  1. CZAR 2.0 (in development) Christopher A. Larrieu Chris Slominski

  2. Components • Configuration Database • Data logging engine • Data store (Embedded Database) • History data server • Configuration management GUI • Engine control / monitor GUI • History data retrieval clients • Command-line control/config tools

  3. System Overview Oracle 9i MySQL 4 XML Configuration Manager OCI Xerces CORBA DAQ Engine C++ History Server CORBA CORBA Manager GUI Data Store XARR CORBA Berkeley DB StripTool Command-line Tools Filesystem hapiget DARTH

  4. New Stuff • Oracle or MySQL for configuration database • Berkeley DB for data store • Embedded database • Reasonable open-source license • Import legacy data • Data compression (6 TB / year  .8 TB / year) • 84% lossless • 92%, truncating timestamps to milliseconds • Improved command-line tools • Expiration dates for logging requests

  5. History Clients • XARR • Pure CORBA client • hapiget command-line tool • Script applications • StripTool • CORBA client in separate thread • DARTH (Java) • Extensive configuration • Flexible display (graph, table, correlation)

  6. DARTH

  7. Status • Version 1.0 • operational since January 2002 • ~ 23,000 signals • ~ 3.6Gb / day raw; processed: 1Gb • HP-UX 11  Solaris 8 in June 2002 • Version 2.0 • Solaris 8  Linux 7.3 July 2003 • ~ 3.6Gb / day raw; processed: ~360Mb

  8. Linux archiving system

  9. More Status • Import config files from ChannelArchiver, old AR • New configuration and install scripts • > emacs config/prefs/myprefs.mk • > make build; make install • Init scripts for starting / stopping / inspecting entire system in standard unix fashion • > rc.czar start • HP-UX 11 aCC, Solaris 8 CC, Linux (g++ 3.2) • ACE/TAO 5.2.1 • Berkeley DB (SleepyCat)

  10. Transportability • Entire system • Engine • Data Store • History server • CADataStore API • CORBA API

  11. Scalability • Data store decoupled from data acquisition • multiple engines can spool data • Embedded database indexes, summarizes data • fast lookup • easily shuffle data offline/online • fast retrieval • History server • reduce data before transporting

  12. In the Works • Data transformation API • Darth 1.0 • Public History API specification, IDL • Insertion API for externally acquired data
