Error with JMS adapter

Question

We are using a JMS adapter with XML input files and we are getting the following error:
:#1.#00144F80C55600310000001A00001BC700DD9B18A4E85181#1288983973313#com.sap.engine.messaging.impl.core.queue.consumer.SendConsumer##com.sap.engine.messaging.impl.core.queue.consumer.SendConsumer.handleRetriesOnException(MessagingException, QueueMessage, MessageController)#J2EE_GUEST#223963##<applicationserver_hostname>_<SID>_623765##8bfba530dea111dfbf9b00144f80c556#MS Queue Worker [JMS_http://sap.com/xi/XI/SystemSend]##0#0#Error##Java###Transmitting the message to endpoint using connection failed, due to: .#3#JMS_http://sap.com/xi/XI/System#com.sap.engine.interfaces.messaging.api.exception.MessagingException: Error transmitting the message over HTTP. Reason: java.io.IOException: Error writing to server#http://<hostname>:50000/sap/xi/engine?type=entry#
One that is interesting is that these errors are occurring on application servers only.  Could it be that the Integration Server URL is not fully qualified.  In the SLD it's just <hostname>, not <hostname>.test.com (as an example).
Any help is greatly appreciated.

Answer 1

Dear George,
Concerning the issue, in the Integration Engine please try increasing the value of the parameter :
   - icm/HTTP/max_request_size_KB
from the default size of 100MB to e.g., 2GB.
Kindly go through the following link :
- http://help.sap.com/saphelp_nwpi71/helpdata/en/58/108b02102344069e4a31758bc2c810/frameset.htm
for details.
Additionally, it is recommended to setup a large message queue,
i.e.,
add an entry and appropriate value (e.g., 20480 KB) for the TUNING parameter : 'EO_MSG_SIZE_LIMIT'
using
TCODE
   sxmb_adm
    Integration Engine Configuration
      Select Edit mode and Add the TUNING parameter
I Hope this helps.
Best Regards
