If your IBM Cognos servers operate within a load balancing infrastructure, you can turn off the weighted round robin format of load balancing for the dispatcher. Otherwise, load balancing may be duplicated by the cluster and by IBM Cognos software, which can degrade performance.
You can set the dispatcher property named loadBalancingMode either to weightedRoundRobin or clusterCompatible.

The metric score for each entry is based on the performance of individual child entries. The status that is displayed for each entry is the lowest status of the child entries. For example, if all the metrics for a dispatcher are good, but one service on that dispatcher has a poor metric, the metric score shown for the dispatcher is poor.

Status is one of the following: Available if all components are available Partially available if at least one component is available and at least one component is unavailable or partially unavailable.
Unavailable if all components are unavailable

Grouping dispatchers in configuration folders.
Configuration folders are useful to organize dispatchers if your installation includes many dispatchers. You can group dispatchers so that you can apply the same configuration settings once to all the dispatchers and services in the folder.

Note: You can have more than one dispatcher in your IBM Cognos environment. In such distributed installations one dispatcher is configured for every instance of the Content Manager or Application Tier Components that are installed and configured in your environment.

The Cognos namespace includes predefined objects to help you quickly set up initial security.
You use the predefined objects and other features of the Cognos namespace for ongoing security management.
You can create groups and roles in the Cognos namespace.
Initial access permissions are applied to all predefined objects. You can modify the permissions from the object properties.

The higher you set the logging level, the more it degrades system performance. Normally, you set the level to Minimal or Basic to collect errors, or to Request to collect errors and warnings.

Note: Report validation levels and logging levels Report validation level, Logging level Error: Minimal, Basic Warning: Request
Key Transformation: Trace
Information: Full

Problem(Abstract): Datasource connections not listed in Data server by default Symptom: We can see the datasource in the Admin console but not in the list of data servers.

Cause: This is default behavior.

Resolving the problem
Go to the Administrative Console -> Configuration -> Set properties -> Connections tab.
On the bottom, you will see "Data source capabilities"
Inside that, check the box which says "Allow web-based modeling"
Once you check this, the datasource would be present as data server.

The Presentation service
Transforms generic XML responses from another service into output format, such as HTML or PDF Provides display, navigation, and administration capabilities in IBM Cognos Connection

Incorrect Answers:
A: The Report service manages interactive requests to run reports and provides output for a user in IBM Cognos Connection or a studio.
B: The Delivery service sends emails to an external SMTP server on behalf of other services, such as the report service, job service, agent service, or data integration service
D: The Content Manager service: Performs object manipulation functions in the content store, such as add, query, update, delete, move, and copy Performs content store management functions, such as import and export

Unlike routing keywords, the order in which the routing rules are listed affects how they are applied.
A rule is matched when properties associated with the package or the group or role involved in the request satisfy the criteria of the rule. The rules are evaluated in order until the first one is matched, and the request is routed to the server group named by the first rule that was matched. You can change the order of the rules by clicking Modify the sequence.

You can disable the Anonymous user account by changing the configuration parameters in the configuration tool.
This entry represents a user account shared by members of the general public who can access IBM Cognos software without being prompted for authentication. For example, this type of access is useful when distributing an online catalog. Anonymous users can see only those entries for which access permissions are not set, or are set specifically for this account or for the Everyone group.

Incorrect Answers:
A: The built-in entries include the Anonymous user account, the groups All Authenticated Users and Everyone, and the role System Administrators. You cannot delete the built-in entries. They appear in both secured and non-secured environments.
