What the session covered
- 01
Why the OT server at a terminal must stay up
- 02
Server failover: from the main unit to the standby
- 03
Network redundancy: backup paths and switches
- 04
Database replication to keep transaction data intact
Always-On Terminal was the second Citia Micro-Webinar, a short online session for people who keep fuel terminal systems running. Its subtitle, Triple-Layer Auto Failover: Server, Network & Database, names the three layers it walked through.
A terminal automation system runs on OT servers that host the applications operators use every shift. At Padalarang, for example, the hardware Citia maintains under its TAS lifecycle support includes the TAS server, the FD-Flow PC and the gate interface PC. When one of those machines stops, the work that depends on it stops too.
The session started from that question, why the OT server has to stay up, and then took each layer in turn: moving service from the main server to a standby unit, giving the network a backup path and a backup switch, and replicating the database so transaction records stay complete when a server or link changes over.
For the wider picture of what a TAS does, see the Citia terminal automation system page and the earlier session on TAS and control system reliability.

Common questions
What was Citia Micro-Webinar #02 about?
It covered high availability for OT servers in a terminal automation system. The four topics were why the terminal OT server must stay up, server failover to a standby unit, network redundancy with backup paths and switches, and database replication to keep transaction data intact.
Is there a recording of the Always-On Terminal webinar?
Not yet. Citia has not published a recording or slides for this session, and this page will be updated if either becomes available.
What does triple-layer auto failover mean?
In the session title it means automatic failover on three layers: the server, the network and the database. The server layer moves service to a standby unit, the network layer uses a backup path and switch, and the database layer replicates data so transactions are not lost.
Who was the session for?
Maintenance, instrumentation, automation, IT/OT and terminal operations staff, as listed on the official poster.
When is the next Citia Micro-Webinar?
Micro-Webinar #03 runs on Friday 21 November 2026 at 14.00 WIB on Microsoft Teams. Its topic is troubleshooting motor-operated valves that SCADA cannot read, from the gateway to the field device.
