Cloning

[ramdas]

can anybody suggest how To Clone An appserver on m/c "A" to m/c "B".This is to avoid single point failover.(Both M/C "A" and "B" has WAS installed on it).
Thanx in advance.

The Java Ranch has thousands of visitors every week, many with surprisingly similar names. To avoid confusion we have a naming convention, described at http://www.javaranch.com/name.jsp . We require names to have at least two words, separated by a space, and strongly recommend that you use your full real name. Please log in with a new name which meets the requirements.
Thanks.

You can do either horizontal or vertical clustering. I you think you have a powerful machine which is underused, use vertical clustering. The disadvantage of doing this is all application servers run on the same machine and if something goes wrong with this machine there is no failover. I you have serveral less powerful machines, use vertical clustering.
If you are using 3.5, right click the application server to clone it. Use Model to control all clones.

Hi Jun Hong
i know the concept of verticle and horizontal cloning on WAS 3.5
i have acheived the horizontal cloning.
i would like to know how to implement vertical cloning.like any setting/configuration changes needed.
thank you

The only requirement to clone across machines is that the installed code files (your JARs or .class files) must be located in exactly the same place on both machines (identical directory structures). After you've done tihs, it's no different than cloning on a single machine -- it's all handled by the admin tool.

ramdas,
I will be forced to block your account unless you confirm to the Naming Conventions on Javaranch as stated above.
This is the only rule we ask of you so please comply by it.
Thanks.
