Cognos Controller 10.4.2
Microsoft Windows 2019 server
Microsoft SQL server 2016


When open data entry, you get a system.exception error:

Source: ControllerForms12
Description: System.Web.Services.Protocols.SoapException: Server was unable to process request. —> System.Exception: Cannot resolve the collation conflict between “SQL_Latin1_General_Pref_CP1_CI_AS” and “SQL_Latin1_General_CP1_CI_AS” in the equal to operation.
at Microsoft.VisualBasic.ErrObject.Raise(Int32 Number, Object Source, Object Description, Object HelpFile, Object HelpContext)
at ControllerServerCommon.RaiseErrSrv.RaiseException….

This on a new SQL server installation, where you have restored your Controller database backup.


Change collation settings on the SQL server. Cognos Controller demand that the SQL server and its TEMPDB have the same collation as the controller databases. Therefor you often have dedicated SQL servers for Cognos Controller systems.

Recommended format is: “SQL_Latin1_General_CP1_CI_AS”

Other collations will work, as described here:

You can change the SQL server collation without reinstall it, by this hidden feature.

  • Stop all Cognos services.
  • Detach all user databases (right click on Controller database in SQL manager and select Tasks – Detach)
  • Make backup of all other stuff
  • Stop SQL Server Service – can be done in Windows services.
  • Start a CMD prompt as Administrator
  • Go to folder C:\Program Files\Microsoft SQL Server\MSSQL13.MSSQLSERVER\MSSQL\Binn
  • Start the SQL Server Service using this command:
    sqlservr -m -T4022 -T3659 -q”SQL_Latin1_General_CP1_CI_AS”
  • Now check for the message “Recovery is completed”, and then press CTRL+C to Stop the SQL Server service
  • Start the SQL Services Normally – from Windows services.
  • Check for the change in SQL Management Studio with below query:
    select serverproperty(‘COLLATION’) as servercollation
  • Attach the user databases back (right click on Databases in SQL manager and select Attach)

Use this with extra care and with your own risk!

Cognos Analytics 11.1.7

Microsoft Windows 2016 server

Only one user get a error when running a report in CA11, after he have logged in with SSO, if he do not use SSO with IIS, and instead enter name and password at Cognos dialog, then the report works.

A check of the users – showed he belongs to a lot of domain groups.

net user  donaldduck  /DOMAIN   >  c:\temp\userlist.txt

Error message:

HTTP Error 400. The size of the request headers is too long.


Increase the allowed header size on the Cognos Gateway server

Windows Registry Editor Version 5.00




Login to the server, and start REGEDIT program.

Expand to [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HTTP\Parameters]

Add the DWORD values.

You must restart the Windows server, for the registry changes to take affect.

You may also need to update the TCPIP values:

Windows Registry Editor Version 5.00


or change the IIS \ibmcognos\bi folders Request Filtering to a higher value, to get the report to work.


More information:

Although each web server software has some limitations, there is a difference whether there’s a limit for the HTTP request line plus header fields or for each header field.

Here’s a summary:

  • Apache 1.3, 2.0, 2.2, 2.3: 8190 Bytes (for each header field)
  • IIS:
    • 4.0: 2097152 Bytes (for the request line plus header fields)
    • 5.0: 131072 Bytes, 16384 Bytes with Windows 2000 Service Pack 4 (for the request line plus header fields)
    • 6.0: 16384 Bytes (for each header fields)
  • Tomcat:
    • 5.5.x/6.0.x: 49152 Bytes (for the request line plus header fields)
    • 7.0.x: 8190 Bytes (for the request line plus header fields)

So to conclude: To be accepted by all web servers above, a request’s request line plus header fields should not exceed 8190 Bytes. This is also the limit for each header fields (effectively even less).

You can edit tomcat/conf/server.xml’s HTTP/1.1 Connector entry, and add a maxHttpHeaderSize=”65536″ to increase from the default maximum of 8K or so, to 64K


Cognos Controller Client 10.4.2
Microsoft Windows 10

During manual install of ccrlocalclient64.msi on a users laptop they get a error message.

Installing a program on a workstation demand that you are local administrator on that workstation.
In many cases, this is not allowed at companies, but you can get a temporary different user account that is local administrator.

