Web Service Message Size Limit?

[Former Member]

Greeting All,

MII: 12.0.3 -- Trying to pass a 4.8MB XML message through a web service to another system. Getting a Status (500): Internal Server Error message

Any thoughts? Is there a limit on max message size in a web service call?

Alin,

The only limit is JVM memory on the system which for v11.5 unfortunately is limited to a max of 1.5GBs since only one instance of the JVM can be used. In newer releases of MII that run on NetWeaver multiple JVM instances can be created on the same machine and utilize more of the system memory.

With that said is it just the WS call that fails (Try calling an empty transaction) or a specific action in the transaction that's blowing up? Also increase the Web Service Request Timeout duration to avoid communication timeout. It would help to know so we can properly address it.

Alin,

I ran into similar issues and am not sure whether the limit is documented anywhere but you can try looking into the SAP note 723909 and make sure that you have correct set of JVM parameters for your system.

Heap size, perm size, new size along with the host of other parameters should be set as per your system hardware.

Thanks
