Oracle Spatial Point Cloud Reader Parameters

This parameter specifies a database connection for the reader through a drop-down menu. The Add Database Connection option in the menu allows for a new connection to be created. The new connection can be made visible only to the current user, or can be shared among multiple users.

Specifies the Oracle database to connect to. This may be a Net Service Name defined in tnsnames.ora or an Easy Connection Identifier. Either form of connection identifier may be prefixed with username and password information.

[<username>[/<password>]@][//]<hostname>[:<port>]/<service_name>.

[<username>[/<password>]@]<net_service_name>

The username and password.

The name of the Oracle Workspace Manager workspace that will be used by the reader. All tables will be read using the same workspace. If this parameter is omitted, or left blank, the default LIVE workspace will be used.

If this parameter is selected (default), the Oracle database connection remains open for other requestors. A persistent connection is useful for workspaces that are long-running, or published using FME Server.

If this parameter is deselected, the connection to the Oracle database is closed as soon as possible after data processing is complete.

Specifies whether to keep the schema qualifier. The full name of a table in an Oracle database is of the format <owner_name>.<table_name>. Selecting this parameter indicates that the reader should return the table name without any prefixes. This is useful, for example, when creating a workspace that will be passed on to another organization using the same table names.

When this parameter is selected during the generation of a workspace, the source feature types will be the table names without any prefix; otherwise, they will contain the owner name as a prefix. It is recommended that you do not change this parameter after generating the workspace, because it is possible for no features to be successfully passed onto the writer (since the writer is expecting feature types with different names).

Note: Note: Even when this parameter is selected, if the table is owned by a user other than the current user, the <owner_name> prefix will not be dropped. This is to ensure that the reader will find the correct table.

After you have completely specified the database connection, click the Browse button to select tables for import. A connection window appears while the system compiles a table from the database.

Once the table list appears, you can select one or more tables, and then click OK to dismiss the window. The table name(s) will appear in the table list field in the Reader Parameters box.

Enter any SQL where clause that constrains the attributes of the layers selected in the layer list (for example, NUMLANES=2).

Use this matrix to map Oracle database dimensions to FME point cloud components. Each FME component that is mapped will appear in the point cloud geometry.

Use this parameter to expose Format Attributes in Workbench when you create a workspace:

• In a dynamic scenario, it means these attributes can be passed to the output dataset at runtime.
• In a non-dynamic scenario where you have multiple feature types, it is convenient to expose additional attributes from one parameter. For example, if you have ten feature types and want to expose the same attribute in each one, it is easier to define it once than it is to set each feature type individually in the workspace.

Using the minimum and maximum x and y parameters, define a bounding box that will be used to filter the input features. Only features that intersect with the bounding box are returned.

If all four coordinates of the search envelope are specified as 0, the search envelope will be disabled.

Select this parameter to remove any portions of exported features outside the area of interest.

The illustration below shows the results of the Search Envelope when Clip to Search Envelope is set to No on the left side and Yes on the right side.

• No: Any features that cross the search envelope boundary will be read, including the portion that lies outside of the boundary.
• Yes: Any features that cross the search envelope boundary will be clipped at the boundary, and only the portion that lies inside the boundary will be read. The underlying function for the Clip to Search Envelope function is an intersection; however, when Clip to Search Envelope is set to Yes, a clip is also performed in addition to the intersection.

Specifies the coordinate system of the search envelope if it is different than the coordinate system of the data. The coordinate system associated with the data to be read must always be set if this parameter is set.

If this parameter is set, the minimum and maximum points of the search envelope are reprojected from the Search Envelope Coordinate System to the reader’s coordinate system prior to applying the envelope.

Rows are read from the Oracle database using a bulk reading technique to maximize performance.

This parameter allows you to tune the performance of the reader by specifying how many rows are read from the database at a time.

Specifies the minimum resolution level of block data that will be read. Usually, lower values mean farther from the view point and higher values mean closer to the view point.

If neither minimum nor maximum resolution levels are specified, all block data will be read.

Specifies the maximum resolution level of block data that will be read. Usually, lower values mean farther from the view point and higher values mean closer to the view point.

If neither minimum nor maximum resolution levels are specified, all block data will be read.
