There are several 'mainstream' catalog management products that most likely could perform this function. I'm guessing that most shops already have or another of these products.
The (historic) problem with using native IDCAMS is the excruciating elapsed time to run thousands of DELETE/DEFINE or even ALTER commands. Unless that process has been highly streamlined since the last time we had to do this, what's needed is software that will in effect 'edit' the catalog rather than update it in the conventional way. Run time for us to invoke a third party utility was a fraction of what native IDCAMS would have required. . .

There are at least a couple of companies out there with catalog management products, I think. And a search of the CBT site might bear fruit. Many moons ago, after a similar search for existing tools, I wrote a quick throwaway program to parse LISTCAT output and build ALTER control statements for IDCAMS for exactly this purpose. (In our case, some people had used esoteric names to catalog their data sets using a utility or DYNALLOC--I forget which--and the catalog entries had to be fixed to move the data sets to different device types.) These days I'd think it more sensible to use the Catalog Search Interface to find the entries needed to build IDCAMS control statements, which would put a reasonably stable API on both ends of the code. There might be a better way but that's where I'd tend to start if I had to do it over today. (Well, actually, I'd start by dusting off the long-unused brain cells I once used for programming, but...) -- John Eells z/OS Technical Marketing IBM Poughkeepsie [email protected] ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
