Chapter 3: Operations 35

Without Maintenance Mode, this normal scenario might pose a problem.

Consider administrative tasks that the DBA needs to conduct while the

database is executing, but the Solution Pack probes are disabled. For

example, you may need to apply a patch where manual database startup

and shutdown need to occur but without action being taken by the

Solution Pack due to probe failures.

When a Virtual Oracle Service is in Maintenance Mode, the following

conditions are true:

• Probes always return success.

• The VHOST associated with the Virtual Oracle Service is active.

The following four screen shots show the following:

1. Placing the sample PROD Virtual Oracle Service into Maintenance

Mode.

2. Using sqlplus to shut the database down.

3. Using sqlplus to restart the database.

4. Connecting through the VHOST via SQL*Net.
