has anyone come across an issue where the user SYSTEM has many inactive process for OMS program, in fact all avaliable processes are taken up over a small time-frame giving a TNS-12516 error when you try to make a connection (for example via Toad) after all processes have been taken. In stopping the DBconsole service all these processes are killed and processes made available again. Also, when you open OEM you get the message "Enterprise Manager is not able to connect to the database instance. The state of the components are listed below." but the Instance, Listener and Agent Connection to Instance are showing up and running (you can see the up and green arrow!). Not sure why this is occuring and have researched but can not find a solution!!
