If the clusters are identical (means they have similar properties, provide similar services...), then they are homogeneous. Else they are heterogeneous.


Who says nothing is impossible? I've been doing nothing for years

Hi Rahul,
i didn't get any meterial for this.i think what sugana explained is correct bcz i read the article as follows.
By default, every server in a BEA WebLogic Server Cluster is homogeneous´┐Żhosting all of the same application services. Automatic routing, however, frees your system administrator to partition and dynamically repartition the business processing within the cluster as desired´┐Żfor example, specializing some servers to handle checking accounts and others to handle savings.

seenu

Hi Seenu,
Now I get it.
What the author means is that by deploying the and application and its components to a cluster rather than to individual servers makes it homogenous.
On the other hand if lets say I deploy application 1 to server A and Application 2 to Server B where in servers A and B form a Cluster then this is a hetrogenous deployment.
 
I agree. Here's the link: http://aspose.com/file-tools
