RMAN Automatic backup/recovery with oracle fail safe, windows cluster

Hello,
I have question,
1) Whether it is possible to do "RMAN Automatic Backup and recovery" in environment as ?
Environment: -
a. Windows clustering with windows server 2003 Enterprise Edition R2 (Two Node Clustering)
b. Shared disk ( RAID )
c. Oracle 10g standard edition one
d. Oracle fail safe v3.3.3 (for redundancy)
Here we have single oracle instance operating on single database whose files are located on shared disk.
2) If answer to above question is yes please specify if there is some good documentation to it.
Any help regarding this will be greatly appreciated.
Thanks in advance,
Rahul

You just need to make sure that the RMAN scripts are always able to connect to the target database instance whether instance runs on cluster node 1 or cluster node 2
here, If oracle services(resources) will shift from Node1 to Node2 (due to media or any failure) during RMAN Backup then there will be break in connection, will it destroy my backup or will it get started automatically without any harm?
and also I want to know,
Do we need to setup another server which will have RMAN backup script running?

About Note 378648 - Offline backup support with Oracle Fail Safe

Hi forum,
I try to re-post it in Oracle word...
I read note 378648 but I don't understant where I must set the follow variables :
BR_OFS=1
BR_OFS_RESOURCE=< database_resource_name>
BR_OFS_CLUSTER=< cluster_name>
BR_OFS_USER=<user_name>
BR_OFS_DOMAIN=<domain>
BR_OFS_PWD=<password>
I try into init<SID>.sap but without success.
Regards.
Ganimede Dignan.

Those are environment variables of the Windows user who is running brbackup; usually this is SAPService<SID>.
You have to set this variables the same way as you set ORACLE_HOME and so on.
(I am not sure about the details; never worked with MS cluster.)
hope this helps

SAP Note 378648 - Offline backup support with Oracle Fail Save

I am trying to implement SAP Note 378648 - Offline backup support with Oracle Fail Save, but am unsure about part of the solution....
Basically, I have to add several parameters into the Environment Variables of the MS Clustered Servers running Windows Server 2003 for the user xidadm...
Fairly straight forward apart from one parameter....
BR_OFS_DOMAIN=<domain>
I am unsure what is required/meant by domain. Can anyone shed some light??

Oracle fail safe中提示cannot move group

环境平台：
windows 2003 32 bit
oracle fail safe 3.3.3
两个主机加入windows cluster并安装了oracle fail safe
在oracle fail safe manager 中的一个cluster group点选 ‘move to a different node’
提示：the cluster group cannot be moved because is contains oracle service for mscs
觉得奇怪为什么不能move group呢，如果这样不就不能手动作fail over了。
只有在windows的 cluster管理器里面才能做move group的动作。
ps:不知道现在使用oracle fail saf的人是不是很少

可能用windows的人都不多。
我查了资料，cluster group是不能在ofs里面管理的

is this right?
next question
the -cluster flag and the -EM_NODE / -EM_SID_LIST parameters in the emca are only for rac?
with my configuration i can't login to my database over dbcontrol

