Using the BPEL Designer and Service Engine

Runtime Property Descriptions

The following table include descriptions for the BPEL Service Engine runtime properties

Property Name 

Description 

Default Value 

General Properties

Description 

Description of the JBI Component 

This is a bpel service engine. 

Name 

Name of the JBI Component. Specifies a unique name in the JBI environment. If you are installing more than one BPEL Service Engine in a JBI environment, make sure that each is unique. This can be changed in the descriptor (jbi.xml) for the component. When the service unit deploys the component, it is matched with target component name defined in its descriptor – jbi.xml 

sun-bpel-engine 

State 

State of the JBI Component. Started, Stopped, or Shutdown 

Started 

Type 

Type of the JBI Component (service-engine or binding-component) 

service-engine 

Identification Properties

Build Number 

Date and time stamp for the current build 

<build_number> 

Spec Version 

BPEL specification fully supported by this build 

<spec_version> 

Configuration

Debug Enabled 

Specifies whether the debugger can be used. A Selected the checkbox indicates that you can attach the debugger and debug the business process definition 

Select the checkbox to enable. The default is unchecked 

Debug Port 

Specifies the port number at which the BPEL Service Engine listens for the debugger UI to connect. The default value is sufficient in most cases. If more than on instance of the BPEL Service Engine is running on the same computer, make sure that unique, non-conflicting ports are assigned to each. Do not allow other applications to use these assigned ports 

3343 

Persistence Enabled 

When the checkbox is checked, persistence is enabled. The BPEL Service Engine persists the state of the business process instance at the configured data source for recovery in the event of a crash 

Select the checkbox to enable. The default is unchecked 

Non XA Data Source Name 

Specifies the non-XA data source where the BPEL Service Engine persists the state of the business process, to be used for recovery in the event of a crash 

Example: jdbc/bpelseNonXA 

XA Data Source Name 

Specifies the XA data source where the BPEL Service Engine persists the state of the business process, to be used for recovery in the event of a crash 

Example: jdbc/bpelseXA 

Number of Threads 

Specifies the number of threads allowed to execute BPEL definitions. Configure this to equal the number of CPUs for the system to achieve maximum throughput 

10 

Lease Renewal Interval 

This property is only used for clustered environments. It specifies the interval (in seconds) at which the BPEL Service Engine renews its lease to continue to own the business process instance it is currently executing 

60 (seconds) 

Life Span of Waiting Request 

Specifies the life span of a request after it is received. If the request is not consumed within the specified time, the BPEL Service Engine responds with an error for that request. The time is specified in seconds. A value of "0" indicates that the life span is indefinite 

Monitoring Enabled 

Specifies whether the Service Engine business process instance and activities at the configured data source are monitored 

Select the checkbox to enable. The default is unchecked 

Monitoring Variable Enabled 

Specifies whether the Service Engine enables changes to the monitoring variable value at the configured data source. This property is only applicable when Monitoring Enabled is checked 

Select the checkbox to enable. The default is unchecked 

KPI Enabled 

Specifies whether the Service Engine posts real-time KPI (key performance indicator) events 

Select the checkbox to enable. The default is unchecked 

Transformation Engine 

Specifies which transformation processor is used to execute XSL stylesheets. The choices are XSLT_1_0 and XSLT_2_0 

XSLT_1_0

Avg. D.C. Time 

The average message exchange delivery channel time in milliseconds 

Avg. Msg. Service Time 

The average message exchange message service time in milliseconds 

Avg. Response Time 

The average message exchange response time in milliseconds 

Completed Exchnges 

The total number of completed exchanges

Received Dones 

The total number of received dones 

Received Errors 

The total number of received errors 

Received Faults 

The total number of received faults 

Received Replies 

The total number of received replies 

Received Requests 

The total number of received requests 

Sent Dones 

The total number of sent dones 

Sent Errors 

The total number of sent errors 

Sent Faults 

The total number of sent faults 

Sent Replies 

The total number of sent replies 

Sent Requests

Loggers

Specifies the user-designated level of logging for each event. 

Each logger can be set to record information at any of the following levels:

  • FINEST: provides highly detailed tracing

  • FINER: provides more detailed tracing

  • FINE: provides basic tracing

  • CONFIG: provides static configuration messages

  • INFO: provides informative messages

  • WARNING: messages indicate a warning

  • SEVERE: messages indicate a severe failure

  • OFF: no logging messages
