数据库日志发现经常报以下错误：Unable to restore resource manager plan to '':
ORA-02097: parameter cannot be modified because specified value is invalid
ORA-00439: feature not enabled: Database resource manager

客户的数据库版本是oracle 10.2.0.1,标准版。
通过查metalink,在oracle 10.2.0.1标准版中会出现这个问题，而且是bug,错误可以忽略。
如何判断数据库是标准版还是企业版呢？有以下两个方法:

1.sqlplus "/as sysdba" 版本查询
select * from v$version
Oracle Database 10g Enterprise Edition Release 10.2.0.1.0
而标准版没Enterprise Edition 字眼出现
Oracle Database 10g Release 10.2.0.1.0

2.查询v$option视图
标准版里面很多功能都是false 比如partition false
而企业版本里面则为true 比如partition true

以下附件为metalink解释：
