首先进入$ORACLE_HOME/rdbms/admin目录,在sqlplus下运行@awrrpt脚本,按照提示一步一步就可以达成,导出的格式有两种,txt格式和html格式。
在OTN上,有一个DBA新feature系列,第六周就是专门讲的这个feature,大家可以去那里了解一下(中文的)

我用FineReport报表、JasperReport等报表开发工具连oracle时都出现过类似问题,主要原因是由于监听器不识别java应用程序中定义的数据库名称导致的,需要修改设计器中数据连接所定义的数据库名。ORACLE是通过外界提供的服务名来判断是否建立连接的,所以要保证设计器端跟数据库端的数据库名称匹配。ORACLE数据库的安装目录中通常包含这2个文件:tnsname.ora跟listener.ora。Tnsname.ora是客户端的配置文件,listener.org是监听程序的配置文件。在tnsname.org里面可以找到对应的数据库名。
最近一直在弄db2数据库,以至于oracle放松了很多,今天测试部门过来问了个关于oracle的问题,解决的不是很完美.问题是这样.测试从客户的生产库expdb回来的数据,要在实验机器上导入,结果报错,让我过去看看。
我过去看了看,报了6550错误。于是上google搜索了下6550错误的成因,有很多帖子说是导入的用户没有足够权限,于是我grant sysdba to user,可是这样后,仍然报6550错误,很是诧异。仔细看了看测试给的错误截图,有2条命令 一个是 impdp user/password file="/dev" 报file不存在,还有一个命令是imp user/password file="/dev" 报的是6550错误。再上google查了一下,还有说6550错误需要用impdp导入。于是觉得应该用第一条命令。仔细看了看语法,把 impdp user/password file= 改成了impdp user/password dumpfile= .到了测试部门一看,果然用这个命令可以,可是。同时出现了新的问题。说数据泵和数据库版本不一致,这个问题我还不知道怎么解决。只好让测试重新装了一次oracle,才解决的。
