MCATYPE attribute value:
* SAME - Attribute remains unchanged
* PROCESS - MCA runs as a separate process
* THREAD - MCA runs as a seperate thread

The sender, receiver and server channel uses PROCESS. The cluster sender and receiver channel uses THREAD.

Advantage of running as a PROCESS

According to the intercommunication manual starting a thread is much faster than to instruct an OS to start a process. Apart from that thread can be easily configured from the command line. Also thread uses less storage space.

Advantage of running as a THREAD

Accord to the intercommunication manual:
v Isolation for each channel providing greater integrity
v Job authority specific for each channel
v Control over job scheduling

My understanding what the intercommunication manual is saying stated below:

As for process the channel is isolated to provide greater integrity. Since a process runs independently from each other therefore it is treated as a seperate entity. So once the process runs independently it will have sufficient privilage and priority over completing task.

Can anyone kindly help me to understand what the intercommunication manual is saying?.
