Administer LASR Tables :: SAS® Visual Analytics 7.4: Administration Guide

Unload, Reload, or Delete a Table

From the main menu in the administrator, select LASRManage Tables.
On the LASR Tables tab, right-click on a table, and select an action.
- If most actions are disabled, select Get Status, and then right-click on the table again.
- To delete or reload a table that is loaded, begin by unloading the table.

Replace a Source Table

To replace a source table, right-click on a LASR table, and select Change Source. You might use the change source action if an original source table is missing, or if you want to add or remove compression for a table.

Note: Not all tables support the change source action.

Note: If the replacement table differs from the original table in a way that affects a permission condition, data access problems can occur. To provide access, remove the permission condition from the LASR table. See Set a Row-Level Permission Condition.

Results

To view a log for the most recent interactive action for a table, open the LASR Tables tab, right-click on the table, and select Last Action Log.

Tip

Not all actions generate a last action log. To determine which action generated a log, examine the log’s task summary and timestamp.

For troubleshooting, see Load, Reload, and Import Issues.

Additional Considerations

Not all tables can be interactively reloaded. See Reload Methods.
Note: When you use the Load a Table action, a job object (named source-table - Load Job date-and-time) is created to support reloading of the table.
- The maximum length for a job name is 60 characters.
- If you edit a job, SAS Visual Analytics might not be able to use the job to perform an interactive reload. In this circumstance, a new job is created the next time you perform a new load of the table.
- To deploy a job for scheduling, see Scheduling in SAS.
The Unload action removes a table from memory, but it does not delete the corresponding metadata object. The Delete action deletes the metadata object that represents an in-memory table.
Most of the tab toolbar buttons affect only tables that have a selected (checked) check box.
Clicking on the cell that is next to a check box toggles the state of that check box. Before you use a tab toolbar button, make sure only the appropriate check boxes are selected. To clear all check boxes, click in the tab toolbar.
To perform an action on multiple tables, select check boxes, and then click an icon in the tab toolbar. To cancel all remaining actions in a multi-table operation, click Cancel in the tab toolbar.
