Asynchronous CDC on a Logical Standby database (10gR2)

Hi,
Question:
Is it possible to setup Asynchronous CDC on a Logical Standby database (10gR2)?
Background:
In our Oracle Data Warehouse environment where we need to provide up-to-the-second "operational" reporting against a Logical Standby database (10gR2 Data Guard) as the production application database owners do not permit direct reporting against the Primary database (10gR2); we also have a Data Warehouse database (10gR2) that requires more sophisticated/summary reporting which is updated at less regular intervals from the Logical Standby database.
The complication is that although the Logical Standby database will serve the purpose of a 'syncronized' version of the Primary database by giving us a current-state view of the data, we require more detailed change data capture on certain tables to audit change history between the points we extract data for the Data Warehouse.
The DBAs do not want to set-up Asynchronous CDC on the Primary database, so is it possible to setup Asynchronous CDC on a Logical Standby database?
Anyone done it before?
Any issues?
Any alternatives?
Any help would be much appreciated.
Thanks

As far as I know it is but it would be easier, and more robust, to just create a second logical standby and feed them both from the primary.
Logical Data Guard and Streams are essentially just two implementations of the same technology written by the same team of developers.

Autolog CDC could be one possible solution. It uses a feature of the downstream capture.

Is CDC feature working on the logical standby database

I would like to implement CDC on the standby logical database instead of primary production database. Is CDC working on the logical standby database??
Thanks.

Thanks. My database version is: 10.2.0.4.0 and no plan to upgrade to 11g.
Either asyn or syn CDC on logical standby database is ok for me. I searched but couldn't find any docs for how to set CDC for logical standby, they are all for primary database.
Please help.

Log mining is taking too much time in logical standby database

dear DBAs,
today i found a gap between the production database and the logical standby database and i found that the log mining is taking more than 1 hour to complete an archivelog (size: 500M)
note that the MAX_SGA is 1500M and the MAX_SERVERS=45
the databases is 10gR2 (10.2.0.5.0) running on a linux machine RHEL 4
please your help.
thx in advance

Problem building logical standby database

Hi all,
i am trying to build a logical standby database on platform Sun OS 10/Oracle 10gR2. I am following the Oracle document http://download.oracle.com/docs/cd/B19306_01/server.102/b14239/create_ls.htm#BEIGHEIA
I have created a physical standby database and converting it to a logical standby database. I ensured that my physical Standby is in Sync with primary.
Procedure DBMS_LOGSTDBY.BUILD executes successfully on primary.
The problem is that the command *'alter database recover to logical standby test;'* DOESN'T END. No error in archive log. I have identified the archived redo log that contains the LogMiner dictionary and the starting SCN and applied that archive log on standby. Still the the above command doesn't end.
Any Help is appreciated.

SQL> alter database recover to logical standby m2test;
This command doesn't return an sql> prompt. Alert log says it is waiting for log sequence 25. The command is running is for more than 5 hours, but still not competed.
Alertlog:
Thu Feb 5 22:14:25 2009
alter database recover to logical standby m2test

Document says :-
If a dictionary build is not successfully performed on the primary database, this command will never complete.
But the dictionary build on primary is successful.
SQL> execute dbms_logstdby.build;
PL/SQL procedure successfully completed.
I used the following queries and to find which archive log contains dictionary build and made sure that the log archive sequence 22 is applied on standby.

Create table on Logical Standby Database

Dear DBAs,
here is my situation;
1. My primary database (where the tables' owner is "ICC" having a DBA) is used for insert/update transactions.
2. The logical stdby DB (dataguard structure with MAX availability) is used to generate reports, after updating some tables owned by the same user "ICC". note that these tables are excluded from the replication.
3. The developers might need to create this kind of tables to generate another kind of reports.
The issue is that when the standby apply is enabled or disabled, the user ICC is not able to create a new table, it gives ORA-01031: insufficient privileges. note that it's not practical to ask the DBA to disable the "APPLY" at any table creation.
Do you have an idea about how to resolve.
My database is 10gR2 path.10.2.0.4.0 on Windows 2003
Thank you in advance

If you stop applying log on the logical standby you can easily create a table over there. See oracle docs. The following list shows >how to re-create a table and restart SQL Apply on that table:
>
Stop SQL Apply:
SQL> ALTER DATABASE STOP LOGICAL STANDBY APPLY;
Ensure no operations are being skipped for the table in question by querying the DBA_LOGSTDBY_SKIP view:
SQL> SELECT * FROM DBA_LOGSTDBY_SKIP;
ERROR STATEMENT_OPT OWNER NAME PROC
N SCHEMA_DDL HR EMPLOYEES
N DML HR EMPLOYEES
N SCHEMA_DDL OE TEST_ORDER
N DML OE TEST_ORDER
Because you already have skip rules associated with the table that you want to re-create on the logical standby >database, you must first delete those rules. You can accomplish that by calling the DBMS_LOGSTDBY.UNSKIP >procedure. For example:
SQL> EXECUTE DBMS_LOGSTDBY.UNSKIP(stmt => 'DML', -
schema_name => 'HR', - object_name => 'EMPLOYEES');SQL> EXECUTE DBMS_LOGSTDBY.UNSKIP(stmt >=> 'SCHEMA_DDL', -
schema_name => 'HR', - object_name => 'EMPLOYEES');
Re-create the table HR.EMPLOYEES with all its data in the logical standby database by using the >DBMS_LOGSTDBY.INSTANTIATE_TABLE procedure. For example:
SQL> EXECUTE DBMS_LOGSTDBY.INSTANTIATE_TABLE(shema_name => 'HR', -
object-_name => 'EMPLOYEES', -
dblink => 'BOSTON');
Start SQL Apply:
SQL> ALTER DATABASE START LOGICAL STANDBY APPLY IMMEDIATE;Regards.

