如何通过imp/exp重建oracle数据库的对列表

试用版版本8.1.7.0.0-9.2.0.8.0，这个文档中的信息适用于任何平台。

文档目的是提供一个脚本来降低高水位线，任何用户可以对高级队列（AQ）进行导入导出。

DBA在使用次脚本中，需要在书库中有关AQ的对象，以减少空间消耗，提高入队/出队的现象，并减少资源消耗队列的监控进程。

执行脚本的环境sqlplus或者isqlplus

配置脚本。在这个文件中包含两个脚本，generator.sql和run.sql第一个脚本是构建
前期的一些准备，而后运行run.sql执行生成的脚本。当然您可以修改这些脚本以保证这是
适合您的。

请打开一个新的sqlplus会话上正确运行generator.sql脚本，以正确生成脚本。

注:由于脚本生的都是截断操作，就其性质之言其破坏性是很大的，应在运行前先检查脚本，在一个适当的测试环境使用。

运行脚本

权限：需要sys或sysdba身份

用法：SQLPLUS“SYS <PASSWORD> / AS SYSDBA”@ generator.sql
SQLPLUS“SYS <PASSWORD> / AS SYSDBA”@ run.sql

注意：这个脚本只提供学习，而不是oracle支持的服务。它虽然已被内部测试，但是
我们保证一定合适您的测试环境，请使用之间校对脚本。
