Send/Receive task vs Throw/Catch Message events in Oracle BPM

In Oracle BPM "Service task" is used for invoking Synchronous web-service calls. It wont be useful for Asynchronous service calls.

To deal with Asynchronous service calls, Send/Receive or Throw/Catch events need to be used.

There are few differences and similarities between Send/Receive and Throw/Catch Message events. Please have a look at them below.

	Send/Receive Task	Throw/Catch Message Events
Can it be used to initiate task?	Yes	Yes
Can it be used to call/invoke Synchronous services/processes?	No	No
Can it be used to call/invoke Asynchronous services/processes?	Yes	Yes
Does correlation/conversation need to be set to deal with Asynchronous tasks?	Yes	Yes
Can it have boundary events associated to it?	Yes	No
Can these pair be used to create synchronous process /service?	Yes	Yes
Can these pair be used to create Asynchronous process /service?	Yes	Yes

Send and Receive task example with boundary events attached to it can be found here.

How to control CUDA Devices to be used in Windows 10 for Keras/Theano/TensorFlow training

I've two 1080ti GPUs , I would like to use only one of the device for DeepLearning Training purpose,Most of the google suggestions advising to use CUDA_VISIBLE_DEVICES environment variable.Setting CUDA_VISIBLE_DEVICES either in windows environment variables are as programmatic way dint help much. But below approach helped to control the GPU usage for CUDA operations. Open NVIDIA Control Panel" by right clicking on the desktop screen. And select CUDA-GPUs to the desired gpu you want to use for DL training, In my case: I chose 2nd GPU Peace!!

Send and Receive Task example in Oracle BPM

This post talks about Oracle BPM process communication with Asynchronous service. When we talk about BPM process communication with other processes or services, Those processes or services can be synchronous or asynchronous. Synchronous process/service can be invoked with Service Call flow object in Oracle BPM. It will be a straight forward approach,just by adding WebService adapter at external references and using service task to invoke the service. In case of Asynchronous process /service,we must use send /receive task or throw/catch message events when designing flows in BPM. Summary : Asynchronous process wont wait for response to be returned immediately. As soon as its been invoked ,the process will be running in the background.Its the responsibility of calling process to make sure to look for callback response from asynchronous process for the sent request. In order to identify the correlation between request and response , the design has to be made in such a way to...
