The tests of the base + system gives equal results than on Solaris. There are + some problems with the 'ic' application (CORBA) and there + may be some 'mnesia' problems (the tests where not completed + when I wrote this note) + + * OTP normally try to handle IP host name lookups + by itself, parsing /etc/hosts and other configuration + files. This is done because the normal calls like + gethostbyname() is blocking. In this UnixWare port + the normal gethostbyname() is used and if a reply + from the name server takes some time this may block + the OTP system from doing other tasks (it may be the + case that it doesn't block the whole system, it may + just keep other Erlang processes that do DNS lookups + waiting, I'm not sure). + + * The erl_interface library support varios types of threading + This is not supported in the OTP UnixWare release. + + * If you use gcc you compile and link dynamic drivers with + + gcc -fPIC -c foo.c + ld -G -t text -o foo.so foo.o + + With the UnixWare C compiler I belive it will be + + gcc -KPIC -c foo.c + ld -G -t text -o foo.so foo.o + + * The default shell limits was a problem when I was running + some large tests. These limits can be changed by building + a new kernel. To enable unlimited use of virtual memory + and data you do as root + + % /etc/conf/bin/idtune SDATLIM 0x7FFFFFFF + % /etc/conf/bin/idtune HDATLIM 0x7FFFFFFF + % /etc/conf/bin/idtune SVMMLIM 0x7FFFFFFF + % /etc/conf/bin/idtune HVMMLIM 0x7FFFFFFF + % /etc/conf/bin/idbuild + + When you reboot a new kernel will be built. + + * I didn't give the system enough swap space. You can add + swap on an ordinary file. To add about 100 MB more swap + you do as root + + % dd < /dev/zero > /moreswap bs=512 count=200000 + % swap -a /moreswap 0 200000 + + The first line will create a 100 MB file on the root partition + and the second line will add this file as swap space. Note that + the "swap" command is a bit buggy and may hang. Reboot UnixWare + and try again. + +Internel notes on build the release + + * If the network addresses are changed you enter single user + mode by hitting a key after the "Booting UnixWare..." and + the beep. At the prompt + + BOOT# Hit return only to clear line + BOOT# INITSTATE=S + BOOT# go + + This will put you into single user mode. Find out ip address, + default router and DNS server.
