Symptom

Cause
As designed.

Solution
Select one of the formats available (depending on which Excel version the Controller users will be running):
.xls – Compatible with Excel 2003.
.xlsx – Excel 2007 format, not compatible with Excel 2003 or earlier.

Symptom

When opening controller after migration of the controller databases from SQL2000 to SQL2005 the following error occurs after providing login credentials;

“—Exception has been thrown by the target of an invocation”

Problem
In the event log of the controller application server the following entry can be found.

The VB Application identified by the event source logged this Application FrMiscST: Thread ID: 6108 ,Logged: Error occured at 9/14/2009 6:15:11 AM in FrMiscST, Error No=-2147217900, Source=Server Sub:Db_PushStruc(..) , Description=Cannot resolve the collation conflict between “Latin1_General_CI_AS” and “SQL_Latin1_General_CP1_CI_AS” in the equal to operation., HelpFile= HelpContext=0

Cause
The collation settings of the new server is different than the original one. For controller all the collation settings of the temp db and controller databases must be the same collation.

Solution
Create new SQL2005 instance or perform a complete new SQL2005 server installation with the correct collation. In this case “SQL_Latin1_General_CP1_CI_AS”

Symptom
User launches Cognos Controller. User notices that the quick-link/shortcut icon to launch Excel is grayed out, and they cannot use it to launch Microsoft Excel.

Cause
User(s) belong to a security group which has the selection “Reports – Controller Link” configured. But its “Access Rights” are set to “Not Available”

Solution
1. Click “Maintain – Rights – Security Groups”
2. Select the tab ‘Menus’
3. In the ‘Code’ section, select the group which the user(s) belong to
4. Locate the entry for ‘Reports – Controller Link’
5. Change the setting ‘Access Rights’ from ‘Not Available’ to ‘Normal’.

Product:
Cognos Controller 10.3
Microsoft Windows 2008 R2 server
Oracle Database 12c

Symptom:
Error when you do optimize of the database inside Cognos Controller 10.3 in a new installation.

Error message:
Number: 5
Source: System.Web.Services
Description: System.Web.Services.Protocols.SoapException: Server was unable to process request. —> System.ArgumentException: ORA-12516: TNS:listener could not find available handler with matching protocol stack
at Microsoft.VisualBasic.
…

Cause:
The Cognos controller use more connections to the database server than the database server is setup for.

Solution:
Increase the max Connections value for the Oracle server from 500 to max 1000.

The Cognos Controller 10.3 can create 300 inactive connections to the database during some heavy processes. If the oracle database use around 90 connections for internal use, then you soon hit the limit of 500 on the Oracle database.

Solution:

You need to register the ASPNET with IIS on the Microsoft Windows server.

Start a CMD prompt as an administrator on the Controller servers.

1. In a command window, go to the c:/Windows/Microsoft.NET/Framework64/v4.0.30319/ directory.
2. Enter the following command:

aspnet_regiis.exe /i

Repeat on all Cognos Controller servers, and for Cognos Controller 10.2 and 10.3 you need to use NET framework 4.5.6 that is in folder /Framework64/v4.0.30319/.

This is the response you should get from the command:

C:\Windows\Microsoft.NET\Framework64\v4.0.30319>aspnet_regiis /i

Microsoft (R) ASP.NET RegIIS version 4.0.30319.0

Administration utility to install and uninstall ASP.NET on the local machine.

Start installing ASP.NET (4.0.30319.0).

Solution:

The WEB.CONFIG file is not correct in the cgi-bin folder on the IIS for the Cognos Controller installation.

It can have been edit and a > character is missing or the “ is not of the correct type.

Open the file in notepad and enter the value manually

Do not copy and paste it from the website. That will give errors.

Using Windows Explorer, open the cgi-bin folder (default = C:\Program Files\ibm\cognos\ccr_64\cgi-bin)

• Launch NOTEPAD.EXE and edit the file ‘web.config’

TIP: From Windows 2012 onwards, it is not possible to edit files directly unless logged on as the user ‘Administrator’. One easy workaround is to launch a Command Prompt ‘As Administrator’ and (inside there) type: NOTEPAD.EXE.

• Add the text allowPathInfo=”true” after the entry: resourceType=”xxxxx”

The text should look similar like this inside the web.config file:

<?xml version=”1.0″ encoding=”UTF-8″?>

<configuration>

<system.webServer>

<handlers>

<add name=”IBMCOGNOSISAPI” path=”cognosisapi.dll” verb=”*” modules=”IsapiModule” scriptProcessor=”C:\Program Files\ibm\cognos\ccr_64\cgi-bin\cognosisapi.dll” resourceType=”Unspecified” preCondition=”bitness64″ allowPathInfo=”true” />

<add name=”IBMCOGNOSCGI” path=”*.cgi” verb=”*” modules=”CgiModule” resourceType=”Unspecified” allowPathInfo=”true” />

</handlers>

</system.webServer>

</configuration>

After the update enter IISRESET to restart the web service on the Windows server.

Then test to start the Cognos Controller client again.

Then start the Cognos Controller Configuration and test the connection to database again.

If above does not work, then you need to reinstall the Oracle drivers in a correct manner.
