before
you can save a configuration.You can change a property value from the default value, or from one that you previously set, to suit your environment.
For example, you may need to change a port number if it is being used by another process.
When you change the value of a property, Cognos Configuration checks whether you typed the correct data type and, if applicable, whether the value is in the required range.
You must specify values for mandatory properties before
you can save a configuration.
Start Cognos Configuration.
In the Explorer window, click the group, component, or resource you want.
The Properties window shows property values for the selected object.
Click the value you want to change.
Type the new property value and press Enter.
If the value is valid, the setting changes to the new value. Otherwise, an error message appears indicating the source of the error.
Repeat steps 3 to 4 for additional properties that you want to change.
Tip: If you change a property value while the Cognos service is running, you must restart the service before the change is applied to your computer.
You can reset to the default values 
all the property values
for a group or component, or only an individual property value.
You may want to do this if changes you made are not valid or are
no longer appropriate for your environment, or to prepare for an
unattended installation. For more information, see the installation
guide for your Cognos component.
Start Cognos Configuration.
Choose what values to reset:
To reset all the property values for one group or component, in the Explorer window, click the group or component.
To reset the value of one property, in the Properties window, click the property.
From the Edit menu, click Reset to Default.
Tip: If you reset one or more property values while the Cognos service is running, you must restart the service before the changes are applied to your computer.
