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:

  1. 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.

  2. Rebuild the kernel.

  3. Reboot the node.

    Refer to the HP-UX documentation for details on how to configure the kernel memory parameters.
