I installed an emule Verycd client last night, I was not bad. I found problems this morning. Oracle launched the ORA-12560 error. The estimated listener's port has conflict, and uninstall the emule Verycd and restart, everything normal now.
Think about it, emule Verycd is set, I set the port in more than 4,000, theory and my two Oracle ports have no conflict, it is really unbearable.
