ibm infosphere streams DOWNGRADE

Affected: 4.2.1

Fixed in: no fixed release known

Safe to downgrade to: a release before 4.2.1

1. Check installed version

apt-cache policy infosphere-streams || rpm -q infosphere-streams || infosphere-streams --version

2. No fixed release: DOWNGRADE to a release before 4.2.1 (Debian / Ubuntu)

apt-cache madison infosphere-streams sudo apt install infosphere-streams=<VERSION_BEFORE_4.2.1> sudo apt-mark hold infosphere-streams

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

dnf --showduplicates list infosphere-streams sudo dnf downgrade infosphere-streams-<VERSION_BEFORE_4.2.1> sudo dnf versionlock add infosphere-streams

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.
