发帖数: 1119 | 13 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 ... 阅读全帖 |

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

发帖数: 1119 | 15 Either bridged network or NAT is okay. The key is to use static ip instead
of dhcp. |

发帖数: 108 | 16 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.

发帖数: 34098 | 20 我个人认为学习解决问题的方法远比学习一个知识点重要得多。
以你写的code为例，大家来探讨一下：
UPDATE INVENTORY
SET stockqty = (SELECT INVENTORY.stockqty - v_qty
FROM INVENTORY
WHERE INVENTORY.partid = v_Partid)
WHERE partid = v_Partid;
这个你自己看着都觉得别扭，怎么办？当然，去问会的同学也是一种方法，但肯定不是
最好的。
学习第一大法，***读文档***
找到oracle 11gR2的关于update的文档（怎么找到文档的?晕倒)。
http://docs.oracle.com/cd/E11882_01/server.112/e17118/statement
一共没几行，里面已经给出例子能解决你的问题。
如果你仔细阅读这篇文档，你会发现你的code还可以继续优化。基本上就解决了另外一
个问题，为什么update后还要再用一... 阅读全帖 |

我们最近才升到11g r2。估计几年后才会升到12吧。不管什么版本，我们developer用
的也不过就是些简单sql，好像用不着这些新功能。不过最近俺写了个query用了
LISTAGG，把我们办公室的16年经验的大牛给震惊了一下，说从来不知道这个东东。后
来一查，这个function从11GR2才有的。
俺以前也参加过一次Oracle BI的发布会，早饭中饭都管，还有帽子随便拿。反正是上
班时间去，今后有还去。呵呵。 |
