The clients connect via sqlnet to a remote database server, but we have 2 entries for IPC connections in the listener.ora:
(ADDRESS = (PROTOCOL = IPC)(KEY = oracle.world))
(ADDRESS = (PROTOCOL = IPC)(KEY = ORCL))
We also have automatic_ipc=off in the sqlnet.ora on the server and on all the client's. Can I remove the IPC entries in the listener.ora? Or should I set up IPC for any local connections (if any)?
