The Apply Engine has the ability to communicate with other Apply Engine instances through TCP/IP across different operating systems, within the same operating system instance or both.
Connect CDC (SQData) TCP/IP cross platform operation through is defined through the DATASTORE command. Examples of how to specify cross platform operation within the DATASTORE command are provided later in this section.
In a cross platform TCP/IP environment, an Apply Engine can function as a sender of information or as a receiver of information, or both. There may be multiple Apply Engine senders/receivers communicating with each other in a cross platform environment. An Engine subscribing to an IMS Log Capture, formats a record which is then written to a TCP/IP port on another platform on which a second Engines is listening. While an Engine can Listen and Write to a TCP/IP port most do not.
- Port - This is a TCP/IP communication port that is used as the data transfer conduit within and between operating system platforms.
- Sender - This is an instance of the Apply Engine that is setup/defined to send data to a TCP/IP port.
- Receiver - This is an instance of the Apply Engine that is setup/defined to receive data from a TCP/IP port.
