Notify me about server failure

May 25, 2009 03:32 by alexk
Hi everyone, sorry for keeping your waiting for my next post so long time. I was busy on Android OS investigation. But now I'm back.

Introduction


Do you know how to check is your server is still running and give your customers something? No. Then you should go to administrator room and ask technical stuff there. I think after hearing the answer you will be a little disappointed. On market still does not exist simple and easy solution.
Microsoft suggest to use there servers that cost a lot; several vendors suggest to buy there services (InternetSeer for example), others simply waiting customer feedback and re-act on it.
I think this is not right. It's time to change those things. I have to feel my servers on fingers, and re-act faster then any customer catch the problem.

Concept


In our company we have several servers each one specially installed for particular task. For administrator is critical to check stability and availability of those servers. But administrator can not sit 24/7 and watching servers. So we need small automation here.

Several questions from the begging catch my attention:
1) if all servers in domain failed, how I can receive notification about that? What happens if internet channel become broken physically?
2) How I can detect that several services on server stop working properly?
3) Can I provide some "sugar" for solution?!

So I start thinking and designing. Phone call interrupt me for a minute, but also give me a nice idea: GSM Modem can become a backup channel that can notify me about server problems.
WOW! Its was very nice idea and easy to implement. 10 minutes and GSM modem was ordered over internet. My choice is: NOVACOM GNS-30 CRA. It cost a little, it done in industrial standard metal case, easy to mount, easy to program.
NOVACOM GNS-30 CRA ... >>>

OracleDecimal and ODP.NET IConvertable exception

October 1, 2008 17:49 by alexk

Oracle ODP.NET

I'm working now on a new project that in internals use ODP.NET - ORACLE Data Provider for .NET and latest Oracle 11g.

First of all I want to mention that ODP.NET is a great disappointment for me. In writing of very simple a stupid code ODP give me so many issues that I start to think that ORACLE completely loose own mind and release very unstable library for developers. I loose 2 days for fighting with found issues and I hope my article will help others a lot.

Simple Scenario that does not work in ODP.NET

Let's start from the simple scenario: Create typed DataSet with several tables, infill dataset by the data and update database by that data. Primary keys of the rows must be updated by Adapter automatically on Update method call.

IP geo-location - make it easy!

September 11, 2008 02:49 by alexk

Introduction

Today I want to open one more interesting part of making internet business - statistics collection. I hope you already knows popular service Google Analytics that helps many companies to track internet activity on web site (main issue that those analytics is not runtime, you have to wait 1 day for getting ready to use statistics). But do you want to know how to make own statistics tracking engine on IIS? I hope you do.

In this article I will describe how to collect statistics from IIS and how to do most common thing - resolve clients IP into geo-locations.

Theory

Let's make a quick look on web site hosting. What we can see? Let's count:

  1. IIS hosting server
  2. Web site (for example ASP.NET)
  3. Database (for example MS SQL Server)

Those 3 components are the most common for every web site based on Microsoft technologies.

Statistics tracking can be done only on first two components: IIS and ASP.NET... (but this is not exactly true, if take a look into depth then we can identify that in reality we have only one component IIS and it's filters model - ISAPI filters.)

Tracking of statistics on IIS layer is well described by Microsoft in own knowledge database.
