          今天打算啟用一下Oracle Database 11g的Database Control,發現初始并未安裝:

          [oracle@test126 ~]$ emctl start
          EM Configuration issue. /opt/oracle/product/11.1.0/test126.hurray.com.cn_dodd not found.

           

          遇到這類問題,可以通過重新配置,來創建EM的配置文件:

          [oracle@test126 11.1.0]$ emca -config dbcontrol db -repos recreate

          Oracle 10g中,配置方法與此相同。
          配置完成之后就可以啟動EM了:

          [oracle@test126 11.1.0]$ emctl start dbconsole
          Oracle Enterprise Manager 11g Database Control Release 11.1.0.6.0

          如果是Linux環境,你可能還需要在iptables中開放1158端口,增加如下一行:
          -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 1158 -j ACCEPT

          重新啟動防火墻之后就可以通過IE在遠端連接EM的Database Control了:

          [root@test126 sysconfig]# service iptables restart
          Flushing firewall rules: [ OK ]
          Setting chains to policy ACCEPT: filter [ OK ]
          Unloading iptables modules: [ OK ]
          Applying iptables firewall rules: [ OK ]
          Loading additional iptables modules: ip_conntrack_netbios_ns [ OK ]

           


          -The End-

               摘要: 簡單來說序列化就是一種用來處理對象流的機制,所謂對象流也就是將對象的內容進行流化,流的概念這里不用多說(就是I/O),我們可以對流化后的對象進行讀寫操作,也可將流化后的對象傳輸于網絡之間(注:要想將對象傳輸于網絡必須進行流化)!在對對象流進行讀寫操作時會引發一些問題,而序列化機制正是用來解決這些問題的!

               摘要: 大家都清楚在用PowerDesigner的時候,當你輸入Name的時候Code是會自動幫你按照Name的內容填上的.

          這個功能雖然好用,但是我需要在Name這一項加上一個中文的注釋,這個時候怎么辦呢?

          下面兩個例子,相信對你相當有用.  閱讀全文
