Oracle 参数 OLAP_PAGE_POOL_SIZE 官方解释,作用,如何配置最优化建议
本站中文解释
:
OLAP_PAGE_POOL_SIZE参数是OLAP (On-line Analytical Processing) 分析服务池页面大小参数。它能够用于扩展OLAP服务池内存使用量,增加OLAP服务器的计算处理能力。为确保OLAP参数设置正确,可以根据计算平台的RAM大小和应用的OLAP服务的使用情况定期进行调整。
一般OLAP_PAGE_POOL_SIZE参数的值应该设置为内存总量的60%-80%。此外,该参数值也不应超过物理内存最大值,应保持内存不被完全占用。

Caution:
Oracle strongly recommends that you leave this parameter set to its default value of 0
. This instructs the database to autonomously adjust the OLAP page pool size to serve the requirements of the analytic workspaces. Setting this parameter to a value other than 0
can lead to errors in OLAP processing or wasted memory.
