One point to remember - configure your listener for remote (or 127.0.0.1 loopback) startup/shutdown if you are not using thick/bequeath Oracle client 'C' code, so the listener can find the database when the database is down.

listener.ora entry:

SID_LIST_LISTENER =
 (SID_LIST=
  (SID_DESC=
   (GLOBAL_DBNAME=THEDATABASE)
   (ORACLE_HOME=THE_ORACLE_HOME)
   (SID_NAME=THEDATABASE)
  )
 )

Should even work from a Mac - pure Java..

NET Command - persistently store network details with tab completion

Example using tab completion: (need to be in sql for tab complete to work e.g. ./sql /nolog)

SQL> net unique=localhost:1521/mysid;
SQL> net list
unique
SQL> net list unique
unique
------
localhost:1521/mysid
SQL> connect username/password@uni__TAB_FOR_COMPLETION__
SQL> connect username/password@unique

tab completion works for net shortcuts and tnsnames.ora details.

Behind the scenes net is very similar to the alias command.

NET
------

Command line only - not for sqldeveloper.

NET is a command which allows you to save a network details and assign it a shortcut command.
"net" - print a list of net short cuts
"net list " - list the contents of the short cut
"net name=localhost:1521/XE;" simple net command
"net drop name" - delete the short cut called name

net is single line terminated by newline
net ..=.. is terminated by ';'
net on its own gives a list of existing short cuts.

controlled by
set net on|off|readonly - default ON
   readonly means only do try to enter a net shortcut on successful connect command
set noverwrite on|off|warn - default WARN
   net overwrite: warn prints a warning if an override would otherwise happen.
