This section describes troubleshooting and limitations for Oracle RAC Discovery.

Error Message

Description

Failed to lookup host name. No RAC CI will be created.

For one or more nodes, the job failed to retrieve the FQDN (fully qualified domain name) from the listeners listened_ips attribute information.

  • Check the logs to retrieve the IP and destination.

  • Make sure that the FQDN for that IP can be obtained either from the DNS or from the host file.

No RAC CI are retrieved.

Not all nodes were discovered with the correct listener information.

Discovery cannot discover links to the remote machines (database clients)

This can occur in the following situation: The discovered database reports its clients by their host names and not by their IP addresses, and the host name cannot be resolved to an IP address. In this case, the remote client cannot be created.
