Hi to all ;
I need some clarity regarding OS pasword authentication.
I red many articles still i need some clarity some clarity.
Testing From User A
# useradd -m -g oinstall a
# passwd a
Changing password for user a.
New UNIX password:
BAD PASSWORD: it's WAY too short
Retype new UNIX password:
passwd: all authentication tokens updated successfully.
su - a
[a@testorcl ~]$ export ORACLE_HOME=/u01/app/oracle/product/10.2.0/db_1
$ export PATH=$PATH:$ORACLE_HOME/bin
$ export ORACLE_SID=testdb
$ sqlplus /nolog
SQL*Plus: Release 10.2.0.1.0 - Production on Thu Jan 3 01:33:49 2013
Copyright (c) 1982, 2005, Oracle. All rights reserved.
Testing From user B :
# useradd -m -g dba b
# passwd b
Changing password for user b.
New UNIX password:
BAD PASSWORD: it's WAY too short
Retype new UNIX password:
passwd: all authentication tokens updated successfully.
su - b
Password:
$ export ORACLE_HOME=/u01/app/oracle/product/10.2.0/db_1
$ export PATH=$PATH:$ORACLE_HOME/bin
$ export ORACLE_SID=testdb
$ sqlplus /nolog
sqlplus: error while loading shared libraries: libsqlplus.so: cannot open shared object file: No such file or directory
[b@testorcl ~]$
I need one more clarification ..
Mostly all docs saying In UNIX platform, the special user group is called the DBA group,
but i see user a belongs with oinstall and "user b belongs with dba So user b could n't login."
Which one group is authorized to authenticate "conn /as sysdba"

Thanks to your reply.
Yes you are right user b lacks to invoke sqlplus. so that i set env for both users
$ export ORACLE_HOME=/u01/app/oracle/product/10.2.0/db_1
$ export PATH=$PATH:$ORACLE_HOME/bin
$ export ORACLE_SID=testdb
Given information is not irrelevant & immaterial.
i don't know , what do you expect from me ?
Please see how both users added
Quote:user A with oinstall
user B with dba
my straight ques is
which group is authorized to provide os authentication to os users except oracle user ?
Note : Oracle docs saying who belongs dba group (local DB connctivity)
without username/password verification can login as (connect /as sysdba)
but i checked it provide -ve result (dba group). So that i am asking.
Regards
Sham .G

You seem to want to ignore the FIRST condition which is not in Oracle documentation because it is implicit for any system and product/program: you must FIRST be able to use the program that is you must FIRST have the privileges at OS level to execute the program and any of the libraries it requires.
Your error has nothing to do with Oracle itself, it is the privileges on oracle binaries and libraries at OS level.
So back to your first error: what are the privileges on "libsqlplus.so"?
Regards
Michel

Yes Blackswan now you repeat same answer ,
Here we have problem with dba group and oinstall group.
If i add again user b with oinstall group , user b can connect to sqlplus. (i.e. connect /as sysdba)
problem is oinstall vs dba group only.
Quote:
why OS user with oinstall can access DB ?
why OS user with dba can't access DB ?
How can i troubleshoot ?

Quote:Why we are making these of conversations here ?
I tried to set os authentication to few users.
I wan't to Everything i mean "what i am doing presently"
See here .. what's my current goal ? and please ignore ops$ account.
Everything is here. I want to explain clearly
why os account without dba group i.e . why i am getting error.
I have responsibility what i did ? Simply i can't say to my XXXXXX
"Problem Exists Between Keyboard And Chair "
SQL> create user ops$sam identified externally;
User created.
SQL> grant connect to ops$sam;
Grant succeeded.
useradd -m -g oinstall sam
# passwd sam
Changing password for user sam.
New UNIX password:
Retype new UNIX password:
passwd: all authentication tokens updated successfully.
# su - sam
$ export ORACLE_HOME=/u01/app/oracle/product/10.2.0/db_1
$ export PATH=$PATH:$ORACLE_HOME/bin
$ export ORACLE_SID=testdb
$ sqlplus /

I don't understand what you want to show.
Once more, answer my second question.
I'm not under pressure, I can wait as long as long as you don't answer and don't explain what your posts mean.
Regards
Michel
