WARNING: information not up-to-date

The LFC front ends at RAL Tier1 are installed on lfc0448.gridpp.rl.ac.uk and lcglfc0449.gridpp.rl.ac.uk

There is also a read-only LFC instance (lcglfc0377.gridpp.rl.ac.uk) solely for LHCb use.

Monitoring

Local Deployment Information

The first LFC server at RAL (lfc0448.gridpp.rl.ac.uk) was installed following mainly the instructions in LFC Admin Guide. One difference though: it uses a remote MySQL server (see MySQL on a different host).

In April 2008, the MySQL backend was migrated to an Oracle backend.

There are two LFC servers at RAL shared by all the supported VOs (except LHCb which have their own read-only LFC instance, lcglfc0377). The two general LFC front ends can be load-balanced by using the lfc.gridpp.rl.ac.uk alias (this DNS alias points to both IP addresses of lfc0448 and lcglfc0449)

A dedicated LFC server (with Oracle backend) is installed for LHCb use (December 2007).

The list of VOs can be found out with
