Foundation Pack XREF Migration Utility
By Lionel Dubreuil-Oracle on Feb 16, 2012
The Foundation Pack XREF Migration Utility is a tool to perform a one-time migration of cross reference (XREF) data from the existing single XREF_DATA table to new multi-tables, which may yield performance benefits for customers with large XREF tables.
If you work with large XREF tables, splitting up the single XREF_DATA table into one table per XREF artifact improves cross reference lookup performance. The XREF Migration Utility updates the metadata in the XREF artifacts for this multi-table use case, as well as generates a set of scripts that create a new table for each artifact and migrate the corresponding XREF data to them.
