登录数据库
sqlplus / as sysdba
创建参数文件
create spfile from pfile=’/u01/app/oracle/product/19.0.0/dbhome_1/dbs/initnewcdb.ora’;
启动实例
;startup nomount;
使用CREATE DATABASE语句创建新的CDB
set echo on
set timing on
@/home/oracle/bin/create_db_newcdb.sql
数据库是否为CDB
SELECT dbid, name, created, log_mode, open_mode, cdb, con_id FROM v$database;
种子数据库
col name for a8
SELECT con_id, dbid, name, open_mode, restricted, TO_CHAR(open_time, ‘DD-MON-YY HH:MI:SS AM’) OPEN_TIME FROM v$containers;
查询CDB / PDB名称，表空间名称，数据文件位置，大小和状态
col db_name for a8

运行下个面4个脚本
catalog.sql创建数据字典表的视图，动态性能视图以及许多视图的公共同义词
catproc.sql运行PL / SQL所需或与PL / SQL一起使用的所有脚本
pupbld.sql: 对于SQL * Plus是必需的。启用SQL * Plus以禁用用户命令。
utlrp.sql：重新编译处于无效状态的所有PL / SQL模块，包括程序包，过程和类型。
