Today I noticed all these processes under Linux 64 bit.
Oracle Enterprise 11g 64 bit.

What these ora_***_sopen processes are ?
I don't remember seeing them in the past.

Eh? Never noticed before? Someone created a database with a SID of sopen. these are all normal database processes.

sopen is the database running on the server. So they are normal ?

How come I did not noticed them before ?

I do now know why, but I can assure you they were all there if the database was up and running. Look them up if you would like to know what they are at http://en.wikipedia.org/wiki/Oracle_Database#Oracle_processes
