Can I install both 32bit and 64bit versions of the Oracle 11gR2 database server on the same Linux se

I've been asked to install a 32 bit oracle database onto a 64 bit Linux server that already contains a 64 bit Oracle database server installation.

Can anyone point me to any information on how this can be done?

I've been asked to do it so it can be used to test a process for importing data from a 32 bit Oracle database onto another in a system that uses a 64 bit Oracle database. Both systems use Oracle 11gR2 as the database. However in the test environment we only have one Linux server available to try and replicate this hence I've been asked to build both on the same 64 bit server.
