Cognos BI 8.4.1
Windows 2008 R2 Server

User get a error when they try to surf to Cognos connection using an old shortcut on the desktop.
It have worked the other day.

Error message:
404 – File or directory not found

The IIS on Windows 2008 server is stopped to allow CGI.

This is simply done by inside Internet information services manager,
go to the server and click on “ISAPI and CGI Restrictions”
on the right side click on “Edit Feature Settings”
in the dialog Edit ISAPI and CGI Restrictions Settings
uncheck “Allow unspecified CGI modules”
and leave “Allow unspecified ISAPI modules” checked
click OK

This will stop all CGI access to the IIS server, if you not have explicit added exceptions in handler mappings.

Ensure the user surf to http://servername/cognos8
instead of http://servername/cognos8/cgi-bin/cognos.cgi

Recommendation is to use cognosisapi.dll instead of cognos.cgi on Microsoft Windows server because they use less windows resources.

Cognos BI 10.1.1
Windows 2008 R2 server

After restart of the Cognos BI server you can not get into the Cognos connection or that the Business insight give error :

DPR-ERR-2014 Unable to load balance the request because no nodes in the cluster are available, or no nodes are configured for the service: buxService.

You have a two server setup,
One server with Cognos Content Manager and Cognos Gateway (named A)
One server with Cognos Application tier ( for BI reporting, named B )

The Cognos Configuration is pointing the primary dispatcher to the Cognos Content Manager server A, but this server does not have all the functionality installed to handle the dispatcher actions.

If you restart server B, then it will point to server A for actions, and server A have the dispatcher service – but not the associated functions needed to perform all actions.

Boot of Cognos servers:
In all Cognos system the server containing the Cognos Content Manager service must be started first. After that the other Cognos BI serves can be started.

All servers and gateway must point to the Cognos BI App Servers dispatcher as the only and primary dispatcher for the gateway. This is on server B.

If you want to use the Content Manager server A as primary dispatcher, you must install the Cognos Application tier there.
Then you need to set Report service and Batch Report service to false in Cognos Configuration on Server A, to prevent the heavy reports to be processed on that server.

During the installation of Cognos Controller not all parts was correct installed.
You find this if you look on the Cognos Controller application server in Component Services under Administrative tools.
Expand the Com+ Applications branch and then expand IBMCOGNOSCONTROLLER Components branch – if there is only 30 objects in here then you have the cause of the problem.

Uninstall Cognos Controller 8.5 from the Application server.
Install same Cognos Controller 8.5 to the same folder on the Application server.

Then you have all the components in the Component Services.

Cognos Controller 8.5 Fixpack 1 should have 259 Objects in Components Services.

The SQL login that is used to access the Cognos Controller database have a = sign in the password.

Change the password used by the SQL login Cognos to the controller database to only contain letters and numbers (e.g. A-Z, 1-9)
Then change in Cognos Controller Configuration for the database connection to the new password for access to the Controller database.
Save the change and restart the Controller Application server to allow the controller services to understand the change in connection to the database.

Cognos Controller 8.4

It takes long time to start the Cognos Controller Client.

It takes exactly 90 seconds between you enter your name and password in Cognos Controller until the program is open and you can start to work with it.

The Cognos Controller program is signed with a certificate. During start of Cognos Controller the application will try to contact the certificate authority to check if the certificate is valid. If the computer (or citrix server) where Cognos Controller software is run from does not have internet access, the Cognos Controller program will try for 90 sec before it times out and shows the program anyway.

Uncheck the “check for publisher certificate revocation” in Internet Explorer for the user on the server.
Easy is to create a script that set it to all users that logon to the Citrix Server:
The script will set values in the users Windows profile for Internet Explorer.
To make the script run for all persons add it to the file c:\windows\system32\usrlogon.cmd

Create a text file name UNCHECK.REG with this content in the c:\ root;

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\WinTrust\Trust Providers\Software Publishing]

Then add the following line to the beginning of the USRLOGON.CMD file

regedit /s c:\uncheck.reg

Save the file.
Ensure that all users have read rights to the file uncheck.reg on the server.

This should also be done on the Cognos Controller Applications server, to ensure fast start of the Cognos Controller Configuration program.

Cognos BI 8.1 Reportnet

How do I erase old transformer mdc cube files from a folder?

In many cases you create a new powerplay cube file every night with Cognos transformer. Then you get a lot of MDC files in a folder. But you want the old cube files to be erased.
In the creation process of the powercubes MDC file you add the date in the name as;

Create a batch file that contains below text,
Place the script file erasecube.cmd in the same folder as the mdc cube files.
Run the script as part of the cube build process.
The script will erase all MDC files that do not have today’s date in the name.

Rem checks today date and format it to the variable currentdate
set currentdate=%date:~3,4%%date:~8,2%%date:~11,2%

rem List the cubes to be deleted
dir /B *.mdc | find /V “%currentdate%” > delete.list

rem Deleting the cubes
for /F %%j in (delete.list) do del /Q %%j

rem Deleting the list of used above
del /Q delete.list

Ensure you test the script before you use it in production.

You must change the line “set currentdate=%date:~3,4%%date:~8,2%%date:~11,2%”
to get it to work with your regional settings on the computer.

MS-DOS function date:~3,4 where 3 is the position before first character to use, and 4 is the number of characters to use in the date string.

In a MS-DOS prompt on the Cognos server;
Check today’s format by type DATE /T in the prompt
You may see the date as 2010-03-26

Then you need to change the currentdate line to reflect this
set currentdate=%date:~3,4%%date:~8,2%%date:~11,2%
Above may give that variable currentdate is “0-0326”.
You change the line to be like below to get the right format.
set currentdate=%date:~0,4%%date:~5,2%%date:~8,2%

You can check by run above command in MS-DOS box
Then enter %currentdate% to see the value in the variable.
‘20100326’ is not recognized as an internal or external command,
operable program or batch file.
