4 Monitoring the SOA Infrastructure

This chapter describes how to monitor the Oracle SOA Suite routing topology, SOA Infrastructure performance summary metrics, recent instances and faults, deployed SOA composite applications, message delivery processing requests, and service and reference binding components in the SOA Infrastructure. All SOA composite applications are deployed to the SOA Infrastructure. It also describes how to display details about BPEL process messages that require recovery and how to access the Recovery page of the BPEL process service engine to perform message recovery.

This chapter includes the following sections:

For more information, see Section 1.2.1, "Introduction to the SOA Infrastructure Application."

4.1 Discovering the Oracle SOA Suite Routing Topology

The Topology Viewer is useful for when you are tasked to administer an existing Oracle SOA Suite environment. The Topology Viewer quickly provides you with a graphical representation of the deployed resources (servers, databases and data sources, SOA composite applications, and so on) and their relationships.

The Topology Viewer shows the routing relationships across components and elements. The Topology Viewer enables you to discover your Oracle Enterprise Manager Fusion Middleware Control environment and identify how requests are routed across components.

For example, you can use the Topology Viewer to understand the following:

  1. Above the navigator, click Topology.

4.3 Monitoring SOA Infrastructure Recent Instances and Faults and Deployed Composites

You can monitor the SOA composite applications deployed to the SOA Infrastructure.

To monitor SOA Infrastructure recent instances and faults:

  1. Access this page through one of the following options:

    From the SOA Infrastructure Menu... From the SOA Folder in the Navigator... From the SOA Composite Menu...
    1. Select Home.

    1. Select soa-infra.

    1. Select SOA Infrastructure.


    The upper part of the SOA Infrastructure Dashboard page displays the following details:

    • A message indicating that the retrieval of recent instances and faults that are displayed on this page is restricted to the specified time period. This message is displayed if the Restrict display of instances and faults to the last time_period checkbox is selected on the SOA Infrastructure Common Properties page (it is selected by default). The default time period value is 24 hours, but you can change this value. If this checkbox is not selected, all instances and faults (including count metrics) in the SOA Infrastructure since the last purging are displayed.

    • Recent SOA composite application instances, instance IDs, and starting times. By default, only running instances are shown.

    • The status of deployed SOA composite applications and their revision numbers, the number of instances created for each application, and the number of faulted instances in each application. The total number of deployed composites also is displayed in parentheses next to the Show More link.

    • Recent faults and rejected messages, including the error message, whether you can recover from the fault, the time at which the fault occurred, the SOA composite application in which the fault occurred, the location of the fault (service binding component, service component, or reference binding component), the instance ID of the SOA composite application, and a link to log messages describing the fault or rejected message. You can recover from faults identified as recoverable at the SOA Infrastructure, SOA composite application, service engine, and service component levels.

      If messages are awaiting recovery from the Recovery page of the BPEL process service engine, a message is displayed at the top of each SOA Infrastructure home page.

    Description of gs_soahomepage.gif follows
    Description of the illustration gs_soahomepage.gif

    Note:

    After the SOA Infrastructure is started, it may not be completely initialized to administer incoming requests until all deployed composites are loaded. During SOA Infrastructure initialization, a warning message is displayed at the top of the SOA Infrastructure home page. Do not perform operations such as composite deployment, composite undeployment, and others while this message is displayed. For more information, see Section 3.2.1, "Waiting for SOA Infrastructure Startup Initialization to Complete."

  2. If BPEL process messages require recovery from the Recovery page of the BPEL process service engine, the BPEL Message Recovery Required message is displayed at the top of each SOA Infrastructure home page.

    Description of bp_bpel_message_recov.gif follows
    Description of the illustration bp_bpel_message_recov.gif

    The display of this message recovery information is controlled by the bpelRecoveryStatus, excludeBpelMaxCreationTime, and bpelRecoveryAlertDurationInDays keys of the AuditConfig property in the System MBean Browser. This property is accessible from the More SOA Infra Advanced Configuration Properties section of the SOA Infrastructure Common Properties page. By default, these keys have the following values:

    • bpelRecoveryStatus is set to All.

    • excludeBpelMaxCreationTime is set to exclude the display of messages requiring recovery in the last five minutes.

    • bpelRecoveryAlertDurationInDays is set to only show the BPEL Message Recovery Required warning message when recoverable BPEL messages have been created in the last seven days.

