dbaascli database start

The database start subcommand of the dbaascli utility can be used to start the database instance and open the database.

Execute this command as the oracle user.

dbaascli database start --dbname dbname

In the above command, dbname specifies the name of the database that you want to start.

When this subcommand is executed the database instance is started and the database is opened. In Oracle Database 12c or later, all PDBs are opened.
