Oracle OCP笔记(05)企业管理器(EM)1.企业管理器Enterprise Manager Database Control(Oracle 11g)
emctl status dbconsole
emctl start dbconsole
emctl stop dbconsole
使用浏览器连接到Database Control，注意打开防火墙端口，默认端口是1158。
https://hostname:port/em
2.企业管理器Enterprise Manager Database Express(Oracle 12c)
使用EM Express:
打开em:
exec dbms_xdb_config.sethttpsport(5500); -- https
exec dbms_xdb_config.sethttpport(5505); -- http
关闭em:
exec dbms_xdb_config.sethttpsport(0); -- https
exec dbms_xdb_config.sethttpport(0); -- http
查看em端口:
select dbms_xdb_config.gethttpsport from dual;-- https
select dbms_xdb_config.gethttpport from dual; -- http
使用浏览器连接到Database Express:
https://hostname:port/em
浏览器应该使用支持html5的高版本的浏览器，如Google Chrome，低版本IE,Firefox似乎不能连接。
3.手动配置Enterprise Manager Database Express端口(Oracle 12c)
如果用dbca创建数据库时没有选择或配置Enterprise Manager Database Express，则需要手动配置EM Express.
·注册监听器
如果监听器listener运行在非标准端口(1521)，则初始化参数local_listener需注册正确的监听:
select value from v$parameter where name = 'local_listener'; -- LISTENER_SID，名称在tnsnames.ora中配置
alter system set local_listener=inst1;
tnsnames.ora:
inst1= (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=host_name)(PORT=1234))
(CONNECT_DATA=(SERVICE_NAME=service_name)(SERVER=DEDICATED)))
·配置dispatchers
修改初始化参数dispatchers
select value from v$parameter where name = 'dispatchers';
alter system set dispatchers='(PROTOCOL=TCP) (SERVICE=<sid>XDB)';
alter system set dispatchers='(PROTOCOL=TCP) (SERVICE=salesXDB)';
·设置EM Express访问端口
non-CDB:
exec dbms_xdb_config.sethttpsport(5500);
CDB:
alter session set container=CDB$ROOT;
exec dbms_xdb_config.sethttpsport(5501);
PDB:
alter session set container=PDB1;
exec dbms_xdb_config.sethttpsport(5502);
·确认端口是否已注册到监听器
$ lsnrctl status | grep -i 5500
·使用EM Express(non-CDB,CDB,PDB):
https://database-hostname:portnumber/em/
