As stated in the "What's New and Changed in IBM Data Studio Version 4.1" product documentation, features have been removed and are no longer supported in this release include "Support for collecting the actual values to compute the cost of SQL statements in DB2 for z/OS data sources". My concern about the removal of this feature is this:
1.) Will we see different estimates and if so based on what?
2.) Will the Explain generate different access paths as a result?
3.) How else are we going to get/compute the cost of SQL statements in DB2 for z/OS or DB2 for LUW data sources?
I will appreciate very much an and all verifiable answer to this question.
Thanks a million everyone!
