Steps to rollback when Logical Standby Database creation fails

Hi,
In case while creating a logical standby database it fails. What steps should be done on primary to rollback the earlier steps. Because while creating logical standby we do certain tasks on primary e.g.
1) create supplemental logging.
2) update init file.
Regards,
Tushar

Hi,
Thanks for the mail. Should I drop the supplemental logging using
"Alter database DROP Supplemental Log data;".
or if we need to disable, how can we do so?
Rest is ok. Anyways I would not be using force logging.
Droping of additional tablespace created to keep logminer tables on primary.
Removing of log_archive_dest_2 information from primary init.
I think the above should do.

Error while Creating a Logical Standby Database

Dears
I setup physical standby db. Now trying to convert it to logical standby db by following this link:
http://download-east.oracle.com/docs/cd/B19306_01/server.102/b14239/create_ls.htm#i92346
When i issue this statement:
ALTER DATABASE RECOVER TO LOGICAL STANDBY orcl2;
I am getting following error:
ORA-00905: missing keyword.
I do not find anything in ALERT.LOG file. The syntax seems to be correct as i carefully copied from the document itself.
Please reply.

Any ideas?

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.

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.

I already have a primary database as well as physical standby database.
What i want to create a logical standby database as well on the same machine where physical standby database is running.
So anyone of you help me out to do that

Creating standby or logical standby database manually?

Hi,
I have to create 4 logical standby databases on a Linux Red Hat 64-bits server.
The primary databases reside on another Linux Red Hat 64-bits server.
The oracle database version is 10.2.0.3.
The question is as follows:
Should I create the logical standby databases manually or should I do it with the Oracle EM Grid Control?
I have read that the creation of standby databases with the Grid Control is very straightforward, but I really want to read of some of your experiences.
I have read that there are some problems in Grid Control with the test of Failover and Switchover.
Please advice.

Hi,
It all depends.
I assume you don't backup your database to tape using RMAN.
Do you backup your database to disk using RMAN?
You would need to set up NFS links from your standby server to the primary server.
For this purpose, in 9i, I made sure my disk backup ended up in <directory>/backup/<nodename>, so I could easily set up a NFS link.
If you do it manually, you need to have made a full database RMAN backup first.
Probably Grid Control is taking care of this for you.
I have done it once using database control in 10g. It is really simple, and you just have to click a few buttons and sit back.
Doing it manually is slightly more work: you need to make sure parameters are correct and you need to write a (generic) script of less than 10 lines.
You probably do have more control over it, though RMAN's duplicate database command is robust and can be restarted easily.
I can't answer your last remark.

Can i convert logical standby database to physical standby database

Dear All,
Can i convert a logical standby database to physical standby database?
If yes, what are the steps to follow?
Thanks
Mahipal

I never needed or tested something like this, but below maybe usefull -
Transient Logical Standby
Users can convert a physical standby to a transient logical standby database to effect a rolling database upgrade, and then revert the standby to its original state as a physical standby database once the upgrade is complete - using the KEEP IDENTITY clause. This benefits physical standby users who wish to execute a rolling database upgrade without investing in redundant storage otherwise needed to create a logical standby database.
http://www.oracle.com/technology/deploy/availability/htdocs/DataGuardOverview.html
But opposite is documented - http://download-west.oracle.com/docs/cd/B19306_01/server.102/b14239/create_ls.htm#BEIGJCAC

Logical standby database

Guys,
Is it possible to create a logical standby database without installing Oracle Data Guard.And if yes how sync. is performed.
Thanks

Hi,
Is it possible to create a logical standby database without installing Oracle Data Guard.In a sense Oracle Streams and Quest Shareplex created a logical standby, but you can have them open too . . . Madhu Tumma explains this in his Oracle Streams book, but it's only conceptually similar to logical standby in Data Guard:
http://www.rampant-books.com/book_2004_2_streams.htm
Hope this helps. . .

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?

Logical standby database issue?

Hi,
I created a logical standby database on the same server as primary database.
then I transited the old primary DB to standby DB,
old standby DB to primary DB.
and "alter system switch logfile" in new Primary DB.
execute sql in new standby DB:
SQL> SELECT APPLIED_SCN, NEWEST_SCN FROM DBA_LOGSTDBY_PROGRESS;
APPLIED_SCN NEWEST_SCN
0
question:
the redo logs can not be applied to new standby DB,
How to solve it?
thanks
DB release:9i

Hi,
Can you upload the output of:
sqlplus> show parameter arc
from both instances, or post the init.ora parameters from both. I would like to verify your arc related parameters.
Also, did you check the alert log in the primary and standby for errors?
Thanks,
Idan.

When i use this command, the SQL Apply starts again but the tablespace is not created on Logical standby database.
kindly give me a solution.
Thanks in advanced.

In Standy database also you need to add TB details for it to recognise Primary DB new TB .
try adding it and retry your operation .

Confusion regarding logical standby database

While designing the logical standby database, Oracle recommends to add the supplement information in the primary database, so that the changed columns are uniquely recorded in redo log file.
In this case the amount of information in redo log files will increase,
So, redo log files will be filled on a faster basis and more archive log will be created, increasing the overhead on background proccess
Should such a trade -off be kept??

I believe Oracle does more than recommend that supplemental logging is enabled. In the Data Guard Concepts and Administration manual
http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96653/create_ls.htm#1071780
"Supplemental logging must be enabled on the primary database before you create the logical standby database."
Yes, this adds to the work that the primary database has to do, but that's the trade-off you get for having a logical standby. If you don't want this extra overhead, you might consider using a physical standby.

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.
