We are just rolling out 1.10 and one of my coworkers was running into a hang on 1 LPAR when using a "H ALL" in SDSF. I haven't "converted" that many people to using large screen sizes, but he is one of them. After I started debugging the problem by eliminating the VTAM session manager and the emulator we both were using (Vista TN3270), he opened a PMR. About 5 minutes later (after I had my coffee), I remembered your post and checked TSOKEY00 on this particular LPAR. On this particular LPAR HIBFREXT was set to 6600. It was set to 48000 everywhere else and we haven't seen a problem but we both use 62 x 142. Since ISPF does support larger sizes now, we changed this LPAR to 96000 and plan on changing the rest also. Glad I was monitoring IBM-MAIN on February 25th. :-) Mark -- Mark Zelden Sr. Software and Systems Architect - z/OS Team Lead Zurich North America / Farmers Insurance Group - ZFUS G-ITO mailto:[email protected] z/OS Systems Programming expert at http://expertanswercenter.techtarget.com/ Mark's MVS Utilities: http://home.flash.net/~mzelden/mvsutil.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
