This may seem as weird question:
If i have user called
demo with password Pass1234
When connecting to oracle 11g I can run
sqlplus like this with password in command line:
on DB host:
C:\> sqlplus demo/Pass1234
Or remote machine
C:\> sqlplus demo/Pass1234@<ip>:1521/orcl
I can do so without give the password in command line and expose it like this:
C:\> sqlplus demo
Then I get:
SQL*Plus: Release 126.96.36.199.0 bla bla bla Copyright (c) bla bla bla Enter password:
Then I can enter the password manually.
When connecting to Oracle 12c I can connect like this from any machine (with password):
C:\> sqlplus demo/Pass1234@<ip>:1521/pdborcl
My question is: How to connect to Oracle 12c without
tnsnames.ora edit and without write the password in the command line?
I also havn't figured out yet if it is possible to connect to Oracle 12c from sqlplus on the DB host machine without give the IP or localhost, and without editing the tnsnames.ora, like I can do in Oracle 11g?
And more thing, can I do so from a remote machine (even to Oracle 11g) without using a full connect?
(means to give user and db connection in command line and password manually, not like use
/NOLOG in command and then:
SQL> connect demo/Pass1234@<ip>:1521/pdborcl)
