Problemm with dba group vs oinstall group
JhilJan 4 2013 — edited Jan 5 2013Hi to all ;
This is related to oracle as well as some os related security problems. please clarify it.
I tried but couldn't solve it All information's given here ..
Testing from user 'A'
+# useradd -m -g oinstall a+
+# passwd a+
Changing password for user a.
New UNIX password:
BAD PASSWORD: its 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+

Testing From user 'b' :
+# useradd -m -g dba b+
+# passwd b+
Changing password for user b.
New UNIX password:
BAD PASSWORD: its 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
*>> From oracle user finding libsqlplus.so >>*
*[oracle@testorcl ~]$*
*$ find / -name libsqlplus\* -ls 2>/dev/null*

SQLPLUS LOCATION with associated group
+$ ls -l $ORACLE_HOME+
drwxr-x--- 9 oracle oinstall 4096 Dec 24 03:28 sqlplus
Please Note :
USER 'a' belongs oinstall group.
USER 'b' belongs dba group.
My questions are :
*1.why OS user can access database with oinstall group ?*
*2.why OS user can't access database with dba group ?*
Note: This is concept of oracle
**To connect as sysdba using OS Authe*ntication ; UNIX OS user must be a part of OSDBA (dba) group.*
Once the user is part of OSDBA group.
but in dba group with os user 'b' , can't connect sqlplus , what's the real problem here ?
