Summary of data management meeting Monday, March 29th, 2004 16:00 Bat 2-R030
==============================================================================

Workload Management System (Ian, Vincent):
- WMS is capable now of using several batch systems
- Output file entries are stored in Alien catalog
- Output files are automatically transferred to
  the local storage element.
- Monitoring is integrated
- The central information service needs some cleanup
  before the final installation.
- The service is now running without problems on lbnts1

Monitoring and accounting:
- WMS info is not yet automatically moved into the accounting.
- A policy is needed for the automatic movement of the monitoring
  information into the accounting database.
- Manuel asked for input/comments to the monitoring web interface.
  People are invited to try them.

Data management tools/issues:
- Access to the production testbed is now granted
  and software installation is possible.
  The procedure works for most sites:
  - KA, Spain, RAL and LCG-PBS ok.
  - NIKHEF and LCG-LSF: write access possible, but still problems
    with permissions
- Software is installed using a tag of the form:
  LCG_<VO>_<Application>_V<version-number>
  It was recommended to use LCG tools for the software 
  installation, which is problematic since we want to install 
  software on a project bases.
- A tool is necessary to find out if software of a given
  project/version is installed on a given site.
- A policy is needed for the individual TierXX centres
  for storing the output data.
- Also "special file types" need to be defined for 
  diffeent treatment for e.g. data and log files.
- It is difficult to find a version of gridftp, which
  does not depend on many libraries. Since several sites
  are only accessible through grisftp, a solution must be found.


POOL:
- The problem seen with POOL using mysql libraries is solved.
  These libraries are not needed, the link dependency was
  atrificially introduced through the POOL interface package.
- XML catalog slicing tool should use a common interface
  implemented by the bookkeeping catalog and the Alien
  catalog.
