ACS Alarm system technology

• ACS Component/Container hierarchy based on CORBA replaces J2EE Java Beans

• IDL interfaces replace EJB interfaces

• acsjms implements jms (java messaging system) for ACS on top of CORBA Notification Channel

• ACS CDB for storing AS configuration (In future with ARCHIVE?)

– Hibernate/Spring/Sonic removed

Prototype status

• Code and configuration:✔ ACS modules generated from Laser modules✔ Definition of IDL interfaces✔ ACS specific code reimplements Laser interfaces✔ CDB used to store alarm configurations

• Runtime behavior✔ Java components send alarms by means of Laser API✔ Alarms are reduced in the business tier✔ Alarms are shown in the (partially working) GUI

Remaining list

• Persistence:

– Alarms– User configurations

• Refactoring to make easier two-way propagation changes• Complete missing implementations• CORBA Notification Channel usage optimization• Improve the response time• ...
