Near Real time processing

[Former Member]

Hello All,

My Client wants Implement a Near Real time processing Interface. As part of this Interface, Information from related plant would be sent to SAP R/3 system from one of the Legacy system(file based). This is a File to Proxy scenario.

10.  Specify the following for the poll interval:  

○  Poll Interval (secs): Number of seconds that the adapter is to wait if no files are found for processing

○  Poll Interval (msecs): Number of milliseconds that the adapter is to wait if no files are found for processing

If you set Poll Interval (secs) to null, processing times will be short and close to real time.

If you set Poll Interval (secs) and Poll Interval (msecs) to null, the adapter is called once.

Here the SAP documentation mentioned above at this link http://help.sap.com/saphelp_nwpi71/helpdata/en/44/682bcd7f2a6d12e10000000a1553f6/content.htm

Keeping the above notes in mind, Can I set the Poll Interval to null in Sender NFS file adapter communication channel to make it close to real time? Is there are anything that needs to considered while setting the Polling Interval to Null? Is it impacts the PI server performance anyway?

Please guide me

Regards,

Moorthy

Hi Moorthy,

>>>>Can I set the Poll Interval to null in Sender NFS file adapter communication channel to make it close to real time?

yes ... you can. However, you do need to consider that will legacy be generating files this frequently. You can increase the poll interval to a positive number say 10 or 15 seconds or more as per the requirement.

>>>>Is there are anything that needs to considered while setting the Polling Interval to Null?

Nothing from a PI perspective.However you do need to consider the transaction being done through proxy in ECC to avoid any data locking issues.

>>>>Is it impacts the PI server performance anyway?

not a considerable impact.

Hope it helps!
