Table A-4 Missing Properties Error and Workaround

Problem Workaround
Empty target property version The target is not properly configured or is unavailable. Reconfigure the target or check for metric collection errors.
Inadequate or incomplete target information collected by Oracle Management Agent. Recompute the dynamic properties and refresh the host configuration so that the Management Repository is updated with the latest configuration of the host.
  1. To recompute the dynamic properties:
    1. Stop and restart the Management Agent (easiest method, incurrs in downtime).
      emctl stop agent
emctl start agent

      Note:

      For clusters restart the Management Agent on all nodes.
    2. Reload the dynamic properties of all the targets (preferred method avoids blackouts or downtime).
      1. View the list of targets that are monitored by the Management Agent:
        emctl config agent listtargets
      2. Reload the dynamic properties of a specific target:
        emctl reload agent dynamicproperties [<Target_name>:<Target_Type>]
  2. To update the Management Repository with the latest configuration information, from the Enterprise menu, select Configuration, and then select Refresh Host Configuration. On the Refresh Host Configuration page, select the hosts for which the configuration must be updated, and click Refresh Hosts.
Targets are not properly discovered because of inadequate or incomplete target information collected during discovery. Rediscover the domain so all the targets are re-discovered effectively.
  1. Log in to the Domain Home page using appropriate credentials. For example, Farm01_base_domain.
  2. On the domain home page go to the Farm menu, select Refresh WebLogic Domain, and click Ok on all following pages to complete the process. After successful completion of the process the domain home page is refreshed with the targets discovered.
