Steps to switchover a standby to production

Hi All,
How can I perform a switchover from a standby database to production and vice versa.
Thanks in advanced
Bhupinder

Metalink has few good notes on this subject. In case, if you dont have any access to metalink, here is a good PDF.

Steps To Create Physical Standby Database In Windows 7

Hi All,
I want to create a physical standby database in my windows 7 system. I have created one service stdby in my machine with all your help and now I need your help to configure standby configuration.
I am using Oracle 10G version 10.2.0.1.0.
Please suggest.
Regards,
Arijit

[on primary]
step-1 check if archiving is enable
SQL> archive log list;
Database log mode              Archive Mode
Automatic archival             Enabled
Archive destination            /PGHProdDB/archive/paceview/
Oldest online log sequence     52
Next log sequence to archive   54
Current log sequence           54
step-2
sqlplus> ALTER DATABASE force logging;step-3
connect to rman
take an full backup
RMAN RUN {
allocate channel d1 type disk;
backup format '/u01/backups/PRIMARY/df_t%t_s%s_p%p' database;
sql 'alter system archive log current';
backup format '/u01/backups/PRIMARY/al_t%t_s%s_p%p' archivelog all;
backup current controlfile for standby format '/u01/backups/PRIMARY/sb_t%t_s%s_p%p';
release channel d1;
step-4
now copying initpfile,pwdfile on appropriate destination and rename it.
step 5
now create listener on standby db side::
and restart it by ----
lsnrctl reload
and login to primary db and register listener information in tnsfile.ora---
standby=
(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.13)(PORT = 1521))
    (CONNECT_DATA =
      (SERVICE_NAME = standby)Step 6 Startup the standby
SQL> startup nomount pfile='/u01/app/oracle/admin/PRIMARY/pfile/init.ora';step 7
though our primary db is ready to connect with standby db
[oracle@PGH-DB ~]$ rman target / auxiliary sys/tiger@standby
Recovery Manager: Release 10.2.0.4.0 - Production on Mon Aug 6 12:16:08 2012

connected to target database: primary (DBID=2092349485)
connected to auxiliary database (not started)
RMAN> run {
allocate channel C1 device type disk;
allocate auxiliary channel C2 device type disk;
duplicate target database for standby nofilenamecheck;
}When this completes
Make sure you shutdown the database and then switch the ORACLE_SID=STANDBY
when you perform that much let me know :)

Propagation after switchover to standby

Hi
My DB Version=10.2.0.4
I had a stream relation that working correctly after switchover to standby in destination now in source database i got the following error in propagation:
select status,error_message from dba_propagation
DISABLED
ORA-02068: following severe error from AQHOS
ORA-01033: ORACLE initialization or shutdown in progress
ORA-06512: at "SYS.DBMS_AQADM_SYS", line 1087
ORA-06512: at "SYS.DBMS_AQADM_SYS", line 7616
ORA-06512: at "SYS.DBMS_AQADM", line 631
ORA-06512: at line 1
i corrected all tnsnames and dblink is working correctly but still i have this error.
WHAT I MUST TO DO?

Refer to metalink document _STREAMS propagation to Primary of physical Standby configuation errors with Ora-01033, Ora-02068 *[ID 359971.1]*_
You need to set SERVICE_NAMES. Hope this helps resolve your issue.

After switchover to standby as primary, now how to switch back

Hello DG experts:
I'm running Oracle 11.2 on Linux 5.8.
I am in the process of (trying) to mimic our existing production DG environment for testing purposes.
So far...
I've managed to set up a primary and standby database and ensured all logs apply properly.
My database name is DGTEST (on both primary and standby).
My db_unique_name is DGTEST_DG1 on primary, and DGTEST_DG2 on standby.
I performed a switchover from primary to standby, and opened the standby database as primary.
But, first thing is that when I check the switchover_status from v$database, it says: NOT ALLOWED.
Okay, so now what? Do I need to have another pfile to set specifically for when I am in primary or standby modes?
Here are relevant commands I have checked already:
on new Primary (db_unique_name = DGTEST_DG2)
SQL> select switchover_status from v$database;
SWITCHOVER_STATUS

SQL> select sequence#, applied from v$archived_log order by 1;

                                 . . .Please keep in mind that I have made this test environment as close as possible (I think) to our production environment.
One of the objectives is to confirm we can switchover and back in our production environment.
So if there is something seriously wrong with this environment and it is the same in our production environment, that would be one of my primary objectives to find out about.
Only significant difference is that we are also using DGBroker in production and I did create configuration yet until I got the switchover working manually first.

you have now two different pfiles: one in c:\temp\initstdby4.ora. and %ORACLE_HOME%\database\initstdby4.ora.
You are using the latter, as you didn't specify pfile= in your startup mount.
Also, if you are using a spfile, the only line in a pfile should be: spfile=....
In your pfile you are mixing up Unix like file locations with \ and Windows file locations with /
Could you please read the docs

Switchover in Standby database.

