Standby database showing open resetlogs/we dont want to resetlogs
Dear All,
I created standby database from cold backup in oracle 8.0.5/sunsolaries
After appling archivelog from primary database i am tring to open in read/readwrite mode
but its asking to resetlogs.
I want to avoide resetlogs and open the database how i can?
Regads,
sami
Hi Sami,
It may be due to redo logs are not applied in standby so apply them as well and then try to open a database. Did you create controlfile from primary as standby? I mean did you use below command?
alter database create standby controlfile as '<location'; so without that it'll think that it's primary database. Change init.ora files accordingly. Are you creating a duplicate database or standby database?
Thanks,
Keyur

Switchover_status in standby database showing NOT ALLOWED
Hi All,
My oracle database version is Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - 64bit on windows platform.
I need to perform switchover activity with dg_broker=TRUE.
When I checked the status of DR database I found that switchover_status is NOT ALLOWED rather than SESSION ACTIVE or TO PRIMARY.I have doubt whether switchover can be done successfully or not with this configuration?

1.In this case,is switchover is possible?No
2.If not possible then what will be the next step?If the value in the SWITCHOVER_STATUS column is SESSIONS ACTIVE, identify and terminate active user or SQL sessions that might prevent a switchover from being processed.
If, after performing these steps, the SWITCHOVER_STATUS column still displays SESSIONS ACTIVE, you can successfully perform a switchover by appending the WITH SESSION SHUTDOWN clause to the
ALTER DATABASE COMMIT TO SWITCHOVER TO PHYSICAL STANDBY statement.
3.Is this will impact to our production database when switchover is not successfully perform?
4.In DR RFS is idle,why?Can you paste here log_archive_dest_n paramete which is you are using for transport?
Did you using DELAY attribute in log_archive_dest_n parameter?

Activity monitor always shows apps that i dont want running
I'm on 10.4.9.
When i open activity monitor, i see that there are programs (or whatever they are) running, that are clearly not important, as most of them are related to various programs or devices that i've installed.
I find myself quitting them when i want to play games or use processor intensive programs (they do take up a little %CPU)... but after a certain amount of time they seem to come back, especially when i restart my computer.
Is there any way to keep them from loading?
Here are a couple examples:
MicrosoftMouseHelper (obvioiusly related to my optical mouse)
HP IO Classic Proxy (related to my printer, which i keep unplugged except for printing)
Print Daemon (see above)
HP Event Handler (see above)
iTunes Helper (iTunes related, and i don't need any help ;))
note that when i turn any of these off, i don't lose any functionality in anything they're linked to (my mouse works the same, as does iTunes and my printer)
thanks.
Mac OS X (10.4.9)Hi Max,
Check your startup items, as long as any of those items are in that list they will keep coming back.
System preferences > accounts > startup items.
I think you will find iTuneshelper and microsoftmouse helper there, take them off that list and they won't bug you again unless started by you or an app that needs them. -
TV shows....DONT WANT TO USE ITUNES 7
I just got done getting rid of itunes 7 , it was TERRIBLE on my computer.
I am able to watch all my tv shows from before and even Lost from last week. Now when I try to download Lost from THIS week, itunes won't let me...says I need to upgrade! I have already paid for all my Lost episodes and I don't want iTUnes 7 anywhere near my computer!
what can I do????From what I understand volume Logic is working on a update for itunes 7 for windows.
I don't know of a perfect peice of software personally, but I hear real player can handle most ipods, might try that OR goto iTunes 7 and install a updated volume logic plug in for windows when it becomes avalible -
CF card opens IMovie but dont want it to?

How can I make it stop this annyoing habit?You might also try launching Image Capture then check its Preferences to see is something is set there.

Did you check the Home page setting to be sure that there aren't two pages separated by a pipe (|)?
If that isn't the case then delete or rename the files prefs.js and user.js in the Firefox Profile Folder.

Ok i plug in my ipod to charge it and itunes flies up and it starts updating...how do i prevent that from happening?
DELL Windows XPthis happens because your iPod is set to auto-update and it is automatically going to open iTunes when you plug in your iPod to update it. So simply go to Prefrences --> iPod --> and check manually update this iPod.

