Required hardware for a oracle real application cluster
hello i´m a newbie and have a question:
We want to migrate a DB2 database to Oracle database. This database will run in the cluster network. What hardware do I need a prerequisite to set up an Oracle Real Application Clusters (10g)?
thank a lot for help!
Hi,
HW sizing depends on lot of information like the Size of the Database, Average load on the Database, Number of DB users, what application is using the database... could you please let us know all these information and oracle license depends on the number of CPU you on the server. Kindly let us know the OS on which you want to run the oracle RAC.
Regards,
Satya.

Configuring Oracle Real Application Cluster
Hi,
Is it possible to configure Real Application Cluster (RAC) Oracle 9i with Windows 2000 Server / Advanced Server ?
If yes, what component and Oracle Software should I prepare to build this system ?
Can anybody explain this step by step.
Thanks in advance
ESBHi;
For your issue i suggest close your thread here as changing thread status to answere and move it to Forum Home » System Management and Integration » Data Integrator which you can get more quick response

Oracle real application cluster test case
Hello everyone! I have just finished implemented oracle real application for customer. Now I need to do UAT for them with cases. Some of the cases I am not sure whether it can make the cluster fail, or need to repair, or unrecoverable. I need to tell them what is happening if sth go wrong as the following cases:
case 1. connection from database server to storage is down in one node, or all node in the cluster.
case 2. private connection down
case 3. public network down in node node or all nodes in the cluster.
Please, help address the status and behavior of oracle rac, or suggest me some useful document regarding this cases.
I'll appreciate your help.
ThanksHi,
How about here site -> Oracle Clusterware

If you learned about voting disk is good.

How to connect to Oracle "real application cluster" RAC?
Hello,
I don't know how the dbUrl-Parameter should look like to connect to an Oracle RAC.
normally I use:
jdbc:oracle:thin:@(Server):(port):(servicename)
e.g.:
jdbc:oracle:thin:@frxxx7....world.com:1521:kfics
but what should I use if I want to connect to an RAC? In this case I don't have a single server?
Thanks for your help.
Regards.
MatthiasHello again,
I found out half of the solution.
Normally you use a serverUrl like:
jdbc:oracle:thin:@(DESCRIPTION=(LOAD_BALANCE=on)
(ADDRESS=(PROTOCOL=TCP)(HOST=host1) (PORT=1521))
(ADDRESS=(PROTOCOL=TCP)(HOST=host2) (PORT=1521))
(CONNECT_DATA=(SERVICE_NAME=service)))
normally you can also add other information like failover_mode etc.
BUT: MII (12.0.6) only alows a string of 200 characters. Here is a part of the error-log:
Exception of type com.sap.sql.log.OpenSQLException caught: Cannot assign a java.lang.String object of length 309 to host variable 3 which has JDBC type VARCHAR(200)..
so if I have more than two servers or additionally information for failover_mode etc. I'm not able to use the oracle RAC, because the serverUrl is too long.
Any suggestions?
Regards

Real Application Cluster on Sun Solaris 8 and Sun Cluster 3
Hello,
we want to install Oracle 9i Enterprise Edition in combination with Oracle Real Application Cluster-Option on 2 Nodes. Every node (12-CPU-SMP-Machine) should running Sun Solaris 8 and Sun Cluster 3 Service.
Does this configuration work with ORAC? I found nowhere informations about. Is there anything I have to pay special attention for during installation?
Thank you for helping and best regards from Berlin/Germany
Michael WuttkeForms and report services work fine on solaris 8.
My problem is on the client side.
I have to use solaris 8 with netscape like forms clients

