Windows and maximum processes/threads
Oracle on Windows works differently from other operation systems: instead of having different processes for different tasks there is only on process with different threads.
When stress testing out application on Linux (with 10g Express Edition) I ran into 'TNS-12516: TNS:listener could not find available handler with matching protocol stack'. Raising the PROCESSES setting from the default 40 to 100 removed this error message.
This made me wonder: is there a similar limit to the number of threads in Windows? Or is the maximum number of concurrent settings on Windows only limited by other factors?
