“Connection to the Database Server Failed” Error
If you received an error message resembling the following after getting all element details, verify
that the database instance is running:
The connection to the database server failed. Check that the Oracle instance
'OIQ3 on host '192.168.1.162:1521 is running correctly and has the
management software for Oracle installed correctly.
Assume you received the error message listed above. You would want to verify the following:

of the installation's tasks is to create an APPIQ_USER user account with enough privileges for the
software to view statistics from the database.
Once you have verified these items, run Discovery Data Collection again. If you continue to see the
error message, contact customer support.
