ibm datapower gateway UPGRADE

Affected: >= 11.0.0.0 and < 11.0.0.3

Fixed in: 11.0.0.3

Safe to downgrade to: a release before 11.0.0.0

1. Check installed version

apt-cache policy datapower-gateway || rpm -q datapower-gateway || datapower-gateway --version

2. UPGRADE to 11.0.0.3 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade datapower-gateway

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade datapower-gateway

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 11.0.0.0 (Debian / Ubuntu)

apt-cache madison datapower-gateway sudo apt install datapower-gateway=<VERSION_BEFORE_11.0.0.0> sudo apt-mark hold datapower-gateway

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list datapower-gateway sudo dnf downgrade datapower-gateway-<VERSION_BEFORE_11.0.0.0> sudo dnf versionlock add datapower-gateway

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.
