Has anyone here done the jump from z/OS 1.7 to z/OS 1.11 without going throu= gh 1.9 first? If so, can you tell me any specific "gotchas" that you came a= cross? <SNIPPAGE> This just came up on CICS-L in a matter of speaking. CSA KEY8 GETMAIN will probably fail. You will need to make sure that you either have all software using CSA upgraded, or you will need to set the system to allow it. Storage Management Change Storage may be allocated differently (depending on PARMLIB settings). With the new method, Storage now is gotten at the bottom of a page (rather than top) and moves up (which prevents some fragmentation of storage). This means that a GETMAIN may have part of the storage in an existing page with the rest in a subsequent page. So your storage won't be "properly" initialized. There is an option to cause z/OS to use the old storage management rather than the new storage management. Those are just two items to watch for.
