Increase Asynchronous Timeout in High User Load Environments.

If you have a high user load (over 165 users) and interactive reports are running continuously in a distributed installation, you may want to increase the asynchronous timeout setting to avoid getting error messages. The default is 30000.

To resolve this problem, increase the wait timeout.

Question No. 5

Which of the following is a valid step?

ARemove the default authentication provider.

BEnable anonymous access for selected users, groups, or roles.

CDelete the Everyone group to limit access to the environment for selected users, groups, and roles.

DAdd trusted users, groups, or roles to the System Administrators role, and then remove the Everyone group from the role.

Show Answer

Correct Answer: D

You may not want all users that exist in an authentication source to have access to IBM Cognos software. To secure IBM Cognos software, configure the product so that only users who belong to a specific group or role in your authentication source, or in the Cognos namespace, are allowed access.

We recommend using the Cognos namespace because it contains preconfigured groups and roles that help you to secure IBM Cognos software quickly. One of the preconfigured groups is Everyone.

By default, the group Everyone belongs to several built-in groups and roles in the Cognos namespace.

If you decide to use the Cognos namespace, you must remove the Everyone group from all built-in groups and roles and replace it with groups, roles, or users authorized to access IBM Cognos software.
