Oracle BAM Sensor 的enable batching属性

You can create sensor actions in Oracle BPEL Process Manager to publish sensor data into existing data objects on an Oracle BAM Server. When you create the sensor action, you can select an Oracle BPEL Process Manager variable sensor or activity sensor to get the data from and the data object in Oracle BAM Server in which you want to publish the sensor data.

The Oracle BAM Adapter supports batching of operations, but behavior with batching is different from behavior without batching. As the Oracle BAM Adapter is applied to BPEL sensor actions, the Oracle BAM sensor action is not part of the BPEL transaction. When batching is enabled, BPEL does not wait for an Oracle BAM operation to complete. It is an asynchronous call.

When batching is disabled, BPEL waits for the Oracle BAM operation to complete before proceeding with the BPEL process, but it does not roll back or stop when there is an exception from Oracle BAM. The Oracle BAM sensor action logs messages to the same sensor action logger as BPEL.

 

 

If batching is enabled, performance is dramatically improved, but there is no transaction guarantee. The BPEL process continues to run without waiting for the data to get to the Oracle BAM Server.

If batching is not enabled, the BPEL process waits until the Oracle BAM Server confirms that the record operation was completed; however, if there is a failure, the exception from Oracle BAM Server is logged and the BPEL process continues. BPEL does not roll back the operation or stop when there is an exception from Oracle BAM.
