Hi All,

I am running into issue using DMS to load oracle spatial data (oracle 11.2.0.3) to postgresql.

Oracle table:

CREATE TABLE Spatial_Tbl
ID NUMBER(38,9),
P_ID NUMBER(38,9),
GEOMETRY MDSYS.SDO_GEOMETRY

AWS DMS calls the SDO2GEOJSON custom function trying to load the data, but it failed and the Geometry columns in Postgresql was empty

I also tried using SDO_UTIL.TO_GEOJSON utility and didn't work either.

I am looking for suggestions of how to load the geometry data from oracle 11.2.0.3 to oracle.

Thanks in advanced for your help!

Hi,

You can either use oracle_fdw or Ora2Pg. The first is a FDW extension that will allow you to use a foreign table to upload the data into your destination table and the second tool export data from the Oracle database to plain text file or to your PostgreSQL table directly.

Best regards,

I have just installed ora2pg and will see if it works. I believe I have to specify my setting in the config, do you have any suggestion of what I have to set in the config file to load spatial data from oracle to postgresql. Thank you.
