How to use sqlplus to connect to an Oracle Database located on another host without modifying the own tnsnames.ora

oraclesqlplus

I want to connect to an oracle database located on another host using sqlplus. This page suggested adding an item on my tnsnames to conenct to that database

local_SID =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL= TCP)(Host= hostname.network)(Port= 1521))
    (CONNECT_DATA = (SID = remote_SID))
  )

and then use that in sqlplus

sqlplus user/pass@local_SID

However, in my circumstances modifying the local tnsnames is not possible. Is it possible to connect to a remote database just by using sqlplus argument without having to change tnsnames? Something like

sqlplus user/pass@remote_SID@hostname.network ;( I know, this one is not valid)

Best Answer

 sqlplus user/pass@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(Host=hostname.network)(Port=1521))(CONNECT_DATA=(SID=remote_SID)))

Maybe, and this might be dependant on the command line environment you're using, you need to quote the string, something like 

 sqlplus "user/pass@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(Host=hostname.network)(Port=1521))(CONNECT_DATA=(SID=remote_SID)))"

or

 sqlplus 'user/pass@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(Host=hostname.network)(Port=1521))(CONNECT_DATA=(SID=remote_SID)))'
