Identifying required patches for Linux is difficult because Linux is distributed as different levels, with different packages of an application on each. However, by setting requirements based on kernel and library levels, then evaluating each distribution based on this, a set of requirements can be determined.

By supporting specific distributions, a certain set of patches is guaranteed. At the lowest level, Linux kernel 2.2.5 or greater is required, along with glibc 2.1.1 or greater, and libstdc++ 2.9.0 or greater. Each of the supported/certified distributions contains these levels or higher. There is one exception to this rule: the version of glibc/libstdc++ installed must contain the libstdc++-libc6 naming convention. If it does not, you must make the appropriate link yourself (for example, on Red Hat 6.0, the file is /usr/lib/libstdc++-libc6.1-1.so.2. on Caldera 2.2, this naming convention is not used and therefore you must link /usr/lib/libstdc++-libc6.1-1.so.2 to the file /usr/lib/libstdc++.so.2.9.0 , which is the appropriate library). A distribution that meets these requirements should be able to accommodate the Domino server.

The upgrade from Red Hat 6.0 to Red Hat 6.1 contains patches to the Linux kernel which allow larger process/thread limits and increased file descriptor limits.

Beginning with Release 5.0.9, the Domino server is supported on Red Hat 7.1 and higher, and SuSE 7.2 and higher. For Redhat 7.1 and 7.2, you must apply the glibc and gdb errata/bugfixes for these levels which should bring glibc to 2.2.4-19 and gdb to 5.0.1 or higher.

See the "Linux settings" topic in these Release Notes for additional important information about the Linux system you choose to run beneath the Domino server.
