在Oracle9i Rlease2中，Oracle的全文检索技术被称为:Oracle Text，功能十分强大。Oracle Text是Oracle9i采用的新名称，在Oracle8/8i中它被称作Oracle interMedia Text，在Oracle8以前它的名称是Oracle ConText Cartridge。
Oracle Text组件可以在安装数据库的时候选择，缺省是安装的，如果没有安装，那么可以按照以下方式手动安装Oracle Text。
1.创建存储表空间
$ sqlplus "/ as sysdba"

请注意如果漏掉drdefus.sql脚本，使用过程中将会出现以下类似错误：ERROR atline 1:
ORA-29855: error occurred in the execution of ODCIINDEXCREATEroutine
ORA-20000: interMedia Text error:
DRG-10700: preference does notexist: CTXSYS.DEFAULT_LEXER
ORA-06512: at "CTXSYS.DRUE", line 126
ORA-06512:at "CTXSYS.TEXTINDEXMETHODS", line 54
ORA-06512: at line 1
这样就完成了手工安装全文检索工具。
