ibm db2 UPGRADE

Affected: >= 4.8 and < 5.4

Fixed in: 5.4

Safe to downgrade to: a release before 4.8

1. Check installed version

apt-cache policy db2 || rpm -q db2 || db2 --version

2. UPGRADE to 5.4 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade db2

2. UPGRADE (RHEL / Amazon Linux / Fedora)

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 4.8 (Debian / Ubuntu)

apt-cache madison db2 sudo apt install db2=<VERSION_BEFORE_4.8> sudo apt-mark hold db2

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

dnf --showduplicates list db2 sudo dnf downgrade db2-<VERSION_BEFORE_4.8> sudo dnf versionlock add db2

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.
