IBM WebSphere Application Server - Support for 32-bit and 64-bit application servers
This goes into the "I did not know that" category ….
IBM WebSphere Application Server supports both 32-bit and 64-bit application servers in the same cluster that are managed by either a 32-bit or 64-bit deployment manager. This scenario applies to both 32-bit and 64-bit versions of WebSphere Application Server on 64-bit operating system kernels and to 32-bit versions of WebSphere Application Server on 32-bit operating system kernels.
It is recommended that you confirm that you are using the latest service levels of the operating system and WebSphere Application Server when you are using both 32-bit and 64-bit application servers in your environment.
