Grid Types in Oracle 11g

Oracle Tips by Burleson Consulting

Oracle 11g Grid & Real Application Clusters by Rampant TechPress is written by four of the top Oracle database experts (Steve Karam, Bryan Jones, Mike Ault and Madhu Tumma).  The following is an excerpt from the book.

Grid Types

This is not a complete list, but a starting point to learn about grid types.  The grid types listed below are not mutually exclusive.  Many grid implementations have attributes belonging to multiple grid types.

  • Clusters  

  • Data Grid  

  • Compute Grid  

  • Enterprise Grid  

  • Department Grid  

  • Open Grid  

  • Partner Grid  

  • Scavenging Grid  


Dr. Robert Cohen, in his paper “Cluster and Grid Computing in Japan: Today and in 2010” explains, “Clusters are a first step in the use of grids.”  Clusters are multiple servers, usually combined via some type of network protocol to provide high availability or load balancing.

Data Grid

A data grid is the storage piece of a grid.  A data grid is responsible for housing and providing access to data.  Users do not need to be concerned with the location of the data or how wide the data is distributed.  The data set sizes used in grid computing are sometimes revolutionarily large.  Data grid performance depends on the network connection speed, because a grid is highly network-dependent. 

Compute Grid

A compute grid is created for computational intensive batch applications.  Batch jobs times vary and can be measured in microseconds or years.  Sun Microsystems claims that the Sun Grid is “the world’s first and only true compute utility.”

Enterprise Grid

According to the OGF, “An enterprise grid is a collection of interconnected (networked) grid components under the control of a grid management entity (GME). An enterprise grid is typically managed by a single enterprise - i.e. a business entity is responsible for managing the assignment of resources to services in order to meet its business goals. The resources and services may or may not be owned by the business; for example, in the case of managed services or a service provider/outsourcer.  An enterprise grid may be confined to a single data center or it may extend across several.”

Department Grid

A department grid is an enterprise grid on a smaller scale.

Open Grid

According to Grid Wise Tech, “Open grids provide controlled access to resources, services and applications for the public.”

Partner Grid

According to Grid Wise Tech, “Partner grids enable collaboration and resource sharing between business partners within a dynamic security framework.”

Scavenging Grid

A scavenging grid is most commonly used with large numbers of desktop machines. Machines are scavenged for available CPU cycles and other resources. Owners of the desktop machines are usually given control over when their resources are available to participate in the grid.
