First, his library is PDS/E, so visible blksize may not reflect actual. It does appear to be full.
On the other points, I definitely agree with the suggestion for more pts libraries and DDDEFs vs. DD statements. My ZOS 1.11 pts is 300,000 tracks of PDS/E on 6 volumes (mod3) Dave Gibney Information Technology Services Washington State University > -----Original Message----- > From: IBM Mainframe Discussion List [mailto:IBM-MAIN@bama.ua.edu] On > Behalf Of Schwarz, Barry A > Sent: Thursday, April 28, 2011 12:03 PM > To: IBM-MAIN@bama.ua.edu > Subject: Re: SMPPTS run out of Space > > The 32720 blocksize is not very efficient for a PTS library.
