Peter, In reality it is just "time". Converting the libraries from PDS to PDSE can proceduralized to some extent. Probably north of 90% of the libraries can be hit an an appropriate time, and the remaining hard to get ones will take some special actions to get them when they are free. One of the biggies for us is not just the conversion, but how much space to add to the datasets to accommodate over time the larger load module sizes for the debug information.
Additional heartburn for us is all the new AMODE/RMODE restrictions that is going to force quite a bit of analysis and research. We won't do a "recompile everything" approach, that is too high risk. And I am sure we have some amount of the stuff that incompatible according to the migration guide. _________________________________________________________________ Dave Jousma Assistant Vice President, Mainframe Engineering [email protected] 1830 East Paris, Grand Rapids, MI 49546 MD RSCB2H p 616.653.8429 f 616.653.2717 -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Farley, Peter x23353 Sent: Tuesday, September 24, 2013 8:47 AM To: [email protected] Subject: Re: PDS/E, Shared Dasd, and COBOL V5 Tom, to use the process you describe there are literally hundreds of thousands of JCL's to be changed, and tens of thousands of PROC's, and that is just one large shop. The only "zones" are QA and Production, shared by all applications. Where do you start such a project? The cost of regression testing alone is huge, especially in already CPU-constrained testing environments. New business lines, new regulatory issues, new clients: All these will take precedence over any kind of maintenance project, whatever the eventual ROI might be. Programmers like me would desperately love to see the new compiler in action and get going on using the enhanced facilities -- but the procedural hurdles that IBM has thrown up with this PDSE requirement are going to be staggeringly expensive to cross over. Will-we-nil-we, I suppose we will eventually get there, but it's not going to be quick or easy, and far, far from cheap.
