J Troubleshooting Oracle Database Vault

This appendix includes the following sections:

J.1 Using Trace Files to Diagnose Events in the Database

You can monitor your Oracle Database Vault database instance for server and background process events by checking the database instance trace files. Trace files reveal events such as the logic that the Oracle Database Vault security enforcement engine executes, as well as internal errors, block corruption errors, deadlock errors, administrative actions that may have occurred, values of parameters that had nondefault settings when the database instance started, and other information.

Be careful about enabling trace files, however. Doing so can increase the overhead of the database instance operation, which could decrease performance. Contact Oracle Support before you decide to enable tracing.

To enable tracing, log on with any account that has the ALTER SESSION privilege and issue the following statement:

SQL> ALTER SESSION SET EVENTS '47998 trace name context forever, level 12'

For example, suppose you have an account that is trying to use a statement that is protected by a command rule, but the statement is not working as expected. You can diagnose the enforcement logic for this account by granting it the ALTER SESSION privilege, issuing the ALTER SESSION statement, and then retrying the statement. Afterward, check the trace files to determine what is going on.

You can disable tracing by issuing the following statement:

SQL> ALTER SESSION SET EVENTS '47998 trace name context off'

For more information about how to manage trace files, see Oracle Database Administrator's Guide and Oracle Database Performance Tuning Guide.

J.3 Configuration Problems with Oracle Database Vault Components
