Problem: When I overwrite an existing shapefile with an older version, ArcIMS does not update the index files

Description

When I overwrite an existing shapefile with an older version, ArcIMS does not update the index files.

Cause

In ArcIMS, index files are:

1. Created if a shapefile does not have the corresponding index files.

2. Updated if the new shapefile has a date and time stamp that is younger than the index files.

Solution or Workaround

When an existing shapefile is overwritten with an older shapefile, neither of the above conditions apply. To synchronize the index files with the older shapefile do one of the following:

  • Delete the existing index files and ArcIMS will automatically reindex the shapefile.
  • Update the existing index files by copying in the older index files.
