手工安装ORACLE TEXT
grant CREATE TABLE to student;
grant CREATE SEQUENCE to student;
 ORACLE TEXT安装与卸载
 1.创建CTXSYS用户
以SYS用户执行以下脚本：
SQL> connect SYS/password as SYSDBA
SQL> spool text_install.txt
SQL> @?/ctx/admin/catctx.sql change_on_install SYSAUX TEMP NOLOCK
各参数含义：
change_on_install – 设置ctxsys用户密码
SYSAUX – 调置ctxsys用户默认表空间
TEMP – 设置ctxsys用户默认临时表空间
LOCK|NOLOCK – 设置ctxsys用户锁定与不锁定
2.指定默认安装语言
SYS@jzh>conn ctxsys/oracle
Connected.
以ctxsys用户执行如下脚本：
CTXSYS@jzh>@$ORACLE_HOME/ctx/admin/defaults/drdefus.sql
在11.2.0.3版本中，如果不执行以上脚本，那么在执行脚本dr0defin.sql或创建索引时会遇到如下错误：
ERROR at line 1:
ORA-20000: Oracle Text error:
DRG-10700: preference does not exist: CTXSYS.DEFAULT_LEXER
ORA-06512: at "CTXSYS.DRUE", line 160
ORA-06512: at "CTXSYS.CTX_DDL", line 1140
ORA-06512: at line 2
SQL> CREATE INDEX "EXPERIAN2"."IX_COMP_SEARCH" ON "EBA05M5" ("COMPANY_NAME") INDEXTYPE IS "CTXSYS"."CONTEXT";
设置american为默认语言
SYS@jzh>@?/ctx/admin/defaults/dr0defin.sql "AMERICAN";
old   1: SELECT DECODE('&nls_language',
new   1: SELECT DECODE('AMERICAN',
注意：在一些系统中使用text必须指定相关变量，如下列表：
Platform:             Requires path set:    ENV variable:
--------------------- --------------------- -------------------
Linux x86-64          YES                   LD_LIBRARY_PATH
Solaris SPARC64       YES                   LD_LIBRARY_PATH
IBM AIX               YES                   LIBPATH
HP PA-RISC            YES                   SHLIB_PATH
HP Itanium            YES                   LD_LIBRARY_PATH
- If you have the C Shell (csh or tcsh), enter the following:
   $ setenv LD_LIBRARY_PATH $ORACLE_HOME/ctx/lib:$LD_LIBRARY_PATH
- If you have the Bourne shell (sh), Bash shell (bash), or Korn shell (ksh), enter the following:
   $ export LD_LIBRARY_PATH=$ORACLE_HOME/ctx/lib:$LD_LIBRARY_PATH
Run the following command to check if the LD_LIBRARY_PATH environmental variable is set correctly:
$ echo $LD_LIBRARY_PATH
3. 验证
以sys用户登陆数据库执行如下脚本：
SYS@jzh>select comp_name, status, substr(version,1,10) as version from dba_registry where comp_id = 'CONTEXT';
COMP_NAME                                STATUS               VERSION
---------------------------------------- -------------------- ------------------------------
Oracle Text                              VALID                11.2.0.3.0
SYS@jzh>select * from ctxsys.ctx_version;
VER_DICT                                 VER_CODE
---------------------------------------- ----------------------------------------
11.2.0.3.0                               11.2.0.3.0
SYS@jzh>select substr(ctxsys.dri_version,1,10) VER_CODE from dual;
VER_CODE
----------------------------------------
11.2.0.3.0
SYS@jzh>select count(*) from dba_objects where owner='CTXSYS';
  COUNT(*)
----------
       388
SYS@jzh>select object_type, count(*) from dba_objects where owner='CTXSYS' group by object_type order by 1;
OBJECT_TYPE           COUNT(*)
------------------- ----------
FUNCTION                     2
INDEX                       63
INDEXTYPE                    4
LIBRARY                      1
LOB                          2
OPERATOR                     6
PACKAGE                     74
PACKAGE BODY                63
PROCEDURE                    2
SEQUENCE                     3
TABLE                       50
OBJECT_TYPE           COUNT(*)
------------------- ----------
TYPE                        35
TYPE BODY                    6
VIEW                        77
14 rows selected.
SYS@jzh>select object_name, object_type, status from dba_objects where owner='CTXSYS' and status != 'VALID' order by object_name;
no rows selected
如果有无效对象，可手动重新编译。
4. 卸载Oracle text
? 以sys用户执行如下脚本
SQL> connect SYS/password as SYSDBA
SQL> spool text_deinstall.log
SQL> @?/ctx/admin/catnoctx.sql
SQL> drop procedure sys.validate_context;
SQL> spool off
