4. Controls Group Spring 2003 EPICS Collaboration 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. Controls Group Spring 2003 EPICS Collaboration 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)

9. Controls Group Spring 2003 EPICS Collaboration 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. Controls Group Spring 2003 EPICS Collaboration Transportability  Entire system  Engine  Data Store  History server  CADataStore API  CORBA API

11. Controls Group Spring 2003 EPICS Collaboration 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. Controls Group Spring 2003 EPICS Collaboration In the Works  Data transformation API  Darth 1.0  Public History API specification, IDL  Insertion API for externally acquired data
