The describes how to use the HCL Informix® to load and unload large quantities of data efficiently to or from Informix databases.
Examples of loading and unloading jobs using the ipload utility
This section shows how the components of the fit together. The section includes a step-by-step tutorial with two examples (for a load and an unload job) that use the ipload graphical user interface (GUI).
Device-Array windows
A device array is a collection of files, tape devices, and pipes that onpload uses for input and output. Pipes are only supported on UNIX™. You can create a device array and specify the location of the input data from the Device Array Selection and Device-Array Definition windows.

      This section shows how the components of the fit together. The section includes a step-by-step tutorial with two examples (for a load and an unload job) that use the ipload graphical user interface (GUI).
      - Prepare to use the ipload utility
        The ipload utility is a part of UNIX™ database servers. Before you can use ipload, you must have installed the database server. If the database that you want to load or unload is on the computer where you plan to run ipload, you must also start the database server.
      - Create a file of data
      - Create a database
      - The ipload utility
        The uses information from the onpload database to control loading and unloading of data. Theoretically, you could create the onpload database and use DB-Acess or some other database tool to populate it. However, it is recommended that you always use ipload to manage the onpload database.

      - Map Views window
        From the Map Views window, you can create a map that specifies which data field from the input file (/work/mydata) is entered into which columns in the database table.
      - Completing the Load Record Maps window
        The Load Record Maps window specifies the device array that holds the input data, the format that describes the input data, and the database and table where the input data will be stored.

Device-Array windows

A device array is a collection of files, tape devices, and pipes that onpload uses for input and output. Pipes are only supported on UNIX™. You can create a device array and specify the location of the input data from the Device Array Selection and Device-Array Definition windows.

In this example, the input data is the /work/mydata file that you created in Create a file of data.
