I have an Oracle V6 and an Oracle7 server running concurrently on my Sun SS1+ without problems. Setting the appropriate ORACLE_SID I can connect to the one or the other and setting the TWO_TASK env variable I can also connect to a remote database. Watch out for the amount of semaphores and shared memory allocation under SunOs 4.1.3.
