Problem: Unable to create or install the Esri spatial type for Oracle (-521)

Solution or Workaround

Find the tables that reference a PUBLIC.ST_GEOMETRY column and drop them.
 

1. Find the tables that reference a PUBLIC.ST_GEOMETRY column.
    

   Code:
   sqlplus sys/manager as sysdba
   
   set pages 9999
   
   SELECT OWNER, NAME, TYPE FROM DBA_DEPENDENCIES WHERE REFERENCED_OWNER='MDSYS' AND REFERENCED_NA
   ME  = 'ST_GEOMETRY' AND REFERENCED_TYPE  = 'TYPE' AND TYPE='TABLE';
   
   OWNER                       NAME                           TYPE
   --------------------------- ------------------------------ ------------------
   MAP                         TEST                           TABLE
   

2. Drop the table found in Step 1. 
    

   Note:
   If the table is needed for any reason, backup the table before dropping it. This table can be restored after Esri ST_Geometry is installed.

    

   Code:
   drop table map.test;
   

3. Purge the recycle bin.
    

   Code:
   purge dba_recyclebin;

4. Re-run the install of the Esri ST_Geometry type

 

 

SELECT OWNER, NAME, TYPE FROM DBA_DEPENDENCIES WHERE REFERENCED_OWNER='MDSYS' AND REFERENCED_NAME  = 'ST_GEOMETRY' AND REFERENCED_TYPE  = 'TYPE' AND TYPE='TABLE';
