Descripción

This Patch is now obsolete. It has been superceded by the ArcGIS 9.1 Service Pack 1.

Issues Addressed with this Patch


  • The main issues addressed with this Patch are:

    • Fixes an issue with the Route solver where the sequencing optimization, find best sequence option, is always based on the first selected impedance.
    • Reduces the memory consumption of the Route solver.
    • Corrects two errors related to the Closest Facility solver; one fixing a fatal error occurring when the geometry for a large number of routes is generated, and one other improving the solution quality, closer facilities found, when using the hierarchy option.
    • Corrects an issue where a barrier may not be avoided when solving on SDC network datasets.
  • CQ00247269 - Reduce the memory consumption for the Route solver.

    CQ00264540 - The Closest Facility solver crashes when solving a large problem requiring to generate the geometry of all computed routes.

    CQ00265678 - The Closest Facility solver may occasionally miss closer facility(ies) when the hierarchy option is used.

    CQ00272292 - Each Route solve is based on the first impedance attribute used when the Find Best Sequence option is used.

    CQ00273289 - Barriers may not be avoided when placed on major roads of an SDC network dataset.

    How to identify which Patch is installed

    To check for the presence of a Patch, for each file examine the unique identification information provided (right click, properties, version tab, item name, QFE Version). With only a few exceptions, all files modified as part of a Patch distribution can be uniquely identified in this manner. The identification string for this Patch should read:

    • QFE-DT-91-CQ00272894
