Applies to:

Oracle Net Services - Version 9.2.0.1.0 and later
Microsoft Windows (32-bit)

Symptoms

TNS-12500: TNS:listener failed to start a dedicated server process

TNS-12560: TNS:protocol adapter error
TNS-00510: Internal limit restriction exceeded

These errors should normally occur on the server when resources have been depleted, not due to an Oracle problem, but perhaps due to the physical usage of Oracle (meaning Oracle consumes OS resources as any other program would)