Hi All,
DB:11g
OS:AIX
If I am performing a switchover for a Physical standby database, and I have successfully converted my Primary database to new Standby database and when I am trying to convert my Old Standby database to a new Primary database and let us say due to some error (the error is not the important here) I am not able to switch my Old standby database to a new primary database.
What should be my possible steps to undo the switchover or to get me out of this hole?
Regards,
Sphinx

Hi Mohamed,
Thanks!
Well, I was asked this question in an interview and I cross questioned him "What is the error?". He said that the error is irrelevant and you have to give me back a Primary database in minimum time.
Since the original primary is now converted to a standby database and the old standby database is not getting converted to Primary database, so what steps I will have to do to get a Primary database in minimum time, at this moment even if I do not have a standby database that will do as per the interviewer.
This is my concern, finding the error is secondary which I can dig once my Primary is back.
In a nutshell, I just want to know if in the middle of a switchover that I have to perform in a time constrain, if my switchover fails as I have explained above. What approach or steps that I have to take to undo the swicthover or at least get my Primary back.
Hope it calirifes.
Regards,
Sphinx

Steps to create the standby with Hot Backup........?????

Hi All
I am planning to create the Physical standby with Hot backup ....
Can anyboby give me the link/steps which explains how to do this?
Thanks
Gagan

To copy the file from the primary, you can use RMAN, or manual hot backup copy with begin backup and end backup mode.
You can read the doc about creation of standby database :

Installing Flash player doesn't finish Step 3 Prompt to buy another product

Installing Flash player, after completing Step 2, I'm prompted to buy other products, which I don't want to do. Anybody have a link that actually completes all steps? Safari browser is not loading pages. Need help asap. Thanks!

You don't need to buy anything to finish the Flash Player installation.
Please use the offline installer:
http://fpdownload.macromedia.com/pub/flashplayer/latest/help/install_flash_player_osx.dmg
If that's not working, do you have any add-ons (Adblock Pro, etc) that might be preventing Flash Player from starting?
If not, sometimes Safari gets confused (particularly if it was blocking an outdated version of Flash). Doing a complete uninstall/reinstall of Flash Player typically solves it.
Uninstall Flash Player | Mac OS
Then just run the offline installer above again.

Customization step for in New Plant in production planning.

Dear Experts,
Thanks for your continues support from SCN.
My company having one of the production process unit.
Already some plants (1000 ) are assign the process order customization. But currently include one additional plant ( 1001) for process manufacturing.
Basically create order type, production scheduler, production scheduling profile these are all the main thing, other wise what are all the assignment to be ensure , create and followed.Kindly send me the customization step for each assignment in our new plant.
( order creation to end of the account settlement itself)
I am waiting for your valuable feedback.

Hi Anil,
if all master data configuration is over in the new plant, you can proceed to crteate the required cofiguration for new plant.
if your production process is similar across all plants then you can simply copy all the required things from your old plants, or if the process is different in the new plant you have to configure the required settings.
as you asked what are required settings apart from Basically create order type, production scheduler, production scheduling profile these are all the main thing,
apart from above things. actually the configuration is depends on your Production process which you Follow in your business. as standard process starts from Configuration od SOP And Transfering Demand To MRP and Running MRP then executing the results of mrp in this case we need to configure SOP And MRP Settings First then remaining Production process configuration.
can you give the details of your PRoduction process then we can discuss the sequence of required configuration.
Thanks&Regards,
Venkat.

Data Guard - Steps to install Physical standby database in an RHEL 5.6 x86

HI Team,
I need to install Physical standby database in a OS installed from factory with most basic packages. Please find the info in detail
Standby Server :
Database Version : 10g Release 2
Operating System : Red Hat Enterprise Linux Server release 5.6 (Tikanga) , RHEL 5.6 x86_64
swartis.dc$ free -m
total used free shared buffers cached
Mem: 34158 33847 311 0 558 28367
-/+ buffers/cache: 4921 29237
Swap: 10001 63 9937
- Things i need to validate in the PROD server. Eg : Are the prod db version & standby db version should be the same, Do the OS need to be same ............ETC
- Basic Linux rpm required for standby server & any other pre-requisites required at standby server
- Verify connectivity speed btw servers to decide log file size
- Please give me more detailed steps , where i need to start the steps in installation of Physical standby database.
Thanks in advance.

