Here is my context:

  • SQL Server 2008 R2
  • Citrix XenApp 6.5

When I was installing my first XenApp server, I faced a wired “BUG”. Usually, I used to copy and past the credentials inside the XenApp interface and then initialize my database. With XenApp 6.5 I received this message:

After trying many things and settings it seems that even if I copy and paste my account credentials, I MUST type again at least one character inside the login and inside the password fields.

If I did that, I receive a beautiful message:

previous post remembered me another annoying thing I’ve faced off. XenApp 6 Citrix Delivery Console let you set reboot policy settings (time, warning messages, frequency, and so on).
For me it was not working. I’ve check the rules several times, checked the registry keys and figured that everything was fine but… always not working.

In fact you must have at least an Enterprise Edition to make it work. It’s not even mentioned in the latest Citrix XenApp Comparative Feature Matrix.

Thanks to everyone in this post for pointing it out:

I’m designing for a customer his new Citrix XenApp 6 farm.
I was wondering why the user’s explorer view was not saved when the user reconnects between servers.
Unfortunately for me, it was the first time I did not use a profile manager under Windows 2008 for managing profiles (Citrix Profile Manager, Appsense, Tricerat and so on). After searching on internet, I discovered that it was something introduced by Microsoft since Windows Vista (It concerns only roaming profiles).

Citrix Profile management is a feature available for XenApp Enterprise and Platinum editions and XenDesktop Advanced, Enterprise and Platinum editions and guess what we use the XenApp advanced edition 🙂

So if you are facing this problem and you care about your explorer view settings under Terminal Server or Citrix then use at least the Enterprise edition for Citrix or use a dedicated software.

I don’t know if you have curiosity to look at your log files. I rencetly launch this command :

tail -f /usr/local/centreon/log/centstorage.log

and I’ve received something like

26/5/2011 22:06:28 - ERROR while updating /var/lib/centreon/metrics/2510.rrd at 1306440385 -> 1 : /var/lib/centreon/metrics/2510.rrd: illegal attempt to update using time 1306440385 when last update time is 1306440385 (minimum one second step)

The problem is how to identify which service is concerned by 2510.rrd ? Continue reading »

Sorry for not updating so often, I was quite busy and as you know, there is only 24 hours in a day 🙂

Go back to our main subject, Merethis has released Centreon 2.2.0

Let-s try to update our ‘old’ config :

cd /usr/local/src
sudo wget
sudo tar -xzf centreon-2.2.0.tar.gz
cd centreon-2.1.9
cp  www/install/sql/centreon/Update-DB-2.2.0-RC2.sql_to_2.2.0.sql www/install/sql/centreon/Update-DB-2.2.0-RC2_to_2.2.0.sql
sudo ./ -u /etc/centreon

Beware and copy the sql file to a new one as there is an error in a filename. If you don’t, you’ll see version 2.2RC2 and not 2.2.0. This will be fixed in version 2.2.1.
