installation/deinstallation of Oracle Text in Oracle 12c

Best Title

In Oracle 12c Database you can’t manually install or de-install Oracle Text component (anymore), if your database was upgraded from 11g to 12c with Oracle Text component already installed then you are OK.

To install in 12c , you will be using DBCA (Database Configuration Assistance):

*** Command Line silent approach (syntax):

dbca -silent -configureDatabase -sourceDB <db unique name for RAC or SID for Single Instance db> -sysDBAUserName <user name with SYSDBA privileges> -sysDBAPassword <password for sysDBAUserName user name>] -addDBOption ORACLE_TEXT

ora47> dbca -silent -configureDatabase  -SourceDB ora47 -sysDBAUsername sys -addDBOption ORACLE_TEXT

Look at the log file “/ora47/ora47/cfgtoollogs/dbca/ora47/ora47.log” for further details.

*** GUI interface:

cd /etc

vi oratab

//add your database SID:ORACLE_HOME

ora47:/oraclex/ ora47/product/12.1.0:N

export DISPLAY=PC_SICO:0.0












If you face the above the problem, then you need grant  execute the following system packages to “PUBLIC” :


SQL> grant execute on sys.dbms_sql to public;


SQL> grant execute on sys.dbms_job to public;


SQL> grant execute on sys.dbms_lob to public;

and that is it….you have successfully installed Oracle Text.

select * from dba_registry where COMP_ID=’CONTEXT’ ;


if you want to de-install the Oracle TEXT component you can use DBCA again and “uncheck” the component.


if whaever reason you couldn’t do that then use the traditional 11g way:

SQL>drop procedure sys.validate_context;


select comp_id, comp_name, version, status from dba_registry where COMP_ID=’CONTEXT’;
SELECT object_name FROM dba_objects WHERE status = ‘INVALID’;
