A Disabling and Enabling Oracle Label Security

You may need to disable Oracle Label Security to perform upgrade tasks or correct erroneous configurations.

Another reason for disabling Oracle Label Security is if you want to test an application without enforcing Oracle Label Security. You can reenable Oracle Label Security after you complete the tasks.

If Oracle Database Vault has been enabled, then do not disable Oracle Label Security.

1. Log into the database instance as user SYS or a user who has been granted the LBAC_DBA role.

   For example:

   sqlplus psmith_ols -- Or, psmith_ols@hrpdb for the hrpdb pluggable database (PDB)
   Enterp password: password
   

2. Run the following procedure:

   EXEC LBACSYS.OLS_ENFORCEMENT.DISABLE_OLS;
   

3. Restart the database.

   For example:

   CONNECT SYS AS SYSOPER
   Enter password: password
   
   SHUTDOWN IMMEDIATE
   STARTUP
   

4. For Oracle Real Application Cluster (Oracle RAC) environment or a multitenant environment, repeat these steps for each Oracle RAC node or PDB on which you enabled Oracle Label Security.

You can enable Oracle Label Security in SQL*Plus.