Is there a way to apply archive logs, standby DB is opened with 'resetlogs'
Hi All,
I have setup a standby database (Oracle 10g SE). I applied hot backup and archive logs to the standby database till yesterday. I have opened the standby database using 'alter database open resetlogs;" and validated the application functionality using the standby database.
Now I want to regularly apply logs from the Primary database to the standby database, but today I have opened the standby database using 'alter database open resetlogs;"
Need assistance to know the way to apply archive logs, once the standby database is opened with 'resetlogs' option to keep it in sync with the Primary database.
Thanks
KunalWelcome to OTN,
I have setup a standby database (Oracle 10g SE). I applied hot backup and archive logs to the standby database till yesterday. I have opened the standby database using 'alter database open resetlogs;" and validated the application functionality using the standby database.Standby opened with *resetlogs* ? What you did? have you performed failover of standby database?
Now I want to regularly apply logs from the Primary database to the standby database, but today I have opened the standby database using 'alter database open resetlogs;"
Need assistance to know the way to apply archive logs, once the standby database is opened with 'resetlogs' option to keep it in sync with the Primary database.Have you enabled Flashback & created Restore point? If so you can do it.. If not rebuild standby again.

Redo log files are not applying to standby database
Hi everyone!!
I have created standby database on same server ( windows XP) and using oracle 11g . I want to synchronize my standby database with primary database . So I tried to apply redo logs from primary to standby database as follow .
My standby database is open and Primary database is not started (instance not started) because only one database can run in Exclusive Mode as DB_NAME is same for both database. I run the following command on the standby database.
SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION;
It returns "Database altered" . But when I checked the last archive log on primary database, its sequence is 189 while on standby database it is 177. That mean archived redo logs are not applied on standby database.
The tnsnames.ora file contains entry for both service primary & standby database and same service has been used to transmit and receive redo logs.
1. How to resolve this issue ?
2.Is it compulsory to have Primary database open ?
3. I have created standby control file by using command
SQL> ALTER DATABASE CREATE STANDBY CONTROLFILE AS ‘D:\APP\ORACLE\ORADATA\TESTCAT\CONTROLFILE\CONTROL_STAND1.CTL‘;
So database name in the standby control file is same as primary database name (PRIM). And hence init.ora file of standby database also contains DB_NAME = 'PRIM' parameter. I can't change it because it returns error of mismatch database name on startup. Should I have different database name for both or existing one is correct ?
Can anybody help me to come out from this stuck ?
Thanks & Regards
Tushar LapaniThank you Girish. It solved my redo apply problem. I set log_archive_dest parameter again and then I checked archive redo log sequence number. It was same for both primary and standby database. But still table on standby database is not being refresh.
I did following scenario.
1. Inserted 200000 rows in emp table of Scott user on Primary database and commit changes.
2. Then I synchronized standby database by using Alter database command. And I also verify that archive log sequence number is same for both database. It mean archived logs from primary database has been applied to standby database.
3. But when I count number of rows in emp table of scott user on standby database, it returns only 14 rows even of redo log has been applied.
So my question is why changes made to primary database is not reflected on standby database although redo logs has been applied ?
Thanks -
Test physical standby database in dataguard
Hi all,
I had a successfull dataguard implementation for oracle 9r2.
Primary and standby databases are on different nodes, logs from primay are shipping and applying to physical standby database successfully.
As these database are for oracle 11i ebs, so for testing dataguard status i had created a table manually having columns date and remarks. Periodically i insert few records in this table in primary database and then chek this tabel in standby database (by opening in read only mode).
Now i want to test physical standby database with applications tier but don't want to disturb origional primary database.
as these are the normal switchover steps
1) at primary db
ALTER DATABASE COMMIT TO SWITCHOVER TO PHYSICAL STANDBY WITH SESSION SHUTDOWN;
2) at standby
ALTER DATABASE COMMIT TO SWITCHOVER TO PRIMARY;
3) at primary, now this will be the stand by database
SHUTDOWN IMMEDIATE;
STARTUP MOUNT;
4) at standby, now this will be the primary database
SHUTDOWN IMMEDIATE;
STARTUP
My concern is if i skip step 1 and 3 and only execute step 2 and 4, will that be applicable for my requirement, or there is some other way to achieve this goal.
Regards,
KenTo avoid touching the primary production DB, you may try to use the following command on your standby database side:
alter database activate standby database;
This will turn your standby database to primary database, however the log will be reset and this means you will need to rebuild your DR.
Another way is to use flash back feature on your standby database, activate it and revert back to the flashback point when the DR testing is done. -
About physical standby database
We have physical standby database(10g). what are steps to put standby database in ready only mode for time being and then put it back in primary-secondary relationship once cheking is done?
Cancel the redo Apply
SQL>ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL;Open The database
SQL>ALTER DATABASE OPEN;Do your stuff.
Once done, shut it down, then mount it again and resume the redo apply
SQL>SHUTDOWN IMMEDIATE;
SQL>STARTUP NOMOUNT;
SQL>ALTER DATABASE MOUNT STANDBY DATABASE;
SQL>ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT;If you use real-time redo apply, you may want to issue the following command instead of the previous one.
SQL>ALTER DATABASE RECOVER MANAGED STANDBY DATABASE USING CURRENT LOGFILE DISCONNECT;...and pretty much that is it.
Be aware that while running it in read-only mode, no logs from the primary are being applied. Also you may hit some bugs when you open your standby database. So if this standby is your production one, make sure you know how to deal in a situation when you need to resolve possible issues.
Jason Arnell has explained one possible buggy scenario on his blog - LINK.

