New Architecture (cont.)
Rationale behind Split
- “Mirroring“
- “back-to-back” replication between machines for fail-over
- Load-Sharing
- insert, collect (Abcoude)
- user queries, interactive performance (Halfweg)
- Maintenance and Backups without Affecting Users
- e.g. backup to tape drive without affecting users by switching user dbase queries to other machine
New Insertion Script (In Progress)
- Intelligent Job Processing (prevent multiple inserts of data, limit load on dBase)
- Time-Independent
