今天在升级一套10204 db时，发现OLAP组件有异常，由于该组件对该系统来讲无用，故可以remove，查询dba_registry信息如下：

SQL> Col comp_name FOR a35

SQL> Col STATUS FOR a15

SQL> SET LINES 150

SQL> SELECT comp_name,version,STATUS FROM dba_registry;

metalink 上的一篇文档中提供了如何remove OLAP组件的方法，对于10g~11g版本，

执行如下几个sql scripts即可：

SQL> @ /olap/admin/catnoamd.SQL

SQL> @ /olap/admin/olapidrp.plb

SQL> @ /olap/admin/catnoaps.SQL

SQL> @ /olap/admin/catnoxoq.SQL

SQL> @ /olap/admin/cwm2drop.SQL

++++++ 执行完成以后，再次查询dba_registry，将会发现OLAP组件的状态为remove，如下：++++++

如果是10g以前版本，可以使用如下方法：

1) drop the olapsys schema;

2) remove the olap option from a Oracle9i Database:

% sqlplus / nolog

SQL> conn / as sysdba

SQL> @ /cwmlite/admin/onedrop.sql

SQL> @ /olap/admin/olapidrp.sql

3) create the database using the Database Creation Assistant (dbca)

and then remove the olap script from the list of scripts to be executed.
