[原创]DB12cR2_Express设置
从12c开始，DB control已经被Express替换。
EM express是一个非常简化版本Database control，仅提供最基本的数据库管理和性能监控管理。
例如如果你想做备份恢复，你只能通过cloud control（EMCC）来做，通过EM Express你可以view数据库的基本参数信息，存储信息，添加数据数据文件，表空间，用户管理等。
Express更加轻量，使用情况看下图汇总。
注意：
EM Express使用Shockwave Flash文件，所以浏览器必须安装flash插件，同时在你访问EM Express的时候监听必须是启动的。
特别注意：要访问的地址的操作系统防火墙是否关闭，或将访问端口添加到防火墙允许访问端口。
启动步骤
参考：
To manually configure the HTTP/HTTPS port for EM Express:
1- If the listener is running on a nonstandard port (for example, not 1521), then the init.ora file for the database you want to manage using EM Express must contain a local_listener entry so that the HTTP/HTTPS port can register with the correct listener. The local_listener entry references a TNSNAMES entry that points to the correct listener. For example:
local_listener=inst1
where inst1 is a TNSNAMES entry defined in tnsnames.ora that points to the listener. For example:
inst1= (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=host_name)(PORT=1234))
(CONNECT_DATA=(SERVICE_NAME=service_name)(SERVER=DEDICATED)))
2- Enable the TCP dispatcher by adding the following entry to the init.ora file for the database you want to manage using EM Express:
dispatchers="(PROTOCOL=TCP)(SERVICE=<sid>XDB)"
For example, if the database SID is ORCL, then the entry would be:
dispatchers="(PROTOCOL=TCP)(SERVICE=ORCLXDB)"
3- Use the PL/SQL procedure DBMS_XDB_CONFIG.SETHTTPSPORT to set the HTTPS port for EM Express. This will update the HTTPS port in the xdbconfig.xml file in the Oracle XML DB Repository. You must connect as SYS / AS SYSDBA to run the procedure. For example:
SQL> connect sys/<password>@<container> as sysdba
SQL> exec DBMS_XDB_CONFIG.SETHTTPSPORT(5500);
or use the PL/SQL procedure DBMS_XDB_CONFIG.SETHTTPPORT to set the HTTP port for EM Express. This will update the HTTPS port in the xdbconfig.xml file in the Oracle XML DB Repository. You must connect as SYS / AS SYSDBA to run the procedure. For example:
SQL> connect sys/<password>@<container> as sysdba
SQL> exec DBMS_XDB_CONFIG.SETHTTPPORT(2200);
监听和TNS等已经配置好，启动配置端口即可
