ibm websphere application server UPGRADE

Affected: >= 17.0.0.3 and < 26.0.0.8

Fixed in: 26.0.0.8

Safe to downgrade to: a release before 17.0.0.3

1. Check installed version

apt-cache policy websphere-application-server || rpm -q websphere-application-server || websphere-application-server --version

2. UPGRADE to 26.0.0.8 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade websphere-application-server

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade websphere-application-server

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 17.0.0.3 (Debian / Ubuntu)

apt-cache madison websphere-application-server sudo apt install websphere-application-server=<VERSION_BEFORE_17.0.0.3> sudo apt-mark hold websphere-application-server

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

dnf --showduplicates list websphere-application-server sudo dnf downgrade websphere-application-server-<VERSION_BEFORE_17.0.0.3> sudo dnf versionlock add websphere-application-server

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.
