Scripts - Processes, CPU, Max. Connections

Hi all,

Can any one please tell me how to find these in Unix (Commands)

  1. Too many processes connected to the server.

  2. High Utilization of CPU.

  3. Maximum Number of connections with the database.

OS: Sun Solaris 5.8
DB : Oracle 10g

Thanks and Regards,
Prashanth
