Currently our systems are developed and do run on NEX, MFE, and Mainframe platforms, so we are restricted somewhat in needing to keep code as compatible as possible. Out of 6000 modules, there are roughly 50 specific ones for each platform. At the moment we are using DB2LUW pre-compile and Bind functions delivered from IBM in the NEX platform. MFE uses the ECM and connects to XDB. The mainframe also uses the ECM and connects to DB2.  

-Would like to know when migrating to Enterprise Developer for Eclipse for both NEX and MFE platforms, what would you recommend? stay with the IBM tooling, migrate to OpenESQL or go with DB2 option?  

-Which method would be the most compatible considering we develop the same code base under MFE with XDB, NEX with DB2LUW and Mainframe DB2? 

-How do each of them compare in performance?

-Is there a list of pro's and con's  for each method?
