第一题来了:
In a two-node clustering environment configured as Active/Active. Each node
has only one sql server instance running on it. One day system administrator
manually fail over one instance to another node in order to apply system
patch.
After several minutes DBA get alert that the available virtual memory on the
fail over node is very low, question:
1. How to solve this issue?
2. What is your best practice to A/A clustering en |

2. more RAM
btw, A/P model is much safer. |

因为是A/A,所以在failover的时候
failover node要hold failed node的memory
这样的话failover node有可能内存不足
导致virtual memory is low
解决办法是设置Max server memory
2.
设置每个节点的max server memory
保证总和不超过任意一个节点的physical memory
or
增加ram
lz公布一下答案吧,再来几道题给大家做做

z***y 发帖数: 7151 | 4 我说过,大部分都是open question。 但是coolbid回答我较钟意。
我一般设置每个instance 最大内存为每个节点内存的40%.
其他的Coolbid 已经回答的完美了!
