AliEn Database issues

• Pablo Saiz

- overview over current DB structure, what tables are important which ones obsolete ? - upgrade to AliEn v219, what are the main changes in the DB ? - how changes in the database or data structure should be distributed (and how existing databases can be upgraded)

tight connection of AliEn to external software

• Florian Uhlig

- too tight connection to external software may be a problem for new VOs. - setup of AliEn is relatively easy, but setting up a ML repository did not work for new VOs without direct help from Costin. No corresponding manual or howto available for doing this from scratch - removal of SE service as site service: it was handy to have an AliEn service which takes care of xroot configuration and startup. If new VOs have also to install xrootd additionally on each site this is an additional obstacle - generally the obstacle for startup with AliEn Grid seems to become higher and higher for new VOs

hardwired code components in AliEn

• Florian Uhlig
