Le 20/08/2020 à 16:30, Ko, Christina a écrit :
Hi All,
I am running into issue using DMS to load oracle spatial data
(oracle 11.2.0.3) to postgresql.
Oracle table:
CREATETABLESpatial_Tbl
IDNUMBER(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.

Well if you start with Ora2Pg your bible is
http://www.ora2pg.com/documentation.html and especially this chapter
that will make you save time
http://www.ora2pg.com/documentation.html#Generate-a-migration-template
After reading that as a shortcut once your ora2pg.conf is configured to
communicate with Oracle and if you just want to migrate this single table:
ora2pg -c config/ora2pg.conf -t COPY -b data/ -o data.sql -a
'SPATIAL_TB1'
I also recommend you to read
http://www.darold.net/confs/ora2pg_the_hard_way.pdf, it is a bit old but
plenty of useful information on Ora2PG use.
Best regards,
