Error Processing XML data from Queue

[vvsaucse]

$APT_DEFAULT_TRANSPORT_BLOCK_SIZE = 15242880
$APT_PHYSICAL_DATASET_BLOCK_SIZE = 10464640

The above are the Env variable values used. I am getting a similar error as previously posted. But changing the job now is not an option we have right now. Is there an alternative approach?

Below is the Error Message

wmqcInterFace,0: Fatal Error: File data set, file "/isdata/data/datasets/I006/ds_WMQMessagestmp.I006".; output of "wmqcInterFace": the record is too big to fit in a block; the length requested is: 11093136, the max block length is: 10465280.

Should i be increasing the Size of the Env variable.
I have seen a similar message posted on this portal previously but that was marked resolved.

Neither of these affect MQ.

Transport blocks are used when data are re-partitioned. Physical dataset block size refers to physical storage of Data Sets.
