Performance Maintenance

This section includes topics about using IBM® Cognos® Analytics and other tools and metrics to maintain the performance of your IBM Cognos Analytics environment.

System Performance Metrics
IBM Cognos Analytics provides system metrics that you can use to monitor the health of the entire system and of each server, dispatcher, and service. You can also set the thresholds for the metric scores. Some examples of system performance metrics are the number of sessions in your system, how long a report is in a queue, how long a Java™ Virtual Machine (JVM) has been running, and the number of requests and processes in the system.
Enabling Only Services That are Required
If some IBM Cognos Analytics services are not required in your environment, you can disable them to improve the performance of other services.
Tuning a IBM Db2 Content Store
If you use a Db2 database for the content store , you can take steps to improve the speed with which requests are processed.
Adjusting the memory resources for the IBM Cognos service
To improve performance in a distributed environment, you can change the amount of resources that the IBM Cognos service uses.
Reduce Delivery Time for Reports in a Network
Reports that are distributed globally take longer to open in remote locations than to open locally. In addition, HTML reports take longer than PDF reports to open because more requests are processed for HTML reports.
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.
