Set of süden today morning when connecting sql developer, I get the following error

To perform the requested operation, an error has occurred:

0 vendor ID

Help, please

Problem was the automatic change of type tns connection. Somehow, she had moved from network alias to connect identified and because of that, I was getting error. I changed to alias network and gave the names of tns and it worked.
