Learn the essential maintenance workflows for Tungsten Cluster, including safe start/stop procedures, isolating nodes, updating cluster parameters, executing rolling maintenance with controlled switches, and performing in-place software upgrades without unexpected failovers.
This session demonstrates when and how to place the cluster in maintenance, use cctrl datasource shun to isolate nodes, apply configuration changes via tungsten.ini and tpm update, and re-introduce nodes cleanly to preserve availability.
You’ll also follow a step-by-step rolling maintenance plan plus upgrade guidance using tools/tpm update --replace-release, connector handling, and version-safety rules before returning to AUTOMATIC mode.
