How Meridian Works With Oracle
Meridian works with Oracle using two intermediate Meridian components:
-
Object cache (<DatabaseEngine>ORA.dll) — A database-dependent cache that optimizes queries to Oracle.
-
ORAIO driver (HTORAIO.dll) — An Oracle-specific component that interfaces between the object cache and Oracle.
The relationships between these components are illustrated in the following figure.
When a Meridian client sends or requests data from the Meridian application server, the EDM Server service communicates with the object cache , which in turn communicates with ORAIO, which then communicates with Oracle on the Oracle server.
