Description: Hash join算法的一个基本思想就是根据小的row sources(称作build input，我们记较小的表为S，较大的表为B) 建立一个可以存在于hash area内存中的hash table，然后用大的row sources(称作probe input) 来探测前面所建的hash table。如果hash area内存不够大，hash table就无法完全存放在hash area内存中。针对这种情况，Oracle在连接键利用一个hash函数将build input和probe input分割成多个不相连的分区（分别记作Si和Bi），这个阶段叫做分区阶段；然后各自相应的分区，即Si和Bi再做Hash join，这个阶段叫做join阶段。
如果在分区后，针对某个分区所建的hash table还是太大的话，oracle就采用nested-loops hash join。所谓的nested-loops hash join就是对部分Si建立hash table，然后读取所有的Bi与所建的hash table做连接，然后再对剩余的Si建立hash table，再将所有的Bi与所建的hash table做连接，直至所有的Si都连接完了。
Hash Join算法有一个限制，就是它是在假设两张表在连接键上是均匀的，也就是说每个分区拥有差不多的数据。但是实际当中数据都是不均匀的，为了很好地解决这个问题，oracle引进了几种技术，位图向量过滤、角色互换、柱状图，这些术语的具体意义会在后面详细介绍。

Description: 调用BIEE提供的web service
门户项目中准备用web service获取现有的制作好的报表进行展示。遂去研究了下，研究的过程也是满纠结的，总算根据多方资料，将demo跑通了。
本文参考了网上的一些资料，做一下总结而已。讲解下如何配置，成功的获取到相关报表。
biee的web service的介绍我就不说了了，官方文档如下：
http://download.oracle.com/docs/cd/E21764_01/bi.1111/e16364/soa_overview.htm
提供的服务如下：
http://download.oracle.com/docs/cd/E12096_01/books/AnyWebServ/AnyWebServTOC.html
使用axis生成WEB service的客户端代码：
步骤参考：
http://gerardnico.com/wiki/ide/eclipse/eclipse_how_to_consume_a_webservice_with_wtp
需要指定包名为：com.siebel.analytics.web.soap.v5
客户端代码生成后，在eclipse下由于下载了插件依赖包都是有的，所以可以直接写一个java程序去测试下是否调用web service成功。-Web service portal project calls BIEE provided ready access to existing web service by making good reports on display. Then went to study under the research process is full of tangled, multi-information and finally based on the demo run through. This reference to some of the information online, do some summary only. Under explain how to configure the successful acquisition of relevant reports. biee the web service' s introduction I will not say, and official documents as follows: Service http://download.oracle.com/docs/cd/E21764_01/bi.1111/e16364/soa_overview.htm provides as follows: http://download.oracle.com/docs/cd/E12096_01/books/AnyWebServ/AnyWebServTOC.html using axis generated WEB service client code: Step Reference: http://gerardnico.com/wiki/ide/eclipse/eclipse_how_to_consume_a_webservice_with_wtp need to specify package called: com.siebel.analytics.web.soap.v5 client code generation later, in the eclipse because the downloaded plugin dependencies are there, so you can dire
