Fapolicyd software framework (Linux)

For Db2 to install and run commands successfully on RHEL 8 and newer versions, fapolicyd software framework cannot be active.

On Red Hat Enterprise Linux (RHEL) 8 and newer versions, the fapolicyd software framework controls the execution of applications based on a user-defined policy. In its default configuration, fapolicyd can block the installation of Db2 and most Db2 commands from running. For this reason, Db2 does not support an environment where fapolicyd is active.

You can check the status of fapolicyd with the command:

systemctl status fapolicyd

To turn off fapolicyd, run the command:

systemctl stop fapolicyd

If fapolicyd is enabled, some common error messages can appear when you try to install Db2, such as:

error while loading shared libraries: libdb2ure.so.1: cannot open shared object file: No such file or directory

db2start: Operation not permitted
