The oracle database allocates memory equivalent to the SGA parameter.
Thsi is needed to only start the database and to keep it running.
But as new user connect to the database and perform theis tasks. Each user has its own process on the server. This process consumes memory.

So, such connections per database differs.
In my case i have three database opn the server.
Out of the three, one database consumes apporx 80% of the CPU and memory. This is just an estimate depending on the number of connections see at the database level.
Thats why i need to find the memory usage per database.
