java - Tomcat 6 cluster with shared objects -


We have a large cluster of Tomato servers and I find an efficient way to share a number between them I am trying. This calculation is the number of purchased "widgets" and should be checked for each pageview. Any server can meet a sales and salary increase, at which point the new value should be made available to all cluster members.

We do not want to use the counting from the database because it is unnecessary to get DB for many page views and views of each page between all the updates of the cluster.

We have a comprehensive memcatch cluster where we can store the value, get it on every page view, and whatever the value updates it sets the new value to the cluster. It is useless again because a page for the view of each page gets a cache.

What I want to do, there is an in-memory value on each server and a multicast (or similar mechanism) message tells all servers that they have just increased and the new number is X. It appears to be the most effective because only one action is taken when every page is updated instead of working for the scene.

How have you handled it in your applications? Am I thinking more about this ... should we just throw it in a memcatch?

Thank you!

If you already have a meconnected infrastructure, then I do not know why you use it It should not be that this will be ideal for it. It will be useless in sea or another drop, only test will tell you. Architecture will be as easy as compared to starting some sculptures or other cache sharing systems as infiltration.

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
