日前在2009甲骨文全球大会上,甲骨文公司宣布最新版Oracle服务器虚拟化软件Oracle? VM 2.2正式上市,现在客户可以加速部署并简化企业应用的管理,以最环保和最高效的方式运行数据中心,同时降低成本。
Oracle VM 2.2具有基于Xen的最新业界标准管理程序Xen 3.4,可使运行在基于英特尔微型架构的英特尔至强5500系列处理器(代码名为Nehalem)以及6核AMD皓龙处理器的客户系统大幅提高性能。
Oracle VM 2.2具有新的CPU电源管理、内存管理和直接磁盘I/O功能。
此外,这一版还实现了Oracle VM与Virtual Iron技术的首次集成,从而使客户能够非常容易地将Virtual Iron虚拟机迁移到Oracle VM图像上。
Oracle VM支持Oracle和非Oracle应用,,为客户提供以甲骨文世界级支持服务为后盾的可扩展、低成本的服务器虚拟化。
实现更高性能
通过利用最新的Xen 3.4管理程序和更新的基于Oracle企业级Linux 5.3的dom0内核,Oracle VM 2.2可支持更广泛的硬件,提高硬件虚拟化和并行虚拟化客户的性能、可扩展性和安全性。硬件虚拟化客户操作系统的性能也得到提高,其中包括Microsoft Windows操作系统。
Oracle VM 2.2升级了对Oracle集群文件系统(OCFS2)1.4的支持,利用稀疏文件支持等先进功能,实现更快的虚拟机配置和复制,并帮助用户增强对文件数据分配的控制,从而提高性能和存储效率。
Oracle VM 2.2增加了对多路存储设备的直接支持,这种存储设备可以分配给虚拟机,并提高集群应用的性能。
环保功能、简化管理、节省成本
通过利用Xen 3.4管理程序,Oracle VM 2.2还提供效率更高的CPU电源管理功能,从而实现了更加环保的计算,节省了成本。
通过允许用户在虚拟机中设定虚拟CPU的时序排列优先权,和限制每个虚拟机最多可使用多少CPU时间(按百分比计算),Oracle VM 2.2中的资源管理也得到了加强。由于增强了资源管理,用户现在可以通过直观的Oracle VM管理器浏览界面控制CPU、网络和磁盘I/O的服务质量(QoS)。
Oracle VM 2.2的其他增强功能包括:增强了多种用户界面功能,提高了服务器池主代理自动失效转移的可用性并增强了服务能力和审计功能。

Solutions to Oracle cannot be opened include: 1. Start the database service; 2. Start the listener; 3. Check port conflicts; 4. Set environment variables correctly; 5. Make sure the firewall or antivirus software does not block the connection; 6. Check whether the server is closed; 7. Use RMAN to recover corrupt files; 8. Check whether the TNS service name is correct; 9. Check network connection; 10. Reinstall Oracle software.

The method to solve the Oracle cursor closure problem includes: explicitly closing the cursor using the CLOSE statement. Declare the cursor in the FOR UPDATE clause so that it automatically closes after the scope is ended. Declare the cursor in the USING clause so that it automatically closes when the associated PL/SQL variable is closed. Use exception handling to ensure that the cursor is closed in any exception situation. Use the connection pool to automatically close the cursor. Disable automatic submission and delay cursor closing.

In Oracle, the FOR LOOP loop can create cursors dynamically. The steps are: 1. Define the cursor type; 2. Create the loop; 3. Create the cursor dynamically; 4. Execute the cursor; 5. Close the cursor. Example: A cursor can be created cycle-by-circuit to display the names and salaries of the top 10 employees.

Building a Hadoop Distributed File System (HDFS) on a CentOS system requires multiple steps. This article provides a brief configuration guide. 1. Prepare to install JDK in the early stage: Install JavaDevelopmentKit (JDK) on all nodes, and the version must be compatible with Hadoop. The installation package can be downloaded from the Oracle official website. Environment variable configuration: Edit /etc/profile file, set Java and Hadoop environment variables, so that the system can find the installation path of JDK and Hadoop. 2. Security configuration: SSH password-free login to generate SSH key: Use the ssh-keygen command on each node

Oracle is not only a database company, but also a leader in cloud computing and ERP systems. 1. Oracle provides comprehensive solutions from database to cloud services and ERP systems. 2.