How to Configure the 10.2 DB Control in a Failsafe Environment
ID: 452305.1
HOWTO: PUBLISHED 17-OCT-2008
In this Document
 Goal
 Solution
 References
Applies to:
Enterprise Manager Grid Control - Version: 10.2.0.1 to 10.2.0.3
Information in this document applies to any platform.
Goal
The goal of the document is to provide the steps to configure the DB Console in an Oracle Failsafe environment.
Please note that the solution offered in this document is not certified by Oracle. It's only provided as a workaround for customers who wish to use this setup for the Database Control Console in a failsafe environment. Support for the procedure outlined in this document will be provided on a 'best efforts' approach.
As an alternative to this approach you can use Grid Control Agents to monitor a database in a failsafe environment. For more details please see:
Note 396659.1 How To Setup Grid Control Central Agent Manually in Oracle Failsafe Environment
We assume the following:
- the database binaries are installed on each node on the local disk
- you already have a failsafe group with the database, the listener, disk resource, and virtual
ip/hostname
Note: This is specific for Windows environments using Oracle Failsafe. For setting up the DB Console in Active/Passive clusters on UNIX please use the following note instead:
Note 362524.1 Configure DB Control 10.2 for use in Active/Passive High Availability Environments
Solution
1. Drop the DB Control repository and configuration files on the active node:
<ORACLE_HOME>/bin/emca -deconfig dbcontrol db -repos drop
2. Recreate the DB Control using the virtual hostname:
- in a command window do the following:
set oracle_sid=<your_sid>
set oracle_home=<your_oracle_home>
set oracle_hostname=<virtual_hostname>
cd %oracle_home%\bin
emca -config dbcontrol db -repos create
-- make sure that the virtual host name was picked up by emca (it will display a summary screen
before continuing)
3. Verify that the DB Console works fine and can be accessed using the virtual host name in the URL
4. Stop the DB Console
5. Create a directory path on the group disk resource similar to your oracle home path on the local disk.
For example:
If the oracle home on the local disk is C:\oracle\product\10.2.0\db_1 and the shared disk is D:
then create the following path: D:\oracle\product\10.2.0\db_1
Copy C:\oracle\product\10.2.0\db_1\<hostname_sid> and
C:\oracle\product\10.2.0\db_1\oc4j\j2ee\OC4J_DBConsole_<hostname_sid>
to D:\oracle\product\10.2.0\db_1\<hostname_sid> and respectively
D:\oracle\product\10.2.0\db_1\oc4j\j2ee\OC4J_DBConsole_<hostname_sid>
Remember to change the values enclosed in <> with those in your environment.
6. Delete the following directories from the local disk
C:\oracle\product\10.2.0\db_1\<hostname_sid>
C:\oracle\product\10.2.0\db_1\oc4j\j2ee\OC4J_DBConsole_<hostname_sid>
7. Create NTFS junction points from the local disk to the shared disk (these work like symbolic
links on UNIX) . It is your responsibility to create these.
You can find a brief guide as well as some tools that will help you create them at:
http://en.wikipedia.org/wiki/NTFS_junction_point
http://www.microsoft.com/technet ... dDisk/Junction.mspx
Important: Please note that this functionality is not certified nor supported by Oracle. Make sure you understand the
implications. Especially don't delete the junction points from Windows Explorer !!
In the end you should have the junction points on the local disk (with the same names as the
original directories) that would point to the directories you copied on the shared disk.
8. Start the DB Console service and verify that everything is still working fine.
9. Stop the DB Console service.
10. Move the Fail Safe group to the 2nd node.
11. Once the database is started, create the DB Console configuration files on the 2nd node:
<ORACLE_HOME>/bin/emca -config dbcontrol db
12. Stop the DB Console
13. Delete the created configuration files from the local disk:
C:\oracle\product\10.2.0\db_1\<hostname_sid>
C:\oracle\product\10.2.0\db_1\oc4j\j2ee\OC4J_DBConsole_<hostname_sid>
14. Create junction points from the local disk to the directories already located on the shared
disk.
15. Start the DB Console service and verify that is working fine.
16. Add the DB Console service as a resource to the fail safe group and put dependencies on the
database and listener services.
17. Perform a fail over and see if everything works fine.

Logs for Oracle Fail Safe

Hi Guys
I need to know where Oracle writes logs for Fail Safe components, Fail Safe Manager and Fail Safe server?
Any idea?