Hello again;
Sorry for the Delay.
To this question "Do i need to install 10.2.0.2.0 ORACLE_HOME & on top of it apply 10.2.0.3.0 patchset.?"
Yes.
All my Oracle 10 installs started with 10.2.0.1 and then I patched up from there. If I remember correctly 10.2.0.1 may bark on Red Hat 5.
You can work around this by reviewing this file :
/etc/redhat-releaseSave whatever is in there somewhere and replace it with :
redhat-3After the install put back what was there and get rid of the "redhat-3".
I extra RPM's I used were :
rpm -ivh kernel-headers-2.6.18-164.el5.x86_64.rpm
rpm -ivh compat-libstdc++-33* libaio-devel*.x86_64.rpm
rpm -ivh elfutils-libelf-devel*.x86_64.rpm glibc-devel-2* gcc-4*.x86_64.rpm gcc-c++-4*.x86_64.rpm libstdc++-devel-4*.x86_64.rpm glibc-headers*.x86_64.rpm libgomp*.x86_64.rpm
rpm -ivh compat-libstdc++-33* libaio-devel*.x86_64.rpm
rpm -ivh sysstat*I searched my Red Hat Disks before hand and ran the RPM commands as shown. Adjust as needed.
To verify that the required packages have been installed on your system, run the following command :
pm -q --queryformat "%{NAME}-%{VERSION}-%{RELEASE} (%{ARCH})\n" binutils \
compat-libstdc++-33 elfutils-libelf elfutils-libelf-devel gcc gcc-c++ glibc \
glibc-common glibc-devel-2.5 libaio libaio-devel libgcc libstdc++ libstdc++-devel \
make sysstatThis document is for Oracle 11, but the OS part should be the same.
http://www.visi.com/~mseberg/installing_oracle_11g_r2_64.html
Currently I have 3 servers running both Oracle 10 and 11 ( In different homes ) using this OS.
I have used Oracle 11 document with Oracle 10 also : ( Better once you are setup and a great standby recovery document )

How to Refresh UAT Primary/standby from Production primary/standby

Hi ,
We have the following setup :
Primary/standby - Production
Primary/Standby - UAT
I need to know the process on how to refresh the UAT primary/standby .
I'm thinking on the following lines :
1] If we have the export dump of production , can we go ahead and drop the schemas to be refreshed on both UAT Primary and UAT Standby UAT then perform the schema import on Primary UAT .
2] In case if I have to do a full refresh of UAT , do I need to rebuild the UAT environment from the proudction backups Ie,
(i) Drop both the UAT primary and UAT standby database .
(ii) using the produciton backup built the UAT Primary . Take the UAT primary backup and build the UAT standby .
Appricaite if any one can provide some best practices to refresh UAT from Production.

That setup seems to be rare. We assume that the Standby Database is used for testing and have a feature for that called Snapshot Standby.
But in your scenario, you need to develop your own techniques for "refreshment of the UAT Primary".
An easy way (if your Primary is not too large): Throw away your UAT env each time the "Production Primary" changes and RMAN clone it to "UAT Primary" then.
Then RMAN duplicate "UAT Standby" again. Could be relatively easily scripted.
But again: Why not just create an ordinary Standby on your UAT hardware and use it for testing with Snapshot Standby feature? Much easier to maintain.
Kind regards

Switchover to Standby is it necessary to shutdown other nodes?

Hi,
I have installed oracle 11g r2 rac with asm in two nodes. OS is hp-Unix.
I have installed oracle11g Active Data Guard using Single alone Database.
Both RAc and Active Data Guard works fine.
I have not configure Data Guard Broker.
For testing purpose I need to make primary as standby and standby as primary.
In node 1: I will run commend in node 1
SQL> ALTER DATABASE COMMIT TO SWITCHOVER TO PHYSICAL STANDBY WITH SESSION SHUTDOWN ;
Shall I need to shutdown node 2 in RAC?
if node 2 is in shutdown then after switch over primary as standby just open the node 2 ?
Thanks

if node 2 is in shutdown then after switch over primary as standby just open the node 2 ?When you are not managing with broker, primary if you have 2 node RAC. Then prior to switchover shutdown any one of the node.
Once you performed switch over, Your primary database will be non-RAC database[because not an clustered], So the redo threads active in only one node.
In such case you will be having one node primary and one node standby.

Switchover logical standby dataguard

hi
we are using oracle9i on enterprise linux 3 . our primary and logical database are not located remotely but are two different servers.
now i need to know the steps that i need to perform in order to switch my primary database to standby database and vice versa . i tried few things but was unsuccessful.
according to my concept what we need to do is
Make sure no data is arriving and the applied and newest_scn are equal.
change the database role of the respective database .
make changes in initialization parameter file to change the primary dest as standby and vice versa .
and then start logical standby apply .
Is thier something that i am missing i tried few things from net but was not able to understand the logic and was unsuccessful .
THANKS

Physical Standby to Production

I am running my production database on Oracle 9iR2 on windows2003. I have also got a standby database of this production on another machine.
I want to shutdown my production and make the standby database live as a produciton, how would I do that? Please guide. I am not using DataGuard.
Thanks and regards,
Fahd

Thanks for the reply..
I have checked the readme file it is not of much help. I shall be greatful if you can provide something else other than README file.
Thanks
