java.lang.OutOfMemoryError

[Former Member]

Hello, I have created a mapping of a XML document to an IDOC and the procedure to do that was:

First I use a jco to check if a vendor exist, later I map the incoming xml message to an Idoc. To create the Idoc I have filled all the SEGMENT with 1 and an empty value for the others fields that does not have a corresponding value from my XML input file, I did in that way because the system could not compile the mapping if a field in the target XML (IDOC) was not mapped. I can compile the mapping in the design tool but when I choose to test my mapping nothing happens??

In runtime the mapping give me an out of memory error

What I can see from the error is that the document is to big for XI, do I need to change a parameter somewhere in XI. Does anybody know what maybe my problem.

Hi!

Make sure that you do not have the parameter -Xnoclassgc in j2ee/cluster/server/cmdline.properties (see SAP Note 718747) which prevents garbage collection. When we removed the parameter we did not have any out of memory situations while executing mappings any more.

Hi there,

There is a very good tuning document on the SDN. Just type "XI Tuning" in the search field and it should be the first document that appears. Try some of these settings, maybe it will help.

Good luck.
