Java.lang.OutOfMemoryError during transfer of large data from SAP to PI

Question

Hi experts,
We are trying to transfer large data from SAP to external system via PI but the transfer stucked in sm58 of SAP system with 'error java.lang.OutOfMemoryError'. We have tested before this and we can only get approximately 100K of records to go through successfully. We neeed approximately transfer 300k datas per time. Current setting of max heap size (in mb) of our PI system is 512 at message server and bootstap tab. At servers general tab the max heap size (in mb) is 2048 and its java parameters are having the values below:
-Xmx1024m
-Xms1024m
-Djco.jarm=1
-XX:PermSize=512m
-XX:MaxPermSize=512m
-XX:NewSize=320m
-XX:MaxNewSize=320m
What need to be increased to solve the error?
Thanks.

Hi Thava,
We can set a limit on the request body message length that can be accepted by the HTTP Provider Service on the Java dispatcher. The system controls this limit by inspecting the Content-Length header of the request or monitoring the chunked request body (in case chunked encoding is applied to the message). If the value of the Content-Length header exceeds the maximum request body length, then the HTTP Provider Service will reject the request with a 413 u201CRequest Entity Too Largeu201D error response. You can limit the length of the request body using the tting MaxRequestContentLength property of the HTTP Provider Service running on the Java dispatcher. By default, the maximum permitted value is 131072 KB (or 128MB).You can configure the MaxRequestContentLength property using the Visual Administrator tool. Proceed as follows:
       1.      Go to the Properties tab of the HTTP Provider Service running on the dispatcher.
       2.      Choose MaxRequestContentLength property and enter a value in the Value field. The length is specified in KB.
       3.      Choose Update to add it to the list of properties.
       4.      To apply these changes, choose  (Save Properties).
The value of the parameter MaxRequestContentLength has to be set to a high value.
In short parameters to reset values for ABAP side are
icm/HTTP/max_request_size_KB
icm/server_port_ TIMEOUT
rdisp/max_wprun_time
zttp/max_memreq_MB
Parameter to reset values for JAVA side is MaxRequestContentLength.
You can use following link to know more about ICM parameters
