If the production database i down, how to switch to standby database using the replication environment in ASsE

This question is in Business Continuity Plan (BCP)
if the production database is down, how to switch to standby database using the replication environment in ASE

Assuming you're referring to Sybase's Replication Server (repserver) product ...
Repserver moves data changes from one database to another.
Repserver can't 'switch' your application to use a different database; something outside of repserver has to do the actual switching.
If your application happens to be connecting to your ASE via Sybase's OpenSwitch (or similar) product, then OpenSwitch would be responsible for switching your application to use the standby database. Whether you have OpenSwitch perform the switch automatically, or via a manual command, is up to your BCP requirements.
If your application connects directly to ASE then you'll have to decide how/when to get your application to switch to the standby database. In the simplest form this would require shutting down the application, making sure replication is quiesced (ie, all in-flight transactions have been applied to the standby database), modify the interfaces/sql.ini file (used by your application) to point to the standby database, make any customized changes to the standby dataserver/database (eg, unlock application logins, take databases out of 'dbo use only' mode, etc), and startup the application (at this point it should connect to the standby database per the changes to the interfaces/sql.ini file).

Restore production from standby database

Hi,
I would like to make a standby database for my production database.
But, I have a basic question to restore my production database from standby database. There is a method to make it ?
If I lost all files from production database, how to restore from my standby datase (which become in this case my new production database) ?
thanks in advance for your help.
gnom92.

* I make a copy datafiles from my new production database (old standby database) on old production (where crash)
* With my old production database, I make a standby database on new production database (old standby)
* I can close the new production database and open the new standby database in read / write mode, and this is my production database.
* After what I recreate my standby database (old standby,newproduction), or can I return in recover standby mode ?
thank you very much for your patience.

How to create standby database by using duplicate

Dear all,
How to create standby database by using duplicate,is there some doc to read?

Hi;
You can use

Switch the standby database

Hi Everybody,
Today in my test db,
I switched the standby database to physical primary database,
it is sucedded.But after that when i go to make its original state means i want my current standby (ie original primary) as a primary,
i got error that flashback feature is not on .Then how can i do this.
Regards
Hemant

then for test ,
in primary i issue--shut immediate
in standby database --altetr database recover managed standby database cancel;
alter database recover managed standby database finish;
alter database commit to switchover to primary;
alter database open;
NOW I CHK THAT THE PRIMARY DB IS WORKING FINE.You performed Fail over , You can get back your standby(current-primary).
If you create a restore point(with flashback enabled) then only you can able to restore to that particular point..
Since you have not configured, You have no option.
*Restore Points in Oracle10g Release2 [ID 330535.1]*
THEN AFTER 15 MINTS ,
I WANT THE ORIGINAL STATE,HO W CAN I DO THIS,FLASHBACK FEATUE IS NOT ON.Now its not possible.

Recover Primary Database from Standby Database

Hi all,
I'm trying to understand how to use physical standby database in order to have a backup from a primary database.
The first part is very clear. I supose I have a physical standby database ready and archiving from a primary database but the second part is the problem.
1. Now I supose that my primary database is gone... not just a logical corruption but a physical disaster such a fire o something worst.
How to recover the primary site from the physical standby database??????????
2. Just a logical corruption in primary database. How to syncronize with the standby database that it's the one who has the right data???
Thanks in advance.

How to recover the primary site from the physical standby database?1. Ensure that you DO have a Primary Site up and running. It might be the same building. It might be another building. Management might decide to switch to another city. (BTW, all of this should be defined in the D.R. / B.C.P. documentation).
The (possibly new) Primary Site has to have the required hardware , O.S etc.
2. Take a backup of the Standby and restore it to the (possibly new) Primary.
Actually, the Standby becomes the new Primary and the new site that is setup becomes the Standby. This continues until management decides to switch over.
Just a logical corruption in primary database.Take a backup of the Standby and restore it to the Primary. You have to suffer an outage. Note : If only one or few files on the Primary are physically corrupt (and offline), you could backup the selected files from the Standby and RESTORE and RECOVER on the Primary !

Failover from standby database to primary database

Hi,
Can anyone suggest me, How to do " Standby DataGuard database to primary database (dataguard)".
Kindly Give me steps.
Thanks,
Shweta

