2. Information Services in EGEE, 31 January 2005 - 2 Whats the talk about? Past - Recent Activities Present - R-GMA for GLite Release 1 Future - RGMA developments

3. Information Services in EGEE, 31 January 2005 - 3 Recent Activities Apel used for accounting in LCG New API Grid Journal Paper accepted EGC2005 poster accepted Bug-fix release for LCG

4. Information Services in EGEE, 31 January 2005 - 4 R-GMA LCG Bug-fix Release Registry replication Each instance is master of its own data Checksums to support self healing Can adjust the frequency of updates Need to discover the optimum number of instances Provides: Removal of single point of failure Better performance Simpler API – matching the next (WS) release Provides smooth transition between old API and WS A lot of work has gone into avoiding problems caused by poorly configured networks, firewalls, MySQL corruptions etc – i.e. coping with life on the Grid Some predefined indices for performance Expect release to be rolled out around end of February

5. Information Services in EGEE, 31 January 2005 - 5 Deployment in LCG 105 sites on LCG R-GMA working sites at 40 sites 26 sites failing GOC R-GMA tests Configuration script not run Firewalls blocked All working UK sites are passing the GOC R-GMA tests

6. Information Services in EGEE, 31 January 2005 - 6 R-GMA for GLite Release 1 Very similar to LCG release Based on old API with wrappers Authentication

7. Information Services in EGEE, 31 January 2005 - 7 Service Discovery API using R-GMA Prototype available with GLite Release 1 Java and C In development May provide a service rather than just API (wrapper) API being discussed with PPDG Hope to agree on common API User guide http://hepunx.rl.ac.uk/egee/jra1-uk/glite/doc/index.html

9. Information Services in EGEE, 31 January 2005 - 9 Towards Web Services Web Service version Version with pre-WS functionality almost ready Design documentation and review

10. Information Services in EGEE, 31 January 2005 - 10 RGMA developments File (as well as memory and RDBMS) based Producers Native python interface Portable i.e. no swig dependency Fine grained authorization Will use parameterised views to control: Who can publish Who can read Who can create table Who can drop table etc.

11. Information Services in EGEE, 31 January 2005 - 11 RGMA developments Schema replication Eliminates remaining single point of failure Novel algorithm No master Allows reuse of table names
