LCG_Util and GFAL developer notes

Test and development environment

To run test, you must set up some environment variables. I list the minimum, with examples that can be used immediately at CERN, in the IT-GT-DMS section:

export LCG_GFAL_INFOSYS=lxbra2306.cern.ch:2170
export LFC_HOST=lxb7608v3.cern.ch
export LCG_GFAL_VO=dteam

To get the up-to-date values, see the node status in the certification testbed page (TestBedCERN section).

In addition, create a similar configuration in your development environment (example from my environment, based on practice...):

# Edit this, pointing to your etics workspace
WS_ROOT=/home/molnarzs/workspace/GFAL/

export MANPATH=$MANPATH:$WS_ROOT/stage/man:$WS_ROOT/org.glite.data.gfal/etics-tmp/share/man/:$WS_ROOT/org.glite.data.dm-util/etics-tmp/share/man:$WS_ROOT/org.glite.data.delegation-cli/etics-tmp/share/man/

export PATH=$PATH:$WS_ROOT/stage/bin:$WS_ROOT/org.glite.data/bin
export PYTHONPATH=$PYTHONPATH:$WS_ROOT/stage/lib/python2.5/site-packages/

It is also advised that you execute the following script from your workspace root:

org.glite.data/bin/e-env

Working in a virtual node

If you want debug/develop in a virtual node from the DMTestBed, read this document.
