TNSNames configured properly

After multiple lookups, the reason is:

specific reason: The 64-bit Win7 will install the 32-bit application into the program Files directory by default, and the two parentheses may be frustrating for Oracle. Change the installation path for a more "popular" path, the installation directory of "()" removed, changed to "program Files x86" Reinstall Plsql, database connection again, all problems are resolved, found can log in, OK.

Everything is caused by a 64-bit system!

the default installation path

Workaround:

After uninstalling the software, reinstall to the non-default path (for example: D:\Program), problem solving, can be used normally!
