[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

解决:

[3.4.3 Starting EM Express for a PDB](http://docs.oracle.com/database/122/ADMQS/getting-started-with-database-administration.htm#ADMQS12485)

Connect to the CDB$ROOT container for the CDB that includes the PDB, and issue the following SQL statement to configure the global port for the CDB:

exec dbms_xdb_config.setglobalportenabled(TRUE);

SQL> SELECT 'https://'||SYS_CONTEXT('USERENV','SERVER_HOST')||'.'||SYS_CONTEXT('USERENV','DB_DOMAIN')||':'||dbms_xdb_config.gethttpsport()||'/em/' from dual;

'HTTPS://'||SYS_CONTEXT('USERENV','SERVER_HOST')||'.'||SYS_CONTEXT('USERENV','DB

https://databasevm.:5500/em/

SQL> exec dbms_xdb_config.setglobalportenabled(TRUE);
