RDB Channel Archiver

• An EPICS extension toolset for data archiving
• EPICS (Experimental Physics and Industrial Control System) is a

set of open source software tools to create real-time control systems for scientific instruments such as particle accelerators.

• Upgrade of the original Channel Archiver
• Data stored in a relational database (RDB): MySQL and Oracle

are supported

• Tools written in JAVA instead of C++
• Data accessed through the Control System Studio (CSS) Data Browser
• CSS builds on Eclipse
• CSS provides a common platform for new control system

applications as Eclipse plugins

• Developed by Kay Kasemir at Oak Ridge National Laboratory

CSS-based OPI ArchiveEngine config.xml IOC RDB (Oracle/MySQL)

Other tools for config & samples

Why RDB Channel Archiver?

• State of art programming techniques

providing a great upgrade of archiving speed

• Developed and maintained data browser

available as part of an integrated control system applications toolset, CSS

• Modern user interface
• Better data management with Relational

Database and potentials for further developments

Goals & Progress

• Setup the RDB Channel Archiver on a test

computer and experiment with bogus local IOC servers and/or physical signal generators

• Compile the plugins and associate

configurations into the APS version of CSS

• Currently have the database setup but needs

to work on the table structure;

• Start building the archive engine
