While playing with PI 7.1 EHP1 I found an interesting feature that can easily support file-to-file transfer scenario especially dealing with big file size. The feature is only available for file-to-file scenario using EOIO quality of service. The feature is named ChunkMode and it enables splitting binary sender files into fixed “chunks” in order to process big file without affecting J2EE engine of PI system.
Even if this feature seems to be not yet mentioned into SAP NetWeaver PI 7.1 EHP1 documentation page, the screenshot below shows the additional attributes of Adapter Metadata File into PI 7.1 EHP1 not present into PI 7.1 version one.
To enable ChunkMode, at first, set the Quality of Service to Exactly Once In Order with a specified queue name for the sender communication channel then set the advanced mode of the channel and define the Maximum Size[MB] for the chunks. As receiver communication channel no relevant options must be configured.
For testing the solution just create an Integrated Configuration object to define a scenario using sender and receiver communication channel before mentioned. In the test I did, some files were placed inside one ftp server and then processed successfully using EOIO with chosen queue name as shown in the pictures.
Finally I did some tests tuning chunk size of sender communication channel, and that is the summary of processing time for the qualitative test done.
