Amazing Tools , If you install Oracle Database After that you remember that you should enable/Disable some Feature Like Oracle Security ad you Forget Script That Located in RDBMS/admin the What Reinstall Again

In ORACLE 11gR2 you Can do this Easily Just Follow The Below Steps :

The chopt tool is a command-line utility that is located in the ORACLE_HOME\bin directory. The syntax for chopt is as follows:

chopt [ enable | disable] db_option

The possible values for db_option described in the following table.

dv	Oracle Database Vault
lbac	Oracle Label Security
olap	Oracle OLAP

rat	Oracle Real Application Testing
ode_net_2	Oracle Database Extensions for .NET 2.0

 Example :

To enable the Oracle Label Security option in your Oracle binary files

srvctl stop database -d ORCL

cd %ORACLE_HOME%/bin
chopt enable lbac
