How to backup an off-line installation of Cisco WCS 6.0.196.0

Well let’s say you have an error that brings down all your WCS installation and you do not have a recent backup. What can you do? How can you recover the DB?

For this there is a simple answer but first let’s take a minute to analyze the WCS structure. It’s made from three primary components:

  1. the Solid database engine;
  2. the Apache web server engine;
  3. and the Java virtual machine that contains a Java-based SNMP engine. Continue reading

Cisco Wireless Control Station 6.0.196.0 does not start…

In the recent days I’ve had problems with our install of Cisco Wireless Control Station v6.0.196.0. After a system restart, the service did not start and no apparent reasons where given to the user.

The Cisco support wasn’t of much help too, as apparently did not encounter the error before.

Whenever I tried to start the WCS via the batch file the result was an error:

Java Virtual Machine Launcher: Could not find the main class: com.zerog.lax.LAX .

In fact all the batch files associated with the control functions of the WCS (START SERVER / STOP SERVER / DATABASE BACKUP / RESTORE) presented the same error when started.

Also trying to start the WCS service, via the computer management console, did not helped as the service terminated unexpectedly (error 1067).

Using Nagios in a efficient way (in a generic install):

Nagios is a highly configurable monitoring platform. Basically it gives you the possibility to take any output and can monitor it!

It has a great community around it; it’s very well documented and has many, many plug-ins.

There is a free and a paid version available:

  • The Core version gives you the possibility to make the installation in any way you want, but requires some knowledge on how you can get the things done.
  • The paid version (current named Nagios XI) try’s to include a unified interface where the user can administrate the whole Nagios server in one interface.

I know what “I” did last summer!

Having a little time off from the day to day responsibilities I usually have at my work place, last summer I decided to build the map of Italy with all the offices, for our Help Desk.

So, with the magic of Wikipedia (http://en.wikipedia.org/wiki/Italy), Gimp and Mk-livestatus I have done in NagVis, a dashboard that displays live checks of the network and server software. This map is displayed on a TV in the Help Desk room, so that everyone can see the network status. Continue reading

Microsoft launches a self computing guide

Yep! It finally strike them that it does not matter how safe you make a system (not that Windows is the safest system around – but it’s over Apple for example http://news.softpedia.com/news/Macs-Are-Probably-Easier-to-Hack-than-Windows-PCs-Notorious-Hacker-Says-155507.shtml ) the human that uses the system will finally have the final word!
