Installing Oracle Service Bus on 64-bit Ubuntu 11.04
By Jeff Davies-Oracle on Aug 15, 2011
Sample Project: The File Protocol
I'm working on some more sample code for the Oracle Service Bus. The samples are available for download at http://soasamples.samplecode.oracle.com. I don't have the finished files posted there yet, but if you want to see the sample / tutorial in web video form, head on over to http://jeffdavies.org and check out the File Handling tutorial there. It covers a very common use case where OSB picks up a flat file from a directory (often created by a legacy system), converts the flat file into multiple XML files for individual processing. Its a common pattern for integrating batch systems into an SOA.
Installing OSB on 64-bit Ubuntu
I recently upgraded my laptop from 32-bit Ubuntu 10.04 to 64-bit 11.04. While reinstalling Oracle Service Bus (OSB) from the ofm_osb_generic_18.104.22.168.0_disk1_1of1.zip file, I got the following error message (after I invoked the runInstaller script and provided a path to my JDK):

There is a dependency on a 32 bit library. Fortunately, the solution for this was pretty simple. I needed to do 2 things to get the installer to work:
1) Install the 32-bit compatibility library using tyhe following command:
sudo apt-get install ia32-libs
2) Start the install script using the linux32 emulation utility. The command is as follows:
After that, the installation process proceeds normally.