    1. Perform the following tasks:

      Click This Link... To...

      Show Details

      View a message showing the number of invoke, callback, and activity messages that require recovery from the Recovery page of the BPEL process service engine. Manual recovery is not required if automatic recovery of BPEL messages is enabled. In that case, only exhausted messages must be manually recovered. Click Refresh to recalculate the number of invoke, callback, and activity messages requiring recovery.

      Go to BPEL Recovery Console

      Access the Recovery page of the BPEL process service engine to perform message recovery.

      You can also access the Recovery page later by selecting Service Engines > BPEL from the SOA Infrastructure menu and clicking the Recovery tab in the resulting page.

      Set Time Threshold

      View a message showing the time period for excluding messages that require recovery. By default, this setting excludes the last five minutes of messages. This value is controlled by the excludeBpelMaxCreationTime key of the AuditConfig property on the SOA Infrastructure Common Properties page. To change this value, click Yes to access this property in the System MBean Browser.

      Disable Alert

      View a message enabling you to prevent the display of this message recovery information on the Dashboard page. If you click Yes, this message recovery information is not displayed.

      To display this information again on the Dashboard page, set the bpelRecoveryStatus key to All for the AuditConfig property in the More SOA Infra Advanced Configuration Properties section of the SOA Infrastructure Common Properties page. For more information, see Section 3.1, "Configuring SOA Infrastructure Properties."


  3. In the Recent Composite Instances section, perform the following tasks:

    1. Click the Number of Instances link to display a message showing the numbers of running and total instances in the SOA Infrastructure. The link is not displayed by default. To enable this link to be displayed, select the Disable fetching of instance and fault count metrics. Each metric can still be retrieved on demand checkbox in the SOA Infrastructure Common Properties page.

      If you selected the Restrict display of instances and faults to the last time_period checkbox on the SOA Infrastructure Common Properties page and specified a time period or accepted the default value of 24 hours, the numbers of running and total instances in the SOA Infrastructure for that time period are displayed. If you did not select this checkbox, all instances and faults in the SOA Infrastructure since the last purging are displayed. Click Recalculate to recalculate the numbers.

    2. In the Instance ID column, click a specific instance ID to show the message flow through the various service components and binding components.

    3. In the Composite column, click a specific SOA composite application to access its home page.

For more information, see the following sections:

4.4 Monitoring Message Delivery Processing Requests

You can monitor SOA Infrastructure message delivery processing requests. These are metrics for the message delivery between the service engines, service infrastructure, and binding components. Once a message is handed over to a service engine, the amount of time it takes to process that message (instance processing time) is not captured in these metrics.

To monitor message delivery processing requests:

  1. Access this page through one of the following options:

    From the SOA Infrastructure Menu... From the SOA Folder in the Navigator...
    1. Select Monitoring > Request Processing.

    1. Right-click soa-infra.

    2. Select Monitoring > Request Processing.


    The Request Processing page enables you to monitor the following details:

    • The average request processing time for both synchronous and asynchronous messages, active requests, requests processed, and faulted requests in the service engines and service infrastructure.

    • The average request processing time, requests processed, and errors occurring in service (inbound) and reference (outbound) binding components.

    Description of soainfra_requestproc.gif follows
    Description of the illustration soainfra_requestproc.gif

  2. In the Service Engines section, click a specific service engine (for example, BPEL Engine) to access details such as recent instances using this service engine, components using this service engine, and recent fault occurrences.

For more information, see the following sections:

4.5 Monitoring Service and Reference Binding Components in the SOA Infrastructure

You can monitor all service and reference binding components used in all SOA composite applications deployed to the SOA Infrastructure. Services provide the outside world with an entry point to the SOA composite application. The WSDL file of the service advertises its capabilities to external applications. References enable messages to be sent from the SOA composite application to external services in the outside world.

To monitor service and reference binding components in the SOA Infrastructure:

  1. Access this page through one of the following options:

    From the SOA Infrastructure Menu... From the SOA Folder in the Navigator...
    1. Select Services and References.

    1. Right-click soa-infra.

    2. Select Services and References.


    The Services page displays details about the names and types of the services, the SOA composite applications in which the services are used, the partitions in which the SOA composite applications are deployed, the total number of messages processed, the average processing time, and the number of faults occurring in the services.

    Description of sca_services.gif follows
