How to apply the changes in logical standby database

Hi,
I am new to Dataguard. I am now using 10.2.0.3 and followed the steps from Oracle Data Guard Concepts and Administration Guide to setup a logical standby database.
When I insert a record to a table from the primary database side, when i query the same table from the logical standby database, it doesn't show the new records.
Did I miss something? What I want to do is when I insert a record in the primary db, then the corresponding record will be inserted in the standby db.
Or I totally misunderstand what Oracle data guard is? Any help are appreciated.
Denis

Hi
Can anyone help to answer me is my logical standby db have a archive gap?

How to apply archivelog with gap on standby database

Hi All,
Oracle Database version : 9.2.0.6
Following is my sequence of commands on standby database.
SQL>alter database mount standby database;
SQL> RECOVER AUTOMATIC STANDBY DATABASE UNTIL CHANGE n;
ORA-00279: change 809120216 generated at 07/24/2006 09:55:03 needed for thread

ORA-00289: suggestion : D:\ORACLE\ADMIN\TEST\ARCH\TEST001S19921.ARC

O/S-Error: (OS 2) The system cannot find the file specified.
I have check the last sequence# on standby database which is 19921. And I have archivelog starting from sequence# 20672 onwards. When I am trying to apply archive log starting from sequence# 20672 , it is searching for 'D:\ORACLE\ADMIN\TEST\ARCH\TEST001S19921.ARC' file and cancel the recovery. Please note that I don't have those missing archive on Primary server as well. So How can I apply the remaining archive log which I do have from 20672 onwards.
I hope I am not creating any confusion.
Thx in advance.

Hi Aijaz,
Thx for your answer. But my scenario is bit complex. I have checked my standby database status which is not running in recovery mode. I have tried to find archive_gap which is 0 on standby server. I am copying all archived log from primary to standby thru the script every 2 hour and appying them on standby. After applying, the script is removing all applied log files from primary as well as standby. So it is something like I have archivelog from 1,2,3,7,8,9,10. So 4,5 and 6 archivelog are missing which is required when I am trying to recover standby database. Also note that I want to apply 7,8,9,10. I will loose some data from those missing archive but I have cold back any way. I don't have those missing archivelog files(4,5 and 6) anywhere at all. So how can I recover standby database. I am using standby just for the backup purpose.
I hope my question is clear now.
Thx in advance

How to apply Oracle patch when physical standby database in place

Dear All,
I want to apply Oracle patchset 8 on 10.2.0.5 when physical standby database in place. What are the steps for Primary site and for standby site.
Thanks in advance
Kamran Laeeq

Hi Kamran,
You will not upgrade or patch the standby database by importing offline redologs. On the contrary, there is a procedure to do this. Please note that you will not transitiate the role from standby to primary or startup the database. You will just startup the database by executing "startup mount" and "startup upgrade", during the upgrade. It means that you will not change database role standby to primary and you will be able to continue to the log shipment after the respective upgrade.
But, it is very important that you should stop the log shipment and apply all the offline redologs, before the upgrade. Technically, you can import offline redologs after the upgrade, by changing "compatibility" parameter in oracle, but regarding to my experiences it may cause some problems after you transitiate the role from standby to primary.
In short;
In order to stop log shipment, at the primary site;
alter system set log_archive_dest_state_2=defer;
In order to import all the offline redologs without a delay, at the standby site;
alter database recover managed standby database cancel;
alter database recover managed standby database nodelay disconnect from session;
I hope that I clarified the issue,
Best regards,

Creation of Logical Standby Database Using RMAN ACTIVE DATABASE COMMAND

Hi All,
I am in confusion how to create logical standby database from primary database using rman active database command.
What i did:-
Create primary database on machine 1 on RHEL 5 with Oracle 11gR2
Create standby database on machine 2 on RHEL 5 With Oracle 11gR2 from primary using RMAN active database command
Trying to create logical standby database on machine 3 on RHEL 5 with Oracle 11gR2 using RMAN active database command from primary.
The point which confuse me is to start the logical standby in nomount mode on machine 3 with which pfile like i create the pfile for standby database do i need to create the pfile for logical standby db.
I done the creation of logical standby database by converting physical standby to logical standby database
I am following the below mentioned doc for the same:
Creating a physical and a logical standby database in a DR environment | Chen Guang&#039;s Blog
Kindly guide me how to work over the same or please provide me the steps of the same.
Thanks in advance.

