PCa. PAC 2008 Requirements • Several sources for alarm/log messages (EPICS, D 3, CSS, …) • Dedicated alarm messages should be forwarded to different destinations (SMS, e-mail, voice mail, …) • Rules and actions to configure special behavior for alarm messages • Persistent store holds current status of all process variables • Archive all alarm/log messages • Operating system independent applications to view messages and configure alarm system Jan Hatje, DESY AMS – Alarm Management System 3

PCa. PAC 2008 Technical Overview • Implementation in Java → Operating System independent • Alarm applications with UI part are integrated in Control System Studio (CSS) • Headless alarm applications are based on CSS platform • Common APIs for JMS -, LDAP – Server and Database → no special implementation is required • JMS Messages (Key, Value) for all communication between components • Redundancy for JMS communication and Alarm Management System Jan Hatje, DESY AMS – Alarm Management System 5

PCa. PAC 2008 Persistent store and archive II • Persistent Store (LDAP) holds structured list of all records • Records are ordered by facility name, component and controller • Alarm status of a record: – – epics. Alarm. Ackn. Time. Stamp epics. Alarm. Severity epics. Alarm. Status epics. Alarm. Time. Stamp • Jms 2 Ora is a CSS headless applications • JDBC for DB connection → Jms 2 Ora can use any DB implementation Jan Hatje, DESY AMS – Alarm Management System 9
