How to configure dispatcher to send the requests to specific server process

[Former Member]

Hello,

We have a Java Web AS that contains a dispatcher and 3 server processes.

Suppose I would like to configure the dispatcher to send the requests just to 2 specific server processes. How do I do that?

Hello Roy,

It is completely acceptable to simply stop one server process and start it up when needed.

Also check this link for details on http locadbalancing in the engine,.maybe you can try the Heterogenous loadbalancing option, where certain applications do not run on all server nodes

Hello Roy,

What kind of request you would like to send for just 2 specific servers?

I don't know exactly what is your requirement, but, probably you'll have two options:

1) Configure your application servers with the work process that you need. You can, for example, has one application just for background process. To make this configuration you'll need to change your instance profile (TA RZ10).

2) Other possibility is to use the logon balance concept. When you use logon balance even with 4 servers in your landscape, you can specify just 2 servers for general users. It's important to remember that you can have more than one logon group. To configure logon balance use transaction SMLG and SM12.

If you need further information please don't hesitate to ask for.

Hi Roy,

To my knowledge J2EE dispatcher balances the load automatically between server processes that active and not marked to shutdown. I don't know official ways to make the dispatcher weighed one server over another (or any other solution similar to Response Time settings in SMLG (for ABAP stack)). May be it can be accomplished by setting Thread Pool settings different for each server process.

Hi guys,

Sorry, I forgot to mention that we are using Java only stack, no ABAP.

Now, if I can't do it from the dispatcher can I disable one server process without deleting it and enable it afterwards when I want to?
