3.5.1 MxDB-Oracle-HiAv Installation and Administration Guide

Chapter 2: Operations 36

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 MxDB-Oracle-HiAv 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

MxDB-Oracle-HiAv due to probe failures.

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

conditions are true:

• Probes always return success.

• The virtual host associated with the Virtual Oracle Service is active.

The next four screen shots show the following:

1. Placing the sample PROD Virtual Oracle Service into Maintenance

Mode.

2. Using SQL*Plus to shut the database down.

3. Using SQL*Plus to restart the database.

4. Connecting through the virtual host via SQL*Net.
