15.1 Monitoring Oracle Mediator Service Component Instances and Faults

You can monitor Oracle Mediator service component recent instances and faults. Each service component in a SOA composite application has its own instance ID. These IDs are different from the overall instance ID of the SOA composite application of which each service component is a part. To monitor Oracle Mediator service component instances and faults: 1. Access this page through one of the following options:

2. In the Component Metrics section, select the Oracle Mediator service component.

3. Click Dashboard.

From the SOA Infrastructure Menu... From the SOA Folder in the Navigator... 1. Select Home. 2. Select the Deployed Composites tab. 3. In the Composite section, select a specific SOA composite application. 1. Expand soa-infra, and then select a specific SOA composite application. 15-2 Oracle Fusion Middleware Administrators Guide for Oracle SOA Suite and Oracle BPM Suite The Dashboard page displays the following information: ■ Recent instances of the Oracle Mediator service component, including the instance ID, the state of the instance for example, completed successfully or faulted, the start time, the last modification time, the source event or operation that triggered the instance, and logs describing the instance. ■ Recent faults in the Oracle Mediator service component, including the error message, whether you can recover from the fault, the time at which the fault occurred, the instance ID of the service component, the activity in which the fault occurred, and logs describing the fault. ■ Routing statistics for the Oracle Mediator service component, including the number of successfully processed messages, faulted messages, and incoming messages, as well as the average processing times for successful messages and faulted messages. ■ The instance processing rate per minute or throughput for the past five minutes, including total throughput, throughput for successful message, and throughput for faulted messages. This appears in graphic format, and you can also view the information as a table.

4. In the Recent Instances section, perform the following tasks:

a. In the Instance ID column, click an instance ID to view its instance details,

including an audit trail and faults. Monitoring Oracle Mediator Service Components and Engines 15-3

b. In the Logs column, click a log icon to access the Log Messages page with

messages specific to that instance.

c. Click Show Only Running Instances to view only those instances that are in

the running state.

d. Click Show All below the section to access the Instances page of the service

component and view all instances of the service component.

5. In the Recent Faults section, perform the following tasks:

a. In the Error Message column, click an error message to display complete

information about the fault. If the fault is identified as recoverable, click Recover Now to perform fault recovery.

b. In the Recovery column, click a fault identified as Recoverable to perform

fault recovery at the service component instance level.

c. In the Logs column, click a specific log to access the Log Messages page with

filtered messages specific to that instance.

d. Click Show only system faults to display only the faults that were caused by a

system error. System faults are related to system failure issues, such as a database or network being inaccessible.

e. Click Show All below the section to access the Faults page of the service

component and view all component faults.

6. Expand the Routing Statistics section and select an operation or event in the

Select Route Source field. View the statistics for the selected operation or event. To view additional information, expand the Route Target section.

7. Expand the Instance Rate per Min Real-Time Data section to view a graphical

representation of the number of successful, faulted, and incoming pending instances of the BPEL process service component over a specific time range. Click Table View to display the same information in a tabular format. 15-4 Oracle Fusion Middleware Administrators Guide for Oracle SOA Suite and Oracle BPM Suite For more information, see Section 1.2.3, Introduction to SOA Composite Application Instances .

15.1.1 Introductions to the Sections of the Dashboard Page

This section describes the instance information sections of the Dashboard page. Recent Instances Section This section provides the following information about the recent Oracle Mediator service component instances: ■ Instance ID : The unique ID of a specific Oracle Mediator service component instance. ■ State : The state of the specific Oracle Mediator service component instance. The possible states are described below. – Stale : The composite for which this Oracle Mediator instance was created is undeployed. – Terminated by User : The instance was terminated manually through Oracle Enterprise Manager Fusion Middleware Control, or automatically by a fault policy. – Faulted : The instance is faulted and cannot be recovered. – Completed successfully : Everything is fine with this instance and it ran successfully. – Recovery required : The instance is faulted and can be recovered manually through Oracle Enterprise Manager. For more information about recovering a fault, see Section 16.2, Managing Oracle Mediator Faults . – Running : One or more routing rules of the Oracle Mediator service component are still running. ■ Start Date : The date when the specific Oracle Mediator service component instance was started. ■ Last Modified Date : The date when the specific Oracle Mediator service component instance was last modified. ■ Source : The operation or event that triggered the Oracle Mediator service component instance. ■ Logs : The location of the log file containing the log messages related to the Oracle Mediator service component instance. Monitoring Oracle Mediator Service Components and Engines 15-5 Recent Faults Section This section provides the following information about the recent faults that occurred while the Oracle Mediator service component was running: ■ Error Message : The detailed error message associated with the faulted instance. ■ Recovery : An indicator of whether the fault is recoverable or not. If a fault is marked as recoverable, you can select it and choose a recovery action from the Recovery Actions list. You can also click Recover for that fault to access more recovery options at the service component instance level. ■ Fault Time : The time when the fault occurred in the Oracle Mediator service component instance. ■ Component Instance ID : The unique ID of the Oracle Mediator service component instance. ■ Case : The routing source case where the fault occurred. ■ Logs : The log file containing the log message related to the fault. Click this link to see more details about the fault and potential causes of the fault. For more details about the information available on the Faults page, see Section 16.2, Managing Oracle Mediator Faults . Routing Statistics Section This section provides the following information about the routing data of a source operation or subscribed event. ■ Number of Successfully Processed Messages : The number of messages successfully processed for the selected route source. ■ Number of Faulted Messages : The number of messages that threw faults for the selected route source. ■ Number of Incoming Messages : The total number of incoming messages for the selected route source. ■ Average Processing Time for Successful Messages : The average time taken to process each successful message for the selected route source. ■ Average Processing Time for Faulted Massages -The average time taken to process each faulted message. The Route Target subsection in the Routing Statistics section displays statistics of the target routes for the Oracle Mediator service component. This section provides the following information about an Oracle Mediator service component instance: ■ Name : The name of the route target of the Oracle Mediator service component. ■ Error : The number of errors that occurred during routing. ■ Average Processing Time : The average processing time for the instances of the Oracle Mediator service component. This field has two subfields, Success and Failure . The Success subfield shows the average processing time for the instances of the Oracle Mediator service component that were processed successfully. The Failure subfield shows the average processing time for the instances of the specific Oracle Mediator service component that failed to process successfully. ■ Average Invocation Time : The average invocation time for the instances of the Oracle Mediator service component.
