LCG File Catalog
From GridPP Wiki
The LFC (or LCG File Catalog) has been developed by LCG to resolve problems with the EDG Replica Manager File Catalog.
Tier 2s need to install a local version of the LFC catalog, as set out in Tier 2 DM Requirements. Why is this necessary? This site-local catalog fits into some of the VOs data processing models and provides adds new generic middleware service to LCG .

HOWTOs and Install Guides
- The GOC Wiki also contains a useful page: http://goc.grid.sinica.edu.tw/gocwiki/How_to_set_up_an_LFC_service
- The LFC Administrators Guide. Note that most of the install steps described here are actually performed by YAIM, however it provides a good overview and will help if things don't go quite according to plan.
Presentations on the LFC
- At CERN SC 3 Workshop (April 2005).
- At London SC 3 Workshop (May 2005).
