The issue with simple unload is that there is limitation on size of query - when using DSNTIAUL. Although the source code is available for DSNTIAUL, on talking with DBAs, it would be next to impossible to change the code. also tried to create a view and do view unload. That is impacting CPU time a lot. The query is very complex - queries 20-30 db2 tables in 1 query and uses TABLE , case when clause etc. with DSNTEP2 the query runs in less than 10 min and uses very less CPU. Hence the need for post processor module that does formatting of the file..
