H06.13 Software Installation and Upgrade Guide

KMSF swap files need to be larger than in G-series RVUs. The best practice is to monitor swap file

usage. See the Kernel-Managed Swap Facility (KMSF) Manual for information on configuring swap

file space.

To check the size of the configured swap files for each processor:

1. At a TACL prompt, start NSKCOM:

$SYSTEM STARTUP 5> nskcom

NSKCOM - T5838H01 BASE (01OCT04) - Apr 15 2005

$SYSTEM.SYSTEM.ZSYSCFG

KMS.SWAPFILE = 0 $SYSTEM.ZSYSSWAP.SWAP00

KMS.SWAPFILE = 1 $SYSTEM.ZSYSSWAP.SWAP01

KMS.SWAPFILE = 2 $SYSTEM.ZSYSSWAP.SWAP02

KMS.SWAPFILE = 3 $SYSTEM.ZSYSSWAP.SWAP03

2. Issue the STATUS SWAPFILE * command to display the peak pages reserved so that you

can compare that information to the total amount of swap space available.

$SYSTEM TOOLS 50> nskcom STATUS SWAPFILE *

NSKCOM - T5838H01 BASE (01OCT04) - Jun 17 2005

$SYSTEM.SYSTEM.ZSYSCFG

KMS.SWAPFILE = 0 $SYSTEM.ZSYSSWAP.SWAP00

KMS.SWAPFILE = 1 $SYSTEM.ZSYSSWAP.SWAP01

KMS.SWAPFILE = 2 $SYSTEM.ZSYSSWAP.SWAP02

KMS.SWAPFILE = 3 $SYSTEM.ZSYSSWAP.SWAP03
