Oracle Application Servers

Creating a new Oracle monitor

Supported Versions: Applications Manager supports monitoring of Oracle Application Servers 10g.

Prerequisites: Applications Manager uses the Dynamic Monitoring Service (DMS) provided by Oracle Application Server to monitor the same. For this reason, the DMS Servlet has to be made accessible to the system where the Applications Manager is running. Refer Prerequisites section.

To create a Oracle Application server monitor, follow the steps given below:

  1. Click on New Monitor link.
  2. Select Oracle AS.
  3. Enter the IP Address or hostname of the host where Oracle Application Server runs.
  4. Enter the SubNetMask of the network.
  5. Enter the Port number for eg., 7200.
  6. If you are adding a new monitor from an Admin Server, select a Managed Server.
  7. Choose the Monitor Group from the combo box with which, you want to associate Oracle Application Server Monitor (optional). You can choose multiple groups to associate your monitor.
  8. Click Add Monitor(s). This discovers Oracle Application Server from the network and starts monitoring them.

Monitored Parameters

Oracle Application servers are monitored based on the attributes listed below. The monitoring details of Oracle Application server are represented graphically that helps to understand the parameters with ease. You can also configure thresholds to the attributes monitored by the server based on these details.

  • Availability tab gives the Availability history for the past 24 hours or 30 days.
  • Performance tab gives the Health Status and events for the past 24 hours or 30 days.
  • List view enables you to perform bulk admin configurations.
