D Upgrading from a Previous Version of Database Vault

D.1 Upgrading from a 10.2.0.x Version

Use the following steps to upgrade an Oracle Database Vault 10.2.0.x installation to Oracle Database Vault 10g Release 2 (10.2.0.4):

1. Re-create the password file with the nosysdba=n and force=y flags, to allow the SYS user to connect AS SYSDBA. Use the following syntax:

   orapwd file=$ORACLE_HOME/dbs/orapwSID password=password force=y nosysdba=n
   
   

   Here SID is the Oracle system identifier (SID) of the database and password is the password for the SYS account.

2. Shut down the database.

   To stop a single-instance database, use the following commands:

   sqlplus SYS "AS SYSDBA"
   Enter password:
   SQL> shutdown immediate
   
   

   For an Oracle Real Application Clusters (RAC) database, use the following command:

   $ORACLE_HOME/bin/srvctl stop database -d db_name  -c "SYS/password AS SYSDBA"
   
   

   Here db_name is the name of the database.

3. Relink the Oracle executable to turn off the Oracle Database Vault option. Use the following commands:

   cd $ORACLE_HOME/rdbms/lib
   make -f ins_rdbms.mk dv_off
   cd $ORACLE_HOME/bin
   relink oracle
   

   Note:

   For an Oracle Real Application Clusters (RAC) database, you must repeat the preceding commands on all nodes.

4. Start the database. For a single-instance database, use the following commands:

   sqlplus SYS "AS SYSDBA"
   Enter password:
   SQL> startup
   
   

   For an Oracle Real Application Clusters (RAC) database, use the following command:

   $ORACLE_HOME/bin/srvctl start database -d db_name 
   
   

5. Unlock the DVSYS account as the SYS user:

   sqlplus SYS "AS SYSDBA"
   Enter password:
   SQL>ALTER USER DVSYS ACCOUNT UNLOCK;
   
   

6. Run Oracle Database Vault Configuration Assistant (DVCA) by using the dvca -action disable option. This disables the Database Vault triggers. Use the following syntax:

   dvca -action disable 
        -service service_name 
        -owner_account DV_owner_account_name 
       [-logfile ./dvca.log] 
       [-nodecrypt] 
   
   Enter SYS password: sys_password
   Enter owner password: owner_password
       
   
   

   Here:

   • -action is the action to perform. In this case the action is disable.

   • -service is the database service name.

   • -owner_account is the Oracle Database Vault Owner account name.

   • -logfile is an optional flag to specify a log file name and location. You can enter an absolute path, or enter a path that is relative to the location of the $ORACLE_HOME/bin directory.

   • -nodecrypt is the option to read plaintext passwords.

7. Install the Oracle Database Release 10.2.0.4 Patch Set.

   See Also:

   "Apply Oracle Database Release 10.2.0.4 Patch Set" for more information about installing the patch set

8. Restart the database. For a single-instance database, use the following commands:

   sqlplus SYS "AS SYSDBA"
   Enter password:
   SQL> shutdown immediate
   SQL> startup
   
   

   For an Oracle Real Application Clusters (RAC) database, use the following command:

   $ORACLE_HOME/bin/srvctl stop database -d db_name 
   $ORACLE_HOME/bin/srvctl start database -d db_name 
   
   
   

9. Connect AS SYSDBA and run the following SQL statements:

   SQL> DROP FUNCTION DVSYS.REALM_SDML_AUTHORIZED ;
   SQL> DROP PROCEDURE DVSYS.SYNCHRONIZE_POLICY_FOR_OBJECT;
   SQL> DECLARE
             CURSOR stmt IS
                      select u.name, o.name, r.pname
                          from user$ u, obj$ o, rls$ r
                      where u.user# = o.owner#
                          and r.obj# = o.obj#
                          and bitand(r.stmt_type,65536) > 0;
   
                      object_schema VARCHAR2(32) := NULL;
                      object_name VARCHAR2(32) := NULL;
                      policy_name VARCHAR2(32) := NULL;
   
