Limit the number of cells

For performance issues, you can set the maximum number of cells that will be displayed in the Table Explorer view for a database table. Leave this field empty if you want the entire content of the table to be displayed. By default, this field is set to 2000. If a table that has more cells than the value set here is displayed in the Table Explorer view, a warning dialog box will inform you that the table is only partially shown.

Maximum number of children for container nodes

In Oracle XML, a container can hold millions of resources. If the node corresponding to such a container in the Data Source Explorer view would display all the contained resources at the same time, the performance of the view would be very slow. To prevent this, only a limited number of the contained resources is displayed as child nodes of the container node. You can navigate to other contained resources from the same container by using the Up and Down buttons in the Data Source Explorer view. This limited number is set in the field. The default value is 200 nodes.

Show warning when expanding other database schema

Controls if a warning message will be displayed when expanding another database schema and there are tables selected in the current, expanded one. This applies to the Select database table dialog box in the Import Database Data to XML wizard.
