Getting DB2/AS400 Data to Mysql
db2 / as400 to mysql

 3:19 pm on Mar 29, 2006 (gmt 0)

Lets cut right to the chase…I am trying to collect data from a DB2/AS400 machine and put it into a mysql database. We are then going to display this information to our users on our site that is running the LAMP (linux apache mysql php) configuration. The data housed on the AS400 is behind our corporate firewall, so without a VPN we can not access the data from our site. So I thought I would attempt some type of sync from the AS400 out the firewall to the webserver.

Currently, I using the iseries odbc drive to import the data into mysql and it seems to be taking about two hours to get the data I need. Not at all a good way to show live data.

I am wondering, what is the best way to accomplish the connection?
Is there a better configuration for the iseries driver?
Is there a better driver to use.
What is the best way to give web users live data from a server that is inside a firewall?

If it's behind your firewall you might have trouble doing this, but I was able to bypass mySQL entirely and connect directly to the AS/400 through the ODBC connection.

At one time i even considered using the AS/400 as my DB, given it's incredible stability and security.

As to dump it into mySQL, I don't see a good way to keep the sync close to real time. The iSeries ODBC driver is notoriously slow.

The iSeries ODBC driver is notoriously slow.

Which one? Windows? Because on *nix installations I have successfully implemented iSeries Access for Linux on a few different sites with blazing fast performance. Huge sites too, front and back end (intranet/internet) activity is enormous. I would agree that the iSeries Access for Windows is different though. I've had some success but nowhere near the speeds of the *nix installs.

As far as the entire install goes, why not put the server on the LAN and use your router to allow access to the DMZ host on the http server for the public IP?

I am using the windows iseries driver with a navicat interface to import the data. I do have a few Linux machines and if you say it is fast then I need to look into the iSeries Access for Linux.

As far as putting the machine on the LAN … That is probably not an option at this time plus it is a bit over my head as far as setup. Not that I am not interested in investigating. With our IT, anytime you mix public access with Lan access, they would rather say NO than to invistigate.

If possible, do you have any additional info on the linux version of the iseries?
