首先，通過telnet遠(yuǎn)程登錄到linux服務(wù)器，然后啟動sqlplus，這樣你就可以完成大部分的DML操作了。1. 啟動sqlplus：登錄成功后，在終端提示符下輸入sqlplus命令，如下所示： ``` [oracle@graduate ~]$ sqlplus SQL*Plus: Release 11.2.0.1.0 Production on Sun Nov 17 16:20:12 2013 Copyright (c) 1982, 2009, Oracle. All rights reserved. Enter user-name: system Enter password: Connected to: Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - Production With the Partitioning, OLAP, Data Mining and Real Application Testing options SQL> ```2. 啟動EM（Enterprise Manager）：在終端提示符下輸入以下命令來啟動數(shù)據(jù)庫控制臺： ``` [oracle@graduate ~]$ emctl start dbconsole Oracle Enterprise Manager 11g Database Control Release 11.2.0.1.0 Copyright (c) 1996, 2009 Oracle Corporation. All rights reserved. https://localhost:1158/em/console/about Application Starting Oracle Enterprise Manager 11g Database Control . started. ------------------------------------------------------------------ Logs are generated in directory /home/oracle/app/oracle/product/11.2.0/dbhome_1/localhost_test/sysman/log ```以上步驟描述了如何在Linux環(huán)境下啟動Oracle 11g的企業(yè)管理器（EM）和SQL*Plus。
