Logical Standby Database in NOARCHIVE Mode

Hi,
I have configured a Logical Standby Database for Reporting purposes. A Physical Standby Database is running for MAA. i.e. in case of Role Transition (switch/Failover) the Physical Stdby Db will get the role of the Primary.
The logical standby database is creating a lot of Archive Redologs files, nearly every minute. Redolog files are 50MB and there is no work done in db during the time. I'm NOT using Standby Redolog files.
Is there a need for logical standby database to be in NOARCHIVELOG mode? The Primary is definatley in ARCHIVELOG mode.
Thanks for any responses.
regards
Sahba

hi,
well there are two things to the above:-
1. there was an archive file nearly every minute:
this is due to a db recovery. for some reason, the db was in inconsistent state, after a sudden shutdownof the OS. I was on a test environment, on windows vista, unfortunately. unimportant ... a reboot solved it.
2. Logical standby db in NOARCHIVE MODE when setup for the purpose of Reporting.
As long as the MAA configured for the primary db, such as physical standby db, and a second, the logical standby db setup purely for the purpose of reporting, which then can run with NOARCHIVELOG mode, after converting the physical standby db to logical.
logical standby db uses Streams architecture, so this method brings cost, time and performance advantages to the customer.

Standby Database (Archive Log Mode)

I'm going to be setting up a standby database.
I understand that the primary database must be in archive log mode.
Is there any reason for the standby database to be in archivelog mode?

Since your primary Db is in archive log mode, so will be your standby, when it is made primary.But. you can use STANDBY REDO LOGS from 9i version, where these Standby Redo Logs then store the information received from the Primary Database.
As per metalink:-
>
Standby Redo Logs are only supported for the Physical Standby Database in Oracle 9i and as well for Logical Standby Databases in 10g. Standby Redo Logs are only used if you have the LGWR activated for archival to the Remote Standby Database.If you have Standby Redo Logs, the RFS process will write into the Standby RedoLog as mentioned above and when a log switch occurs, the Archiver Process of the Standby Database will archive this Standby Redo Log to an Archived Redo Log, while the MRP process applies the information to the Standby Database. In a Failover situation, you will also have access to the information already written in the Standby Redo Logs, so the information will not be lost.

Running a physical standby database in noarchivelog mode

Primary Database: 2 node rac cluster, 11.2.0.2 GI and RDBMS
Standby Database: single instance 11.2.0.2
OS: AIX 7.1
Hello,
I'm in the process of implementing a data guard standby system. To make this system simpler to admin, I want to run the standby database in NOARCHIVELOG mode. This standby is used only as a mirror of production (to be copied to a 3rd site for separate user activity) and will never be switched to active mode. Maintaining another set of archive logs seems to be redundant to me and another point of failure, so I want to disable archiving. I wanted to ask if any of the DG experts on the forums have ever had experience with this? Does anyone know if this is recommended? I've searched the Oracle Data guard documentation online... it says that the primary obviously needs to be in archive mode, but I'm not seeing anything specific about the standby. Please let me know if anyone has experience with this.
Thanks

Hello again;
If this is the case, then I have nothing to worry about here. Does that sound right to you?Yes.
For this :
b) monthly, shutdown this system and copy it to a 3rd site to host a separate set of business activityI would consider RMAN Duplicate in which case you may avoid the shutdown.
And for this :
resync the "mirror" with productionAll you have to do if DEFER the primary to the standby, then ENABLE and Data Guard will catch up.
--- Will post a detailed example here in a moment.
Right at the first of the year they wanted to work on our Primary server room ( Power ). What I did was switchover to the Standby but I kept log_archive_dest_state_2 on the new primary set to DEFER. Then I shutdown
all the databases at the Primary site. At the end of work two days later I started the databases at the Primary site in standby mode. Switched log_archive_dest_state_2 to ENABLE. When the databases were back in SYNC
I did another switchover and it was done. I used TAF and none of the users even noticed.

Starting Physically Standby Database in Mount Mode

Hi All
I have configured Data Guard using Oracle 10g 10.2.0.4.0 (64 bits) on Windows 2008 Server (64 bits) Release 2 Enterprise.
Data guard configuration was OK as the message from "Enable Configuration DG1" was "SUCCESS" for both
Primary and Standby Database. I have also set both Databases and TNS to start Automatically whenever Windows Starts.
The Problem is as long as the Standby Server is running, there is No issue.
But when we Restarts the Backup Server, Physically Standby Database is Started and TNS is also Started,
but Archives are not received until I physically do the following steps so that it can received the Archives.
SQL> startup nomount;
SQL> alter database mount standby database;
SQL> alter database recover managed standby database disconnect from session;
Is there a way to start Physically Standby Database in Mount mode when windows started.

