Check the Status of the Spooler Collector

3. Use the SCF STATUS TAPE, DETAIL command to display the current state of the

tape drive.

4. If the status of the tape drive is stopped or not ready, start the tape drive and put

the tape drive online.

Check the Status of the Spooler Collector

Check that the spooler collector is active and not 100 percent full.

At a TACL prompt, start SPOOLCOM and issue a COLLECT, STATUS command. For

example:

1> spoolcom $spls; collect, status

COLLECT STATE FLAGS CPU PRI UNIT DATA FILE %FULL

$S ACTIVE 3 , 1 154 4 $OPS0.SPL.DATA 44

Check for Sufficient Swap File Space

You must ensure that you have configured kernel-managed swap files of sufficient size

for all your system and application software processes. The optimal amount of swap

space varies, depending on the configuration of your system. You must be a

super-group user (255, n) in order to change the KMSF configuration by adding,

altering, stopping, or deleting swap space. Only one super-group user at a time can

use NSKCOM to change the configuration.

KMSF swap files need to be larger than on G-series. 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
