You may have some problems with that processing. Just to make sure you're aware of some of them: (a) Step 3 might fail (I think) for SMS-managed data sets, as they can't be uncataloged. (b) For non-SMS-managed data sets, step 3 will succeed if you have either ALTER authority to the data set via your security product, or ALTER authority to the catalog. However, step 5 will only succeed if you have ALTER authority to the data set, or at least READ authority to the DASDVOL profile protecting the volume the data set is on. The net of this is that you might successfully uncatalog the data set, but fail to scratch it. (c) You may also need to do something different for migrated data sets (volser of MIGRAT, I think). -- Walt Farrell IBM STSM, z/OS Security Design ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
