Oracle中如何编译失效的对象

在日常数据库维护过程中，我们需要及时检查数据库中存在的失效对象信息，对于存在异常的对象需要重新编译，各种对象类型可参见如下编译方法：

检查生成无效对象的名称，并存放object.lst文件中

pool objects.lst
set pagesize500
set linesize 100

select substr(comp_name,1,40) comp_name, status, substr(version,1,10) version
from dba_registry
order by comp_name;

select substr(object_name,1,40) object_name,substr(owner,1,15) owner,object_type
from dba_objects
where status='INVALID' order by owner,object_type;

select owner,object_type,count(*)
from dba_objects
where status='INVALID'
group by owner,object_type order by owner,object_type ;

spool off

生成后关闭sqlplus的spool记录

各个对象的编译方法分别如下：

alter package . compile;
alter package . compile body;
alter view . compile;
alter trigger compile;
