TNS listener port. This results in the software detecting the nonexistent Oracle instance and
displaying it in the topology. Refer to Oracle documentation for information on how to remove the
deleted Oracle instance from the TNS listener port.
Requirements for Discovering Oracle
To discover Oracle:
• The management software for Oracle must be installed. For information about installing the
management software for Oracle, refer to the Installation Guide.
• By default, the software sets the TNS Listener Port to 1521. If you use another port, you can
change the port number on the Discovery Targets tab.
• Oracle discovery relies on the TNS networking substrate on which Oracle is built (TNS is
Oracle's proprietary protocol). The software does not use TNS listener password. If you have set
a TNS Listener password, the software is not able to discover the Oracle instances serviced by
the listener.
Do Not Run Overlapping Discovery Schedules
If you are creating multiple Discovery schedules, care must be taken to avoid scheduling
conflicts—concurrently scheduled Discovery tasks—and that each scheduled task has enough time
to start and finish before the next Discovery task is scheduled to start. For example, if a scheduled
Discovery is still in progress when another scheduled Discovery attempts to start, the Discovery task
that attempts to start will not start because the first Discovery is still running. The Discovery that is
unable to start is re-scheduled according to its recurring rule. If the Discovery task is scheduled to
run on a daily basis for example, then the Discovery will start again on the next day. To check the
status of scheduled Discovery tasks, view the appiq.log file in the following directory:
[Install_Dir]\jbossandjetty\server\appiq\logs
"This storage system uses unsupported
firmware. ManagementClassName: ???"
