How to increase number of connections in Oracle

[bittus]

So how will I change the max. no. of connections ?

How can I check the current max. no. of connections ?

There is nothing called connection parameter.

You increased the process. Now increase the session and transaction using the similar command which you used previously.

To check number of sessions.

select * from v$parameter where lower(name) = 'sessions'
