Specifying connect strings
If an SQL*Net host connection string is specified, the connection is established through SQL*Net. If no connection string is specified, a direct connection is established to the database identified by the current ORACLE_SID environment setting.
For example, specifying
- UserID
- Scott
- Connect String
- remote_db
results in connecting with the connection string `Scott@remote_db'.
Note: A connection string
is always required when connecting to a remote database. For more information
about the syntax of the connection string, see your Oracle documentation.
