[急救]qe-def-0285 uda-sql-0031

在使用Framework Maneger进行数据库连接时，出现如下所示问题：
QE-DEF-0285 The logon failed.
QE-DEF-0325 The logon failed for the following reson:
RQP-DEF-0068 Unable to connect to at least on database during a multi-database attach to 1 database(s) in:********
UDA-SQL-0031 Unable to access the "*****" database.
UDA-SQL-0107 A general exception has occured during the operation "attach".

ps:FM所安装客户端为win7系统，连接oracle11g。
该问题可以如何解决呢？已有按照网上的一些步骤尝试解决，但都失败了。
谢谢您的及时解答！