But even when you use this temporary admin account, during installation, you get above error.


First ensure that you account is local admin on the computer.

It should belong to a global Active Directory group that you can find in the list of administrator groups on the laptop.

The command net user adminDonald /DOMAIN will show the groups the account is part of.
Then check that one of these groups is part of the Administrator group on your computer.

Press the Win + R keys on your keyboard to open Run, enter the command compmgmt.msc, and then press Enter or OK.

Go to groups and click on Administrators to see what groups are listed.
If the group is in the list, that account is local admin on the workstation.
If it still does not work, ensure the workstation name is listed as allowed (see below).

If you run the below command for user Donald, you get a result similar to this.

C:\Windows\system32>net user adminDonald /DOMAIN
The request will be processed at a domain controller for domain

When try to change a old data source, in Cognos Analytics, the icon to change setting is missing.

Go to IBM Cognos Administration from the Manage menu by click on Administration console.
Click on Configuration tab.
Select the data source connection you want to change. For example Audit.

Then click on the more link for that data source.

Now click on Set Properties.

Click on the connections tab.

Here is now the pencil icon missing. This can be because the data source type is Other.


Then you need to edit the data source direct in the string field.
Here you can change to other database server.

^User ID:^?Password:;LOCAL;OL;DBInfo_Type=MS;Provider=SQLOLEDB;User ID=%s;Password=%s;Data Source=SeRvErNaMe;Provider_String=Initial Catalog=AUDIT_PRD;@COLSEQ=

After you changed the Data Source value to your database server, click on OK.
This can be because the new version of CA11 does not support SQLOLEDB anymore.

Click on the link to test the data source again.

Click TEST button.

You should get a “Succeeded” Status if it works right.

How configure the agent-config.yaml file to work?

The new windows agent for Grafana Cloud should make it easy to collect some metrics from your  computers to the dashboard in the cloud.

Sign up for a account at

Download the agent and install the agent from here

If you click “Get Started with Grafana”, from your page, you will see a list of local agent you can install to collect metrics (data) from your system. Click on Windows exporter and Next.

After you have configure the windows agent, as below, you can go back to this page and click “Test integration and finish installation”.

There is a default agent-config.yaml file created, where you need to add your url and username to make the agent ship data to the grafana cloud.
You get your Password (API key) on your host page – go to your name under grafana cloud, and then click on prometheus details to get the key and urls.  Click on grafana details to go to your cloud dashboard.

You need to copy the following values, and place in your yaml file.
Remote Write Endpoint (Use this URL to send Prometheus metrics to Grafana Cloud.)
Username / Instance ID (Your Grafana Cloud Prometheus username.)
Password / API Key (Your Grafana Cloud API Key. Be sure to grant the key a role with metrics push privileges.)

Open C:\Program Files\Grafana Agent\agent-config.yaml in notepad++ on your computer.

You need to add the lines remote_write (very important that every line is indent with two spaces)

  - url:
      username: (the user number from your account)
      password: (the long password from your account)

In YAML file is important to indent the text correct, and the order of the lines, have a meaning. Above setup worked for me, to send data to the grafana cloud. You may find other configurations, also work well.

Then go to your page, and select “integration – Windows Exporter” dashboard.

Monitoring Windows Services with Grafana, InfluxDB ‎and Telegraf

You will soon fill up your free account, so you must limit the services that is reported up to the cloud.

Add last to your agent-config.yaml file this lines, to limit the information collected:

 # List of collectors to enable
 enabled_collectors: "cpu,system,os,cs,time"

You can copy your text to a YAML checker:

Here is some information of possible values in the file:

cpu CPU usage
cpu_info CPU Information
cs “Computer System” metrics (system properties, num cpus/total memory)
net Network interface I/O
os OS metrics (memory, processes, users)
process Per-process metrics
remote_fx RemoteFX protocol (RDP) metrics
service Service state metrics
smtp IIS SMTP Server
system System calls

More Information:

For a full description of configuration options, see windows_exporter_config in the Grafana Agent documentation.

After installation, the Agent config is stored in C:\Program Files\Grafana Agent\agent-config.yaml. Anytime the config file is modified, run the following to restart the Windows Agent so it can pick up changes:

sc stop "Grafana Agent" 
sc start "Grafana Agent"
