Oracle RAC environment

Hi,
I have 4 virtual machines based on XEN. Each of them have Centos 5 OS, 1GB RAM, 10GB disk space. I download all necessary staff for install Oracle RAC, but I wondering what infrastructure I should implement? I want install RAC for test functionality like Cache Fusion, TAF and do some AWR statistic.
What do you think, which choice will be the best:
* raw devices or OCFS2?
* use one xen machine for storage data or partition disk on each machine and use ASM?
* other..
If you have own experience please help me choose best configuration.
Best,
tutus

Hi,
i don't have experience with Xen in oracle RAC but i do use Vmware Fusion on my MAC machine.
** raw devices or OCFS2?*
-- for manageability use OCFS2. raw device is difficult to manage unless you want to try it.
** use one xen machine for storage data or partition disk on each machine and use ASM?*
-- 1. yes you can create a new Xen machine for your storage try considering using Openfiler
-- 2. remember that the disk should be shared on both Linux machine and you cannot just create disk partition on each box.
if you just want to test RAC, why not use vmware its very easy to configure even sharing the disk between nodes.

Calculating total memory in oracle RAC environment

I have to calculate total memry in RAC environment.
For shared and buffer pool I execute show sga.
For UGA and PGA I execute statement that have two different values.
This is my two different methot for calculating total memory in oracle RAC environment.
Why I have very different value in this 2 statements on pga values?
first stat

I'm sorry but it is not clear to me.
- From v$session (1th stmt) I have
nearly 196MB of PGA mem on instance 1
and
nearly 77MB of PGA mem on instance 2
- From v$process (2th stmt) I have
nearly 342MB of PGA mem on instance 1
and
nearly 186MB of PGA mem on instance 2
then...
342+186 - 196+77 = nearly 255MB of memory allocated by oracle processes but free?
if I want calculate the total thing of the amount of the allocated memory from Oracle...It is more correct 2th statement that query v$process...it is true?

How locking take place in oracle rac environment?

how locking take place in oracle rac environment?
Suppose from one session, user is updating and from other session same rows are being selected then how this locking take place in Oracle RAC?

Suppose from one session, user is updating and from other session same rows are being selected then how this locking take place in Oracle RAC?In the case of one session updating and the other selecting, there is no locking issue, regardless of whether it's single instance or RAC.
The update will take appropriate table (TM) and row-level (TX) locks, but the select will not take any locks (unless it's a select for update), so, there should be no problem.
Oracle will use read consistency to guarantee that the selected results are self-consistent and consistent with the point in time of the start of the query.
Hope that helps,

Transaction Recovery within an Oracle RAC environment

Good evening everyone.
I need some help with Oracle 11gR1 RAC transaction-level recovery issues. Here's the scenario.
We have a three(3) node RAC Cluster running Oracle 11g R1. The Web UI portion of the application connects through WLS 9.2.3 with connection pooling set. We also have a command-line/SQL*Developer component that uses a TNSNAMES file that allows for both failover and load balancing. Within either the UI or the command line portion of the application, a user can run a process by which invokes one or more PL/SQL Packages to be invoked. The exact location of the physical to the database is dependent on which server is chosen from either the connection pooling or the TNSNAMES.ORA Load Balancing option.
In the normal world, the process executes and all is good. The status of the execution of this process is updated by the Packages once completed. The problem we are encountering is when an Oracle Instance fails. Here's where I need some help. For Application-level (Transaction Level) recovery, the database instances are first recovered by the database background proccesses and then Users must determine which processes were in flight and either re-execute them (if restart processing is part of the process) or remove any changes and restart from scratch. Given that the database instance does not record which processes are "in flight" it is the responsibility of the application to perform its own recovery processing. Is this still true?
If an instance fails, are "in flight" transactions/connections moved to other instances in the Grid/RAC environment? I don't think this is possible but I don't remember if this was accomplished through a combination of Application and Database Server features that provide feedback between each other. How is the underlying application notified of the change if such an issue occurs? I remember something similar to this in older versions of Oracle but I cannot remember what it was callled.
Any help or guidance would be great as our client is being extremely difficult in pressing this issue.
Thanks in advance

You have not indicated whether you are using TAF or FCF ... that would be the first place to start.
My recommendation would be to let Oracle roll back the database changes and have the application resubmit the most recent work.
If the application knows what it did since the last "COMMIT" then you should be fine with the possible exception of variables stored
in packages. Depending on packages retaining values is an issue best solved with PRAGMA SERIALLY_REUSABLE ... in other words
not using the retention feature.

