NWDI role in different technical insallations

Hello,

I want to configure development, consolidation, test, and production system on different machines. I just want to clear the understanding whether NWDI will be installed on every machine or It should be only on development system with CE and all CE systems would use it as centrally. Can I then release software process from one system to other system Dev >consolidation >test-->production.

how will be the release process?? only in one direction Dev----


>production??? if I find any error in test system which I want to remove in by developers in development system, does in this case test sytem can send the software components to development system for making error free?? or just development system will remove the errors and release it again with a new track???

additionaly I want to understand whole process of software release with developement to production systems. Can any one recommend me any source for reading??

Regards,

Naeem

    HI,

    no u dont need to install NWDI on all the servers

    u can have one central system with NWDI installed, create a track in the system where u have installed NWDI and in the runtime systems configuration u have to give the details of other systems dev, cons which u want to have in the landscape.

    Dev and cons are the only two systems with source code repository. that means u can do corrections only in these systems,

    Test and production systemns only provide u a runtime environment.

    Regards,

    Satya.

    You need only one (high available if you have a lot of development going on) NWDI installation, preferably on its own hardware. It is highly discouraged to run NWDI together with another SAP system on the same hardware, because of the resource NWDI requires and the possibility of system restarts during deployment from NWDI to the run-time system.

    Developments and fixes always go from Development to Production (which is the normal development process). You do not need a new track for fixes to Production systems. You can use the Consolidation stage to make fixes to productive code when you're already developing a major update in the development stage of your track. The changes made in the consolidation stage will automatically flow back to your development stage. This may raise integration conflicts though in case you updated sources that have already been updated in the development stage. NWDS contains an Integration Conflicts view to handle these.

    Kind regards,

    Pascal
