For details check the logfiles at: /opt/oracle/cfgtoollogs/dbca/ORCLCDB. Database Information: Global Database Name:ORCLCDB System Identifier(SID):ORCLCDB Look at the log file "/opt/oracle/cfgtoollogs/dbca/ORCLCDB/ORCLCDB.log" for further details. Database configuration completed successfully. The passwords were auto generated, you must change them by connecting to the database using 'sqlplus / as sysdba' as the oracle user. ``` 配置好后设置当前用户下的环境变量 ``` vi ~/.bashrc (打开文件后追加oracle的环境变量信息) --------------------------------------------------- export ORACLE_HOME=/opt/oracle/product/19c/dbhome_1 export ORACLE_SID=ORCLCDB export PATH=$ORACLE_HOME/bin:$PATH --------------------------------------------------- 通过运行 source ~/.bashrc （命令运行后设置的环境变量生效） ``` **验证安装是否正确** ``` su oracle (用户切换到oracle用户) sysplus / as sysdba SQL*Plus: Release 19.0.0.0.0 - Production on Wed Nov 17 18:59:32 2021 Version 19.3.0.0.0 Copyright (c) 1982, 2019, Oracle.
