For Oracle Database releases earlier than 12.1 using Oracle Label Security and Oracle Database Vault, you must run the OLS preprocess script before you upgrade.

If you are upgrading from a database earlier than Oracle Database release 12.1 that uses Oracle Label Security (OLS) and Oracle Database Vault, then you must first run the OLS preprocess script, olspreupgrade.sql, to process the aud$ table contents. The OLS upgrade moves the aud$ table from the SYSTEM schema to the SYS schema. The olspreupgrade.sql script is a preprocessing script required for this move.

The olspreupgrade.sql script creates a temporary table PREUPG_AUD$ in the SYS schema and moves the SYSTEM.aud$ records to SYS.PREUPG_AUD$. As a safety measure, Oracle recommends that you archive your audit trail before running the olspreupgrade.sql script. If Oracle Label Security is installed on your database, and you are upgrading from an earlier release, then you must run the OLS preprocess script before upgrading.

If Oracle Label Security is installed in the earlier release that you are upgrading, then grant the DV_PATCH_ADMIN role to SYS.

If Oracle Database Vault is not installed with your release 11.2 database, then you can skip steps 2, 3, 6, and 7 in this section.

To run the OLS preprocess script on a release 11.2 database before upgrading:

1. Copy the following scripts script from the newly installed Oracle home to the Oracle home of the database that y0u want to upgrade:

   • ORACLE_HOME/rdbms/admin/olspreupgrade.sql

   • ORACLE_HOME/rdbms/admin/emremove.sql

   • ORACLE_HOME/rdbms/admin/catnoamd.sql

2. Start SQL*Plus and connect as DVOWNER to the database that you want to upgrade.

3. Run the following statement:

   SQL> GRANT DV_PATCH_ADMIN to SYS;
   

4. At the system prompt, connect SYS as SYSDBA:

   CONNECT SYS AS SYSDBA
   

5. Run the preprocess scripts for Data Vault

   ORACLE_HOME/rdbms/admin/olspreupgrade.sql
   ORACLE_HOME/rdbms/admin/emremove.sql
   ORACLE_HOME/rdbms/admin/catnoamd.sql
   

   You may continue to run your applications on the database while the preprocess scripts are running.

6. After the olspreupgrade.sql completes its run successfully, start SQL*Plus and connect to the database as DVOWNER.

7. Run the following SQL statement:

   SQL> REVOKE DV_PATCH_ADMIN from SYS;
