Understanding how Meridian works with Oracle

Meridian works with Oracle using two intermediate Meridian components:

• Object cache (ObjectSetORA.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 all of 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.
