即将进入国际金融专业学习(具体说是经济与金融专业国际班),但是听说本专业会强化
数学
理论知识(理科系),这样一来在选
课和学习精力分配上有些疑惑,对于数学学习应该重视到什么程度，前两年都是平台课,如
如果对数学过分重视会不会导致主干学科的理论基础不扎实?恳请学长们说说经验了.谢
过先^_^

Good effort! Thanks for sharing.
Would be nice if doing some testing/simulations on the RAC to demonstrate
its features.
Previously I have done some test about load balancing on a 10g RAC, for
example:

unless you are majoring in math, your success in any field depends on your
intuition, intuition and intuition.

Nice blog!
I configured a couple of 10g RAC (both are 2 node on Linux) last year to
host a sort of mixed but more DW intensive application. If I turn on LB (
either client side or server side), the performance got hit pretty bad due
to heavy traffic on interconnect (gigabyte switch). I have to disable LB for
for those 10g RACs to pass the performance testing. Now there are both
running well for about 6 month in production without LB. Maybe a bias, but
it seems to me disabling LB might be a best practice for performance in some
cases.
From your experience, are you running into any situation like this?
Now I am setting a 11G RAG system, got the machines shipped here last week
and in the middle of installing OS and configure network and SAN storage.
Quickly going through the 11g RAC installation guide, I noticed there is a
new concept called SCAN, which is used for client connection. It seems to me
to use SCAN, Load Balance will have to be enabled. I am not sure how that
is going to work out for our performance testing, but I will find out.
BTW, thanks for sharing your blog and keep up the good work!

确实是这样，虽然爱因斯坦说天才等于1%的灵感加99%的辛勤，但是他可没说那99%的辛
勤能弥补1%的灵感差异。

Thank you for sharing.
You used Bridged network in the description, while the graphs showed NAT.
Which did you actually use?
Thanks.

Either bridged network or NAT is okay. The key is to use static ip instead
of dhcp.

RAC has high demand for interconnect. enable jumbo frame on the dedicated
interconnect subnet helps with bandwidth related "waiting time".
RAC is good for a well tuned system. It could be performance killer for
poorly tuned application/system.
