I was experimenting with the Channel.Qos function and discovered that the only legal value of prefetch_size is zero. Any other value results in: error: Exception (540) Reason: "NOT_IMPLEMENTED - prefetch_size!=0 (1)": failed to set QoS o...
lDEFAULT_PREFETCH_SIZE 项目 2018/05/31 The lDEFAULT_PREFETCH_SIZE constant defines the default prefetch size for incoming and outgoing message iterators. The default is 100 messages. Requirements 展开表 Minimum supported client Windows XP [desktop apps only] Minimum supported server Windows Server...
A prefetch unit is used, in an exemplary embodiment, in a superscalar, superpipelined microprocessor compatible with the x86 instruction set architecture. Normally, the prefetch unit performs split prefetching by generating low and high prefetch addresses in a single clock, with the high prefetch ...
Hi, Acoording to the OSS note#1109753, SAP advises to deactivate the prefetching feature by putting the parameter TABLE LOOKUP_PREFETCH_SIZE =0. I understand the
A microprocessor () comprising a cache circuit () and circuitry () for issuing a prefetch request. The prefetch request () comprises an address () and requests information of a first size () from the cache circuit. The microprocessor also includes prefetch control circuitry (), which comprises...
--//1.显示输出行数 第1次 floor(rowprefetch/arraysize)*arraysize.--//注:.如果rowprefetch < arraysize,第1次fetch后,不足arraysize数量.不会马上输出,而是等待下一个fetch完成,再输出.--//2.显示输出行数 第Y次(Y>=2) floor((前次剩下的记录+本次fetch的记录)/arraysize)*arraysize.--//注:...
