New To Rac 11g

Hello,
I am new to RAC and i need some guidance here. I will be responsible to set up RAC on the servers which i think i should be able to manage. My concern is that since i'm new to RAC i would need to refer to some quick material on how to manage RAC instances e.g startup/shutdown nodes , maintainence , backups etc..
Could some one give me a place where i could refer to really quick on how to manage RAC rather than going through in depth oracle documentation, which i surely plan to go through in the future. I need something really quick to get started.
Thanks in advance for all the help

Oracle RAC 11g query

Hi All,
I am new to Oracle RAC 11g, facing a issue, Request all to help.
1) What is the instance id means which we get from gv$session in Oracle RAC setup?
2) What is differnce between Session failure and node failure?
3) If session fail, then client should connect to node1(to which session previously connected) or node2?
Thanks

1) What is the instance id means which we get from gv$session in Oracle RAC setup?Instance ID is unique for each instance in clustered database.
2) What is differnce between Session failure and node failure?Session Failure - when the connection to an instance is lost, SESSION failover results only in the establishment of a new connection to another Oracle RAC node
Node Failure/Eviction - we can say hardware fails, the Cluster Manager reports the change in the cluster's membership to Global Resource Directory (GRD)
Resource directory which consists of both Global enqueue service & cache service
3) If session fail, then client should connect to node1(to which session previously connected) or node2?You have to configure in SERVICE.

Oracle RAC 11g R1 Release Connection Failover Problem

Hi All,
In our Architecture we are using Oracle RAC 11g R1. Below is the JDBC URL :
JDBCURL = jdbc:oracle:thin:@(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = Host1-vip)(PORT = 1521))(ADDRESS = (PROTOCOL = TCP)(HOST = Host2-vi
p)(PORT = 1521))(LOAD_BALANCE = ON)(FAILOVER=ON)(CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME = <Service_name>)))
We are using two node RAC. The problem is whenever we are rebooting a Node and rejoin the cluster, Application Servers are not able to recognize that.
Suppose we have node1 and node2, I will take down node1 (freeze the cluster) and then reboot node1 and bring it back up( and join the cluster). At this point, My application servers are not able to recognize that some new DBserver(node1) had joined the cluster until I restart my application servers.
Please Provide me a solution for this. Thanks alot to everyone in advance.

Oracle rac 11g installation

Hi
Am planning to install oracle RAC 11g on linux server. Have doubt on installation of clusterware or grid infrastructure first .?
I think grid infrastructure covers clusterware and ASM both and then oracle 11g software to be installed.
But how to download grid insfrastructure software. Will it come with oracle 11g software..? or need to download it seperately.?
Because when i try to download oracle RAC 11g which gives link to download the 11g software not grid.
Thanks in advance,

Hi,
Its called "oracle one node rac" you will find plenty of documents on metalink, extract is below, hope this helps you to understand the differences.
Oracle RAC Database : Oracle RAC database is a clustered database. It can have more than one instance running on one or more hosts. To make is database RAC , there is another software needs to be installed called Oracle Grid infrastructure which takes care of multinode sync, ASM, Oracle restart etc. Oracle GI is necessary as a base of Oracle RAC. In Oracle RAC, the load is balanced across multiple instance of databases running on different nodes. This is best for Production database. Failure of any instance is abstracted from user and forwarded to another instance from the database server pool. No of instances can be controlled using Policy Managed or Admin Managed.
Oracle RAC One Node : Some time we need to have RAC databases but donot need many instances, why? Simple answers to it is leverage the high availability of RAC. The Oracle RAC One node is a RAC DB runs on one host. The advantage is it saves your resource, can to converted to full RAC any time, Cluster fail over i.e. the Database instance is moved to new instance in case of any failure on host known as Instance Relocation,easy to upgrade etc. This type of database is well suited for small production and dev/test environments.

Need Document/Steps for Cloning RAC 11g.

Hi,
I am looking for a document to clone an existing RAC 11g database.
I believe in the cloning process this will create a new RAC database...
Also the source database data has to be applied to the cloned rac db.
Environment 11g, AIX.
Advice needed.
Thanks in advance.

