ORA-29855: error occurred in the execution of ODCIINDEXCREATE routine

Error Message

When attempting to create a spatial index on a st_geometry attribute with SQL, the command fails with the following Oracle error:"ORA-29855 error occurred in the execution of ODCIINDEXCREATE routine".

Cause

In this specific case, the Oracle error ORA-29855 is being encountered because the parameters string clause contains an unnecessary comma between the st_srid and st_grids parameters.

Code:
SQL> CREATE INDEX shp_idx_1k ON st_relation_perf (shape) INDEXTYPE IS sde.st_spatial_index
  2  parameters('st_srid=12, st_grids=25000');
CREATE INDEX shp_idx_1k ON st_relation_perf (shape) INDEXTYPE IS sde.st_spatial_index

Solution or Workaround

• The correct syntax for creating the index is the following:
  
  

  Code:
  SQL> CREATE INDEX shp_idx_1k ON st_relation_perf (shape) INDEXTYPE IS sde.st_spatial_index
    2  parameters('st_srid=12 st_grids=25000');

  
  
• When creating a spatial index do not insert any commas between the arguments in the parameters clause.
