A Disabling and Enabling Oracle Label Security

This appendix contains:

Note:

Oracle does not support the deinstallation of Oracle Label Security.

When You Must Disable 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.

Checking if Oracle Label Security Is Enabled or Disabled

To find if Oracle Label Security has been enabled or disabled, query the V$OPTION data dictionary view. Any user can query this view. If Oracle Label Security is enabled, then the query returns TRUE. Otherwise, it returns FALSE. Remember that the PARAMETER column value is case sensitive. For example:

SELECT VALUE FROM V$OPTION WHERE PARAMETER = 'Oracle Label Security';

Disabling Oracle Label Security

If Oracle Database Vault has been enabled, then do not disable Oracle Label Security. See Oracle Database Vault Administrator's GuideOpens a new window to find if Database Vault has been enabled.

  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.
