When the dashboard data provider has
been enabled on the Tivoli® Enterprise Portal Server,
you can use monitoring dashboards in the Dashboard
Application Services Hub console.
In larger environments, it is possible for the Tivoli Enterprise Portal Server extended
services (TEPS/e) Java process to run out of memory when large amounts
of data are passed to the Dashboard
Application Services Hub. You
can increase the maximum heap size of the TEPS/e JRE to improve server
response time and better accommodate a larger monitored environment.
Before you begin
The memory required by the TEPS/e depends on the size of the
monitoring environment and on the Java heap size parameters. The default
maximum Java heap size is 1500 MB, which is appropriate for 32-bit
systems. On 64-bit systems, if you encounter
"out of memory" exceptions,
you can increase the maximum heap size of the TEPS/e JRE to values
greater than 1500 MB to allow more memory usage and accommodate a
larger monitored environment.
About this task
Complete the following steps on the computer where the portal
server is installed to adjust the TEPS/e maximum heap size.
Procedure
- At the command prompt, change to the bin directory of your Tivoli Monitoring installation:
install_dir\cnpsj\profiles\ITMProfile\bin
install_dir/platform/iw/profiles/ITMProfile/bin
- Enter the following command to start the eWAS console:
- wsadmin.bat
- wsadmin.sh
- At the wsadmin prompt, enter the following command: $AdminConfig
modify [$AdminConfig list JavaVirtualMachine] "{maximumHeapSize 2000}"
- Enter the following command to save your changes: $AdminConfig
save
- Enter the following command to exit: quit
What to do next
Restart the portal server. If you continue to encounter
"out
of memory" exceptions, try increasing the maximum heap size again.
