Re: diff btw oracle9i Enterprise and 9i RAC

Oracle 9i Enterprise is the core database server product offered by oracle.

RAC

http://www.oracle.com/customers/products/rac.html

Real application Cluster. Lets you hook up multiple CPU's/computers to support an application. Usually used to get a number of inexpensive Intel boxes to have higher reliability and computer power than one Intel CPU by itself.

Re: diff btw oracle9i Enterprise and 9i RAC

Enterprise basically means one server
RAC = Real Application Clusters, meaning more than one server (cluster)

I'm sure that the Oracle site may provide more information particularly for later versions i.e. 10G (GRID)

Oracle9i Enterprise Edition is an object relational database that is scalable and easily manageable.

Real Application Clusters: Improves the scalability and availability of a database by allowing multiple copies of the Oracle software to access a single database.

Re: diff btw oracle9i Enterprise and 9i RAC

Hi Chan,

As Steven and Michael mentioned,

Oracle 9i Enterprise Edition is the core Database Server which includes the RDBMS, PL/SQL, Precompiler, Networking, interMedia Text, JDBC, JavaVM, Enterprise Java Beans, Corba and Java Server....etc products.

Oracle 9i (RAC) Real Application Clusters is contained within the Oracle9i Enterprise Edition. If you install 9i EE onto a cluster, and the Oracle Universal Installer (OUI) recognizes the cluster, you will be provided the option of installing RAC. Most UNIX platforms require an OSD installation for the necessary clusterware. For Intel platforms (Linux and Windows), Oracle provides the OSD software within the Oracle9i Enterprise Edition release.

The cluster and the cluster software, must be installed and configured. The RAC option must be added using the Oracle Universal Installer, which necessitates the existing DB instance must be shut down.

Certifications for Real Application Clusters are performed against the Operating System and Clusterware versions. The corresponding system hardware is offered by System vendors and specialized Technology vendors. Some system vendors offer pre-installed, pre-configured RAC clusters. These are included below under the corresponding OS platform selection within the certification matrix.

RAC configuration is to enable Concurrent Processes to work on multiple nodes. Cluster environment is defined as a system built with a multitude of nodes sharing local resources (Disks, CPU power, Printer queues...) and offering cluster-wide services (Security, Syncronization,Communication). RAC provides scaleability and protection from significant failures, such as node failures and to perhaps a lesser extent network failures.

RAC is supported on HP-UX Extended Cluster for distances up to100km with MC Serviceguard 11.14 or later, with HPUX SLVM or VxVM/CVM 3.5 as volume manager.
For supported DWDM equipments,users should check with HP.

Re: diff btw oracle9i Enterprise and 9i RAC

Hi

Oracle9i Enterprise edition is relational database that is runiing on single server (database server)

RAC: Improves the availability of a database by allowing multiple copies of the Oracle software to access a single database

In Enterprise version if the database server breaks down, database will not be available. whereas in RAC if one cluster breakdown we can access the database through another cluster

Re: diff btw oracle9i Enterprise and 9i RAC

hi,

i would also add:

o RAC is an option of the database.
o Oracle SE comes with RAC standard.
o Oracle EE has RAC as an OPTION.
