配置访问CDB和PDB的OEM

检查数据库是否为多租户容器数据库。
select name, cdb, con_id from v$database;

检查实例名称

select instance_name, status, con_id from v$instance;

返回为EM Express配置的端口。
select dbms_xdb_config.gethttpsport() from dual;

显示PDB

select con_id, name, open_mode from v$pdbs;

ALTER SESSION SET CONTAINER=pdb4;

SELECT dbms_xdb_config.gethttpsport() from dual;

通过执行lsnrctl status 命令来验证侦听器已启动
lsnrctl status

验证 初始化参数文件中的DISPATCHERS参数是否包含PROTOCOL = TCP 属性。
show parameter dispatchers

alter session set container=CDB$ROOT;

DBMS_XDB_CONFIG.SETHTTPSPORT 过程以为CDB的EM Express设置HTTPS端口
exec DBMS_XDB_CONFIG.SETHTTPSPORT(5501);

alter session set container=pdb4;

exec DBMS_XDB_CONFIG.SETHTTPSPORT(5502);
