Unload

The online Unload function is used to unload data from an FDIC in Migrate format. The scope of this function is determined by one or more extracts. It is not possible to specify individual objects.

Using commands you can also write individual objects to the Coordinator FDIC in Migrate format.

This section covers the following topics:


Calling the Online Function

Call the function by entering code U in the Coordinator Main Menu.

Parameters
Extract ID Up to ten extracts can be specified. You can enter an asterisk to select an extract from a list. The No. column displays the number of objects contained in the extract.
Unload options These are described in detail below.
Build set for unloading The following types of data can be unloaded without using extracts. The column No. on the right indicates the number of metadata object types, retrieval models and XRef data members which will be unloaded.
  • Metadata
    • Y
      An additional screen appears in which you can specify the metadata to be unloaded. See Unloading Metadata.

  • Retrieval models
  • XRef data
    • Y
      An additional screen appears in which you can specify the XRef data to be unloaded. See Unloading XRef Data.

Unload Methods

There are two methods of unloading Predict objects:

  • Using extracts. Using the menu functions, you can only unload objects that are contained in an extract. Up to ten extracts can be specified for one unload operation. For more information see the section Extract in the Predefined Object Types in Predict documentation.

  • Using unload commands. In the command line you can also specify individual objects or ranges of objects. The scope of the function can be limited by parameters. See Overview of Command Keywords.

Unload Options

With Code

Applies to the following Predict-owned external objects connected to Predict file objects:

  • DDMs

  • Copy code members

  • Card formats such as ADAWAN, ADACMP.

If this parameter is set to Y, the connected external objects will be unloaded together with the file object only if the file has not been modified since generation.

If this parameter is set to M, the connected external objects will be unloaded even if the file object has been modified after generation.

With Profile

Applies to objects of type user: If this parameter is set to Y, Predict and LIST XREF profiles are unloaded, too.

With Internal ID

Determines whether objects are unloaded with or without Internal ID. See Internal ID.

If this parameter is set to Y, an object is unloaded with its internal ID. An object with the same internal ID is added in the target environment. The object remains coupled with the object in the source environment by means of this internal ID.

If this parameter is set to N, an object is unloaded without its internal ID. An object with a new internal ID is added in the target environment. The object is no longer coupled with the object in the source environment.

Include Extracts

If this parameter is set to Y, the extract(s) used for the Unload function will also be unloaded.

Target Environment

Data can be unloaded to the following environments:

  • 84
    Predict 8.5 Data is unloaded in Migrate 8.4 format.

  • 85
    Predict 8.5 Data is unloaded in Migrate 8.5 format.

Create Report Listing

If this parameter is set to Y (default), a report listing of type UNL is created on the Main FDIC.

Unloading Objects with Commands

With Unload commands you can unload objects of different types selectively. The command used depends on the object type.

Specifying the Object Type

The following rules apply when an object type is required for a migrate command:

Specify the object type as two-character code or long name of a Predict object type (predefined or user-defined).

For example:

UNLOAD OBJECTTYPE PR

or

UNLOAD OBJECTTYPE PROGRAM

will unload objects of type program.

  • retrieval model AL for object types program and system

  • XRef data for file number 99 on database 123

  • objects contained in Extracts EXT-1 and EXT-2, together with

    • any Predict-owned external objects connected to Files contained in the Extracts

    • the Predict and LIST XREF profiles of any Users contained in the Extracts

   UNLOAD METADATA ALL,FROM-DATE=2013-05-31_00:00
   UNLOAD RETRIEVALMODEL PR,ID=AL
   UNLOAD RETRIEVALMODEL SY,ID=AL

   UNLOAD EXTRACT EXTRACT1=EXT-1,EXTRACT2=EXT-2,CODE=Y,PROFILE=Y
  

See also section Data Transfer Examples in this documentation.

Unloading Internal IDs

If you are working with more than one FDIC file, it is strongly recommended that you consolidate the Internal IDs of the objects at your site. After you have unloaded the objects you wish to consolidate, execute the function Load Internal ID as described on Importing Internal IDs.

You can unload the Internal IDs of all objects or any subset of objects. However, it is not possible to load selectively. All objects on the transfer medium are loaded with their internal IDs.

See also Consolidating Internal IDs in Batch Mode.

Calling the Online Function

Enter code U and object type I in the Coordinator main menu.

Only parameters Extract ID, Include Extracts and Target environment are applicable.

Unloading Internal IDs in Batch Mode

Internal IDs can be unloaded with the command UNLINTERNAL in library SYSDICBE. See Sample Batch Command.
