I am new to the COBOL db2 field, so excuse me if the information is not sufficient.
We have 3 COBOL db2 programs which work just fine. Package bind and then plan bind works as usual and we do use changeman. Now my question is once a plan bind is complete, and then I update one of the 3 programs (updates are to the COBOL portion only. no change to the sql queries) changeman automatically does a package bind(which is fine and understandable). Now Is it necessary to do a plan bind again? And when I see the packages in the plan thru fileaid ca screen, I see the contoken is updated automatically in the plan for the particular package. Any help with how the plan gets updated with the new package information when a plan bind wasn't even done would be immensely appreciated.
