The specified group does not exist on the server


TM1 10.1.1

Operations Console

Windows 2008 R2 server



Try to login to a Operations Console session, you have enter the following:

adminhost: localhost

servername: planning sample

group: cognos\admin

username: admin

password: apple


Error message:

The specified group does not exist on the server



Operations Console may have problems with group names that contain a \ backslash or other characters. Recommendation to use simple group names likeĀ  MONITOR or ADMIN.



Start TM1 Architect and add a group with name MONITOR

Add users to this group MONITOR that should be allowed to MONITOR the TM1 application.

Exit Architect.


Update the D:\Program Files\ibm\cognos\tm1_64\webapps\tm1operationsconsole\WEB-INF\configuration\ OpsConfig.xml file to reflect the change of group.


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


<AdminHost name=”localhost”>

<Server name = “Planning Sample”>








Opsconfig.xml should look like above. Save the file.

You may need to change localhost with your servername, and planning sample if you want to use a different TM1 application as security container for Operation Console.


Go to Windows services and restart the “IBM Cognos TM1 Application Server” to make changes take affect.

Surf to http://localhost:9510/tm1operationsconsole/ to test the change.
