2. ICALEPCS 2005 Archamp 08 – 09 October, 2005 2nd ALMA Common Software Workshop ACS and Laser ACS AS built on top of Laser AS Keep the same API Reuse the Laser Alarm Console Reimplementation of Laser interfaces Persistence not yet implemented

3. ICALEPCS 2005 Archamp 08 – 09 October, 2005 2nd ALMA Common Software Workshop 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

4. ICALEPCS 2005 Archamp 08 – 09 October, 2005 2nd ALMA Common Software Workshop 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

5. ICALEPCS 2005 Archamp 08 – 09 October, 2005 2nd ALMA Common Software Workshop 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...
