Create logical standby.

Hi.
I've created physical standby database on the same machine.
Standby apply archivelogs.
I strugle with convert physical standby into logical one.
When I try create controlfile for logical get:
SYS@stb>ALTER DATABASE CREATE LOGICAL STANDBY CONTROLFILE AS '/tmp/stbl.ctl';
ALTER DATABASE CREATE LOGICAL STANDBY CONTROLFILE AS '/tmp/stbl.ctl'

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

.........................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.

Imran,
The information from alert log file is not sufficient.
Can you log switch on primary and monitor whether it is archiving in standby or not.
and you can monitor the changes in "v$managed_standby"
Also check for the errors using "v$dataguard_status"
SQL> select error_cdoe, message, timestamp from v$dataguard_status where dest_id=<n>;

Creating logical standby from non primary backup

We want to test creation for logical standby in our test enviroment.
Here is the plan we are
1. Backup Prod.
2. Restore Test Primary (T1) and Restore test standby (T2) from Prod backup.
3. Setup standby between T1 and T2.
Plan is to save the time for backup and restore process. I have not doe it before. Will this process work or T2 restore needs to be done from backup of T1 as that would be primary.

Thanks Tobi.
I will try this. The test system is very large about 16TB and the backup/restore process takes days. I just wanted to be sure if the same backup would work for creating the primary and standby at the same time.
So in this case, I will just have to restore from backup and move forward with archivelogs. Will I have to use the control-file from Prod or from T1.
Use the control file from T1(test primary)
I would like to use the backup COPY.
General steps to follow:
1. restore T1 as the (test)primary DB.
2. recover/apply the T1 using the redo log.
3. restore T2 but do not apply redo to prevent it from divergence from T1. i mean, let T2 scn be behind T1 scn.
4. following the general steps as it apply to you in preparing and creating primary and standby DB
http://docs.oracle.com/cd/B19306_01/server.102/b14239/create_ps.htm
5. make sure T2 can receive and apply redo data from T1
6.covert T2 to logical standby DB

You need to:
- create a SPFILE manually for standby database
- use the RMAN command: DUPLICATE TARGET DATABASE FOR STANDBY
- remove all SPFILE statements from RMAN script.

Create logical standby from existing physical standby on 9i

I have physical standby database 9i running.
I want to try to convert the physical standby to logical standby. i follow the step by step in metalink document no. 748595.1
But I cannot do the 6th step:
6. Issue command to switch physical standby to logical standby after changing db_name in pfile to logical standby name. Shutdown the standby database if mounted and mount the database again. In this configuration, logical standby database name is LGSTDBY.
sql>alter database recover to logical standby LGSTDBY;
alter database recover to logical standby LGSTDBY;
Error at line 1:
ORA-00905: missing keyword
I have tried to create pfile from spfile on stanby and change the db_name to lgstdby.
I started nomount using pfile. I still cannot run the command.
I tried to mount the standby database but error occured:
ORA-01103: database name 'PRIMARY' in controlfile is not 'LGSTDBY'
The document in metalink is for 10.2.0.4
Is it possible to do it at 9i??
Thx for the help...

As long as the OS is the same, it shouldn't matter that one or both are virtualized. I say that with the caveat that (1) MetaLink note 249212.1 states in no uncertain terms that no Oracle product is supported under VMware, and (2) I was told just this afternoon by a member of a development team that it was. I asked if he had documentation to that effect and he said he did and would email it to me when he returned to his office.

I'll ask why we shouldn't ask.

Logical standby and Primary keys

Hi All,
Why primary keys are essential for creating logical standby database? I have created a logical standby database on testing basis without having primary keys on most of the tables and it's working fine. I have not event put my main DB in force logging mode.

I have not event put my main DB in force logging mode. This is because, redo log files or standby redo logfiles transforms into set of sql statements to update logical standby.
Have you done any DML operations with nologging options and do you notice any errors in the alert.log? I just curious to know.
But I wanted to know that, while system tablespace in hot backup mode,In the absence of both a primary key and a nonnull unique constraint/index, all columns of bounded size are logged as part of the UPDATE statement to identify the modified row. In other words, all columns except those with the following types are logged: LONG, LOB, LONG RAW, object type, and collections.

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"

Here are the steps to identify the object in question:
1) Start the replication on logical standby
2) Once the replication starts it will show you the same error in the alert log file as you mentioned above.
3) Query DBA_LOGSTDBY_EVENTS order by EVENT_TIMESTAMP. The last event will capture the name of the object that is creating the problem.
4) Based on your knowledge of database /application objects, you can skip that table using DBMS_LOGSTADBY.SKIP and start the replication again without any issue.
5) If you dont need that object in the logical DB to be replicated then let it be skipped, otherwise reinstate the object again in logical standby.

Logical Standby - Log Apply Error

Hi All
I have configured a 10.2.0.4 logical standby database (single instance) for RAC primary by LOG APPLY process stopped with this error:
ORA-01422: exact fetch returns more than requested number of rows.
Now I did run this command before creating logical standby: EXECUTE DBMS_LOGSTDBY.BUILD;
And I know that there are 80 tables which cannot be uniquely identified, which is fine by business.
Could you someone please tell how can I deal with this problem.
Regards
Amit

Logical Standby Database with 10g+ASM on both sides??

Hi out there,
is there a known way to establish a logical standby database on 10g, if both
sides are running with an ASM setup?
I've tried to create one out of a physical standby database (which is set up
and running w/o any problems), like a book suggested me to do.
The procedure was:
1. switch on supplemental logging
2. prepare initiation parameters (for archive logging etc.) on both sides for
logical stb.
3. shut down the phyiscal standby
4. alter database create logical standby controlfile as '<path>'; on the
primary, transfer the controlfile to the standby db. Here I had to use RMAN
to copy the controlfile into the ASM System, and modify the initfile/spfile
in order to use the controlfile. No problem so far.
5. mount the standby database, alter database recover managed standby database
disconnect; -> At this point, the alert log complained about non-available
datafiles.
6. alter database activate standby database; --> fails ("needs recovery") due
to last point.
The trouble is, the controlfile created at point 4 cointains wrong paths to
the datafiles. Since I can not have the same disk group name on the standby
system, and since ASM renames the stored datafiles by its own, the complaints
of point 5 are comprehensible, but nevertheless annoying.
I tried to backup a controlfile to trace and change the paths, but at after
mounting the standby with this controlfile and proceeding at point 5, the
system says "<path> is not a standby controlfile"
Is there a different way of creating a "Logical Standby Database with 10g+ASM
on both sides"? Metalink said nothing about LogStby and ASM.
Best regards and thanks in advance,
Martin

I'm not sure if this will work but try:
1. create trace control file (you did it)
2. change paths (you did it)
3. recrate control file (you did it)
... there was error occured during mount before
so mount database (not as standby)
4. create standby control file (from recreated control file)
5. shutdown instance, replace control file with new standby control file or replace the control filename in parameter file.
6. mount as standby
What happend?
Update: Tested on my side and it has worked fine... How about you?

Creation of logical standby in 9i from physical standby

Hi all,
I want to create logical standby from physical standby in 9i. can anyone send a doc for this

As per the Oracle documents "You create a logical standby database by first creating a physical standby database and then transitioning it to a logical standby database"
Please take a look at the below URL.
http://download-west.oracle.com/docs/cd/B19306_01/server.102/b14239/create_ls.htm
Regards,
Sabdar Syed.

Create logical standby.
