How to check Oracle processes in windows

Hi Oracle DBA friends,

Today’s Tip for Oracle on windows.

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

But there is no command in windows just like ps in unix. Means there is no way to find out running processes in windows system. There is only task manager available in windows system. Using task manager we can check running processes in windows system. It is very difficult to monitoring and administrating Oracle on windows systems for Oracle DBA.

Alternate of ps command:

No it is not TRUE. Windows has own command to trace all running processes in the system. Using “tasklist” command we can trace all running processes in windows including oracle,sqlplus,exp,imp and others. Tasklist command is very closer to ps command.

Please check help of tasklist command.

C:\>tasklist /?

TASKLIST [/S system [/U username [/P [password]]]] [/M [module] | /SVC | /V] [/FI filter] [/FO format] [/NH]

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

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

All the best,
