Oracle process/thread differences on Solaris vs Win2k
I notice on Win2k, if I have one instance for each of the two databases on a server, I only have two processes named "oracle.exe" running. However, on Solaris, for the same situation, I could have many processes called "oracle" running. And when I look at the processes, it shows some has only one light weight process for the "oracle" process while the others could have for example 11 light weight processes associated with it.
Why the differences? Is light weight processes important here? Is it like thread in Win2k?
