I once worked in a shop with one production load library. It was a mega headache posing performance, security, and RAS problems. We took frequent unplanned outages while the library was compressed. And that was a tiny shop over 40 years ago.
I am a little surprised that your auditors have not kicked your backside over this long ago. Anyway, I'd begin a conversion to application level load (and source) libraries ASAP. Be prepared to deal with debris that no one is going to know anything about. As to the compare requirement, I'd look at the native TSO PDS compare utilities. These are pretty easy to set up in batch and there should be return codes or some such usable to trigger your automation. -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Mark Wilson Sent: Thursday, May 21, 2009 1:30 AM To: [email protected] Subject: PDSMAN Replacement Hi, I have the task of removing CA-PDSMAN from two of our systems. We currently use the following functions: * PDSMAN Library Space Reuse facility * Dynamic BLDL Facility * Remote Data Compare I believe I can convert my PDS¹s to PDS/e¹s to negate the need for the Space Reuse facility. The Dynamic BLDL function causes me a little concern. I have inherited a situation where we have one massive load library that contains all batch & online application programs. All batch jobs and online systems have either a JOBLIB or STEPLIB DD Statement that references this one library. Many years ago (well before my time) the techies turned off this PDSMAN feature and had very severe system performance issues for online and batch applications, resulting in this feature being re-enabled. I was think of splitting the library, perhaps by application to reduce the search time for none application code. The remote Data Compare is used in batch to compare PDS¹s on the QA & Production systems. A checksum is generated for each PDS and then compared. If a difference is found a WTO is posted (picked up by automation) that triggers a check of the libraries. Does anyone have any experience of replacing these functions and have any ideas of how to replace and any advice on the process?
