To run a optimization the users need to be out of Cognos Controller – how can i force users off Cognos controller at night?

Suggested Solution:
The Cognos controller code that handles users are inside the IIS application pool, so a restart of the IIS server will force all Cognos controller users out.

Suggestion is to also restart your Cognos Analytics service at the same time. This simple batch script can do it for you, if you run it from a scheduler with desktop access.

REM restart of IIS and then Cognos
echo ——– >> d:\temp\restartlog.txt
echo %date% %time% >> d:\temp\restartlog.txt
net stop W3SVC
net start W3SVC

echo Cognos Analytics Restart Begins….. >> d:\temp\restartlog.txt
CALL “d:\Program Files\ibm\cognos\analytics\bin64\cogconfig.bat” -stop
echo Services Stopped >> d:\temp\restartlog.txt
REM rename the cognos server log file for later inspection
rename “d:\Program Files\ibm\cognos\analytics\logs\cognosserver.log” “* %Date:/= % %Time::=.%.txt”

REM wait before start
PING -n 31 > nul

CALL “d:\Program Files\ibm\cognos\analytics\bin64\cogconfig.bat” -s

echo %date% %time% >> d:\temp\restartlog.txt
echo Services Started successfully >> d:\temp\restartlog.txt


If you have more than one Cognos server, you need to restart the CA11 Content Manager first, then the rest.  Leave at least 15 minutes between the servers restarts.

If users are logged into Cognos Controller Client during restart, they will see this message when they try to do something inside Cognos Controller Client after a restart.
They need to exit there client.


The drawback is that windows event log will have entry like this:

Faulting application name: cogbootstrapservice.exe, version:, time stamp: 0x5daf2515
Faulting module name: ntdll.dll, version: 10.0.17763.1728, time stamp: 0x6e7b7e33
Exception code: 0xc0000374
Fault offset: 0x00000000000fa689
Faulting process id: 0x128c

The selection of non-production environment is missing from the installation of CA11, why?

New Cognos BI version have that you set the production or non-production from inside the Cognos Connection portal.

After you have done the installation, go into the production environment – go to Manage – Licenses and select Production. Click Apply.

This will make the files in folder C:\Program Files\ibm\cognos\analytics\iso-swid to change names.

You have both a production and non-production file here, CA11 will switch the ending .sample to the file that is not used. It will also keep the file date, so you will not easy notice the switch.

The content of the file does not change, only a smart switch of the file name ending. The ILMT program will pick up this file to report on what type of installation you have.