How to open a "manual" Physical standby database in read/write mode

Hi,
I am running Oracle Database 10g Release 10.2.0.3.0 - 64bit Production Standard Edition on Linux version 2.6.9-42.0.8.ELsmp ([email protected]) (gcc version 3.4.6 20060404 (Red Hat 3.4.6-3))
I've created a physical standby database, but since I am running Standard Edition, I am not using the DataGuard features. I use the rsync utility to copy over the archivelogs to the standby database, and I apply them periodically to the standby database.
The standby database is started this way :
startup nomount pfile='/u01/oradata/orcl/initorcl.stdby';
alter database mount standby database;
Everything runs perfectly fine, I can do "alter database open read only" and then I can do selects into tables to confirm that everything is up to date.
The thing is, if I shutdown immediate the database, then do just startup :
shutdown immediate;
startup;
The database opens with no error messages, but is still in read-only mode...
I read that the default behavior for a standby database is to open read-only, like I am experiencing, but I would like to know what is the right way to open it correctly in read-write mode (I understand that after that, my standby will not be standby anymore and that I will have to recreate my standby database).
Thanks,
Mat

Hello,
There're features which allows you to open a Standby database in Read/Write mode but for all I know
it needs Entreprise Edition.
In Enterprise Edition you can use Logical Standby database. More over, for Physical standby there's
a way by using flashback database so as to rolling backward the database and avoiding to recreate
the Standby.
In Standard Edition I'm afraid that you'll have to recreate your Standby database.
Best regards,
Jean-Valentin

Should the STANDBY database be in NOMOUNT Mode?

Hi There,
Just setup DataGuard and want to monitor the primary and standby databases via the grid. However, I can not configure the standby database because the standby database is in NOMOUNT mode. Was I suppose to mount it? If not, how do I configure the standby database with the enterprise manager in NOMOUNT.
Thanks.
J

Jennifer;
Yes the standby should be in MOUNT mode before apply starts. Or No, to NOMOUNT if you prefer.

Do I need to use standby database in begin backup mode to take the backup?

Hi All,
I have a 10g(10.2.0.4) primary database with standby on a solaris platform. I need to create another standby database for the same primary.
I have stopped the recovery on existing standby database and started copying(os copy) the files from existing standby to 2nd standby server. However I haven't kept the existing standby database(mounted) in begin backup mode. Is it okay?
Thanks,
Arun

Physical Standby Database (Protection Mode)?!!

Hi,
I have configured a physical standby database to use Real-time Apply, but i noticed that the protection mode of the database has been changed from "Maximum Performance" to ''Maximum Availability"..
log_archive_dest_3='service=phystby OPTIONAL LGWR SYNC AFFIRM reopen=120 valid_for=(online_logfiles,primary_role) db_unique_name=phystby'
Any body to explaine??
Regards,

LGWR SYNC AFFIRM
These are the options are used in maximum protection mode ,in which oracle will write the information in both the server(primary and standby) and this write occurs at same time.
oracle write the information in online redo logfile of both the server simultaneously.
and this option ensure no data loss will occurs if primary will fail.
SYNC related with Network transmission mode.
AFFIRM related with disk write option.
LGWR describe Redo archival process.
Thanks

Opening a Standby Database in Read-Only mode

Is there anyway to open a Standby database up to date as of a certain time? I'm currently using the 2 commands to get close to the time required.
ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT;
ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL;
Such as, similar to this? RECOVER DATABASE UNTIL TIME '2012-01-25:15:00:00';
We're on 11.1.0.7, which I'm currently very unhappy with.
Thanks for any help, as my google-fu hasn't worked today.
James

Maybe
I did a quick test :
8:42 open the databases and start recovery
8:43 check status from primary
Shows sequence 75
and "TO STANDBY" for switchover status
Did log switches at 8:44, 8:45, and 8:46
8:50
SQL> alter database recover managed standby database cancel;
SQL> RECOVER STANDBY DATABASE UNTIL TIME ' 2012-01-25:20:43:00';
Media recovery complete.
SQL>
8:52
SQL> alter database recover managed standby database disconnect from session;
Database altered.
Check status
TO STANDBY and sequence 78Still need to check alert logs and do another log switch. It checks out so the quick test works.
However the quick test is incomplete since there was no before and after data in the test and the time period was very short.
Andy may be right, but I would test, test test. ( if you do please let us know the results )
Thanks Andy!

Later
After sleeping on this I decided my first thought is probably correct. You cannot go back in time and still be in sync. While the test statement did not error or produce any alert log entries, it probably did nothing. Oracle is smart enough to know you cannot have your Cake and eat it too.

Hi all,
I have setup standby database ,and it was working fine,but when i switch archives in big numbers,the archives are being shipped to standby location but the log apply is very slow,
what could be the reason for this.?
my db version:10.2.0.3
linux box

Hi, you must review the alert logs and the standby logfiles and find some error, the apply process works asynchronous, but probably exist some problem.
Regards.

Logs are not getting applied in the standby database

Hello,
I have created a physical standby database and in it the logs are not getting applied..
