5. 2006 EPICS Collaboration Meeting Background Currently, configuration data (.db,.dbd, template and substitution files) are distributed around our network. IOCs can get data from different sources. Revision Control Live data in EPICS Various points of entry Keeping PV data consistent can be difficult Ideally, information would be stored in single central repository.

6. 2006 EPICS Collaboration Meeting Advantages Many noted in IRMIS Primer Data Validation Offer single point of entry in to system for a given task Others….

7. 2006 EPICS Collaboration Meeting Goals Extend our IRMIS-based system Define a generic framework Solicit input to enhance portability Leverage existing progress

8. 2006 EPICS Collaboration Meeting Functional Requirements Methods of importing and modifying existing data (a la IRMIS). Mechanism to make startup information available for IOCs. Revision control and release management procedures and interface(s). EPICS layer to adjust real-time values. Database abstraction layer All the while, ensuring settings are consistent across facility.

11. 2006 EPICS Collaboration Meeting Design

12. 2006 EPICS Collaboration Meeting Conclusion We have a way to go in generating our requirements and starting design. We hope to develop some relationships during this meeting. Given the technology available, my slide presentations could be more exciting.
