migrate from PostgreSQL to Oracle

[jo]

Hi all,

I'm working with same db schema in PostgreSQL and Oracle,
We mainly work in PostgreSQL but sometimes we need to copy schema and data from pg to oracle
because some our customers want to use oracle instead of pg.

Thus I'm looking for some linux script to migrate from pg to oracle.
At the moment, I dump data from pg using pg_dump in the format:
INSERT INTO table (columns) (values)
then I load it into the Oracle db using cx_Oracle
this procedure is so slow, and sometimes I have to edit and modify
data manually, because some INSERT format aren't compatible.
Is there any interesting linux script to do this more easily? something like the ora2pg script.

thanks

Have you tried searching for pg2ora on Google?

Yes Gabriele,
this was the first thing that I did, but I did not find anything
interesting.
Thanks anyway.

If the schemata are truly the same, I'd use 'copy to' a CSV file on the
Postgres side, then SQL*Loader to put it into Oracle. Easily scriptable.

For maximum speed, use 'copy to on the server side; *not* psql, and
(assuming that the data is clean), direct path for SQL*Loader.
