Preparing to create opaque types and UDRs

Before you begin

Before using the UDT and UDR Manager facility, perform the following setup tasks:
  • Make sure your database server supports Java.

    The UDT and UDR Manager facility does not work in legacy servers that do not include Java support.

  • Include either the ifxtools.jar or ifxtools_g.jar file in your CLASSPATH setting.
  • Create a directory named /usr/informix in the database server, with owner and group set to user informix and permissions set to 777.
  • Add the following entry to the /etc/group file in the database server:
    informix::unique-id-number:
  • Check the release notes for the driver and database server for any further limitations in this release.