Firstly you can use "*select sequence#,first_time,next_time from v$archived_log order by sequence#;"* command in mount stage itself.No need to open the standby database in ready only mode.
No rows selected in mount stage also.
The V$ARCHIVED_LOG fixed view on the physical standby database shows all the archived redo log files received from the primary database.
sql> select * from v$archived_log;
no rows selected.
and No archived logs received from primary database to physical standby . i think here i wrongly configure parameter file.
sql> RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION; -- > start Redo Apply
When you do log switch on the primary are the archive logs getting transferred to the standby database???Is there some error in the alert log file in the primary database.
No..

How to apply archivelog with gap on standby database
Hi All,
Oracle Database version : 9.2.0.6
Following is my sequence of commands on standby database.
SQL>alter database mount standby database;
SQL> RECOVER AUTOMATIC STANDBY DATABASE UNTIL CHANGE n;
ORA-00279: change 809120216 generated at 07/24/2006 09:55:03 needed for thread
1
ORA-00289: suggestion : D:\ORACLE\ADMIN\TEST\ARCH\TEST001S19921.ARC
ORA-00280: change 809120216 for thread 1 is in sequence #19921
ORA-00278: log file 'D:\ORACLE\ADMIN\TEST\ARCH\TEST001S19921.ARC' no longer
needed for this recovery
ORA-00308: cannot open archived log
'D:\ORACLE\ADMIN\TEST\ARCH\TEST001S19921.ARC'
ORA-27041: unable to open file
OSD-04002: unable to open file
O/S-Error: (OS 2) The system cannot find the file specified.
I have check the last sequence# on standby database which is 19921. And I have archivelog starting from sequence# 20672 onwards. When I am trying to apply archive log starting from sequence# 20672 , it is searching for 'D:\ORACLE\ADMIN\TEST\ARCH\TEST001S19921.ARC' file and cancel the recovery. Please note that I don't have those missing archive on Primary server as well. So How can I apply the remaining archive log which I do have from 20672 onwards.
I hope I am not creating any confusion.
Thx in advance.Hi Aijaz,
Thx for your answer. But my scenario is bit complex. I have checked my standby database status which is not running in recovery mode. I have tried to find archive_gap which is 0 on standby server. I am copying all archived log from primary to standby thru the script every 2 hour and appying them on standby. After applying, the script is removing all applied log files from primary as well as standby. So it is something like I have archivelog from 1,2,3,7,8,9,10. So 4,5 and 6 archivelog are missing which is required when I am trying to recover standby database. Also note that I want to apply 7,8,9,10. I will loose some data from those missing archive but I have cold back any way. I don't have those missing archivelog files(4,5 and 6) anywhere at all. So how can I recover standby database. I am using standby just for the backup purpose.
I hope my question is clear now.
Thx in advance
