GIOD - Database Tests (I)
- Results
- Application is platform independent
- Database is platform independent
- No performance loss for remote client
- Fastest access: objects are “indexed”
- Slowest: using predicates
Developed simple scaling test application:
Looked at usability, efficiency and scalability while varying
- number of objects
- location of objects
- object selection mechanism
- database host platform
Tested creating federated database in HPSS managed storage, using an NFS export
- Can use HPSS/NFS interface to store databases, but performance poor and timeouts a problem
-
Tested database replication from CERN to Caltech
- Remote database replication transparent given sufficient bandwidth
