The ORACLE based version is only supported by meta-rpms. dCache 1.5 the configuration contains several fixes and enhancements provided by GridPP gfal 1.6.1 supporting secure rfio. If you upgrade your DPM you have to upgrade your local clients (WNs and UIs) to this version. This includes the update to GSOAP 2.6. lcg-utils 1.2.10 lcg-info-gridftp this is a sensor for gridFTP logfiles that allows to monitor the transfers from a globus2 gridFTP server YAIM based on lcg-yaim-2.4.0-4 with additions for the new components. Who should install what? =================== Every SC3 site should install the FTS clients and make sure that the site provides access to a SRM enabled SE. If the sites provided in the past a Classic SE only the SE can be converted to a DPM based SE or a new dCache SE can be setup. The T1 centers with associated T2s and the T0 should setup FTS servers, or make sure that their installation is at the same version as the release. Initially all T1s and later all T2s should setup LFC catalogues. All the remaining client libs. should be upgraded. Where to start? ============ The release is, as always, distributed via the LCG release page: http://lcg.web.cern.ch/LCG/Sites/releases.html For this SC3 specific release we recommend to consult in addition the service challenge web page: https://uimon.cern.ch/twiki/bin/view/LCG/LCGServiceChallenges markus
