AccelUtils
• Collaboration between:
– BNL: Gabriele Carcassi, Kunal Shroff
– MSU: Eric Berryman, Robert Gaul
– HZB/BESSY II: Ralph Lange
• Umbrella project for:
– ChannelFinder
– Olog
– future projects
Overall vision
• Provide tools for accelerator operation
• Using Service Oriented Architecture
– Provides decoupling and ability to update while in production
– The service and the protocol is the main contract where
compatibility is kept (not the database, api, etc…)
• Using web technologies for the server
– Very solid support from industry
– Work with firewalls
• Use-case driven
– Start from a need not from technology
• Focused on deliverables products
– Something you can download and install
Looking for people
•
•
•
•
•
•
That work well with others
Share the architecture vision
Task focused
Deliverable oriented
With a need to solve
Various level of expertise are welcome
– Could use this as a learning experience
• That work well with others
Infrastructure
• Continuous build/test infrastructure
• Each subproject is on both sourceforge and
java.net
– Sourforge: website, wiki, mercurial repository
– Java.net: JIRA bug tracking
• We (should) have a once a month meeting
– Round the table, what I have released past month,
what I’ll be working next month
– Inpromptu meetings with Google hangout
Server technologies
• More requirements on how services are done
– It’s the important part
– Multiple people need to be able to support it
– Should be homogeneous
• All installable in a cluster with similar configuration
• Standardize on Java EE
– Using Glassfish (standard implementation)
– Still haven’t standardized on internals
• JDBC vs JPA or JAX-RS or …
Client technologies
• Whatever you want!
– Php/Ruby/… for web ui
– Python for scripts or uis with pyQt
– Java for CSS, Swing uis, applets, Android
– Objective C for Apple
– As long the end product is buildable from
command line, packaged, deployable and
functional
Laundry list
• Move build/test infrastructure out of BNL
– In the cloud!
• Factor out common parts
– Server authorization scheme
– Client side configuration management
– Client side connection management
• Single sign on
– Authenticate once for all applications
– Integrate with Linux and/or Windows logon
– Forward credentials for web ui
Laundry list
• Support different databases
– Move database layer to JPA
– Provide different scripts
– Setup test infrastructure
• Support different application servers (jboss,
websphere, …)
– Setup test infrastructure
Wish list
• Equipment status and schedule management
– Something along the lines of ISA 95 part 2
• Lock Out Tag Out service
– Manages requests for locking devices during
maintenance
• Other services
– Do you have another service that fits the
architecture and spirit? Let us know!
