I just finished an install of the 64-bit Sybase ASE server on Fedora 6. I had to do a few things to get this to work that others might run into.
0. For some reason the Sybase setup utility refuses to run regardless of X11 security. I ran "setup -console" for a text version of the install (why everyone seems to think everything has to be GUI is beyond me anyway).
1. Sybase (64-bit) requires a libaio package that wasn't installed by my Fedora install. It would tell me that libaio.so.1 can't be loaded when trying to start the server. I managed to get this library using the Fedora add/update software GUI tool. This tool is a pain. The best bet is to use "list" and just find it. The package providing this library has an obvious name.
2. The server still won't start. A look at my server log in the Sybase software target directory, and down in "install", said it was unable to allocate the needed amount of shared memory. To correct this, I added this line:
to the file /etc/sysctl.conf and then ran the command "/sbin/sysctl -p". Then I went over to the Sybase install directories and started the server as I normally would. It worked.
3. The Sybase environment variables are setup in the install directory in some sample scripts. On my machine, that's /opt/sybase/SYBASE.sh for example.
A note about the Fedora software update program - it is truly shockingly awful. For one thing you can not use it if you are not connected to the internet. It will not install software from CDs or a DVD without some modification for which no help is provided (do some searches on Google to get some tips if you have to do this).
Also, Sybase does require a few other packages. But if you installed Fedora with various development options, you'll get them. It also needs a Java install.
It is said that the 32-bit version on ASE can run on a 64-bit Fedora install too, but to do that you must collect up some 32-bit libraries by, get this, installing the 32-bit version of Fedora someplace and copying off the needed files. Here's a tip on this:deeply flawed with regard to hardware identification, particularly for graphics systems. There's no excuse. Other distributions are vastly superior in this area.
