You can read the data saved in a near-line storage when executing a query or an analysis process.

You can set access to data in near-line storage either in the properties of the InfoProvider or in the properties of the query created on the InfoProvider. You can also create a variable on characteristic 0NEARLINE. This allows you to decide at runtime whether to read from the near-line storage.

In the default setting, access to data in near-line storage is activated, even if a data archiving process with near-line storage exists for an InfoProvider.

In Analysis Process Designer, you can activate InfoProviders for the data source for the purpose of reading the data in near-line storage. In the default setting, access to data in near-line storage is deactivated.

Procedure

InfoProvider:

  1. On the editing screen for an InfoProvider, choose   Extras   InfoProvider Properties   Change  . You can make the desired setting in the NLS Usage field.

For the query:

  1. Start Query Designer by choosing   Business Explorer   Query Designer  .

  2. Select your Query.

  3. Choose    Properties   Advanced  .

  4. Under Usage of Near-line Storage you have various options:

    • Near-line access is deactivated.

      The query does not access the data, even if the data has been stored in a near-line storage. A setting in an InfoProvider (contained in a MultiProvider) that allows this access to occur, overwrites these settings.

      If you have deactivated access in the InfoProvider settings, you cannot activate it again in the query properties.

    • Near-line access is not possible.

      This setting cannot be selected by a user. The setting is only important for the system default, if the relevant InfoProvider type does not support near-line storage or if there is a data archiving process with ADK-based archiving for an InfoProvider.

    • Near-line access is activated.

      Access to data in a near-line storage is possible if

      • there is a data archiving process for the InfoProvider,

      • the InfoProvider is connected to a near-line storage and

      • the selection conditions of the navigation step intersect with the previously archived data area.

        This setting allows access to all the InfoProviders in a MultiProvider that fulfill predefined conditions (even if access is deactivated in an InfoProvider).

    • Near-line access depends on the InfoProvider setting.

      This option is only relevant for a MultiProvider. If this option is activated, the setting for each individual InfoProvider in the MultiProvider comes into effect.

  5. Save your entries.

For the analysis process:

  1. You are in the analysis process designer. Select your analysis process.

  2. Go to the editing screen of the InfoProvider data source. Set the flag Read Data from Near-Line Storage.

  3. Save and activate the analysis process.

Result

When the query/analysis process is executed, the data in near-line storage is either read or not read, depending on the settings made.
