Customer continuously seeing below errors in app servers and correspondingly in DB we are seeing processes reached to maximum (4000).

ORA-00020: maximum number of processes (4000) exceeded
ORA-20 errors will not be written to the alert log for the ORA-20 errors.
App server errors :
java.sql.SQLException: Connection has been administratively destroyed. Reconnect.
<JDBC> <BEA-001129> <Received exception while creating connection for pool "mslvProcDataSource": IO Error: Got minus one from a read call>
These errors are resultants of DB processes reaching to the limit. Issue can be resolved by increasing the number of processes allowed for DB, but customer has following queries:
- Is there a impact if we increases process count ( either to app or to DB) ?
- To what maximum setting we can we go?
- Why we get this error all the time?
