Creating larger or additional swap file

HPE recommends that the swap file size must be equal to the physical memory size, for each processor that runs the Java virtual machine (JVM). If you plan to run multiple large processes in the same processor, you might need to create additional swap files because processes running in the same processor share the same swap file.

Your system administrator can use the NSKCOM tool to create additional swap files.

To add swap files, you must log on to your NonStop operating system as a super.super user. Then, from the Guardian TACL prompt, run the NSKCOM tool. From the NSKCOM tool, use the help add and help start commands to get more information. For further information, see Kernel-Managed Swap Facility (KMSF) Manual.

NOTE:

When using the large Java heap feature provided by NSJ 11, HPE recommends that a contiguous block of Kernel-managed swap space that is at least greater than the Java heap size be available.