Thanks for your reply
I already started the logical standby database with pfile in nomount mode. And successfully completed the duplication of database. by mentioning the DB_FILE_NAME_CONVERT and LOG_FILE_NAME_CONVERT parameter.
But i am not able to receive the logs on the above mentioned blog i run the sql command to check the logs but getting "no rows selected"

How to delete the foreign archivelogs in a Logical Standby database

How do I remove the foreign archive logs that are being sent to my logical standby database. I have files in the FRA of ASM going back weeks ago. I thought RMAN would delete them.
I am doing hot backups of the databases to FRA for both databases. Using ASM, FRA, in a Data Guard environment.
I am not backing up anything to tape yet.
The ASM FRA foreign_archivelog directory on the logical standby FRA keeps growing and nothing is get deleted when
I run the following command every day.
delete expired backup;
delete noprompt force obsolete;
Primary database RMAN settings (Not all of them)
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 9 DAYS;
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE DB_UNIQUE_NAME 'WMRTPRD' CONNECT IDENTIFIER 'WMRTPRD_CWY';
CONFIGURE DB_UNIQUE_NAME 'WMRTPRD2' CONNECT IDENTIFIER 'WMRTPRD2_CWY';
CONFIGURE DB_UNIQUE_NAME 'WMRTPRD3' CONNECT IDENTIFIER 'WMRTPRD3_DG';
CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON ALL STANDBY;
Logical standby database RMAN setting (not all of them)
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 9 DAYS;
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; # default
How do I cleanup/delete the old ASM foreign_archivelog files?

OK, the default is TRUE which is what it is now
from DBA_LOGSTDBY_PARAMETERS
LOG_AUTO_DELETE TRUE SYSTEM YES
I am not talking about deleting the Archive logs files for the Logical database that it is creating, but the Standby archive log files being sent to the Logical Database after they have been applied.
They are in the alert log as follows under RFS LogMiner: Registered logfile

How to monitor SQL Apply for 10.2.0.3 logical standby database

We have a logical standby database setup for reporting purposes. Users want to monitor whether sql apply is working or failed closely as it has reporting repercations.
In case of 9i databases , there was "Data Not Applied (logs)" metric which we used for alerting and paging, in case a backlog of more than 5 log files developed.
With 10.2.0.3 onwards, the metric no more exists.
I would like to learn from other, how to monitor the setup, so that if the backlog in logs shipping or applying develops, we get page.
Regards.

regather the statistics on the table with method_opt=>for all columns or for all indexed columns or whatever size 1
The 'size 1' directive will remove the histogram statistics.
Sorry, didn't read ur post in a hurry. Below article (http://www.freelists.org/post/oracle-l/Any-quick-way-to-remove-histograms,13) removes histogram without re-analyzing the table. Hope that helps!!!

but with only 1 bucket (i.e. no histograms).You might try the attached script, that reads the stats using
dbms_stats.get_column_stats and re-sets them, minus the histogram,
using dbms_stats.set_column_stats.
I haven't fully tested it - it's only 10 minutes old, even if Ihave
slightly modified for you another script I've used for quite some
time - and the spool on 10.2.0.3 seems to confirmthat the histogram
is, indeed, removed, while all the other statistics are preserved.I
have also reset density to 1/num_distinct, that is the value youget
if no histogram is collected.regards,

Slow SQL Apply on Logical Standby Database in Oracle10g

Hi,
We are using Oracle 10g Logical Standby database in our production farm but whenever there is bulk data load (5-6 GB data) on the primary database, the logical standby seems to be hung. It takes days to apply the 5-6 GB data on the logical standby.
Can anybody give me some pointers how can I make my SQL Apply fast on the logical standby for bulk data.
Thanks
Amit

Hi there,
I've a similar problem. I did an insert of 700k on a table. It takes me over 1 1/2 hours to see the data. Notice, I increased the "max_sga" to 300m and "max_servers" to 25" and didn't help the performance at all.
My version is 10.2.0.3 with the patch 6081550.

