Typical upgrade of Oracle-supported RDMA package can be achieved using the dnf update or yum update command. Note that the yum commands used in this procedure are interchangeable with the dnf command available in Oracle Linux 8.

If you're upgrading a system where the oracle-rdma-release or oracle-rdma-release-guest package is installed and the package version is lower than version 0.18.1-1 and you intend to upgrade to version 0.18.1-1 or above, you must first manually remove the rdma-core-devel package before performing the upgrade. Remove this package using the rpm -e --nodeps command to remove the package outside of the standard yum or dnf package manager control and leaving any dependencies intact, for example:

sudo /bin/rpm -e --nodeps rdma-core-devel
sudo yum update

If you're upgrading an older system where the oracle-ofed-release or oracle-ofed-release-guest package is installed and you intend to upgrade to oracle-rdma-release or oracle-rdma-release-guest version 0.18.1-1 or above, you must manually remove development packages that were installed for OFED before performing the upgrade or installation of the oracle-rdma-release or oracle-rdma-release-guest package:

sudo /bin/rpm -e --nodeps libibumad-devel libibverbs-devel librdmacm-devel libibmad-devel
sudo yum install oracle-rdma-release-guest

Note that these steps are only required for the transition from versions of the oracle-rdma-release and oracle-rdma-release-guest packages prior to 0.18.1-1 to version 0.18.1-1 or later; or for the transition from oracle-ofed-release to oracle-rdma-release version 0.18.1-1 or later. These steps aren't required for upgrades after the packages are at version 0.18.1-1 or later.

sudo yum remove oracle-rdma-release*
