7 How to Use the Object Type Translator Utility This chapter discusses the Object Type Translator (OTT) utility, which is used to map database object types, LOB types, and named collection types to C structures and C++ class declarations for use in OCCI, OCI, and Pro*C/C++ applications. Note: JDK 1.3.1 compatible Java copiler and Java interpreter must be correctly installed. This chapter includes the following topics: ■ How to Use the OTT Utility ■ Creating Types in the Database ■ Invoking the OTT Utility ■ Overview of the INTYPE File ■ OTT Utility Datatype Mappings ■ Overview of the OUTTYPE File ■ The OTT Utility and OCCI Applications ■ Carrying Forward User Added Code ■ Example OCCI Application ■ OTT Utility Reference How to Use the Object Type Translator Utility 7-1