PG

First of all, I'm not a native English speaker, so excuse for my msitakes :8}
I have a basic knowlede of Oracle, but this is something I need help with:
I have a Windows cluster with Oracle Fail Safe. There will be multiple databases on this cluster. Oracle and Oracle Fail Safe are installed on disk D: on both nodes (local disk).
When Fail Safe creates a sample database it creates this directory structure on cluster disk O:
OFSDB
OFS1
admin
OFS1
adump
bdump
cdump
pfile
udump
flash_recovery_area
OFS1
ONLINELOG
oradata
OFS1
{code}
All database related files like parameter files are created on the cluster disk, not in Oracle Home, where they are by default.Hi
most of the directories that you refer to are controlled by initialisation parameters in the parameter file for the database. What would probably be sensible for you to do is to use DBCA not to create the database, but to create the scripts to create the database. You can then edit those scripts appropriately.
In particular the directories used in your example are controlled by these parameters
adump                           audit_file_dest
bdump                           background_dump_dest
udump                           user_dump_dest
cdump                           core_dump_dest
flash_recovery_area         db_recovery_file_dest (and db_recovery_file_dest_size)the online log directory tree will be created if you choose to use oracle managed files for the redo logs, alternatively you can manually specify them in the create database statement.
The generated scripts should contain a .bat file which precreates the admin structures.
so to recap, use dbca to create the scripts :- edit the scripts, don't set ORACLE_BASE.

Oracle fail safe real time users

hello,
Please let me know about some oracle fail safe users
Thanks in Advance,
Rahul
Edited by: user10911629 on Jun 2, 2009 1:51 AM

hi rahul,
i think i have sent you some links and documents for oracle fail safe case studies...haven't they of any use?
you can refer oracle docs and can raise the SR with oracle support if you come across any issue and disaster recovery situation....
please check the documents i have given to you
and rather looking for customer case studies you should look for oracle fail safe specific doc as it is recommended by oracle, client or customer may adjust oracle fail safe architecture according to their environment, but oracle docs insist you to make environment required for oracle fail safe.
have a look for this oracle case study

Converting Single Instance database into Oracle Fail-Safe on Linux

Hi All,
We have single instance Oracle10g database running on Linux RHEL4. We are looking to convert this database into Oracle Fail-Safe (Active-Passive). Does any one have document for Oracle fail-safe setup?
Regards,
Tushar

Tushar,
you can't use software for windows on Linux.
However, there's number of ways to implement high-availability solution on Linux Oracle.
You can go with Active-Active (RAC) - which means that you'll have two servers attached to the same database at the same time. You can use either, and if one goes down(due to power failure for instance), the second will still be available.
You can go with Active-Passive (Data Guard) - which means that you'll have one of the nodes being active and the second passive, but synchronized with the first one, so in case of failure of the first node you can activate the second one.
You can also go with linux clustering - which is most similar to MCS + fail-safe - you'll have two nodes clustered with linux clustering software (RH cluseter suite for instance) and connected to shared storage. One node is active, and in case of crash database instance will be automatically started on the second node. This is beneficial because you can use your resources more efficiently. In case if you have two databases you can run each of them on dedicated server and then, in case of node failure move to another one. However, the setup of such configuration is quite cumbersome.

Error in Creating the Oracle Fail Safe Group during installation on MSCS

Hi All,
I am installing ECC 6 dual stack on MSCS.
I have done steps till CI installation as per installation guide.
I am gettig the following error in the step "Creating the Oracle fail safe group" while changing physical hostname into the virtual databse hostname using configtool in secure store parameter jdbc/pool/<SAPSID>Url as per the installation guide.
"Error occurred while working with configuration(scanning)
MSG:Error while connecting to the database"
I think it is not accepting the virtual hostname.
In our scenario CI is running CI node and DB instance is running on DB node.
I have followed the steps as per the installation guide.
Please let me know how to resolve this issue.
Database - Oracle 10g,OS is Windows server 2008 enterprse edition.

Hi,
Thanks for your reply.
1) did you stop the CI before making the modifications as stated in the installation guide?
 Yes
2) is your database currently running on the same physical cluster node as your CI?
 No.Database instance is running on DB node and CI is on CI node.
3) is your database online?
 Yes,it is up and running
Please let me know if there is anyway to resolve this issue.

