Is there any DB performance if i set processes=300.

Logically waht will happen if i set processes to 300.
Firstly... determine where the limit was reached because the application actually requires in excess of 150 process or because something went wrong and connections/processes got never released.

Either way, 150 processes is a very low number.

Please remember that PROCESSES goes hand-to-hand with SESSIONS parameter - research how they relate to each other.

What would logically happen if processes is set to 300?... Oracle will allow as many as 300 processes :-)
