When you install Oracle Database, by default Oracle Label Security is not enabled.

You must register Oracle Label Security with the database. Afterwards, you must enable the default Oracle Label Security user account, LBACSYS. After you register Oracle Label Security, you can disable and re-enable it when necessary.

If you are using a multitenant environment, then only register Oracle Label Security in the pluggable databases (PDBs) in which you plan to create Oracle Label Security policies. Because Oracle Label Security is not designed to protect data dictionary objects, you cannot create policies in the root.

You can query the DBA_OLS_STATUS and CDB_OLS_STATUS data dictionary views to find if Oracle Label Security has already been registered and enabled.

1. Log into the database instance as user SYS with the SYSDBA administrative privilege.

   sqlplus sys as sysdba
   Enter password: password
   

2. If you are using a multitenant environment, then connect to the appropriate PDB.

   For example, to connect to the PDB hrpdb:

   CONNECT SYS@hrpdb AS SYSDBA
   Enter password: password
   

   To find the available PDBs, query the DBA_PDBS data dictionary view. To check the current PDB, run the show con_name command.

3. Run the appropriate query to find if Oracle Label Security has been registered and enabled.
   • If you want to find the Oracle Label Security status for a non-multitenant database, or in a multitenant environment for the root only or an individual PDB, then query DBA_OLS_STATUS. For example:

     SELECT * FROM DBA_OLS_STATUS;
     
     NAME                 STATUS  DESCRIPTION        
     -------------------- ------- -------------------------------------
     OLS_CONFIGURE_STATUS TRUE    Determines if OLS is configured
     OLS_DIRECTORY_STATUS FALSE   Determines if OID is enabled with OLS
     OLS_ENABLE_STATUS    TRUE    Determines if OLS is enabled

   • If you want to find the Oracle Label Security status of all PDBs in a multitenant environment, as a common user with administrative privileges, then query CDB_OLS_STATUS. For example:

     SELECT * FROM CDB_OLS_STATUS;
     
     NAME                 STATUS  DESCRIPTION                           CON_ID        
     -------------------- ------- ------------------------------------  ------
     OLS_DIRECTORY_STATUS FALSE   Determines if OID is enabled with OLS 4 
     OLS_ENABLE_STATUS    TRUE    Determines if OLS is enabled          4
     OLS_CONFIGURE_STATUS TRUE    Determines if OLS is configured       4
     OLS_DIRECTORY_STATUS FALSE   Determines if OID is enabled with OLS 5 
     OLS_ENABLE_STATUS    TRUE    Determines if OLS is enabled          5
     OLS_CONFIGURE_STATUS TRUE    Determines if OLS is configured       5
       

You can both register and enable Oracle Label Security from SQL*Plus.

1. Log into the database instance as user SYS with the SYSDBA administrative privilege.

   For example:

   sqlplus sys as sysdba
   Enter password: password 
   

2. If you are using a multitenant environment, then connect to the appropriate PDB.

   For example, to connect to the PDB hrpdb:

   CONNECT SYS@hrpdb AS SYSDBA
   Enter password: password
   

   To find the available PDBs, query the DBA_PDBS data dictionary view. To check the current PDB, run the show con_name command.

3. Register and enable Oracle Label Security as follows.

   EXEC LBACSYS.CONFIGURE_OLS; -- This procedure registers Oracle Label Security.
   EXEC LBACSYS.OLS_ENFORCEMENT.ENABLE_OLS; -- This procedure enables it.
   

4. Connect as user SYS with the SYSOPER privilege.

   CONNECT SYS AS SYSOPER -- Or, CONNECT SYS@hrpdb AS SYSOPER
   Enter password: password
   

5. Restart the database.

   For example:

   SHUTDOWN IMMEDIATE
   STARTUP

You can both register and enable Oracle Label Security using Database Configuration Assistant.

1. Start Database Configuration Assistant (DBCA).

   • UNIX: Run the following command:

     $ORACLE_HOME/bin/dbca
     

   • Windows: From the Start menu, click All Programs. Then click Oracle - ORACLE_HOME, then Configuration and Migration Tools, and then Database Configuration Assistant.

   The Welcome screen appears.

2. Click Next.

   The Operations screen appears.

3. Select Configure Database Options. Click Next.

   The Database screen appears.

4. From the list, select the database where you need to configure and enable OLS. Click Next.

   The Database Content screen appears.

5. Select Oracle Label Security. Click Next.

   The Connection Mode screen appears.

6. Select either Dedicated Server Mode or Shared Server Mode. Click Finish.

   A dialog box is displayed informing you that the operation will require the database to be restarted.

7. Click OK.

   A confirmation dialog box is displayed.

8. Click OK.

   The DBCA progress screen is displayed.

9. After the operation is complete, you are prompted to perform another operation. Click No to exit DBCA.

From Enterprise Manager Cloud Control, you use the Oracle Label Security pages to create and manage Oracle Label Security policies.

1. Ensure that you have configured the Cloud Control target databases that you plan to use with Oracle Label Security.

   See the Oracle Enterprise Manager online help for more information about configuring target databases.

2. Point your browser to the Cloud Control login page.

   For example:

   https://myserver.example.com:7799/em
   

3. Log into Cloud Control as user SYSMAN.
4. In the Cloud Control home page, from the Targets menu, select Databases.
5. In the Databases page, select the link for the database to which you want to connect.

   The Database home page appears.

6. From the Security menu, select Label Security.

   The Database Login page appears.

7. Enter the following information:

   • Username: Enter the user name of a user who has been granted the LBAC_DBA database role, or enter LBACSYS.

   • Password: Enter the password.

   • Role: Select NORMAL from the list.

   • Save As: Select this check box if you want these credentials to be automatically filled in for you the next time that this page appears. The credentials are stored in Enterprise Manager in a secured manner. Access to these credentials depends on the user who is currently logged in.

You can log in to Oracle Label Security from SQL*Plus if you have been granted the LBAC_DBA database role.

sqlplus psmith_ols -- Or, sqlplus psmith_ols@hrpdb for a PDB named hrpdb
