When to add a new server node in Java system and adding server node will impact the system in what ways.

How to create and add a server node with existing server nodes.

Thanks

Stop system (specific instance where you want to add additional node), open config tool --> Server --> add server.

for memory parameter, i suggest you can copy all the parameters from existing server node including Java memory this will make sure that you have same parameters across all the serer nodes.

First time the new server node will take some time to start becuase it has to copy all the relevant files to own filesystem. Make sure you have sufficient freespace on the instance directory.

If you are using SAP Enterprise portal -> KM(Knowledge Management), please do have a look at note 798633 after adding additonal server node(s).

Thanks

Load balancing.

Multiple server nodes help you to optimize your resources better.

For e.g. when one servernode is in Full Garbage Collection the other still can use the CPU to process.

How to create and add a server node with existing server nodes.

Open Configtool

Server --> Add Server

Make the necessary parameter settings as per teh other server node. (Make sure you have ample RAM)

Hi,

Also, before you add server nodes in Java system, make sure that you have enough resources in the system. Check SAP note 723909 for this. Check below thing:

For each JavaVM on the server, all Java memory must fit completely

into physical memory (no paging)!

Therefore the rule of thumb for number of server nodes for SUN and HP

JavaVM with 1 GB Heap each will be

#ServerNodes = (AvailableMemory / 1.5 GB)

and factor 2.5 should be used instead of 1.5 for 64 bit with 2GB heap size.

Thanks
