The following are known problems and limitations in WebSphere®
Business Monitor until the release of this publication. Check the support
website at:
http://www.ibm.com/software/integration/wbimonitor/support for additional
reported problems.
WebSphere Business Monitor installation validation
The following information describes how to validate the successful
completion of each installation step. The Monitor installation process is
complex and time consuming, so a step by step verification is highly recommended.
Finding a problem at the end of the entire process may necessitate a complete
reinstallation of some portions of the software stack.
Improving performance after deploying database services artifacts
After the deployment of data services artifacts, several indices
are created that cause DB2® to choose poor access plans. You must perform some
steps immediately after the deployment and before you start any of the data-services
component servers to ensure that good access plans are created.
Changing data services parameters to improve performance
Database services support WebSphere Business Monitor through
two data movement services: State to Runtime and Runtime to Historical. These
data movement services are completely independent of each other. Each data
movement service supports one or more business
measures models.
Daylight saving time and network time servers
Daylight saving time and network time servers both affect the current
time on a server machine. In data movement services, timestamps are used to
determine when the servers check for new data and when they perform the data
movement. Changes to the system clock affect the data services components
and their perceived performance.
How timestamps are represented in WebSphere Business Monitor
Because WebSphere Business Monitor uses
multiple databases in its data services component, it is important to understand
how timestamps are transformed by the system between these databases during
the databases replication.
