This can be handled in the TCPIP DATA file itself.  It has support for multiple system IDs (with some rather archaic syntax):

for example, if the System ID of your machine is SYSID1 and the System ID of your DR machine is DRSYS1 then the following would select the appropriate TCPIPUSERID based on the machine:

SYSID1: TCPIPUSERID TCPIP
DRSYS1: TCPIPUSERID TCPDR
