hello!I have a strange question:
in red hat AS 4,when I su other users ,for example:
[root@wlxxb ~]# su oracle
[oracle@wlxxb root]$ ll
ls: error while loading shared libraries: librt.so.1: cannot open shared objectfile: No such file or directory
[oracle@wlxxb root]$ top
top: error while loading shared libraries: libc.so.6: cannot open shared objectfile: No such file or directory
[oracle@wlxxb root]$ ls
ls: error while loading shared libraries: librt.so.1: cannot open shared objectfile: No such file or directory

what I to do to solve this problem?

whats the output for cat /etc/passwd | grep oracle

and in future please give a relevant title for the thread...

My guess is that something is not in the PATH. Maybe use su - oracle will help as it uses the environment of the new user instead of the environment of the 'old' user.

It is however, in my opinion, a bit strange that a library can not be found.

[root@wlxxb ~]# cat /etc/passwd | grep oracle
oracle:x:500:500::/home/oracle:/bin/bash

[root@wlxxb ~]# su - oracle
[oracle@wlxxb ~]$ ll
ls: error while loading shared libraries: librt.so.1: cannot open shared objectfile: No such file or directory
[oracle@wlxxb ~]$

What happens if you use the command such as 'top' in root? I am assuming it works fine?

DragonM15

really it works fine

what is the output of

ldd $(which su)

[root@wlxxb ~]# (which su)
/bin/su

[root@wlxxb ~]# su oracle
[oracle@wlxxb root]$ ll
ls: error while loading shared libraries: librt.so.1: cannot open shared objectfile: No such file or directory
[oracle@wlxxb root]$ locate librt.so.1
locate: error while loading shared libraries: libc.so.6: cannot open shared object file: No such file or directory
[oracle@wlxxb root]$ exit
exit
You have new mail in /var/spool/mail/root
[root@wlxxb ~]# locate librt.so.1
/lib/librt.so.1
[root@wlxxb ~]#

my fault, .... actually ldd is the part of the command. plese provide the output of `ldd $(which su)` and not just `which su` while you are logged in as oracle.

you got this issue only for the oracle user or for all users different than root?