                      BEGIN
                       OPEN stmt;
                         LOOP
                              FETCH stmt INTO object_schema, object_name, policy_name;
                              EXIT WHEN stmt%NOTFOUND;
                              dbms_rls.drop_policy('"'||object_schema||'"',
                              '"'||object_name||'"',
                              '"'||policy_name||'"');
                         END LOOP;
                       Close stmt;
                      END;
                     /
   
   

10. Run DVCA to reconfigure Database Vault. Use the following syntax:

    $ORACLE_HOME/bin/dvca -action option -oh oracle_home -jdbc_str
    jdbc_connection_string -owner_account DV_owner_account_name 
    [-acctmgr_account DV_account_manager_account_name]
    [-logfile ./dvca.log] [-nodecrypt]
    
    

    Where:

    • action: The action to perform. option creates the Database Vault schema objects, creates the DV_OWNER account and the optional DV_ACCTMGR account, and deploys the Database Vault Administrator application.

    • oh: The Oracle home for the database.

    • jdbc_str: The JDBC connection string used to connect to the database. For example, jdbc:oracle:oci:@orcl1, where orcl1 is the net service name in the tnsnames.ora file ($ORACLE_HOME/network/admin/tnsnames.ora).

    • owner_account: Oracle Database Vault Owner account name

    • acctmgr_account: (Optional) Oracle Database Vault Account Manager user

    • logfile: Optionally, specify a log file name and location. You can enter an absolute path or a path that is relative to the location of the $ORACLE_HOME/bin directory

    • nodecrypt: Reads plaintext passwords as passed on the command line. You must use this option if you are passing plaintext passwords to the command.

    Note:

    You are prompted to enter the SYS, Database Vault Owner, and Database Vault Account Manager passwords.

    See Also:

    Appendix C, "Running DVCA After Creating a Database Vault Database" for more options available with the dvca -action option command

11. Run Oracle Database Vault Configuration Assistant (DVCA) by using the dvca -action enable option. This enables the Database Vault triggers. Use the following syntax:

    dvca -action enable 
         -service service_name 
         -owner_account DV_owner_account_name  
        [-logfile ./dvca.log] 
        [-nodecrypt] 
    
    Enter SYS password: sys_password
    Enter owner password: owner_password
        
    
    

    See Step 6 for details of the options used in the command.

12. Lock the DVSYS account. Use the following SQL statements:

    SQL> CONNECT SYS "AS SYSDBA"
    Enter password:
    SQL> ALTER USER DVSYS ACCOUNT LOCK;
    
    

13. Shut down the database.

    To stop a single-instance database, use the following commands:

    sqlplus SYS "AS SYSDBA"
    Enter password:
    SQL> shutdown immediate
    
    

    For an Oracle Real Application Clusters (RAC) database, use the following command:

    $ORACLE_HOME/bin/srvctl stop database -d db_name 
    
    

    Here db_name is the name of the database.

14. Relink the Oracle executable to turn on the Oracle Database Vault option. Use the following commands:

    cd $ORACLE_HOME/rdbms/lib
    make -f ins_rdbms.mk dv_on
    cd $ORACLE_HOME/bin
    relink oracle
    

    Note:

    For an Oracle Real Application Clusters (RAC) database, you must repeat the preceding commands on all nodes.

15. Start the database. For a single-instance database, use the following commands:

    sqlplus SYS "AS SYSDBA"
    Enter password:
    SQL> startup
    
    

    For an Oracle Real Application Clusters (RAC) database, use the following command:

    $ORACLE_HOME/bin/srvctl start database -d db_name 
    
    
    

16. If you wish to disable connections with SYSDBA privileges, then re-create the password file with the nosysdba=y and force=y flags. Use the following syntax:

    orapwd file=$ORACLE_HOME/dbs/orapwSID password=password force=y nosysdba=y
    
    

    Here SID is the Oracle system identifier (SID) of the database and password is the password for the SYS account.