Hi
Follow these steps
Oracle switchover operation:
1.     Check and verify the role parameter on the v$parameters both primary and standby
On Primary
Log_archive_dest_1=”this is the local archive destination”
+Log_archive_dest_2=”This is the Service [TNS ENTRY]”+
Log_archive_dest_state_1=Enable
Log_archive_dest_state_2=Enable
Fal_server=”this should have the tns entry for the standby
Fal_Client=”this should have the tns entry for the primary
Standby_archive_dest=”This should have the Location where the archive located”
Standby_File_Management=AUTO
On Standby
Log_archive_dest_1=”this is the local archive destination”
+Log_archive_dest_2=”This is the Service [TNS ENTRY]”+
Log_archive_dest_state_1=Enable
Log_archive_dest_state_2=DEfer
Fal_server=”this should have the tns entry for the primary
Fal_Client=”this should have the tns entry for the standby
Standby_archive_dest=”This should have the Location where the archive located”
Standby_File_Management=AUTO
2.     Down all the applications connects to the database
3.     Shutdown both primary and standby databases
4.     For RAC Keep Only one primary and One standby up and all other nodes should be down
5.     Check the Primary database on Open mode and the Standby database on mount stage
6.     On Primary
SQL>select switchover_status from v$database;Sessions Active or To standby will be appearing on the result
SQL> alter database commit to switchover to standby with session shutdown;
SQL> shutdown Immediate;
SQL>startup nomount;
SQL>alter database mount standby database;
SQL>Alter system set log_Archive_dest_state_2=defer;7.     On Standby
SQL>select switchover_status from v$database;it is acceptable to have Sessions Active or To Primary
SQL>alter database commit to switchover to primary with session shutdown;
SQL>shutdown immediate;
SQL>Startup;
SQL.>Alter system set log_archive_dest_state_2=enable;8.     On Primary
start the managed recovery
SQL>Alter database recover managed standby database disconnect from session;9.     Check the log shipment is working from New Primary to New Standby Using
SQL>Alter system switch logfile; ---- On New Primary.check the alert log on both Primary and Standby for the log shipment and Media recovery.
10.     If the switch over fail issue the following statement on standby (ORACLE 9i)
SQL> alter database recover managed standby database finish skip standby logfile ┘
SQL> alter database commit to switchover to primary┘
SQL> shutdown immediate;
SQL> Startup;11.     If this don’t work please issue the below statement
SQL> alter database activate standby database skip standby logfile;12.     If the switch over fail issue the following statement on standby (ORACLE 10g and above)
SQL> alter database recover managed standby database finish force;
SQL> alter database commit to switchover to primary;
SQL> alter database open;
SQL> shutdown Immediate;
SQL> startup;13. Added the temp file to your temp tablespace
If you follow the steps (10,11 & 12 ) you have to recreate the standby again. those steps are actually fail over steps. Hope this will be helpful
Cheers

This would be a database duplication from backup with RMAN. A Catalog will help, particularly as you are working in a Data Guard environment, but it is a straightforward and well documented operation:

hi.
Its not necessary its a otherway around to recover datafile from this backupset and apply archivelogs to make datafile consistent.
yes, it ain't the right way to restore backup to primary location.
so how would i connect to standby database with primary and recovery catalog.
i need to connect to recovery catalog and primary site because i need to restore to primary location and recovery catalog contain all metadata and backupsets related information.
i also tried the following steps from oracle documentation.
Connect to the standby database as the target database:
CONNECT TARGET sys@standby
You are prompted for a password:
target database Password: password
Connect to the primary database as the auxiliary database:
CONNECT AUXILIARY sys@primary
You are prompted for a password:
target database Password: password
Back up the datafile on the standby host across the network to a location on the primary host. For example, suppose that /disk1/df2.dbf is the name of datafile 2 on the standby host. Suppose that /disk8/datafile2.dbf is the name of datafile 2 on the primary host. The following command would copy datafile 2 over the network to /disk9/df2copy.dbf:
BACKUP AS COPY DATAFILE 2 AUXILIARY FORMAT '/disk9/df2copy.dbf';
Starting backup at 06-NOV-08
using target database control file instead of recovery catalog

The Oracle Solaris Cluster concepts guide has some information on which zone model to choose:
http://docs.oracle.com/cd/E18728_01/html/821-2682/gcbkf.html#scrolltoc
When managing a Solaris zone with the HA Zones agent, the cluster basically regards the non-global zone as a blackbox.
As such you can either start the Oracle database as part of the runlevel/SMF startup of the non-global zone, or you can use the sczsh or sczsmf component and use your own scripts to start, probe and stop the Oracle database.
Usage of the standard HA Oracle data service is not supported in combination with the HA Zones agent.
If you require a more fine grained control of services running in non-global zones, why not setup a zone cluster and then having HA Oracle failover the Oracle database between non-global zones?

Thorsten

Create dev database from standby database

Hi folks,
I need to create a dev database by using RMAN's method of cloning. But, since it is business hours and the production database is being used at a very high rate, I cannot carryout the cloning by connecting the primary database as it may cause performance slowness.
The time allotted for the activity is also very short. We have a standby database created for the primary database. So, my question is it possible for me to create the dev database using the standby database ?
Database version is 11.1.0.6 and I can go ahead with the active database feature.

Yes, you can clone from the standby database. Follow the below steps.
1. Check if your standby database is in sync with the primary database.
2. Cancel the MRP on the standby database.
alter database recover managed standby database cancel;3. connect to standby as target database and dev database as auxiliary
rman target sys/<pwd>@<standby-alias> auxiliary sys/pwd@<dev-alias>4. Your standby database would be in mount stage and dev in nomount stage.
5. Run the duplicate command
rman>duplicate target database to 'dev' nofilenamecheck;6. Once done, start the MRP on the standby database
alter database recover managed standby database disconnect from session;

HOW? switch from standby database
