I have a ThinkPad T430 with 8 GB RAM and an Intel Core i5 3320M running Red Hat Enterprise Linux 6.7 using kernel 2.6.32-642, and a KVM-QEMU VM running Debian Jessie for AMD64 with kernel 3.16.0-4, and I am trying to install IBM DB2 Advanced Enterprise Server Edition 11.1 (as an IBM employee I can use it without cost for private purposes, training in my case) using X forwarding for graphical interface (which I know it works because from the same command prompt I can launch Synaptic). When I try to launch the official db2setup graphical installer I get the splash screen, but then the installer quits.
Reading the installer log file /tmp/db2setup.err, the crash is due to a segmentation fault on library libdb2ure.so, which is supplied by IBM on the installer package. Googling revealed two possible fixes that didn't work: adding my machine's hostname to /etc/hosts (did that to no effect), and making sure to install DB2 from a local filesystem (I am doing that). Then I followed this post and tried making sure all the library's dependencies listed by readelf were installed (they are), then I installed the Korn shell (KSH93) from APT (it didn't work).
I would like to explore other possible fixes before going ahead with building another VM running CentOS (DB2 is certified to run on RHEL, not Debian), as I fear running a second VM for my DB2 server would put too much strain on my workstations's RAM.
