Ubuntu上启用X11VNC  并使用web访问VNC   计算中心节点，没有远程控制不能活，就得装个VNC。 启动Ubuntu的软件中心，选择“X11VNC服务器”，进行安装。当然也可以用sudo apt-get install命令安装。 接下来创建登陆密码sudo x11vnc -storepasswd 输入和确认之后，密码被保存到了用户的密码目录下：  再设置X11VNC的密码文件：sudo x11vnc -storepasswd in /etc/x11vnc.pass 将密码文件复制过去：sudo cp /root/.vnc/passwd /etc/x11vnc.pass打开/etc/init/x11vnc.conf文件，粘贴以下内容。如果没有这个文件，就用文本工具创建一个。端口:5900，自己可以定义。要打开web 访问VNC，并加参数： -shared  -httpstart on login-session-start script x11vnc -display :0 -auth /var/run/lightdm/root/:0 -forever -bg -o /var/log/x11vnc.log -rfbauth /etc/x11vnc.pass -rfbport 5900 -shared -http end script   保存后重启Ubuntu。 在别的操作系统里启动VNC Viewer，这里用的是Windows 7下安装的Real VN...

Automating Database Startup and Shutdown on LinuxIf you are using Oracle Clusterware 10gR2 or above for RAC or just for a single instance using ASM, the Clusterware automatically starts and stops the Oracle database instances and listeners, so the following procedures are not necessary. Where the Clusterware is not being used, these methods allow you to automate the startup and shutdown of databases on Linux.The "su" CommandThe "rsh" CommandKnown IssuesOracle 11gR2+ UpdateNote. These methods work on all RHEL and Oracle Linux versions.The "su" CommandThe following represents the Oracle recommended method for automating database startup and shutdown of Oracle 9i instances on Linux, but it works equally well for Oracle 10g, 11G and 12c also. It can be used on any RHEL-style distribution, including Oracle Linux, up to an including RHEL6.Once the instance is created, edit the "/etc/oratab" file setting the restart flag for each instance to 'Y'.TSH1:/...

On Linux, ASM is capable of referencing disks as raw devices or by using the ASMLib software. This article presents the setup details for using either raw devices or ASMLib, as well as the procedures for converting between both methods.The article assumes the operating system installation is complete, along with an Oracle so...
