swlist/swinstall has no output

Li Hao — Fri, 22 Dec 2006 04:02:31 GMT

I have one HP UX 11.23 server which I would like to apply the Sep 2006 Quality pack patch. but when I try to run the swlist or swinstall command, it just return with no output, no error at all, I guess it was the hosts/dns lookup problem somewhere, but I just can not find what is the root cause.

I have check the /var/adm/sw/swagentd.log, it sometime shows a dns lookup error. but most of time is also don't have any error.

HI,
and welcome to the forums.
Kill then Restart your swagent:
kill -15 $(UNIX95=1 ps -C swagentd -o pid=)
/usr/sbin/swagentd -r

Correct any network problems.
Check /etc/hosts, /etc/nsswitch.conf and others.
Ensure you are pointing to a correct software location.

Use SAM

Hi (again),
forgot to add the test:
swlist -R

I have clean up /etc/hosts file, I can look up my host name correctly, verified using ping.

try to stop the swagentd using /sbin/init.d/swagentd stop, then start it again, same result, no output, just return.

I try to kill the swagentd pid, then restart using /usr/sbin/swagentd -r, same result.

all command swlist -l bundle, or swlist -R or swlist, swinstall has no ouput. using SAM to check installed software also just fresh the screen with no result.

nsswitch.conf point to DNS as first, /etc/hosts as secondary.

Hi,
thanks for the feedback.
Can you please check the /var/adm/sw/products directory for products/patches etc.

Especially the index file
ll /var/adm/sw/products | grep -i index

Ensure you are running:
/usr/sbin/swlist

our nsswitch.conf:
# cat /etc/nsswitch.conf
hosts: files [NOTFOUND=continue UNAVAIL=continue] dns [NOTFOUND=return UNAVAIL=continue TRYAGAIN=return]

As long as you have a continue if the dns is not found.

Since commands are returning no output can you verify that their size is not zero?

# ll /usr/sbin/sw*

Most of the SD-UX commands (swlist, swinstall) are hard linked to each other and setuid to root.

Make sure your nsswitch.conf file has the hosts line looking at files first, then DNS (as mentioned above). Verify that your resolver is looking at the /etc/hosts file first with this command:

nsquery hosts $(hostname)

Then, did a well-meaning root user 'cleanup' the /var directory by removing some /var/adm/sw directories? If so, your system is damaged and the missing directories must be restored from your backup.

It turn out the /usr/sbin/sw* files are size 0. the files are somehow damaged during my last install of a package. I restored the file from another server, now it works.
