LCG File Catalog
From GridPPwiki
The LFC (or LCG File Catalog) has been developed by LCG (http://lcg.web.cern.ch/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 .

Installation
It's easiest to install the LFC on a single box using YAIM, but you can share the LFC with other LCG components as well.
- Installing a site-local LFC with YAIM.
- Installing on a pre-existing LCG box.
- Using your LFC with MySQL on a different host.

Once the LFC is installed you should test it:

- Testing the LFC namserver functions.
- LFC local catalog registration tests.

Care and Feeding
- Adding extra VOs to the LFC.
- LFC Certificates.
- Once you publish the catalog it's vital to make MySQL Backups of the database.

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 (https://uimon.cern.ch/twiki/bin/view/LCG/LfcAdminGuide). 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.
