本文为大家讲解的是创建dblink ORACLE数据库报错:ora-02063/ora-01017 解决方法，感兴趣的同学参考下。
问题描述：
一回家，某运营商电话至，创建dblink报错ora-02063/ora-01017
关于这个BUG，遇到不是一次了，ORACLE对于该BUG 描述如下
Bug 6738104: ORA-01017 ORA-02063 WHILE CONNECTING FROM10G TO 11G VIA PUBLIC DBLINK
错误原因：
The following Bug 6738104 was logged for this issue which was closed as not abug saying the cause being introduction of password case sensitivity feature in11g
When one creates a database link connection, a user name and password for theconnection needs to be defined. When the database link is created, the passwordis case sensitive. Before a user can connect from a pre-release 11g database toa 11g release database and as the password case sensitivity is enabled bydefault, you must re-create the password for this database link using alluppercase letters.
The reason you need to re-create the password using all uppercase letters is sothat it will match how Oracle Database stores database link passwords. OracleDatabase always stores this type of password in uppercase letters, even if thepassword had originally been created using lower or mixed case letters. If casesensitivity is disabled, the user can enter the password using the case thepassword was created in.
当低版本通过dblink连接11G库时，默认会将密码改为大写。
解决方法：
重新创建dblink,密码使用双引号+小写即可
例：
create database link db_test
connect to wxboss
identified by "wxboss"
using '(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL =TCP)(HOST = 192.168.99.100)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SID = wxboss)
)
)';
