usu oracle optimization DOWNGRADE

Affected: 5.16.2

Fixed in: no fixed release known

Safe to downgrade to: a release before 5.16.2

1. Check installed version

apt-cache policy oracle-optimization || rpm -q oracle-optimization || oracle-optimization --version

2. No fixed release: DOWNGRADE to a release before 5.16.2 (Debian / Ubuntu)

apt-cache madison oracle-optimization sudo apt install oracle-optimization=<VERSION_BEFORE_5.16.2> sudo apt-mark hold oracle-optimization

2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list oracle-optimization sudo dnf downgrade oracle-optimization-<VERSION_BEFORE_5.16.2> sudo dnf versionlock add oracle-optimization

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
