High-Performance Loader User's Guide
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).
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.
Check the ipload utility default values
The default values that ipload selects when it is first started specify machine type, character code set for character-type data, and other operating characteristics. In most cases, the only default that you might need to change is the machine type.

      - 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.

      - 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.
        Start the ipload utility
        To start ipload, type the following at the system prompt ipload.
        Choose a project
        You use the by preparing load jobs that import data or unload jobs that export data. You can assign the load and unload jobs to various projects to organize the jobs into functional groups.
        Check the ipload utility default values
        The default values that ipload selects when it is first started specify machine type, character code set for character-type data, and other operating characteristics. In most cases, the only default that you might need to change is the machine type.
        Look at the Defaults window
        Choose Configure > Defaults to see the current default values. After you check the defaults, you can click Cancel to exit from the Defaults window.
        Look at the Machines window
        Choose Configure > Machines to see the current default values. Make sure that the machine type displayed in the Machines window matches the current machine type. Click the Machine > Type down arrow to select a machine type. Click Cancel to exit from the Machines window.
      - Load Job windows
        A load job is a collection of the specific pieces of information that you require to move data from a data file into a database. The Load Job window shows a flowchart that includes all of the components of a load job.
      - 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.
      - Format windows
        The format specifies the organization of the input data.
      - Filter, Discard Records, and Logfile text boxes
        The Load Job window now has entries for a device and format. The next incomplete items in the Load Job window are the Filter text box, the Discard Records text box, and the Logfile text box.
      - 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.
      - Map-Definition window
