Probably you did not add classification rules for your distributed DB2 transactions to your WLM service definition. Unclassified distributed DB2 transactions are assigned to the ‘SYSOTHER’ service class which has a discretionary goal. Using the WLM application, you need to add a set of classification rules under the ‘DDF’ subsystem type and assign the distributed transactions to service classes with appropriate response time or velocity goals.
