• Matt Ford for OGSA-DAI and Oracle slides taken from his presentations for the NGS Induction
Workshop (Dec. 2004, NeSC)
• Peter Berrisford for SRB slides

• OGSA-DAI: database access and integration
– grid-enabled database access….
• The Storage Resource Broker:
– virtual file system for distributed file systems
– Replica files in different locations, catalogue service to find them.
• GridFTP: large file transfer
• But first….
7

• The NGS core nodes, from the outset, have been partitioned into compute and data clusters.
• As the NGS matures the requirement for data hosting will grow
• Oracle database: a backend for both users and services offered by the NGS.
• The RAL and Manchester sites are designated as the data clusters with each site having the ability to dedicate up to eight nodes for use by Oracle.

Support
• Additional application needed after joining the
NGS
• All enquiries and production support for the
Oracle service is via the Grid Operations
Support Centre ( GOSC )
– 9-5 Operational support (monitoring, notification, maintenance) other times best endeavours basis.

• The Open Grid Services Architecture Data Access and
Integration project is concerned with constructing middleware to assist with access and integration of data from separate data sources via the grid.
• The project was conceived by the UK Database Task
Force and is working closely with the Global Grid Forum
DAIS-WG and the Globus team.
10

• the OGSA-DAI deployment on the NGS is being actively developed
• users should expect that procedures may change – it does not reflect the commitment NGS has to providing a service.
• Initially the Manchester JISC data cluster has been charged with deploying the OGSA-DAI service
