Alternate of ps command in windows:

Using “tasklist” command Oracle DBA can able to trace all running processes in windows including oracle,sqlplus,exp,imp and others. Tasklist command is very closer to ps command. Using tasklist command Oracle DBA can able to access process ids, session ids, cpu time, and modules of running processes in Oracle on Windows.

    TASKLIST /FI "USERNAME ne NT AUTHORITY\SYSTEM" /FI "STATUS eq running"

Consider a case in which we have 20 databases on the server and we need to find out how many oracle services are currently running:

Well you may type the below command to know this:

c:\>tasklist -svc
