Description:
In Tibco product download site, we have the following package for TIBCO Enterprise Message Service on Linux:
  
"Red Hat Enterprise Linux 4 (x86), Oracle Enterprise Linux 4 (x86) and Novell SUSE Linux Enterprise 10 (x86) TIB_ems_5.0.0_linux24gl23_x86.tar.gz  77197 (Kb)  "
  
Here we only list several popular Linux versions. However, we support EMS on Linux platforms based on the Linux kernel version and glibc version.
For EMS 5.0.0, we support Linux kernel 2.4 or 2.6 and above and glibc 2.3 and above.
Therefore we support EMS 5.0 on Novell SUSE Linux Enterprise 9 (x86) and Red Hat Enterprise Linux 5 (x86) also.

If you do not know if EMS 5.0 is supported on your box, you could verify the kernel version and glibc version on your box by:

-- run "uname -a" to get kernel version
-- run "rpm -q glibc" to get glibc version