Disable Intel CPU Hyper threading in Oracle RAC environment

Dear Expert,
Does disable CPU hyper threading will have direct impact or maybe unexpected behavior to Oracle RAC database?
Actually the background of this question is we have many received packet queuing on the network layer waiting to be processed. Investigation leads to the processor utilization which shows that many processor are still in idle state or not used when the other processors are busy processing incoming request.
I have visited some oracle note like
CPU Count Consideration for Oracle Parameter Setting When Using Hyper-Threading Technology (Doc ID 289870.1)
Oracle and Hyper-Threading (Doc ID 205089.1)
Using PROCESSOR_GROUP_NAME to bind a database instance to CPUs or NUMA nodes (Doc ID 1585184.1)
These document already give useful information but i wonder if there is any possibilities risk or another consideration of disabling cpu hyper threading.
Please let me know if any other information required.
Thanks.
Best Regards,
Jolly

As far as I know it is set as cpu architecture and mobile chips don't have the option. Not 100% as I've never needed to do it.
Better bet would be to check Intel ark and forums with them I expect.

A sample server specification for Oracle RAC environment

Hi,
Our project has decided to change the single instance database to a RAC environment. Can any one provide a sample server specification to be analysed based on our project.
For example minimum processor/RAM....

This is the simplest installation you can get, but if you want to do a fast response file based installation, there it is.

Add Dialog instance in Oracle RAC Environment

Hi Gurus,
Do we have to isntall Dialog Instance from sapinst if you want to add a dialog instance in the Cluster Environment?
I want to add two dialog instance to run on node-2 and node-4 using SAPCTL.

Yes, you should run sapinst to install DI.

Are multiple PHYSICAL databases supported in one Oracle 10g RAC environment

Hi alls,
as of Metalink 220970.1 Oracle RAC is also supporting different databases in one cluster installation. RAC handles any resource as a service and it doesn't matter if these services belongs to only one or to different databases. You install the Oracle Clusterware only once and you create any service you want to make high available.
So is technically possible to install multiple databases on same Oracle Rac environment.
My doubts are related to SAP , does SAP certify such environments ?? we could have one SAP R/3 database and SAP BW database co-exist in a single Oracle RAC environment. or also co-exist SAP database with a non-SAP database (an already existing application) in the same Oracle Rac environment.
Any comment would be higly appreciated.
Silvio Brandani

We have ECC, BI, PI and Portal running on same Oracle RAC environment. We have one RAC for QA systems and one for PRD systems. We are not running any SAP applications along with Non-SAP applications on RAC. Keeping SAP and non-SAP apps separate would be a way to go.
Hope this helps.
Thanks,
Naveed

Oracle Upgrade from Oracle RAC 9.2.0.6 to Oracle 10.2.0.4

Hi All,
Currently, we are running 4 node Oracle RAC environment with below mentioned configuration.
OS: Sun Solaris 5.9
Hardware: Sun E2900
Oracle Version: 9.2.0.6
Veritas Cluster Server: 4.1
We want to upgrade Oracle version to 10g, and currently analyzing the options to perform this. The current database size is 1TB appx and we want to spend minimum application shutdown time running on this database.
As part of upgrade, we also need to upgrade Veritas Cluster Server from 4.1 to 5.1 to support Oracle 10g. It would be great help,, if someone can pass some guideline to perform this task.
We are currently thinking about piecemeal approach, where we can upgrade each node individually and then put them back to cluster. There are some complexities involved, and its really high risk approach.
Thanks a lot in advance for help
Regards,
Manoj

Orcale 10g RAC requires you to install Oracle Clusterware. Oracle Supports running it along side a 3rd party clustering software. Not sure why you're so anxious to upgrade Veritas Clusterware when it will be trivial on the 10g db hosts.

