Re: [GENERAL] Oracle and Postgresql Play Nice Together on Same Computer?

I guess what I am concerned about *is* running on a production server more
than a test server. Basically, I'd be taking a couple applications that are
running on the Oracle database instance, building a Postgresql instance, and
migrating them to that postgresql database instance. I'm just wondering
whether it's a bad idea to run them on the same server machine in a
production environment. (So instead of having 10 applications running on
Oracle on ServerComputerA...build a new postgresql instance on
ServerComputerA that lives along with Oracle and migrating 3 of the
applications to Postgresql.

Thank you for your time!

For testing purposes there shouldn't be any problems, at least in a
*NIX environment. PostgreSQL is very undemanding and compared to
Oracle is positively minuscule (at least as far as its "installation
footprint" goes). I've run PostgreSQL, MySQL, DB2 and Oracle on the
same development machine without any issues. Of course if another
application is in constant use on a production server PostgreSQL won't
perform as well as it could.
