After installing and configuring IBM Cognos 8 BI, one dispatcher is available on each computer by default. Each dispatcher has a set of associated services, listed in the following table.
Service |
Purpose |
Agent service |
Runs agents. If the conditions for an agent are met when the agent runs, the agent service asks the monitor service to run the tasks. |
Batch report service |
Manages background requests to run reports and provides output on behalf of the monitor service. |
Content Manager service |
|
Data movement service |
Manages the execution of data movement tasks in IBM Cognos 8. Data movement tasks, such as Builds and JobStreams, are created in Data Manager Designer and published to IBM Cognos 8. |
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 |
Event management service |
Creates, schedules, and manages event objects that represent reports, jobs, agents, content store maintenance, deployment imports and exports, and metrics |
Job service |
Runs jobs by signaling the monitor service to run job steps in the background. Steps include reports, other jobs, import, exports, and so on. |
Log service |
Records log messages generated by the dispatcher and other services. The log service can be configured to record log information in a file, a database, a remote log server, Windows Event Viewer, or a UNIX system log. The log information can then be analyzed by customers or by Cognos Software Services, including:
