You can increase the heap with the following command:
| Code: |
| mqsichangeproperties brokerName -e executionGroupLabel -o ComIbmJVMManager -n jvmMaxHeapSize -v newSize |

You probably need to set the heap to be larger than it was by roughly twice to three times as large as the size of your biggest file.
So if you are going to read a 1GB file, and your heap was 1GB, you should increase it to 3 to 4 GB.

Hi,
Can you please post the errors you are getting? The FileRead node logs its errors in Documents and Settings\All Users\Application Data\IBM\MBFE\log directory.

Hi,
Can you send me an e-mail with the messageflow project export (as a zip file) along with the sample message.

nmaddisetti,
Did you resolve this or did you raise a problem with IBM support ?
