1.建立CTXSYS使用者
以SYS使用者執行以下指令碼：
SQL> connect SYS/password as SYSDBA
SQL> spool text_install.txt
SQL> @?/ctx/admin/catctx.sql change_on_install SYSAUX TEMP NOLOCK
各引數含義：
change_on_install – 設定ctxsys使用者密碼
SYSAUX – 調置ctxsys使用者預設表空間
TEMP – 設定ctxsys使用者預設臨時表空間
LOCK|NOLOCK – 設定ctxsys使用者鎖定與不鎖定
2.指定預設安裝語言
SYS@jzh>conn ctxsys/oracle
Connected.
以ctxsys使用者執行如下指令碼：
CTXSYS@jzh>@$ORACLE_HOME/ctx/admin/defaults/drdefus.sql
Creating lexer preference...
PL/SQL procedure successfully completed.
Creating wordlist preference...
PL/SQL procedure successfully completed.
Creating stoplist...
PL/SQL procedure successfully completed.
PL/SQL procedure successfully completed.
Creating default policy...
PL/SQL procedure successfully completed.
在11.2.0.3版本中，如果不執行以上指令碼，那麼在執行指令碼dr0defin.sql或建立索引時會遇到如下錯誤：
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

設定american為預設語言
SYS@jzh>@?/ctx/admin/defaults/dr0defin.sql "AMERICAN";
old 1: SELECT DECODE('&nls_language',
new 1: SELECT DECODE('AMERICAN',
LA

注意：在一些系統中使用text必須指定相關變數，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. 驗證
以sys使用者登陸資料庫執行如下指令碼：
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
如果有無效物件，可手動重新編譯。
4. 解除安裝Oracle text
? 以sys使用者執行如下指令碼
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

ORACLE TEXT安裝與解除安裝
