问题描述：
使用sqlplus客户端登录数据库，报错SP2-0642，而使用其它方式plsql或者tnsnames等方式连接数据库均没有问题

[oracle@test2 ~]$ sqlplus adt/[email protected]:1521/srv_test1

SQL*Plus: Release 10.2.0.1.0 - Production on Wed Oct 9 16:04:39 2013

原因：
The cause of this problem has been identified and verified in an unpublished Bug 6135152. ORA-25406 With Server Side TAF, And //HOST:PORT/SERVICE_NAME Connect String.
使用TAF连接并用EZCONNECT连接数据库时，触发了数据库相关bug

解决方法

方法1

1，去掉默认的端口号1521，可以解决

C:\Users\wj>sqlplus adt/[email protected]/srv_test1

SQL*Plus: Release 10.2.0.1.0 - Production on 星期三 10月 9 16:09:00 2013

连接到:
Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 - 64bit Production
With the Partitioning, Real Application Clusters, Automatic Storage Management,
OLAP,
Data Mining and Real Application Testing options

SQL>


方法2，修改service的配置为默认选项
原有service创建方式
srvctl add service -d ms4adb -s srv_4a2 -r ms4adb -a ms4adb -P basic -e select -m basic -z 180 -w 5

现有service方式，使用默认参数配置，即可正常连接
srvctl add service -d ms4adb -s srv_4a2 -r ms4adb -a ms4ad


方法3，客户端sqlplus升级oracle 11.2，也可解决相关问题
Bug is fixed from release 11.2 onwards.
Check for one off patches for your release / platform via Patch 6135152
