****************************************************************************** 1) IBM R/6000 users wishing to upgrade to OS 3.1.7 should know that there are problems with UUCP: > Are you running 3.1.7 of the OS, or 3.1.5? What is the nature of problems > with UUCP? > > Thanks, > Tasos > 3.1.7 is the version I'm on under the AIX. When I refer to 2007, it breaks down as : 2 - Update to most current previous version 00 - ??? 7 - New version number. When you refer to a 3005 tape, it means 3 - Replacement for a previous version, totally. 00 - ??? 5 - New version number. So, when I went from 3.1.0 to 3.1.5, I got a 3005 tape. When I went from 3.1.5 to 3.1.6 I got a 2006 tape, and from 3.1.6 to 3.1.7 I got a 2007 tape. When they come out with 3.2, it'll probably be a 2010 tape. Also, you can not go from 3.1.5 to 3.1.7 with a 2007 tape, you MUST be on the x-1 gen (3.1.6). The problems are that it does not spawn the polling processes in /usr/spool/cron/crontabs/uucp. ****************************************************************************** 2) Systems running under AIX 3.1.7 have yet another problem with cron. This can be fixed by APAR #a21036 ****************************************************************************** 3) "BTW: PLEASE inform whoever runs the AIX that you use to do debug work there that he MAY have gotten SCSI update code on disk recently, and NOT to install it! There is a good chance his system won't come back up." ****************************************************************************** 4) Problems migrating from SUN OS 4.1.1 to SUN OS 4.1.2: Got it. The problem is on SunOs 4.1.2. I had rebuilt libc.so so the machine could be a resolver w/out needing to run DNS and only needing resolv.conf and a route to the gateway. Anyway, If one does this (or a few other things as well) ld gets sick like I described before. The answer is to get a jumbo patch from Sun support. The patch reference is: 100532 (International) or 100531 (Security). It also corrects the Makefile in /usr/lib/shlib.etc by putting a -ldl switch on ld. This switch can probably be used in other makes as a possible workaround. I'll try it tomorrow. ****************************************************************************** 5) Article 15006 (36 more) in comp.unix.aix: From: lubkt@synergy.CC.Lehigh.EDU (Binod Taterway) Subject: C routine realloc() seems broken in AIX 3.2.2... Message-ID: Date: 17 Aug 92 16:37:28 GMT Sender: usenet@chili.cc.lehigh.edu Distribution: comp.unix.aix Organization: Lehigh University, Bethlehem, PA Lines: 16 Nntp-Posting-Host: synergy.cc.lehigh.edu FYI - AIX 3.2.2 has broken all my realloc() calls. The code that worked on AIX 3.1.8 (and all previous releases) now gives core dump after I upgraded AIX. I get - Catastrophe in realloc: invalid storage ptr IOT/Abort trap(coredump) ****************************************************************************** 6) malloc() under 3.2 may cause bur errors: From the malloc man page: Note: AIX Version 3.2 allocates memory using a different method than in previous releases. Some applications may fail due to this new method. Therefore, AIX Version 3.2 supports both the old and new memory management strategies. The MALLOCTYPE environment variable can be set to access the older version. To use the old memory allocation method instead of the new, enter: MALLOCTYPE=3.1; export MALLOCTYPE setenv MALLOCTYPE 3.1
