XI getting slow after process very large message.

Hi All,

I had load data more than 50 MB after that I cannot access any function from browser(RWB,message monitoring,..) but in ABAP side that still work fine. I guess that j2ee engine still process the message that is a reason. So how I can stop the process when I load the the large files. I already try delete queue,delete workitem from SWWL,cancel the message. But nothing happen XI still very slow.

Do I have to only start/stop J2EE engine?

Could you please to advice?

Thanks

Park

    Hi Park,

    -->So how I can stop the process when I load the the large files.

    Have you tried to stop/restart the particular adapter service by which you are sending the data to IS.

    -->I already try delete queue,delete workitem from SWWL,cancel the message. But nothing happen XI still very slow.

    Do I have to only start/stop J2EE engine?

    Seems so..

    Just wanted to know :

    Are you talking about production server..?

    Which type of data you are processing..?

    Which type of adapter you are using for this purpose..?

    Regards,

    If the "browser" functions are not working it is possible that the java part of the XI just crashed and you have to restart the J2EE engine.

    50 Mb is a very large message and can be very close to the upper limit XI can process. I advise you not to create such huge messages.

    HI Park Saeiam ,

    in adition to Marcos

    If the "browser" functions are not working it is possible that the java part of the XI just crashed and you have to restart the J2EE engine. your message may show error HTTP STATUS CODE 401 authorization error

    this error generally occurs when java part of the XI crashes and server is unable to recognise your browser and your credentials.

    In that case you need to restart J2EE engine and also you need to manually restart all asynchronous messages which will come in error due to restarting of J2EE engine.

    I advise you not to create such huge messages.

    also you may try to send this kind of huge message through IDOC package

    IDocs are normally sent in packages between systems. You configure this within the IDoc configura-tion partner profile by specifying processing mode Collect IDocs and transfer. IDocs are then proc-essed by report RSEOUT00 in the sender system. During inbound processing in the IDoc adapter of the Integration Server, this IDoc package is split up into single XI messages. Therefore, an IDoc pack-age cannot be processed as one unit within XI. This also has an impact on performance.

    In SP11, a solution will be available for IDoc adapter outbound processing to collect IDoc-XML mes-sages and transfer them as an IDoc package, as in the traditional IDoc world.

    The IDoc adapter is designed to be able to process IDoc-XML structures that represent IDoc pack-ages.

    Hi,

    Try to check if you can increase the Java Heap size to help processing large message size. You may need to process the files in chunks since the message size mulitiples by approx 5 times in Async processing and the XML message size may be larger than the Flat File size after Content conversion. If BPM is used then these message size will be mulitpled by a large factor depending on the Process performed.
