In Linux systems, you can use the following command to check if Oracle is running:

  1. Check if the database instance process is running by using the command ps -ef | grep pmon. If you see a process like ora_pmon_ORCL, then the Oracle instance has been started.
  2. Check the status of the listener by using the command lsnrctl status. If the listener is running, it means Oracle has been started.
  3. Connect to the Oracle instance using the command sqlplus / as sysdba, and execute the following command to check the status of the instance.
  4. You can choose the status from v$instance.
  5. If the status is “OPEN”, it means the Oracle instance has been started.

These commands can be executed in the terminal of a Linux system.
