Polling by file adapter (sender) with FIFO functionality

[frank_schmitt3]

Hi,

here are one question:

What happen if, for example, the sender system generates multiple files with the same timestamp (HH:MM:SS), or the file adapter on XI is stopped for a moment, and then, when activated, in the source directory (polling directory) there are many files? How can XI handle the correct sequence of messages? Is this impossible. How XI poll on a file (sender) - what is the logic? The files should be polled by FIFO.

Thanks in advance.

Hey

If you have given transport protocol as NFS then files are either processed in alphabetical order(if processing sequence is "by Name") or by Last modification timestamp(if processing sequence is "by Date").

If transport protocol is FTP then files are always processed in alphabetical order

for more information check question 12 of SAP Note 821267

Thanx

Hi,

Suppose your Quality Of Service is exactly once in Order (EOIO), then It takes care of this type issues.

Some times we gives priority to the Queues also based on that priority it can execute.

You can use EOIO in QOS parameter with queue name provided

EOIO:

Messages are delivered with the same queue names in the same sequence that they were sent from the sender system. Message processing is asynchronous in this case

EOIO does not process files in the order of time stamp used in file name. What ever file is picked by the sender adapter first is delivered first. But it can not pick the files based on time stamp.

Hi,

There is a logic called EOIO. Its exactly once in Order (EOIO). It takes care of all these iisues. Also XI gurantees the delivery of files.
