ORA-51909

Creating vector index owner_name.index_name is failing because vector indexes that use HAMMING distance can only be created on vectors with INT8 format. Attempted on col_type format.
  • owner_name: The owner of the index.
  • index_name: The index name.
  • col_type: The column type.

Cause

Creating a vector index is failing since vector indexes that use HAMMING distance can only be created on vectors with INT8 format.


Action

Use a distance metric other than HAMMING distance, or ensure all vectors are of INT8 format.
