Architecture Overview of the iWay Log Event Adapter for Informix
The following diagram illustrates the architecture of
the iWay Log Event Adapter for Informix.
iWay Informix CDC Agent listens and reads the Informix Logical
Log for INSERT, UPDATE, DELETE records using the Informix Change
Data Capture (CDC) API.
The iWay Informix CDC Agent processes the records, composes
the corresponding ANSI SQL statements, and then writes them into
an Output CDC Data File.
iWay Log Event Listener listens to the Output CDC Data File
and reads the SQL statements record by record.
iWay Log Event Listener transforms every SQL statement and feeds
the iWay CDC SQL Batch Agent.
iWay CDC SQL Batch Agent applies SQL statements (INSERT, UPDATE,
DELETE) to the target Oracle database tables.
