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?

Re: PDSMAN Replacement
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:ibm-m...@bama.ua.edu] On Behalf Of Mark Wilson Sent: Thursday, May 21, 2009 1:30 AM To: IBM-MAIN@bama.ua.edu Subject: PDSMAN Replacement Hi, I have the task of removing CA-PDSMAN from two of our systems.

Since the OP said he would convert to PDSE, he can take advantage PDSE / SMS caching (so make sure the PDSE is SMS controlled). Be sure to review technote TIPS0567 - Partitioned Data Set Extended (PDSE) Hiperspace (Caching) Problems, Considerations, and Parameter Changes which explains the caveats including CPU cycles (I have no idea how much PDSMAN Dynamic BLDL Facility costs in terms of cycles and storage). In addition the OP should make sure to use the IGDSMSxx parm / setting: PDSE1_BUFFER_BEYOND_CLOSE(YES) PDSE_BUFFER_BEYOND_CLOSE(YES) isn't really helpful since the LNKLST is never closed anyway. (note the difference between PDSE1_ PDSE_) The Partitioned Data Set Extended Usage Guide Redbook is a good source also (SG24-6106). If you search the Redbook site you should be able to find both of the above. The remote Data Compare is used in batch to compare PDS¹s on the QA Production systems.

Nothing slick. Perhaps if you can get a shared volume between the 2 environments you can run a job that copies one of the 2 libraries you are comparing in the first step to the shared volume and then submits a job (NJE, FTP) to run on the other system that uses IEBCOMPR. The 2nd step of the submitted job could use any standard opswto program to generate the WTO / WTOR based on a non-zero return code.

Re: PDSMAN Replacement
Mark - Something you should take into consideration about going the LLA-route with your large load library is how often the library is updated. Putting the library in LLA Freeze mode brings you directory search performance benefits, but can lead to problems when members are updated. This is the Dynamic part of the Dynamic BLDL facility. On the other hand, if you use LLA NoFreeze mode you lose much of the performance benefit you seek. Is there a particular reason you're being asked to remove PDSMAN?