What is Oracle 10g Release 2 Real Application Cluster?
Hello Guys,
I have been working in Oracle database 9i for last 2 years. Just using the simple features of oracle. Now our data have grown and company wants to enhance the database version and also want to perform load balancing at oracle's end.
Have heard a lot about Oracle RAC, but i am not sure what actually is oracle rac and its installation.
What is the difference between Oracle 10g Release 2 Enterprise Installation and Oracle 10g Release 2 Real Application Cluster installation. Are these 2 different softwares available on different CDs or RAC is only a different way to install oracle 10g database in RAC mode.
Please clerify and explain. Sorry this is a very beginner level question but i want to learn it and implement it.
Regards,
Imran BaigWhat is the difference between Oracle 10g Release 2
Enterprise Installation and Oracle 10g Release 2 Real
Application Cluster installation. Are these 2Enterprise Edition is the database management software provided byu Oracle.
RAC is an extension to the Standard and Enterprise Edition to permit the same database to be managed from two or more computers. (Withe Enterprise Edition, it is an extra cost option. With Standard Edition, it is included in the price, since SE has other limitations.)
Conceptually, RAC is simple - IF you understand the difference between Instance and Database. RAC = 1 database managed by many instances
Physically, RAC requires a healthy investment in infrastructure - the infrastructure and the RAC software addresses the question: how do you get several computers able to read and write to the same disk and the same block without data corruption?
If you are serious about RAC, take a course. If you are in the US, consider http://www.psoug.org as an 'Intro to RAC' course provider. -
Newbie question about Oracle Parallel Server and Real Application Cluster
I am trying to find out what kind of storage system is supported by the 9i Real Applicaton cluster. I have looked at the 8i Oracle Parallel Server which requires raw partitions and therefore NAS (network attached storage) that provides an interface at the file level will not work. Does anyone know if the 9i Real Application cluster has a similar requirement for raw partitions? any suggestions of whether SAN or other technology will be suitable? pointers to more information is appreciated.
RobertHi Derik,
I know this is a really broad question. No, it happens all the time! Here is a similar issue:
http://blog.tuningknife.com/2008/09/26/oracle-11g-performance-issue/
+"In the end, nothing I tried could dissuade 11g from emitting the “PARSING IN CURSOR #d+” message for each insert statement. I filed a service request with Oracle Support on this issue and they ultimately referred the issue to development as a bug. Note that Support couldn’t reproduce the slowness I was seeing, but their trace files did reflect the parsing messages I observed."+
I would:
1 - Start by examining historical SQL execution plans (stats$sql_plan or dba_hist_sql_plan). Try to isolate the exact nature of the decreased performance.
Are different indexes being used? Are you geting more full-table scans?
2 - Migrate-in your old 10g CBO statistics
3 - Confirm that all init.ora parms are identical
4 - Drill into each SQL with a different execution plan . . .
Raid 5 Don't believe that crap that all RAID-5 is evil. . . .
http://www.dba-oracle.com/t_raid5_acceptable_oracle.htm
But at the same time, consider using the Oracle standard, RAID-10 . . .
Hope this helps . . .

How to configure SAP 4.7 to Oracle 9i Real Application Cluster ?
We are using SAP 4.7 running on Oracle 9i with HP-UNIX clustering.
If we change our existing SAP 4.7 for Oracle 9i Real Application Cluster, is it very complicated ?
Do we need to re-install SAP and Oracle ?Both 4.7 and Oracle 9 are already out of support.
If you plan to use RAC then I'd first upgrade the application and the database and then implement RAC. You won't have support for your environment without additional costs.

Hardware Architecture of Real Application Cluster (RAC)
I'll implement Oracle 9i with Real Application Cluster (RAC). I now have two Sun SF280R servers.
Can I use ONE common storage to build RAC?
SF280R - Storage - SF280R
OR is it necessary to have TWO storages?
SF280R SF280R
|..........\/..........|
StorageStorage
ThanksThe whole idea behind RAC is that there is shared storage for 2 or more database instances. If one instance goes down, the other(s) seemlessly take over. RAC provides insurance against instance failures. Stand by databases (also known as data guard) provide insurance against database (the actual data files) failure.
HTH.
