The European X-Ray Laser Project XFEL X-Ray Free-Electron Laser Setting up a Name Server for EPICS IOCs 1. Create a list of records from the IOC during boot time • Create a file in your preferred directory on the file server with the name: logical. Ioc. Name 2. Create IOCpathes file specifying the LDAP structure. • At DESY the file is created by a script which is crawling through the IOC boot directories. 3. Run ldap. Updater – a CSS headless application • ldap. Updater will use the files mentioned above create LDAP sub-trees and write record names to the LDAP tree Matthias Clausen, DESY CSS Presentation @ GSI Feb. 2009: CSS Namespace Browser and CSS Tools 3

The European X-Ray Laser Project XFEL X-Ray Free-Electron Laser Namespace Browser Plugin to Display Hierarchical Name Configurations Two Implementations: EPICS: • The EPICS names are stored in an LDAP server • The Structure has three levels: Facility | IOC | Record • Clicking on the last Element (Record) will activate the Contribution Menu -> Activate other plugins passing the record name. TINE (DESY): • TINE names are stored in TINE name server • The Structure has three levels: Facility | IOC | Record • Clicking on the last Element (Record) will activate the Contribution Menu -> Activate other plugins passing the record name.
