This Technical Note accompanies an updated version of the OCI Mapper component, which was introduced in Technical Note 03-44, “Migrating from 4D for Oracle to 4D for OCI using OCI Mapper”. The main focus of this Technical Note is to summarize the updates that have been made to the OCI Mapper and provide more insight into 4D for OCI programming, both on its own, and in comparison to 4D Oracle. Installation procedures for the OCI Mapper component are included.

This Technical Note is the first part of a two-part OCI Mapper update. In the next part of the release a debug version of the OCI Mapper will be provided. This version will feature the logging of OCI Mapper methods as well as 4D for OCI calls to a text file in order to facilitate advanced analysis of 4D for OCI programming problems. The reason for the two-part release is the debugging code tends to make the OCI
Mapper methods harder to read.
