abort(coredump) with sam ...

[GRP_2]

Hi,

on a hp-ux 10.20 system, when I start sam and want to go the users area ("Accounts for Users and Groups"), I got the following message :

>>>>> START of error message
UNEXPECTED EXIT: process LANG=C LC_ALL=C /usr/sam/lbin/samx -C -p 12722 -s users /usr/sam/lib//ug.ui exited with a non-zero status

/usr/lib/dld.sl : unresolved symbol : dcnodes(code) from /usr/sam/lbin/samx

sh: 12855 Abort(coredump)
<<< END of error message

What does it mean and resolve my problem?
Thanks in advance.

hi,
are you running any nfs cluster with diskless nodes ?. dcnodes indicate a diskless cluster.
if you don't have that disless cluster setup ,
and you have this error , then you may try
renaming /etc/clients.dc file.
let me know what is the output of
#dcnodes -ls
regards,
U.SivaKumar

hi,
if you don't run a diskless cluster , check this -
#ps -ef | grep dcnodesd
if dcnodesd is running , kill that process.
and start sam again.
regards,

I think your problem is most likely related to problems or corruption of one or more of the following shared libraries /usr/lib/libdc.sl
/usr/lib/libdce.1 /usr/lib/libc.1
/usr/obam/lib/libobam.1
/usr/lib/libm.1
/usr/lib/libdld.1

most likely /usr/lib/libdc.sl

use /var/adm/sw/products/OS-Core/CORE-SHLIBS/INFO to compare chksums etc ... if they don't check out you could copy from similar patches system or replace the lib from the core O/S .... does swinstall also fail ?

fyi : libdc.sl is part of the OS-Core.CORE-SHLIBS fileset.

do make sure you have b/u's before copying things over etc....

other useful info : file core and chatr sam .....

thanks a lot, Alex, file /usr/lib/libdc.sl was effectively wrong ...

2 last questions, please :

1- what's your secret? yes, you're HP enginner but how did you guess which file could be wrong ?

2- how can I verify system directories/files to avoid some hother kind of problems?

thanks a lot !!

There's no secret .... after 5 years supporting hpux you start to see patterns emerging ... that combined with a good internal knowledgebase always helps .... I or you got lucky .... the answer was the most obvious choice ...there probably could have been other reasons but libdc.sl was the obvious candidate.

As to your other question not too sure I guess swlist -a state may help as would a good backup policy ....
