I´m installing SAP ECC with DB2 in a Windows MSCS environment. I already installed all the critical components in the cluster, and now I need to install the CI. I´m using only 2 nodes. I have the following doubt:
Do I need to install a local CI in the first node and the local DI in the second node and that is enought in case of failure?
Do I need to install a local CI in the first node and then a local CI in the second node too?
In this context CI and DI is the same?
Because in the installation guide the paragraph is a little bit confuse:
To protect system components that are non-SPOFs, for example application servers, you have to install them as multiple components. In this case you must install at least two application servers (one central instance and at least one dialog instance) on two different hosts.
Thanks a lot.
