表缓存,表空间缓存,屏幕缓存,编号范围缓存等等
重置请慎重,会影响SAP性能
下面有几个常用缓冲区重置的功能
/$SYNC - buffers of the application server
/$CUA - CUA buffer of the application server
/$TAB - the TABLE buffers of the application server
/$NAM - the nametab buffer of the application server
/$DYNP - the screen buffer of the application server
SAP HANA 是市场上首个 translytical 数据平台,也是数据库领域的领导者。SAP HANA提供多用途的内存应用设备,企业可以利用它即时掌握业务运营情况,从而对所有可用的数据进行分析,并对快速变化的业务环境作出迅速响应。通过SAP HANA,企业可以在业务运作期间基于海量实时详细信息分析业务运营情况。企业可以探索和分析来源于所有数据源的全部交易数据和分析数据。运营数据在产生时由内存获取,并通过灵活的视图迅速将分析信息呈现给用户。外部数据可轻松的被添加至分析模型,与整个企业的数据进行整合。
通过SAP HANA 可直接访问运营数据,而不影响SAP ERP和其他运营系统的性能。企业可以近乎实时地将主要交易表同步到内存中,以便在分析或查找时能够轻松对这些表进行访问。一旦数据可通过内存访问,各个部门就可以从预订单据、销售线索、服务要求等大量列表中查找单个行项目,而不会对运营系统造成任何影响。这种高效的建模流程支持提供明细行项目的直接访问模型,以及支持更为复杂的分析流程的分析模型。
