Обсуждение: Porting Web application written in Oracle 8 PL/SQL to Postgresql

Hi all,

My company has a pretty big Web-based application written in PL/SQL
using an Oracle 8 backend database. We're thinking about moving from
Oracle to Postgresql. I wondered if there's any quick way to do the
porting:

- Any auomated tools to translate the PL/SQL code & to create tables?
- What process do you recommend for doing the porting?
- Other suggestions?

Thanks a lot.

Andy

Look at http://www.openacs.org in openacs4 comunity.

Not a quick way. But there's a way :)

As Domingo suggested, http://openacs.org/ is a pretty big web application
framework and applications built for Oracle and PostgreSQL. You can find
ideas in its data model of how to cope with the differences. It has
hundreds of PL/SQL (and PL/pgSQL) functions, and it's GPL'd.

The Porting Guide that Josh suggested is also included in the PostgreSQL
documentation, in the Programmer's Guide.
