archive the current redo log on the primary database so it will get copied to the standby database:
SQL> ALTER SYSTEM ARCHIVE LOG CURRENT;
Use the following query to make sure that managed recovery is running. If the MRP or MRP0 process is returned, managed recovery is being performed.
SQL> SELECT PROCESS, STATUS FROM V$MANAGED_STANDBY;
Verify that the datafile was added to the standby database after the redo log was applied to the standby database.
SQL> SELECT NAME FROM V$DATAFILE;

Standby Database with Standard Edition
Hi All,
I'm attempting to setup a Standby database with Oracle 10g Standard Edition. I must manually copy over the archive logs to my Standby database server because i'm using Standard Edition.
Once my primary database archive logs have been copied over to the standby location shouldn't the database automatically apply those archive logs? I have issued the "alter database recover managed standby database disconnect from session" so my understanding is that it is in recovery mode and shoudl be finding the archive logs to apply. Can anyone confirm that this configuration should work with Standard Edition and perhaps point me in the right direction, which parameters in the init file to check, to get my standby database to apply these archive logs automatically.
Thanks,To quickly determine the level of synchronization for the standby database, issue the following query on the physical standby database:
SQL> SELECT ARCHIVED_THREAD#, ARCHIVED_SEQ#, APPLIED_THREAD#, APPLIED_SEQ#
2> FROM V$ARCHIVE_DEST_STATUS;
ARCHIVED_THREAD# ARCHIVED_SEQ# APPLIED_THREAD# APPLIED_SEQ#
