Install DTrace on Oracle Linux 8

1. If running on an x86 platform, enable either the ol8_UEKR6 or ol8_UEKR7 yum repository for the system.

   For example, run:

   sudo dnf config-manager --enable ol8_UEKR7

   Note:

   Oracle releases UEK and DTrace packages in the baseos repository for aarch64 platforms. You don't need to enable any other repositories to access the DTrace packages for aarch64 platforms.

2. Install the dtrace package.

   sudo dnf install -y dtrace