Win 2003 Cluster + Oracle Fail Safe + Dataguard (physical & Logical)

Hello, 
 
It´s my first post (sorry for my bad english)...I am mounting a high availability solution for test purpose. For the moment i mount the following and runs ok, but i´ve a little problem with the logical database: 
 
Configuration 
ESX Server 2.0 with this machines: 
Windows 2003 Cluster (Enterprise Edition R2, 2 nodes) 
* NODE 1 - Oracle 10gR2 + Patch 9 + Oracle Fail Safe 3.3.4 
* NODE 2 - Oracle 10gR2 + Patch 9 + Oracle Fail Safe 3.3.4 
c:/Windows Software 
e:/Oracle Software/ (pfile -> R:/spfile) 
 
Virtual SAN 
* Datafile, Redos.. are in Virtual SAN. 
R:/ Datafiles & Archivers & dump files & spfile 
S:/ , T:/ ,U:/ -> Redos 
V:/ Undo 
 
Data Guard 
* NODE3 Physical Database 
* NODE4 Logical Database 
 
The Oracle Fail Safe and windows cluster run OK, the switchs... 
The physical database runs OK... (redo aply, switchover, failover, all ok) but the logical receives the redos ok but it has a problem when goes to apply the redo. 
 
The error is the following: 
ORA-12801: error señalizado en el servidor P004 de consultas paralelas 
ORA-06550: linea 1, columna 536: 
PLS-00103: se ha encontrado el simbolo "," cuando se esperaba uno de los siguientes:

update "SYS"."JOB$" set "LAST_DATE"=TO_DATE('11/09/07','DD/MM/RR'), 
 
This sql statement i saw in dba_logstdby_events and was joined with the error in alert log and dba_logstdby_events. 
 
I´m a bit lost with this error. I don´t understand why the logical database can´t start to apply the redos received from primary database. 
 
The database has two tables with two columns one integer and the other a varchar2(25). She hasn´t rare types of columns. 
 
Thanks a lot for any help, 
Roberto Marotta 

I recreate the logical database OK, no problem, no errors. 
 
The redo aply run ok. I have done logfile switch in primary database and they were applied in logical and standby databases. But... 
 
When I created a tablespace in primary database when i did a switch logfile in primary the changes transfers ok to standby database, but to logical NO!!!, the redo are in they path in logical ok, but when the process tried to apply, reports me the same error.

The alert.log report the same message that the dba_logstdby_events view. 
 
Any idea¿? 
 
I´m a bit frustrated. It´s the third time that recreate the logical database OK and reproduce the same error when i create a tablespace in primary database, and i haven´t got any idea because of that.

How to configure OEM for a database which is under OFS(Oracle Fail Safe).

Hi,
We have customer who is using database 11g and also using OFS(Oracle Fail Safe) for switching to other machine if there is any problem with current machine. So how to configure Agent in this scenario.
What i have done is i have installed the agent on node1 and configured to monitor the database. it is monitoring properly. no issues.
But when database started from node2, here agent will not be there. Do i need to install the agent on node2 as well. Thanks in-advance for your support.
Regards
DBA.

Hi,
You need to a script and run it on os level. Here is an example:-
emcli relocate_targets -src_agent=agentmachine1.domain:3872
-dest_agent=agentmachine2.domain:3872 -target_name=RACDB
-target_type=oracle_database -copy_from_src -force=yes
-changed_param=MachineName:agentmachine2.domain

Regarding Oracle fail safe

Hi,
We have to use Oracle fail safe in our environment (windows server 2003 R2 64 bit with Oracle 10g 64 bit).
Please if anybody have doc for this please provide and which version will be compatible.
Regs,
Brijesh

Hi Brijesh,
I used Oracle fail safe for Oracle AS 10GR2 and for Oracle 9iR2 Active / Passive cluster. Most of the documentation is provided by Oracle, and yes it helped me a lot to configure the setup. The links provided by Helios are sufficient for this.
May be you should refer this Doc as well from Oracle Metalink - Oracle Support
1) "Oracle Fail Safe Frequently Asked Questions : General Doc ID: Note:60787.1 "
2) "Oracle Fail Safe Step-By-Step Installation and Configuration Doc ID: Note:74009.1"
