Here are the details of the Replication setup at CERN, for handover of the LFC replication tests.

LFC servers

Three LFC servers at CERN have been setup for the LHCb replication tests :

  • lxb0716.cern.ch
  • lxb0717.cern.ch
  • lxb1540.cern.ch

The Oracle account used for each is specified in /opt/lcg/etc/NSCONFIG.

To get access to these servers, contact Miguel Coelho.

Oracle accounts

Streams

Three accounts had been originally setup for the Streams tests :

  • lcg_lfc_3d_lhcb@strmtest
  • lcg_lfc_3d_lhcb_10m@strmtest
  • lcg_lfc_3d_lhcb_100m@strmtest

Materialized Views

Three accounts had been originally setup for the Streams tests :

  • lcg_lfc_mv_lhcb@strmtest
  • lcg_lfc_mv_lhcb_10m@strmtest
  • lcg_lfc_mv_lhcb_100m@strmtest

LFC population

To populate the LFC servers, use /afs/cern.ch/user/v/vagnoni/public/lfcfill.tar.gz.

Untar this file, and go to the lfc/ directory.

Modfy the following variables in start.sh according to your needs :

export LFC_HOST=lxb0717.cern.ch
export NTHREAD=40
export NLFNPERTHREAD=1000000

To start/stop the tests :

./start.sh
./stop.sh

For help regarding the population scripts, contact Vincenzo Vagnoni.
