RE: Mysql to Oracle migration

2005-09-01 Thread Nguyen, Phong

Look at http://www.ispirer.com

It is free and very good tool to do it. I did it from Oracle to MySQL, but
you can do it from Mysql to oracle. Good luck!

You need to talk to Oracle, or look on an Oracle mailing list. People 
here are more concerned about migrating from Oracle to MySQL, rather 
than the other way around.

There are probably lots of commercial tools out there that will do it 
(and compared to your Oracle licensing costs, they are probably 
relatively cheap).

If you got password set for root, try c:\mysql\bin\mysqladmin -u root -p

it should prompt for password.

Shawn Green,
 
You are right? I agree as you said Sure MySQL may have a few fewer bells
and whistles than Oracle but if you don't need to rely on all of the
gee-whiz and just need fast, stable data storage and retrieval, MySQL is an
excellent choice.
 
Thank you for input,
 
Nguyen

Maybe the US Air Force has an unlimited budget but the rest of us do not. It
seems to me that they powers that be in Nguyen's shop have made a decision
(rational or not, you know how some managers are) to move away from a
PREMIUM-priced package like 9i to something that can perform comparably to
9i but at a small fraction of the cost. Calling it an 8th grade toy makes
you sound uninformed of what MySQL is really capable of. 

Sure MySQL may have a few fewer bells and whistles than Oracle but if you
don't need to rely on all of the gee-whiz and just need fast, stable data
storage and retrieval, MySQL is an excellent choice. Besides, most of those
fancy things in the premium databases can be duplicated or nearly
duplicated using very little client-side code. Of the things that cannot be
run in client-side code (I am particularly thinking of stored procedures and
triggers) those are coming in 5.0.x. 

Do you think NASA, Yahoo, and a host of other Fortune 100 companies made a
mistake by using MySQL in their production enviroments? I don't.

It all depends on the application it's used for.

MySQL 5 is a very nice release - once stable, of course - but in some
regards,
it has a long way to go.

No doubt, many Oracle applications can be converted to MySQL, but this
is because those applications don't use Oracle well enough :)

IMO, duplicating something that can, could and should be done on the server
in client code is a step backwards. In earlier days, the foreign key
constraints
like described in the MySQL documentation was a shining example of ignorance
on the part of the documentation writers. Luckily, InnoDB has foreign key
constraints.

But there are plenty of other applications that cannot be converted to
MySQL,
no doubt, some run fine and dandy... We use MySQL here in the office as
well,
but use InterBase and Firebird for others...

The right tool for the job makes the whole difference.
