I used the migration assistant to move a 7.3.4 database to 8.1.6. This was succesfull.

Later I deinstalled the 7.3.4 server and removed all the binaries including SQL*Net since I already had Net8 installed as part of the migration.

After this when I try to startup, it comes back with a
"TNS Protocol Error"

Can somebody help please.

Thanks,
