Basic questions about NWDI structure

Hello All,

I have read some materials about the Java development process within SAP J2EE engine.

Here I just want to confirm with you some knowledge points and ask some questions about the configuration of NWDI before proceeding Java development.

1. There are four systems within SAP Java landscape, the first one is the developer's own PC, on which there should be installed SAP Workplace (actually is a small J2EE engine and the NW developer studio), am I understanding right?

2. Where should the DTR CBS CMS and SLD be installed? on the Consolidation Server? or the TEST Server? or the Production server? or totally on another standalone server?

3. Within one Track (four system), how many DTR server, CBS Server and SLD server should be installed? Does it only need one for each?(All the four system connect to the same DTR/CBS/SLD server?)

4. Can DTR Server, CBS Server and SLD Server be installed on the same host? or should they be installed on separate hosts?

Thank you very much in advance.

Best regards,

Nick
