How can I increase the number of processes in my busy Red Hat Network Satellite (version 5 or above) when it is showing "ORA-00020: maximum number of processes exceeded"?

Issue

• Getting exceptions from Red Hat Network (RHN) Satellite server.

SQLConnectError:(20, 'ORA-00020: maximum number of processes (%s) exceeded\n',rhnsat', 'Connection_Connect(): begin session') </code>

• RHN is flooding us with traceback messages as multiple clients attempt to check in.
• The messages seemingly contain the same error message (DatabaseError: ORA-00018: maximum number of sessions exceeded).
• Complete Traceback is as below :

Traceback (most recent call last): 
  File "/usr/share/rhn/server/apacheHandler.py", line 65, in headerParserHandler