Hello Indigo,
The steps are necessary,
1) Create the password file
2) Create the spfile for the DESTINATION database (auxiliary database)
3) Create the necessary mount points or the folders for the database files
4) Execuute this command from the primary database.
DUPLICATE TARGET DATABASE TO <standby_name>
FOR STANDBY
FROM ACTIVE DATABASE
SPFILE
PARAMETER_VALUE_CONVERT '<string>', '<string>'
SET DB_FILE_NAME_CONVERT '<string>', '<string>'
SET LOG_FILE_NAME_CONVERT '<string>', '<string>'
SET SGA_MAX_SIZE 1000M
SET SGA_TARGET 850M;
Please see the *11g : Active Database Duplication ID 568034.1*

Oracle RAC 11g on Windows 2008 64 bit - blue screen error on both nodes

Hi Everyone,
I installed Oracle RAC 11g on Windows 2008 64 bit, The installation was successfull and crs_state -t shows all services in two nodes are online.
When executed a select query with 100 sessions( For performance evaluation using Transaction generator ) ,the machine got crashed and blue screen is appeared on two nodes. I restrated the machines and and starts the same evaluation ,bt the same bug is repeating.
Can anyone suggest a solution to solve this issue? Is our hardware is not sufficient ? Shall we need to perform any
specific settings in Oracle RAC setup for performance evaluations?
Is our settings for load balancing is not enough? ( We added "Load Balancing= On" on tnsnames.ora on client for load
balancing)
The following machine configuration is used for Oracle RAC setup
Intel Core 2 Duo 2.66 GHz,
Ram :4GB.

Please reply soonYou know that the modifications you'have done on spfile are not active until you restart DB. So why don't you want to modify the spfile by "alter system ... scope=spfile" commands? I don't see the point to create pfile, modify it and recreate spfile...

Error during installation Oracle RAC 11G

Hi experts;
I'm installing Oracle RAC 11G, this installation will be in two virtual servers, OS Linux redhat.
I began the installation with these steps
Configure Security Updates
then ask for proxy server information (nothing was entered), continue
Installation Option (don't ask anything)
then System Class (Server class selected)
Grid Options
(Real Application Clusters database installation)
when hit ENTER I got this errror message - (INS - 35354) The system on which you are attempting to install Oracle RAC is not part of a valid cluster.
I was looking in some forums an I found one where indicates I should indentiify these files and change some info on them;
=============================================================================
cat /etc/oraInst.loc
The ouput of the above command lists the inventory_directory
Browse to the inventory.xml file in that directory. My oraInventory
cd /u01/app/oracle/oraInventory/ContentsXML/
cat inventory.xml
You can verify that the flag CRS=true isn’t set for the $GRID_HOME
==============================================================================
However, I couldn't find any of those files in my directories.
also, i was verifying the note [ID 1053393.1, but again, I couldn't find where to change the values for CRS.
Any idea what I'm doing wrong?
I will apreciate your help.

Hi,
RAC is a database in a cluster. One Database opened by one o more instances in one or more hosts.
Note: RAC is not a cluster, but a Database cluster.
To allow database be clustered, we need to install a software cluster.
We have some options, but Oracle developed your own software cluster actually named Grid Infrastructure for a cluster AKA Oracle Clusterware.
To install RAC you need first install and configure your cluster.
Before you start install Oracle cluster/RAC I recommend you start with concepts.

Oracle client 9i and Oracle RAC 11g

Hi,
Would appreciate to help me in following. I have installed RAC 11g on one site and on another site I have machine with installed client 9i. All traffic between them going through firewall.
Client is using by application that opening from 8 to 12 sessions to server with permanent high load. Periodically we are getting error "end-of-file communication" that means disconnections with DB.
Can it be compatibility issue between 9i client and 11g server or most probably firewall killing connections?
On the same site that installed DB, we are using 11g client and there everything working perfectly. So it can be only firewall or client 9i issue.

My version of client is 9.2.0.7. It should be compatible as per this doc:

ORACLE_HOME in Oracle RAC 11g (Windows Server 2008)

Hello,
I've got two (2) nodes in an Oracle RAC 11g in Windows Server 2008. Oracle software is installed in C:\app.
I realized that it's not been set ORACLE_HOME path. In System Properties-> Advanced -> Environment Variables, I see that ORACLE_HOME is empty.
- Which path would be the ORACLE_HOME: C:\app\bd\product\11.2.0\dbhome_1
- Do you have to setup the same in both nodes?
Thanks

I realized that it's not been set ORACLE_HOME path. In System Properties-> Advanced -> Environment Variables, I see that ORACLE_HOME is empty.its normal behaviour
- Which path would be the ORACLE_HOME: C:\app\bd\product\11.2.0\dbhome_1if you installed that location, yes
- Do you have to setup the same in both nodes?actually, you dont HAVE TO, its not needed at all
