PlSql安装报错 plsql some oracle net versions cannot connect from a path

错误信息：

Warning: Some Oracle Net versions cannot connect from a path with parentheses!
This is due to Oracle Bug 3807408. Please ensure that your Oracle Net version
does not suffer from this bug, or install in a different directory.

原来提示了，不能有括号，呵呵
修改了安装路径就没有问题了

本以为这个问题忽略过去没什么影响，结果报ora-12514,错误！各种测试，配置完全正确，无奈重装更改路径后，顺利解决！

tnsping 服务名 能通；

sqlplus sys/oracle@192.168.56.102:1521/test也能正常登陆

就是PL/SQL登陆报错。ORA-12514: TNS: 监听进程不能解析