Apply Patches on Oracle Database with Logical Standby Database

Here I am:
I got a primary database with a logical standby database running Oracle 11g. I got two client applications, one is the production site pointing to the primary one, another one is just a backup site pointing to the logical one.Things will only be written into the primary database every mid night and client applications can only query the database but not add, update nor delete.And now, I want to apply the latest patch on both of my databases. I am also the DNS administrator, I can make the name server pointing to the backup site instead of the production one.I want to firstly apply the patch on the logical one, and then the physical one.
I found some reference which explains how to apply patches by adopting "Rolling Upgrade Method". however, I want to avoid doing any "switch over" mentioned in the reference because I can make use of name server. Can I just apply patches as the following way?
1)Stop SQL apply
2)Apply patches on logical standby database
3)let the name server point to the backup site
4)Apply patches on the primary database
5)Start SQL apply
6)Let the name server point back to the production site
Thanks in advance.

How to run automated maintenance task on a logical standby database ?

Hi
I realize that i do not see any job runs for automated maintenance tasks on my logical standby database.
Which are the conditions that must be fulfilled for automated maintenance tasks to run?
Thanks
Christoph

Hi,
In an Oracle Data Guard environment, the Scheduler includes additional support for two database roles: primary and logical standby. You can configure a job to run only when the database is in the primary role or only when the database is in the logical standby role. To do so, you set the database_role attribute. This example explains how to enable a job to run in both database roles. The method used is to create two copies of the job and assign a different database_role attribute to each.
By default, a job runs when the database is in the role that it was in when the job was created. You can run the same job in both roles using the following steps:
Copy the job
Enable the new job
Change the database_role attribute of the new job to the required role
The example starts by creating a job called primary_job on the primary database. It then makes a copy of this job and sets its database_role attribute to 'LOGICAL STANDBY'. If the primary database then becomes a logical standby, the job continues to run according to its schedule.
More Information please cheek below link:
Examples of Using the Scheduler
Thank you

How to convert logical standby database to Physical Standby Database

Hi,
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:

How to skip DELETE command on logical standby?

IBM AIX 5.3
Oracle DB version 10.2.0.3
Can I skip just delete or update on the standy instead of all DML's on particular object using dbms_logstdby.skip,
e.g this will skip all DMLs on the test object.
exec dbms_logstdby.skip(statement => 'DML',schema_name => 'SCOTT', object_name => 'TEST');
Can I use 'DELETE' as a statement type in dbms_logstdby.skip to just skip delete on object.
exec dbms_logstdby.skip(statement => 'DELETE',schema_name => 'SCOTT', object_name => 'TEST');

You can not skip all deletions on a particular table with a statement such as this....
You can use SKIP_TRANSACTION to skip a transaction or even multiple transactions but the Oracle documentation states:
is an inherently dangerous operation. Do not invoke this procedure unless you have examined the transaction in question through the V$LOGMNR_CONTENTS view and have taken compensating actions at the logical standby database.
SKIP_TRANSACTION Procedure
Specifies transactions that should not be applied on the logical standby database. Be careful in using this procedure, because not applying specific transactions may cause data corruption at the logical standby database.

Changing the archive destination in standby database?

My DB is running on Oracle 9.2.0.6.0. I have data guard for my primary database.
Now i wanted to change the archive destination only standby database. What is the process? Any response or any link is appreicated. Thanks

The standby database wouldn't generate archivelogs until and unless it is opened (eg in a failover). So, although there is a definition for the log archive destination in the standby's init.ora / spfile, it is used only to read archivelogs shipped from the primary.
If you are talking of the destination that the primary's archivelogs are shipped to on the standby, technically once the archivelogs are applied on the standby, they are not required and can be deleted. You would be able to configure this.

Real-time apply cascaded logical standby database

Hi
I have a primary database orcl
Pysical standby database orcl_std
Cascaded logical standby database orcl_tri which receives archivelogs from orcl_std
Real time apply is enabled both in orcl_std (physical standby) and orcl_tri (logical standby)
When I create a table in primary orcl, I am unable to see it on orcl_tri (Although real time apply is enabled)
However, when I switch log in primary, I can see the new table on orcl_tri.
My question is, why realtime apply is not working in my scenerio ?
orcl_std : ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION USING CURRENT LOGFILE;
orcl_tri: ALTER DATABASE START LOGICAL STANDBY APPLY IMMEDIATE;
Oracle 11.2.0.3.0

Hi mseberg,
Thanks for your reply.
There is no load or network issue as I`ve just created these databases for the experiement.
I have the same output from standby and primary databases.
