In unix there is command called “ps“. Using ps command Oracle DBA can check all type of processes which are running in system. Ps command is very useful to administrating and monitoring oracle in unix/linux systems for all Oracle DBA.

But unfortunately there is no command available in windows just like ps in unix! Means there is no way to find out running processes in windows system using command line! Only task manager option is available in windows system for Oracle DBA. Using task manager we can check running processes in windows system. Task manager is GUI tool. Sometimes it is very difficult to monitoring and administrating Oracle on windows systems for Oracle DBA using GUI tool.

Alternate of ps command in windows (Great tip for Oracle DBA):

No it is not TRUE. Really !!! Windows has own command to trace all running processes in the system. 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.

Please check help of tasklist command.

TASKLIST /S system /U domain\username /FO CSV /NH

TASKLIST /S system /U username /P password /FO TABLE /NH TASKLIST /FI “USERNAME ne NT AUTHORITY\SYSTEM” /FI “STATUS eq running”

Example:

C:\>tasklist

Image Name                   PID Session Name     Session#    Mem Usage

========================= ====== ================ ======== ============

System Idle Process            0 Console                 0         16 K

oracle.exe                         4 Console                 0     282,100 K

smss.exe                     636 Console                 0        420 K

csrss.exe                    692 Console                 0      6,496 K

winlogon.exe                 716 Console                 0      1,336 K

services.exe                 760 Console                 0      4,020 K

lsass.exe                    772 Console                 0      7,188 K

svchost.exe                  956 Console                 0      5,568 K

Means using tasklist or tasklist -v command we can monitor and manage our oracle processes.

Now never tell that you don’t have ps command for windows !!!
