Oracle process/thread differences on Solaris vs Win2k

Hi,

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?

Thanks,

In Windows this oracle.exe thread manage internally all oracle processes (pmon,smon,server ...) In unix you have a "thread" for each oracle process.

Ask Billy why windows work as it works :D

aren't "oracle.exe" a process rather than a thread? I thought a process can have more than one thread, not the other way around.

Thanks,

oracle.exe is process, the background processes are threads
