Concepts

This section introduces the infrastructure for creating and executing user-defined routines (UDRs) and applications that you write in Java™ to run in the HCL Informix® database server.

This section provides the following information:
  • Basic characteristics of Java UDRs
  • Basic architecture for executing Java UDRs in the database server
  • Impact of Java UDRs on the database server system catalog tables

For general information about the purpose and the process of developing UDRs for the database server, see the IBM® Informix User-Defined Routines and Data Types Developer's Guide. For information about how to access databases from Java UDRs, see the IBM Informix JDBC Driver Programmer's Guide.
