Standby Data Gurad 10g

Hi!
I'm working on oracle 10g and try to make standby datagurad with same dbname eg. if my primary database name is orcl then my standby database should be orcl with same location because one of mine application is accepting only orcl not standbyorcl.
Could any one help me to make init.ora parameter for primary and standinit.ora for standby with same database name.

You should use an Application Service instead of the standard Database Service in the first place to take care of Role Changes in your Data Guard configuration properly.
Look here for an example:

Hi!
I'm working on oracle 10g and try to make standby datagurad with same dbname eg. if my primary database name is orcl then my standby database should be orcl with same location because one of mine application is accepting only orcl not standbyorcl.
Because when I'm doing switchover to standby database application not able to read standbyorcl and application result through error and close.
Could any one help me to make init.ora parameter for primary and standinit.ora for standby with same database name.

Physical Standby database Oracle 10g Standard Edition

Hello,
I open a new question about testing a standby database a because of this:
I realize that my standby database is 10g Standard and not Enterprise and not 11g.
Because for testing we plan to modify data on Standby, we are looking for some way to restore Standby to the point before testing.
So, I can't use Flashback Recovery Area for restoring my database to a certain point after testing.
In this scenario, the only way that I think is:
On Standby
- Shutdown database
- Copy by O/S all datafiles, temp files, control files and redo logs. That will be my backup before testing.
- Open database, test and modify data
- When test is finished, shutdown database
- Copy and replace by O/S all datafiles, temp files, control files and redo logs from backup place
- Open database as standby and apply all archived redo logs needed.
Would be it work without problem or should I copy other files?

it comes under Refresh of database, use --> cleanup --> restore.
If its enterprise edition , you can use procedure mentioned in this note How To Open Physical Standby For Read Write Testing and Flashback [ID 805438.1]

Impact of force_logging on standby database in 10g?

Hi there,
We have a 10.2.0.5 database from which we want to setup a standby database...
We took a hot backup of the primary and send it to the standby server but at that time we realized that force logging is not enabled at the Primary before we took the hot backup!
Can you please suggest what are our options at this stage without losing any data and without a need to redo the hot backup again since it is a huge database?
- If we turn the force_logging on now(on Primary) and then set up the standby using the backup taken prior to force_logging ON - would it cause any issues?
Any help would be greatly appreciated.
Thanks.

No it won't because the hot backup is a copy period. So do it ASAP and the Archive will handle the rest.
So your hot backup is the Standby copy ( exact copy ). Just make sure forced logging is on and the archive with keep the data in sync.
If you delay then you are up the creek without a paddle as NOLOGGING actions are bound to occur and then the Standby data will not match the Primary.
If you have doubts your best option is to roll the standby forward using RMAN Incremental Backups :

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?

Import data from 10g to oracle 9i

hi,
how can i import data fom 10g to 9i R2?

Follow this thread :
exp/imp between 10g and 9i
Essentially, you must
1. Install a 9i server or administrative client environment.
2. Configure SQLNet connectivity (tnsnames.ora) to the 10g database.
3. Run exp from the 9i environment, connected to the 10g database.
4. Create a 9i export dump file.
5. Import this into your 9i target database.
If you have different charactersets, you must be mindful of the setting of NLS_LANG in the environment that you run "exp" and "imp" in.

Upgrade PHYSICAL STANDBY database to 10g from 9i

Hello everybody,
Please can you provide me the details for Manual upgrading 9i STANDBY database to 10g. Any special parameters that we have to set on the Primary database..
Any sites with the information available would be great.
Thanks everybody for your help.

There is no in-place upgrade process to move from 9i to 10g. You have to upgrade your primary and then reinstantiate your standby (using Oracle10g). You may like to keep your 9i standby in tact until your upgrade of 9i primary to 10g is completely successful.....just to ensure that you have a fast, easy and reliable fall-back plan.
Thanks

What time the Oracle Data Mining 10g ?

What time the Oracle Data Mining 10g ?

If you are referring to the 10.1 release of the ODM user interface, that should be available in beta form very shortly(a couple weeks) with the final release very soon after that.

Can I export 8i data using 10g client to import it into 10g

Dear All,
I have 8i databae and want to import few of its data in 10g.
Can I do it and how?
I tried to export using 10g client but not worked.
Aqeel Nawaz

Hello,
You should export the data of the 8i database using the *8i* export utility.
Then, you import the generated dump to the 10g database with the *10g* import utility.
Else, you may care of the character set so as to avoid conversion.
Sorry Azar, I didn't see that you answered already.
Hope this help.
Best regards,

Standby data update/refresh

Oracle 10.2.0.1.0, Redhat 4
I have setup Standby db by using 'Data Guard Concepts and Admin' manual.
1. Looks like my standby db is updated only when redo switch takes place on the primary.
Is there not a way to get standby data to be updated quicker like every 2 minutes or after every commit?
2. If I mess up data on standby is there a nice and quick way to refresh all data from primay.
(Advance) Thanks for any help/suggestion.

If you want real-time apply, you would need to have standby redo logs configured

http://download.oracle.com/docs/cd/B19306_01/server.102/b14239/log_apply.htm#i1023371
If you're interested primarily in non-disaster recovery uses, I'd tend to suggest looking at Active Data Guard in 11g. While you certainly can use a logical standby for test databases, I'm not sure that it makes a whole lot of sense to do so unless you are interested in also using the disaster recovery approach. For most situations, it's going to be easier to just restore a backup of the production database to the test server every month or two (which also verifies the backup) than to try to maintain a logical standby as the test server and to deal with flashing back the test server to a point in time to re-apply changes. I'd also be hesitant to have a situation where my production database was buffering a pile of changes for days or weeks at a time because users were in the middle of a test cycle and didn't want their changes backed out.

Logical Standby Data Consistency issues

Hi all,
We have been running a logical standby instance for about three weeks now. Both our primary and logical are 11g (11.1.0.7) databases running on Sun Solaris.
We have off-loaded our Discoverer reporting to the logical standby.
About three days ago, we started getting the following error message (initially for three tables, but from this morning on a whole lot more)
ORA-26787: The row with key (<coulmn>) = (<value>) does not exist in table <schema>.<table>
This error implies that we have data consistency issues between our primary and logical standby databases, but we find that hard to believe
because the "data guard" status is set to "standby", implying that schemas' being replicated by data guard are not available for user modification.
any assistance in this regard would be greatly appreciated.
thanks
Mel

It is a bug : Bug 10302680 . Apply the corresponding Patch 10302680 to your standby db.
