Re: Why Ruby on Rails is the perfect framework for building next generation Enterprise Apps

Raimonds — Tue, 05 Jun 2007 03:33:47 -0000

For many years I have been managing plenty of Oracle E-Business Suite implementation projects for our customers. And recently I have been studying Ruby on Rails and I am really enjoying it.

So I can compare current PL/SQL and Java technologies in EBS vs RoR and I see that RoR really would be much more productive environment for building enterprise applications.

But so far as I have seen Oracle is building new Fusion applications just on Java technologies and currently I do not see that Oracle is considering using more productive dynamic languages for that.

Do you have any "inside" information if Oracle is considering Ruby or some other dynamic languages for their Fusion applications platform (or at least some part of it)?

It's nice to see that you are successfully running Ruby on Rails application internally at Oracle.

Taking into account growing popularity of Rails inside Oracle it would be good if also you could help with rising priority of porting Oracle Instant Client to Intel Mac. There are so many Rails developers on Macs which feel very frustrated that they cannot develop Rails applications on Oracle database - see OTN discussion thread
http://forums.oracle.com/forums/thread.jspa?thr...

It seems that currently OTN people do not have enough influence on setting priorities for Oracle development.

Re: Sun surprises at RailsConf Europe 2007

I just returned from RailsConf Europe and it was really nice to see that both "big Java companies" Sun and IBM were presented there and are supporting Ruby on Rails.

Unfortunetaly I did not see Oracle there. If Oracle would be there then they would see that 90% of Rubyists use Macs and then they would pay more attention to providing Oracle Instant Client for Intel Mac.

I went to IBM session and it was nice to hear that IBM is developing DB2 Rails adapter by themselves and that they will release DB2 Express-C database on Mac too. I would be very glad if Oracle would do the same as well.

It would be good if you (or somebody :)) could publish some tutorial how to deploy JRuby on Rails application on Oracle Application Server.

Rails mantra is "fat models and skinny controllers" :) In your case controllers seem to be more fat than models. Why is it so?

I wanted to say that my first programming experience in late 80s was on Soviet home computer BK-0010 which also had a tape recorder and which you connected to standard TV set. And you needed to program either in assembler or in FOCAL language. So our beginnings were similar :)

Unfortunately not. This was not our home computer - I went to dad's work at University where I could get to this computer to do some programming couple times per week.

Later my first Unix experience was on Russian clone of PDP-11 minicomputer where my older brother managed to install Russian clone of Unix and I could do my first C programming :) (reading K&R C language book in all capital letters as on Russian printers small Latin letters were replaced with Russian letters)

These olden days were fun - then programming was done just by geeks who really enjoyed it :)

Re: Oracle E-Business Suite Vulnerability: Users Passwords Decrypted

Using Mehmet's Java source as an example I have created
Oracle E-Business Suite authentication plugin in Ruby. You can use this plugin for Ruby on Rails applications that want to use Oracle EBS users and passwords for authentication. Or you can use this as an example how to decrypt Oracle EBS user passwords in Ruby :)

I had a look on the new modified Java class oracle.apps.fnd.security.AolSecurity that this patch delivers.

As Oracle has written in the patch description now user passwords are stored in the following way:
1) at first SHA digest is made from user password
2) and then SHA digest is encrypted with APPS password and stored in encrypted_user_password column

When password verification is done then
1) encrypted_user_password is decrypted with APPS password
2) SHA1 of user password is compared with decrypted result

So it means that it will not be possible to find out all user passwords using APPS password as decryption key.

But as it seems to me if you will have SQL access to the database and if you will have at least one EBS login and password for this database then you will still be able to get APPS password.

"spikes my browser’s memory usage by about 300-500k" - you probably wanted to say 300-500MB? :)
