The inserted data into the BPEL_MESSAGE and BPEL_XML_DATA tables may sometimes be larger than the columns can hold so during insert I get an SQLDataException: DB2 SQL Error: SQLCODE=-302, SQLSTATE=22001, SQLERRMC=null, DRIVER=4.11.77.
An example when the data may/are larger is when the massage payload is to large or the message includes authentication data.
