Heapdumps are generated when the Java heap is exhausted by default. They can
also be configured so that they are generated when a user sends a specific signal to
the JVM.
To enable a heapdump, refer to the documentation on JVM parameters for the
server in “Edit Performance Configuration Settings” on page 123.
For more information about heapdumps, refer to the IBM JDK 6.0: Java Diagnostics
Guide.
Monitoring Operations
The Operations functions enable you to monitor the operational status of Sterling
B2B Integrator, its components and services, current threads and system logging,
and to troubleshoot system problems.
Managing System Logs
Sterling B2B Integrator comprises multiple components, including software
applications such as archive tools, Web servers, and database servers. To monitor
the activities of each component, Sterling B2B Integrator generates log files based
on the system's monitoring activity. These log files are one of the tools that enable
you to monitor the way the system operates.
Each operations server on a host has its own operations log file. Log files are
created in the logs directory of the installation directory. To prevent the system log
files from taking up excessive storage space and main memory, Sterling B2B
Integrator generates a log file only when a component runs. This in turn improves
the performance of Sterling B2B Integrator.
Each open log file is closed once every 24 hours (usually at midnight), and a new
file is created. When moving into or out of Daylight Savings Time (DST), you must
stop and restart both Sterling B2B Integrator and its database to ensure that log
files are created with the correct timestamp.
Log files are allowed to grow only up to a maximum size. If a log file reaches its
maximum size, it is closed and another file is created. There is a limit to the
number of log files that can exist simultaneously. If this limit is exceeded, the old
logs files are automatically deleted. If the Sterling B2B Integrator Dashboard
interface links to a deleted log file (which will display a blank page), click the link
to a newer log file.
Note: If you are working in a clustered environment, the log information that is
displayed is determined by the node you select from the Select Node list.
