    Hi Renu,

    There is no particular figure from SAP, it depends on your server configuration.

    PI will give best performance if you process 5mb messages.

    Hi Renu,

    This depends upon your hardware and sizing of the XI box. so it also depends on how complex your mapping and whether you are using any BPM inside the scenario or not. I have come across where XI is used just to move the file of 1GB also.

    but this is thro various tech like message splitting by using BPM.

    so if you r sending the file of large size it surely brings XI down so it is adviseable to read chunks of data into XI and process further.

    for message splitting you can use below links

    Hi,

    Actually it depends on a number of factors:

    1. The size of the Java heap, which is shared among all messages processed at a certain point in time. In order to be able to process larger messages without an out of memory error (OOM), it is recommended to increase the size of the available Java heap and/or to reduce the concurrency in the system so that fewer messages are processed in parallel.

    2. Using the transport protocol "File Transfer Protocol (FTP)" also uses more memory for processing than the transport protocol "File System (NFS)" (up to and including XI 3.0 SP 13).

    3. If the Message Protocol "File Content Conversion" is used in a File Sender channel, consider that not only the size of the input file affects the File Adapter's memory usage, but even more the size of the XML resulting from the conversion, which is usually a few factors larger than the original plain text file.

    To reduce the memory consumption, set "Maximum Recordsets per Message" for the sender channel. This will cause the input file to be split into multiple smaller mesages.

    But to be on safer side few megabytes are ok i guess.

    Regards,

    Shradha

      Hi,

      If your hardware configuration is okay then it can process 2 GB files without any problem...

      I use to process 1.5 GB files daily thru my PI interface.

      Thanks
