php ora01017,建立DBLINK报ORA-01017，ORA-02063

今天在WIN32 10G做个DBLINK到LINUX32 11G上，报密码错误，我就郁闷了，我检查了密码在目的数据库上可以正常连接，DBLINK的3个权限也正常，TNSnames.ORA也正常，我差了网上，好像也有这种错误，什么问题啊。

源库TNSNAME.ORA配置文件

orcl =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.171.128)(PORT = 1521))

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = orcl)

)

)

EXTPROC_CONNECTION_DATA =

(DESCRIPTION =

(ADDRESS_LIST =

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))

)

(CONNECT_DATA =

(SID = PLSExtProc)

(PRESENTATION = RO)

)

)

授权和运行

SQL> grant create database link to aaa;

授权成功。

SQL> grant create public database link to aaa;

授权成功。

SQL> grant drop public database link to aaa;

授权成功。

SQL> create database link to_orcl1

2  connect to aaa identified by aaa using 'orcl';

数据库链接已创建。

SQL> select * from aaa.aaa@to_orcl1;

select * from aaa.aaa@to_orcl1

*

第 1 行出现错误:

ORA-01017: invalid username/password; logon denied

ORA-02063: 紧接着 line (起自 TO_ORCL1)
