“Fatal OSN connect error 12547”的分析

        今日安装一应用，数据库采用的是Oracle 8i。
        按照说明安装并配置，但是无法连接到数据库。查看sqlnet.log文档，内容如下：

    到Google上搜索吧，信息挺少，只好到MSN上找高人请教了。
    网友wish发来的解决帖，并附其翻译（呵呵，怎知俺鸟语不咋地呢？）

1) Make sure your tnsnames.ora have the same correct entries on both local and remote databases.
then lsnrctl reload

确保你的tnsnames.ora文件在本地和远程数据库都有正确的实体名
然后lsnrctl重新加载

2) create a public database link on the local database:
As sys (or a user that can create dblinks):
CREATE PUBLIC DATABASE LINK <choose name="" a="">
CONNECT TO LINKUSER
IDENTIFIED BY
USING ' ';

在本地数据库创建一个公共的数据库的连接 ：
作为sys(或者可以创建数据库连接的用户)：
CREATE PUBLIC DATABASE LINK <选择一个名字>
CONNECT TO LINKUSER
IDENTIFIED BY <有效的密码>
USING '<指向远程数据库的tnsnames.ora文件的服务名>';


3) On the remote database, create a user for the link to use:
CREATE USER LINKUSER IDENTIFIED BY <the above="" password="" valid="">
DEFAULT TABLESPACE USERS
TEMPORARY TABLESPACE TEMP
PROFILE <an profile="" appropriate="">

在远程数据库里创建一个使用连接的用户
CREATE USER LINKUSER IDENTIFIED BY <上面有效的密码>
DEFAULT TABLESPACE USERS
TEMPORARY TABLESPACE TEMP
PROFILE <一个适当的profile>


ACCOUNT UNLOCK;
4) GRANT CONNECT TO <the above="" name="" link="" chosen="">;
or perhaps
grant create session to linkuser;

解锁帐户
4) GRANT CONNECT TO <上面选择的连接>;
或者
grant create session to 连接用户;

Also make sure the tables and column names called in the trigger are valid ones.

    吼吼，希望有用，只有明天试试看了。。。。。。。。</the> </an></the> </choose>
