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 deactivated, 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.
On the editing screen for an InfoProvider, choose NLS Usage field.. You can make the required setting in the
For the query:
Start Query Designer by choosing.
Select your Query.
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.
Save your entries.
For the analysis process:
You are in the analysis process designer. Select your analysis process.
Go to the editing screen of the InfoProvider data source. Set the flag Read Data from Near-Line Storage.
Save and activate the analysis process.
When the query/analysis process is executed, the data in near-line storage is either read or not read, depending on the settings made.
