There is an Oracle Real Application cluster in place and the Oracle database is a container database. Due to this, the connection failed. To enable the System Identifier SID in the connect descriptor to be interpreted as a service name when a user attempts a database connection. Database clients with earlier releases of Oracle Database that have hard-coded connect descriptors can use this parameter to connect to a container or pluggable database. When the database is an Oracle Database 12c container database, the client must specify a service name to connect to it.

Setting this parameter to on instructs the listener to use the SID in the connect descriptor as a service name and connect the client to the specified database. The parameter is used for connecting directly through local listeners. Asked 4 years, 6 months ago. Active 4 years, 6 months ago. Viewed 1k times. Error java. Community Bot 1 1 1 silver badge.
