6000000000001000 - SSH tunnel not established

One or more SSH tunnels has been enabled in the past, but the cron job was not able to re-establish the SSH tunnel with all of the Authorized PDBA Client IP addresses.

Recovery

• Verify that the Customer Provisioning Application (CPA) machine is up and running.
  • If the CPA machine is not running, restart it and wait for the alarm to clear.
  • If the CPA machine is running, or if the alarm does not clear, contact My Oracle Support (MOS).
• If the alarm text is "SSH tunnel down for <IP>", verify that the port specified for SSH tunneling is not in use on the remote machine.
