How do I use sqlplus connect string?
Let's say I have an Oracle database. I have a username = x, password = y, database = z. Also I know the port = a, SID = b, Hostname = c.
So how do I need to connect correctly? I used many options like:
sqlplus x/y@'(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=c)(PORT=a))(CONNECT_DATA=(SID=z)(SERVER=DEDICATED)))'
sqlplus (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=c)(PORT=a))(CONNECT_DATA=(SID=b)))
Submitting these command lines usually gives me back error messages like:
ORA-12560: TNS:protocol adapter error
ORA-12514: TNS:listener does not currently know of service
For sqlplus connect string, you should try:
sqlplus username/password@host:port/service
sqlplus x/y@c:a/b
modern versions of sqlplus (version 11 or newer) understand this syntax and you don't need a tnsnames.ora file.
