how may even I can't even open the database, and how is it possible to use what way to open, the most main is connected to the database instance is not an error is all no problem, now the most trouble thing is that 12514 exactly is what is going wrong, the website that some try a lot of, not a used, connection status without any change, 12514 the wrong thing for two or three months, is nothing, after all

CodePudding user response:

Even I can't even? Whether the Oracle on the Windows, up SQLplus even up to 12514, an error if it is, open the Oracle service in service
