To configure BPMN process service engine properties:
Access this page through one of the following options:
|From the SOA Infrastructure Menu...||From the SOA Folder in the Navigator...|
The BPMN Service Engine Properties page displays properties for setting audit trail and large document thresholds, validating payload schema, and setting the audit trail level.
Make changes to the service engine properties that are appropriate to your environment.
Select one of the following options:
Note: If you do not want audit entries to be displayed, then you must turn off both the audit level and the metrics. If metrics are enabled, then audit entries are displayed even if the audit level is set to Off.
Audit Trail Threshold
Enter the maximum size in bytes of an instance audit trail before it is chunked and saved in a dehydration store table separate from the audit trail. If the threshold is exceeded, the View XML link is shown in the audit trail instead of the payload.
Large Document Threshold
Enter the maximum size of a generated document within a BPMN process component instance before it is stored in a separate table in the dehydration store.
Select to enable validation of inbound and outbound messages. Nonschema-compliant payload data is intercepted and displayed as a fault.
Note: This setting is independent of the SOA composite application and SOA Infrastructure payload validation level settings. If payload validation is enabled at both the service engine and SOA Infrastructure levels, data is checked twice: once when it enters the SOA Infrastructure, and again when it enters the service engine.
Disable BPMN Monitors and Sensors
Select this checkbox to disable all BPMN monitors and sensors defined for all BPMN components across all deployed SOA composite applications.
If you want to configure advanced BPMN properties in the System MBean Browser, click More BPMN Configuration Properties. Properties that display include the following. Descriptions are provided for each property.
AuditDetailThreshold: The maximum size (in bytes) an audit trail details string can be before it is stored separately from the audit trail.
AuditLevel: Controls the amount of audit events logged by a process; currently supported logging levels are:
off: absolutely no logging performed whatsoever; may result in a slight performance boost for processing instances.
AuditKeyExtents: The extent size for the BPMN Audit Query ID generation. This value specifies the amount by which the BPMN Audit Query sequence will increase each time a new set of IDs are requested.
AuditUpdateBatchSize: The batch size used when marking BPMN process audit information as aborted during undeployment.

LargeDocumentThreshold: The maximum size (in bytes) a BPMN variable can be before it is stored in a separate location from the rest of the instance scope data.
MaximumNumberOfInvokeMessagesInCache: Specify the number of invoke messages that can be kept in the in-memory cache, once the service engine reaches this limit, it pushes the message to dispatcher in-memory cache, instead it saves the message in the database, and these saved messages can be recovered using recovery job. Use value
-1 to disable this property.

true, indicates that this MBean is a System MBean.
TimeEstimationToBamUpdateInterval: The time interval in seconds in which the process instances estimated completion times are populated in BAM.
UserInitiateProcessCleanupAction: The action to be performed for the cleanup procedure:
OFF will disable the cleanup process on the next scheduled activation of the process.
UserInitiateProcessCleanupCronExpression: The cron type expression indicates when and how often the cleanup procedure should take place. Any changes to the schedule will take effect on the next scheduled activation of the cleanup process.
UserInitiateProcessCleanupRetentionDays: Only the user-initiated processes older than
number of days old will be processed. Zero is not allowed. Fractions of a day can be specified as a decimal.
UserInitiateProcessCleanupTaskStates: The task states to be considered during the cleanup procedure.
The UserInitiateProcessCleanup properties support the cleanup of properties created using the initiator task.

true, the service engine applies schema validation for incoming and outgoing XML documents. The default value
Version: Version of the configuration file.
Visible: If set to true, this MBean is visible to the current user.
Process monitor dashboards in Oracle Business Process Management Workspace allow you to monitor and optimize process execution by identifying bottlenecks and other performance problems.
To configure support for process monitor dashboards:
When a BPM composite with enabled measurements (either standard or user-defined) is created, composite specific derived physical and logical data objects are created in Oracle Business Activity Monitoring (Oracle BAM) 12c. These data objects have the columns for standard metrics and user-defined metrics.
Composite specific process physical derived data object
Display Name: oracle/processanalytics/<COMPOSITE>/Process (physical)
Composite specific activity physical derived data object
Display Name: oracle/processanalytics/<COMPOSITE>/Activity (physical)
Composite specific process logical data object
Display Name: oracle/processanalytics/<COMPOSITE>/Process
Composite specific activity logical data object
Display Name: oracle/processanalytics/<COMPOSITE>/Activity
In a BPM composite, if the user has defined Analytics View Identifier for the composite, then synonyms to composite specific physical data object views are generated. These views are used to get SQL access to process analytics data. The naming convention of the view synonyms are:
BPM_PV_PRCS_<IDENTIFIER>_V - composite specific process fact
BPM_PV_ACTV_<IDENTIFIER>_V - composite specific activity fact
<IDENTIFIER> is the Analytics View Identifier defined in the composite.
In addition to the creation of composite specific fact data objects in Oracle BAM 12c, the standard dimension data objects, such as
COMPOSITE_DEFINITION, ACTIVITY_DEFINITION, PROCESS_DEFINITION, TASK_DEFINITION, ROLE_DEFINITION, and so on, are also populated with appropriate metadata information from the composite.
To do this task, you use the Oracle Enterprise Manager Fusion Middleware Control.
To enable Oracle BPM Data Publish to Oracle BAM 12c:
To the right, set disableProcessMetrics to false. (Default is true.)
rocessMetrics target can be enabled only if an Oracle BAM 12c server is detected.
If a new BPM composite configured with measurement is deployed before enabling
ProcessMetrics, or when the Oracle BAM 12c server is down; then all data publishing to Oracle BAM 12c Process Star Schema from such composites is permanently disabled (even if Oracle BAM 12c comes up later). This is because some mandatory artifacts, required for allowing runtime analytics population, could not be created in Oracle BAM 12c during composite deployment time. In order to allow such composites to publish data to Oracle BAM 12c Process star schema, they must be redeployed when Oracle BAM 12c is up.
When a BPMN composite application is deployed, the following Oracle BAM data objects are generated automatically:
Data object for the following business indicator:
Once this is imported, you should rename it to:
This is created in the target folder. If the data object already exists, new columns are added to it, assuming the old columns match data types. Otherwise, an error is thrown.
COMPONENT, INTERVAL, COUNTER data objects if they are not present in the target folder.
The target Oracle BAM Server is specified by JNDI name parameter.
Data objects can be created only automatically at deployment. You cannot create them manually.
To configure Oracle BPM for use with Oracle BAM 11g, you perform these tasks:
You must configure the Oracle BAM Adapter to use either SOAP or RMI for communicating with Oracle BAM.
To configure the Oracle BAM adapter on Oracle BPM server:
The JNDI name used to configure the Oracle BAM adapter is used. For example, if you configured the Oracle BAM adapter to use SOAP, then the default JNDI name is eis/bam/soap. Similarly, if you configure the Oracle BAM adapter to use RMI, then the default JNDI name is eis/bam/rmi.
bam/Plan.xml, then complete the dialogs.
For more information about integrating Oracle BAM with Oracle SOA Suite composite applications, see Developing SOA Applications with Oracle SOA Suite.
To do this task, you use the Oracle Enterprise Manager Fusion Middleware Control.
To enable Oracle BPM data publish to Oracle BAM 11g Monitor Express:
To the right, set disableMonitorExpress to false. (Default is true.)
