In case of Oracle JDBC even statements like INSERT, UPDATE, DELETE opens a cursor !!! Remeber to call close on statements i case of ResultSet use rs.getStatement().close()

Increase PROCESSES parameter in the SPFILE.
If you can not stsart the instance, find the pfile.ora, make the changes and start the instance
SQL>startup pfile=c:\........\init<sid>.ora

At the startup time Oracle starts only limited number of processes - between 9 and 15. So it seems that a process consuming application immediatelly connects to Oracle. This may be an application server or a farm of app. servers.

edvinkv

Pls reduce the parallell query processes to fix this issue. (Reduce it by half)

in the init.ora file.. also pls restart the database.

max_parallel_servers=
min_parallel_servers=0 (or you may reduce this also by half)

sagacious

Increase the number of processes of your oracle server...

Go into the console and manage it. But if you are hit with this problem, you should check your codes as this derives mainly from connections opened and not closed and things just accumulate and stops there.
