su - icsadm
/usr/lib/dld.sl: Unresolved symbol: initialize_error_table_r (code) from /usr/local/lib/libkrb5.sl
Abort(coredump)

what does the error mean?and how can i find solutions for that ?

Shalom,

It means that the user profile icsadm probably the .profile file refers to a program that fails and core dumps.

Examine the user profile and see what it runs. Perhaps add a few echo statements so you can find the problem.

It could however be a problem with su. Please check with a different user and report back.

thank you ,Steven E. Protter.
now this is the .profie of icsadm:
# more .profile
PATH=/usr/bin:/etc:/usr/sbin:/usr/ucb:$HOME/bin:/usr/bin/X11:/sbin:.
day=`date +%d`

alias l="ls -l"
alias lf="ls -F"
alias cdl="cd $HOME/log/$day"
alias cdt="cd $HOME/trc/$day"
alias cde="cd $HOME/etc"

set -o vi

PS1="[`hostname`] "'$LOGNAME:''$PWD''>';export PS1

# set DB2 profile
if [ -f /home/db2inst1/sqllib/db2profile ]; then
. /home/db2inst1/sqllib/db2profile
fi

SHLIB_PATH=/home/db2inst1/sqllib/lib32:/opt/sna/lib
export SHLIB_PATH
--------------------
and what echo statement you think can add to the .profile which can help me to find the problem?

Add one before DB2 includes:

echo "check"

# set DB2 profile
if [ -f /home/db2inst1/sqllib/db2profile ]; then
. /home/db2inst1/sqllib/db2profile
fi

Something like:
echo "I got to line XXX"
...
echo "I got to line YYY"

So you can track how far you got by looking at the output.

If you can find the core file, "file core" will tell you the executable.

how can i get the corefile?

Well, it is either in the directory where you did the su or the home directory for icsadm, or somewhere else and you would have to use find(1) to find it.

Shalom,

Make sure the SHLIB_PATH includes /usr/lib and /usr/local/lib

Set it up in the profile before you try to start the database.

The problem could be in the PAM libraries too: the library name /usr/local/lib/libkrb5.sl sounds like it could be refer to Kerberos 5.
If the icsadm user's .profile does not get executed at all, this is likely.

Check /etc/pam.conf and /etc/pam_user.conf and compare them to factory default versions in /usr/newconfig/etc. If there are any differences, try to determine whether the current configuration makes sense in your environment.

Do you have Kerberos authentication in use? If not, this might be a remnant of some previous installation. If yes, find the documentation of your Kerberos authentication software and follow its troubleshooting steps.
