Issue/Introduction

Upgrading from Gen release 8.5 to release 8.6, using 3270 block mode COBOL applications:  Will the models have to be regenerated?

Environment

Release: 8.5 to 8.6

Resolution

Most re-generation of models is not necessary as the schema does remain the same at 9.2.A6. Therefore it is not required to regenerate or recompile applications/models (one exception is noted below for CICS). As long as the applications are running without problems under release 8.5, then they should continue to do so under release 8.6 with all of the maintenance applied. The 8.6 runtimes will need to be inserted any user exits modified in 8.5 will need the same changes in the 8.6 versions.

Please note: CICS applications built using Gen 8.5 before 8.5 PTF RO86229 was applied will need to be regenerated and reinstalled. Server-to-Server applications built before Gen 8.5 PTFs RO83361,RO84681, RO84682 and RO84683 were applied will also need to be regenerated and reinstalled. The best way to currently identify is with an AMBLIST of the Executable modules/DLLs (including Gen Runtimes) and compare that to an SMP/E report of the PTFs applied.
