Database drivers changes

New and desupported database drivers.

New database server versions supported in Genero 6.00:

  • Support for Informix 15 by using the Informix CSDK 15 client environment. In a previous version, Informix 15 could only be accessed with Informix CSDK 4.50.

New database clients supported in Genero 6.00:

  • Support for Informix CSDK 15 with new dbmifx_15 ODI driver.
    Important:
    For many Genero BDL versions, there was only one Informix ODI driver available, with the name dbmifx_9, compatible with CSDK versions 4.10 and 4.50. Starting with Genero BDL 6.00, as the CSDK 15 libraries are not compatible with older CSDK libraries, Genero provides now two distinct Informix ODI drivers:
    • dbmifx_9, compatible with Informix CSDK 4.10 - 4.50.
    • dbmifx_15, compatible with Informix CSDK 15 - which is now the default in V6.00!
    Make sure that the ODI driver selected during the installation (or configured manually in FGLPROFILE), matches your Informix CSDK version.

    The default ODI driver can be selected during the Genero BDL installation process.

    Tip:

    Informix 15 uses by default large tables (onconfig TABLE_SIZE LARGE). This server parameter impacts the size of ROWIDs (8 bytes long with large tables). To get 4-bytes ROWIDs, use TABLE_SIZE SMALL, as suggested in Informix setup recommendations.

For more details about new database drivers, see Database driver specification (driver).
