Question: Does Informix have a construct equivalent to Oracle’s ‘materialized view’ or is there a better way to synchronize two tables (not DB’s) accross a DB link? I could write a sync myself (was asked to) but that seems like re-inventing the wheel.
Background: Recently we had to split (one part of DB one one server, the other part on the other server) a monolithic Informix 9.30 DB (Valent’s MPM) since the combination of AppServer and DB server couldn’t handle the load anymore.
In doing this we had to split a user defined table space (KPI Repository) aranged in a star shema of huge fact tables and well defined dimension tables.
Unfortunately a telco manager decided to centralize the dimension tables (Normalization, no data redundancy, no coding needed) on one machine and thus make them available as views over a DB-link on the other machine. This is both slow and unstable, as it every now and then crashes the DB server if the view is used in sub-queries (demonstrable), very uncool on a producton server
I may be getting your requirements but could you not just use enterprise replication to replicate the single table across the DB’s?