Database Table Resource via Oracle RAC connection Manager

Hello,
Our current IDM 8.1 syncs off a HR Database Table using the Database Table connector.
Our DBA's are moving the view into an Oracle RAC environment.
Question: Is there a way for us to connect and sync off our DB table through an Oracle RAC connection manager.
I understand that for the IDM repository, this is possible.
jdbc:oracle:thin@(DESCRIPTION =
(ADDRESS_LIST =
(LOAD_BALANCE = ON)
(FAILOVER = ON)
(ADDRESS = (PROTOCOL = TCP)(HOST = server1.ser.com)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = server2.ser.com)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = db.com)
servers server1 and server2 are oracle connection managers
Thank you for your input,
-RC

We moved the repository to Oracle RAC recently. The syntax to switch to the new databasecluster was something like this:
lh setRepo -tOracle -ujdbc:oracle:thin:@//dbcluster1.domain:1521/service_idm.oradb.domain -Uwaveset -Pwachtwoord
For the 'lh setRepo' command the old database had to be up, and we had to use the old ojdb5.jar. After that we switched to ojdb6.jar.
One of our resources is a database table with HR data in the same database. The following Database Access Parameters work for us:
Database Type:      Oracle
JDBC Driver:      oracle.jdbc.driver.OracleDriver
JDBC URL Template:      jdbc:oracle:thin:@//%h:%p/%d
Host :     dbcluster1.domain
Database: service_idm.oradb.domain
Port: 1521

Configuring our RAC environment Questions

The environment consists of Sun Solaris 10, Veritas, and 10g RAC:
Questions:
I need to know the settings and configuration of the entire software stack that will be the foundation of the oracle RAC environment....Network configurations, settings and requirements for any networks including the rac network between servers
How to set up the solaris 10k structures: what goes into the global zones, the containers, the resource groups, RBAC roles, SMF configuration, schedulers?
Can we use zfs, and if so, what configuration, and what settings?
In addition, these questions I need answers to:
What I am looking for is:
-- special hardware configuration issues, in particular the server rac interconnect. Do we need a hub, switch or crossover cables configured how.
-- Operating System versions and configuration. If it is Solaris 10, then there are more specific requirements: how to handle smf, containers, kernel settings, IPMP, NTP, RBAC, SSH, etc.
-- Disk layout on SAN, including a design for growth several years out: what are the file systems with the most contention, most use, command tag depth issues etc. (can send my questionnaire)
-- Configuration settings\ best practices for Foundation suite for RAC and Volume manager
-- How to test and Tune the Foundation suite settings for thru-put optimization. I can provide stats from the server and the san, but how do we coordinate that with the database.
-- How to test RAC failover -- what items will be monitored for failover that need to be considered from the server perspective.
-- How to test data guard failures and failover -- does system administration have to be prepared to help out at all?
-- How to configure Netbackup --- backups

Answering all these questions accurately and correctly for you implementation might be a bit much for a forum posting.
First I'd recommend accessing the Oracle documentation on otn.oracle.com. This should get you the basics about what is supported for the environment your looking to set up, and go a long way to answering your detailed questions.
Then I'd break this down into smaller sets of specific questions and try and get the RAC axters on the RAC forum to help out.
See: Community Discussion Forums » Grid Computing » Real Application Clusters
Finally Oracle Support via Metalink should be able to fill in any gaps int he documentation.
Good luck on your project,
Tony

Advantages/Disadvantages of installing Oracle RAC on Windows 2003 VS Linux

Hello Guys,
I am not very good with linux, have to create a Oracle RAC environment using dataabse 10g.
I just need to know the advantages/disadvantages of configuring RAC on windows and on linux operating system.
Please help me with this. Please also specify what is the best available windows and linux version to configure RAC.
Regards,
Imran

Go with th eOS you have the skills in, if you have onsite expertise in windows then it makes no sense to use Linux because some guy on the internet says its better. Windows can be a highly available server OS when is managed by professional well quallified adminstrators.
Personally I would use linux because I am more familiar with the OS than windows. I also find oracle makes more sense on a *NIX type platform but there are shops that run oracle on windows with the required high availability.
