Standby Database problem (10g)

Dear Oracle Experts,
I have primary and physical standby instance running. Due to whatever reason, the server running the standby instance is restarted.
After the standby instance restart, I have observed that 2 archivelogs that appear in primary instance was not in standby instance.
I have queries the v$archive_gap but it does not report anything gap.
What does that imply? Does that means there is no gap? But clearly 2 archivelogs are missing. Its too confusing.
If it means the standby instance is no longer sync with primary instance, is it possible to apply manually the 2 missing archivelogs as I have them.
Thanks in advance.

Yes you can apply the logs manually but before that please let me know whether you got the logs in the standby database.
Use the following command to see the log file no and whether its applied or not
select sequence#, applied from v$archived_log where applied='YES';
If you can see those logs in the standby database dont do any thing it will auto matically apply those logs, but for long time if it does not apply then remove that log and do the following steps
1) If the archive logs is in ASM then use RMAN command.
Take the backup and restore it in the standby server using the following command
RUN
SET ARCHIVELOG DESTINATION TO '/data/RMANBKP/restore';
RESTORE ARCHIVELOG from sequence 123 until sequence 125;
then
2) Register those archivelogs using the following command
Alter database register logfile '/data/RMANBKP/restore/123.dbf';
or
Alter database register or replace logfile '/data/RMANBKP/restore/123.dbf';

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?

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]

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

Hi.
I am facing issues to configure "for monitoring" the standby instance of a 10g database. If someone on this forum have experience, please share, will be greatly appreciated.
Thanks

FYI we have a tar open on this "standby databases not monitored correctly" ie grid is trying to collect metric from a sb db when it can not b/c its only mounted. The fix will be in 10.2.0.4. We are pushing for a back port to 10.2.0.3 b/c we missed a corruption in our sb db b/c we could not monitor the values and apply different templates.

Logical standby database problem

i have setup logical standby database on my pc . Everything was working fine . Logs were applied.
But i tried testing few things on standby and issued few commands on that.
After that the logs were not applied. i tried to restart that also dint work.

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 :

Standby Database in 10G

Hello all,
I have to build a physical standby environment on oracle 10g database. I have done this with oracle 9i. i have never done in 10g.
so is there any deference in both or both installtion are just same ?
Thanks in advance!!
Pankaj

It's pretty much the same. However, if you refer to the 9iDG and the 10gDG setup examples, I noticed a few differences in the way the init parameters are used.

Standby Database in 10g SE

Hello,
I have to create standby DB on AIX. I know, it's not possible to use the DataGuard with Oracle DB Standard Edition, so I must do it with an older technique. I want to set up remote location for archived logs with OPTIONAL and REOPEN options. Primary database is backed up automatically by RMAN. During that operation old archived logs are deleted. I know that RMAN will not delete my old archived logs on standby machine. How can I do it? Do I have to schedule new jobs on standby to delete there old archived logs? Can I add entries to RMAN scripts on my primary site to delete archived logs on standby server?
Thanks
Pit

On Niall Litchfield's blog are links to a presentation You Probably Don't Need DataGuard, along with scripts for setting up and maintaining a standby system. The scripts are Windows based if memory serves, but they should give you a pretty good idea of what your AIX scripts need to do.

How to stop and cancel physical standby database (ORACLE 10g)

Dear All,
I have physical standby setup and I want stopped for the time being that to use the database as an normal DB (standalone inestance).
Kindly advise and show me how do I do that.
Regards,

executing below query on primary db stops log shipping to standby.......i think this is sufficient for disabling your physical standby setup temporary
alter system set log_archive_dest_state_2=defer scope=both;
In future if you want your dataguard setup back..............you can rebuild the standby and enable the log_archive_dest_state_2 parameter.
