Does it include the Grid Infrastructure (GI) software? Well, SE includes RAC, so that requires GI, so not sure why you would think it was an EE feature.
Does it include Grid (Cloud) Control Software? Well, that is a separate product. Cloud control must be installed on an EE database, but that EE database does not have to be licensed separately, provided it is only used for a Cloud Control installations, and an RMAN catalog if you want it.
I mean, my client got license for 126.96.36.199 version and they chosen filesystem as default storage for storing their DB files. (Enterprise Edition) here they didn't install any Gird infrastructure (GI) software so only I am asking do we need separate license for GI on 188.8.131.52 version.
