Since you do not have any of the prerequisites this leaves you with some other choices. Since it's for "archival lookup" the easiest would be to create a RHEL Virtual Machine, install Oracle then backup and restore the Database to the newly create RHEL Virtual Machine.
Another option would be to image the HDD to a vHDD by one means or another, e.g. Clonezilla Live or temporarily using the actual physical disk from an external enclosure to temporarily add as a physical disk to then use vmware-vdiskmanager to create a normal file based virtual hard disk to use in the Virtual Machine. Either of these type option will require the hardware be reconfigured in the OS while running in the Virtual Machine and this can be done.
Otherwise, and I haven't tried this although I believe it would work, you could create an ESXi Virtual Machine under VMware Workstation and use that as the required VMware Infrastructure Server although I'd probably opt for just creating a normal RHEL Virtual Machine, install Oracle then backup and restore the Database. That would probably be the easiest and fastest if you'er not comfortable with the other options.
