New and Changed LRS Subprograms
The new SDO_LRS.FIND_OFFSET function returns the signed offset (shortest
distance) between a point and a geometric segment.
The SDO_LRS.PROJECT_PT function includes a new optional output parameter
offset, which stores the signed offset of the projected point from the geometric
segment.
See Chapter 16 for reference information about linear referencing system (LRS)
subprograms.
Tolerance with LRS Subprograms
In the current version of this guide, tolerance is shown as a required parameter
for many LRS subprograms where it had previously been shown as optional.
Applications that used tolerance as an optional parameter in such cases will
continue to work in this release; however, such usage is deprecated and will not be
supported in future releases. If you use an LRS subprogram format in which
tolerance is shown as required, you should specify that parameter.
See also Section 7.6, which contains new information about tolerance values with
LRS subprograms.
New Tuning Function: ESTIMATE_RTREE_INDEX_SIZE
The new SDO_TUNE.ESTIMATE_RTREE_INDEX_SIZE function, described in
Chapter 18, estimates the maximum number of megabytes needed for an R-tree
spatial index table.
Deprecated Tuning Subprograms
The following SDO_TUNE subprograms specific to spatial quadtree indexing are
deprecated:
■ SDO_TUNE.ESTIMATE_INDEX_PERFORMANCE
■ SDO_TUNE.ESTIMATE_TILING_LEVEL
■ SDO_TUNE.ESTIMATE_TILING_TIME
■ SDO_TUNE.ESTIMATE_TOTAL_NUMTILES
■ SDO_TUNE.HISTOGRAM_ANALYSIS
