I have the task of finding out on Windows if you can have a 64 bit installation and 32 bit installation of the Oracle client libraries installed at the same time (I am using Oracle 11g client libraries). The 32 bit application runs as a service, and I don't know about the 64 bit application yet. Is this possible as they both need a different ORACLE_HOME variable? If the 32 bit application ran in the foreground I would just use a batch file to set the variable, but I don't know how to set the environment for a service.
Is there an Oracle solution for this? Or is this a windows thing?
