IBM Tivoli Composite Application Manager for Application Diagnostics, Version 7.1.0.1
Rebuilding the HP-UX kernel
The maxdsiz and maxdsiz_64bit kernel parameters limit the data segment size of a process in HP-UX. In order to generate a Java heap dump, the parameters must be set to at least 1.6 times the size of the Java heap size in the application server.
To configure HP-UX to provide a Java heap dump perform the following procedure:
- Use kmtune to set the parameters maxdsiz and maxdsiz_64bit to at least 1.6 times the size of the Java heap size in the application server.
- Rebuild the kernel.
- Reboot the node.
Refer to the HP-UX documentation for details on how to configure the kernel memory parameters.
