Timeline

ibm operational decision manager DOWNGRADE
Affected: 8.10.3 · 8.10.4 · 8.10.5.1 · 8.11 · 8.11.0.1 · 8.12.0.1
Fixed in: no fixed release known
Safe to downgrade to: a release before 8.10.3
1. Check installed version
apt-cache policy operational-decision-manager || rpm -q operational-decision-manager || operational-decision-manager --version
2. No fixed release: DOWNGRADE to a release before 8.10.3 (Debian / Ubuntu)
apt-cache madison operational-decision-manager sudo apt install operational-decision-manager=<VERSION_BEFORE_8.10.3> sudo apt-mark hold operational-decision-manager
2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)
dnf --showduplicates list operational-decision-manager sudo dnf downgrade operational-decision-manager-<VERSION_BEFORE_8.10.3> sudo dnf versionlock add operational-decision-manager
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.