Creating a new schema in a Logical Standby Database

Hi All,
I am experimenting with logical standby databases for the purpose of reporting, and have not been able to create a new schema in the logical standby database - one of the key features of logical standbys.
I have setup primary and logical standby databases, and they seem to be running just fine - changes are moved from the primary to the standby and queries on the standby seem to run ok.
However, If I try to create a new schema on the logical standby, that does not exist on the primary, I get "ORA-01031: insufficient privileges" errors when I try to create new objects.
Show below are the steps I have taken to create the new schema on the logical standby. Any help would be greatly appreciated.

Logical Standby Database in NOARCHIVE Mode

Hi,
I have configured a Logical Standby Database for Reporting purposes. A Physical Standby Database is running for MAA. i.e. in case of Role Transition (switch/Failover) the Physical Stdby Db will get the role of the Primary.
The logical standby database is creating a lot of Archive Redologs files, nearly every minute. Redolog files are 50MB and there is no work done in db during the time. I'm NOT using Standby Redolog files.
Is there a need for logical standby database to be in NOARCHIVELOG mode? The Primary is definatley in ARCHIVELOG mode.
Thanks for any responses.
regards
Sahba

hi,
well there are two things to the above:-
1. there was an archive file nearly every minute:
this is due to a db recovery. for some reason, the db was in inconsistent state, after a sudden shutdownof the OS. I was on a test environment, on windows vista, unfortunately. unimportant ... a reboot solved it.
2. Logical standby db in NOARCHIVE MODE when setup for the purpose of Reporting.
As long as the MAA configured for the primary db, such as physical standby db, and a second, the logical standby db setup purely for the purpose of reporting, which then can run with NOARCHIVELOG mode, after converting the physical standby db to logical.
logical standby db uses Streams architecture, so this method brings cost, time and performance advantages to the customer.

Sahba

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

Creating logical standby database

Hi all,
10.2.0.1
Following this link
http://download.oracle.com/docs/cd/B19306_01/server.102/b14239/create_ls.htm
Where do i need to issue these statements:
SQL> EXECUTE DBMS_LOGSTDBY.BUILD;
SQL> ALTER DATABASE RECOVER TO LOGICAL STANDBY db_name;
on physical standby or primary database.
I issued the first stament on primary and second on physical standby .
IN the alert log of standby,i have the following entries.
Wed Jan 20 15:34:28 2010
Converting standby mount to primary mount.
Wed Jan 20 15:34:28 2010
ACTIVATE STANDBY: Complete - Database mounted as primary (treasury)
*** DBNEWID utility started ***
DBID will be changed from 306589979 to new DBID of 330710340 for database
.........................I am trying to create a logical standby database after creating a physical standby database.
It seems standby changed to primary which was not desired.
Thanks

Not tried myself, but you might want to have a look at this URL.
It appears to suggest that you need to change names of datafiles as well as value db_name explcitly on standby.

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"

Logical Standby Database and XMLDB

I couldn't find a proper group to post this message and thought I would try here.
I want to set up a Logical Standby Database for our production database server 9.2.0.4.0 with XMLDB. I am having problem with some system tables that were created when I registered some XML schemas.
These tables are in the standby database but Oracle complains the object does not exist.
Any idea?

>
The "may be" is because I have tested flashback of a physical standby to before resetlogs, but not a logical standby.
>
A physical standby keeps the DBID of the primary - a logical standby does not. That is exactly the problem that restricts the reconversion into physical from logical, and you did not encounter that problem.
>
I haven't used "keep identity" but from what I read it relates to "convert to physical" not "flashback database".
>
Exactly. And that is what the OP wants to do: convert to physical (from logical).
You mentioned that this might be possible with flashback.
Problem: During the conversion from physical to logical, the DBID gets changed unless you specify (in 11g) KEEP IDENTITY. This would make it possible to reconvert into phyiscal from logical.
In short: If there is no solution for the changed DBID of the logical standby in order to flashback it into physical as you suggested, then it is not possible .
When I saw your first answer, I thought that you might have a solution in mind in order to solve that obvious problem. Sorry for having bothered you.
Kind regards

Logical Standby databases

Hi,
When we say "Logical Standby Databases are logically identical to primary databases although the physical organization and structure of the data can be different." what does it exactly means?
Does it mean that in logical standby tablespace name, schema name, table name, column names etc can be different and still has the same data as primary?
Does it mean that we can exclude indexes and constraints as present in primary?
Only the data should match with primary word by word, value by value?
I am asking this as i have never worked in a logical standby database but i seriously want to know.
Please answer.
Regards,
SID

Physical standby differs from logical standby:
Physical standby schema matches exactly the source database.
Archived redo logs and FTP'ed directly to the standby database which is always running in "recover" mode. Upon arrival, the archived redo logs are applied directly to the standby database.
Logical standby is different from physical standby:
Logical standby database does not have to match the schema structure of the source database.
Logical standby uses LogMiner techniques to transform the archived redo logs into native DML statements (insert, update, delete). This DML is transported and applied to the standby database.
Logical standby tables can be open for SQL queries (read only), and all other standby tables can be open for updates.
Logical standby database can have additional materialized views and indexes added for faster performance.
Installing Physical standbys offers these benefits:
An identical physical copy of the primary database
Disaster recovery and high availability
High Data protection
Reduction in primary database workload
Performance Faster
Installing Logical standbys offer:
Simultaneous use for reporting, summations and queries
Efficient use of standby hardware resources
Reduction in primary database workload
Some limitations on the use of certain datatypes
