Starting the Oracle service manually

Start the listener control utility.

cd $ORACLE_HOME/bin
./lsnrctl start

Verify that the listener control utility is started.

./lsnrctl service

Start the Oracle database.

cd $ORACLE_HOME/bin
./sqlplus sys/iMC123 as sysdba
SQL>startup
SQL>exit

Start the pluggable database. This step is required if the Oracle database is a container database.

cd $ORACLE_HOME/bin
./sqlplus sys/iMC123@PDBORCL as sysdba
SQL>startup
SQL>exit

In the commands, PDBORCL is the network service name of the pluggable database.
