Product:
Cognos Controller 10.1
Microsoft Windows 2008 R2

Symptom:
When starting Cognos Controller client, it will hang and not show up.

This happens on a client computer (citrix server) that run a 64 bit operation system.

Possible error:
Microsoft IE Execute shell
Microsoft IE Execute shell has encountered a problem and needs to close.
We are sorry for the inconvenience.

Cause:
Cognos Controller is a 32 bit application, and will not execute in a 64 bit Internet Explorer.

Possible Solution:
Set the Client computer (citrix server) to process all NET framework code as 32 bit.

start cmd by select “run as administrator” from start menu on client computer.
go to c: drive
change to folder with command: cd %windir%\Microsoft.NET\Framework64\v2.0.50727
Enter command: Ldr64.exe setwow

More information:
On Windows 2008 R2 server when running Controller Configuration, you must right click the program and select Run as Administrator.

Ensure that the client have trust to the Cognos Controller server.
Check by running CASPOL -LG from the Microsoft.NET\Framework\v2.0.50727 folder on the client. This will list the servers that the NET framework client trust.

When you run the caspol command, you must start the command prompt/bat file by right clicking the program and selecting Run as Administrator.

start cmd run as administrator
cd C:\%windir%\Microsoft.NET\Framework\v2.0.50727
caspol -q -m -ag “All_Code” -url http:// SERVERNAME /* FullTrust -name “Controller_ SERVERNAME ” -d “Controller_ SERVERNAME ”

(replace SERVERNAME with the name of your server NetBios or FQDN depending what you have setup)
Run the CASPOL command once for FQDN and once for the NetBios Servername to ensure the clients access to the server.

Microsoft Windows 2008 R2

Symptom:
The Cognos Controller client freeze (hang) after you have selected the database to use. The login dialog is not showing up. There are no error messages in windows event log.

If you run Controller Client direct on the Controller Application server – it works fine.
But from all client computers the Controller Client will hang.

Problem:
When Cognos Controller client start it will contact Cognos connection to check if it is there, even if you use native controller security. When report server setting is http://localhost/ibmcognos/cgi-bin/cognosisapi.dll , this will not work – Cognos connection can not be found on the local client.

You can sometimes get a Internet Explorer 404 error in Controller before the login dialog.

Cause:
After you have applied the Cognos Controller hot fix, the settings in Controller configuration is reverted back to default values. Therefore the Report server value is localhost and not the server name.

Solution:
Open Controller Configuration on your Controller server.
Go to the Report Server tab.
Change the url from localhost to the servername

Report server should be:
http://srv001/ibmcognos/cgi-bin/cognosisapi.dll

Dispatcher URI should be:
http://srv001:9300/p2pd/servlet/dispatch

(change srv001 to your server name)

Click save and close.
Test again.

Issue:
How automatic set the background picture in Cognos controller for all clients on a Citrix server?

Inside Cognos Controller client, you can define a BMP file to be used as background picture.
Recommended is to have a different background picture for your test environment.
To make Controller Client color different from the productions clients.

In Cognos Controller client go to
Maintain – Installation – Local Preferences
Here you can enter the key app_background
And a value that points to a local BMP file.

Problem:
Local Preferences values are stored in the ccr.config file for each user in there windows profile.
You need to populate this file for each user when they logon to the Terminal Server.

Solution:
On citrix server create a folder called d:\script
On citrix server create a BMP file and save it as c:\windows\background.bmp
On citrix server download AUTOIT3:EXE from http://www.autoitscript.com/site/autoit/downloads/
And place it in folder d:\script

Create a text file in folder d:\script named replaceccr.au3 with this content:

$TextFileName = @UserProfileDir & “\AppData\Roaming\Cognos\ccr\ccr.config”

$FindText = “”
$ReplaceText = ‘ ‘

$FileContents = FileRead($TextFileName)
$Check = StringInStr( $FileContents, “” )

if $Check = 0 Then

$FileContents = StringReplace($FileContents,$FindText,$ReplaceText)
FileDelete($TextFileName)
FileWrite($TextFileName,$FileContents)

EndIf

Create a text file in folder d:\script named updateccr.cmd with this content:
d:\script\autoit3.exe d:\script\replaceccr.au3

In folder d:\script these files should now be:
Autoit3.exe = used to process au3 script files
Replaceccr.au3 = will check the users ccr.config file and add the “app_background” if it does not already have a “LocalPref” value.
Updateccr.cmd = file to run to active the script

You may then add the updateccr.cmd file to your C:\Windows\System32\usrlogon.cmd, to make it run when anyone logon to the Windows Server.

Problem:
How to install the Cognos Controller client automatic?

Cause:
Sometimes the IT department want to automate the installation of the Cognos Controller Client on the client computer or Citrix server.

Solution:
You can from a script start the CCRLOCALCLIENT.MSI file and add parameters that will respond to the questions you get when you install.

Copy first the CCRLOCALCLIENT.MSI file to the Client Computer.
You can download it from
http://servername/cognos8/controllerbin/ccrlocalclient.msi

Enter below on ONE row in a DOS prompt on the client computer:
msiexec.exe /qb /i ccrlocalclient.msi WSSURL=http://servername/cognos8/controllerserver HELPURL=http://servername/cognos8/controllerhelp

Replace servername above with the name of your Cognos Controller server.
