HP与Oracle在海量数据业务展开竞争

6月20日HP公司发布Vertica Analytics Platform 5.0版，最新版将与HP自己的硬件产品结合到一起。HP在今年早些时候收购了Vertica，这将帮助HP在逐渐升温的海量数据市场发挥关键作用。
Vertica基于列存储。基于列存储的设计相比传统面向行存储的数据库具有巨大的优势。
同时Vertica支持MPP（massively parallel processing）等技术，查询数据时Vertica只需取得需要的列，而不是被选择行的所有数据，其平均性能可提高50x-1000x倍。
Vertica的设计者多次表示他们的产品围绕着高性能和高可用性设计。由于对MPP技术的支持，可提供对粒度，可伸缩性和可用性的优势。每个节点完全独立运作，完全无共享架构，降低对共享资源的系统竞争。在此架构下，添加更多的节点可增加更多的容量和性能。当一个节点出现故障时，不会对整个系统产生影响。其他节点会完成故障节点的任务。
Vertica的数据库使用标准的SQL，同时Vertica的架构非常时候云计算，包括虚拟化，分布式多节点运行等，并且可以和Hadoop/MapReduce进行集成。
HP表示可以单独购买Vertica单纯软件包或购买与四分之一机架（96-core），半机架（192-core）和全机架（384-core）惠普刀片系统捆绑在一起的产品。
HP表示他们的竞争力在于成本只有其竞争对手的一半，并提供多倍于竞争对手的性能。从目前的局面来看，Oracle Exadata System是其主要竞争对手。
Vertica是不是取代Oracle Exadata OLTP的正确选择？当涉及到数据仓库和核心分析时Exadata可能还是好的选择。Vertica的优势在于更加精确、灵活，且维护成本要便宜很多。
惠普首席执行官李艾科表示，这款系统将“为下一代业务智能提供实时分析”，可用于网站流量分析、零售销售的趋势分析或者药物研究。Vertica的客户名单包括Groupin、Twitter、Zynga、Verizon、Comcast、Sprint、At&T等。
惠普已经涉足分析领域，但是通过这款新设备“惠普可以真正打开这个市场，尤其是将分析作为一项服务的市场”。(李智/译)

How to solve the problem of closing oracle cursor
Apr 11, 2025 pm 10:18 PM
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.
