2.3 创建ora21c数据库及创建ora21cpdb

2.3.1 拷贝配置文件

cp /etc/init.d/oracledb_ORCLCDB-21c /etc/init.d/oracledb_ora21c-21c
cp /etc/sysconfig/oracledb_ORCLCDB-21c.conf /etc/sysconfig/oracledb_ora21c-21c.conf

2.3.2 修改配置文件

vi /etc/init.d/oracledb_ora21c-21c

# DB defaults
export ORACLE_HOME=/opt/oracle/product/21c/dbhome_1
export ORACLE_SID=ora21c
export TEMPLATE_NAME=General_Purpose.dbc
export CHARSET=AL32UTF8
export PDB_NAME=ora21cpdb
export LISTENER_NAME=LISTENER
export NUMBER_OF_PDBS=1
export CREATE_AS_CDB=true

2.3.3 创建数据库

/etc/init.d/oracledb_ora21c-21c configure

2.4 配置环境变量

vi  /home/oracle/.bash_profile

export ORACLE_HOME=/opt/oracle/product/21c/dbhome_1
export PATH=$PATH:/opt/oracle/product/21c/dbhome_1/bin
export ORACLE_SID=ora21c
