Oracle11.2g post-installation problem on Oracle Linux kernel

Question

After installation of Oracle 11.2g in silent mode on the Oracle Linux kernel, I have the following error:

[u01/app/oracle/product/11/bin] $ sqlplus
sqlplus error while loading shared libraries: libsqlplus.so: cannot open shared 
object file: No such file or directory

However, the shared object seems to be setup correctly:

[/u01/app/oracle/product/11/lib] $ ls -lrt /u01/app/oracle/product/11/lib | grep sqlplus 
-rw-r--r--. 1 oracle oinstall 1475820 Aug 1 2009 libsqlplus.a 
-rwxr-xr-x. 1 oracle oinstall 1218075 Aug 1 2009 libsqlplus.so

The user is oracle:

[oracle ~]$ id oracle 
uid=501(oracle) gid=501(oinstall) groups=501(oinstall),502(dba)

The environment variables are:

[oracle ~]$ env 
USER=oracle 
LD_LIBRARY_PATH=/u01/app/oracle/product/11/lib 
ORACLE_SID=orcl 
ORACLE_BASE=/u01/app/oracle 
PATH=/usr/lib/qt-3.3/bin:/usr/local/bin
 :/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin: /home/oracle/bin
 :/u01/app/oracle/product/11/bin 
HOME=/home/oracle 
ORACLE_HOME=/u01/app/oracle/product/11 

kernel version:

2.6.32-300.3.1.el6uek.i686

Any idea why SQLPlus is complaining about libsqlplus.so?

Answer 1

Make libclntsh executable:

chmod +rx /u01/app/oracle/product/11/lib/libclntsh*

Then check the above commented ldd command again.

Answer 2

You should be searching for libclntsh.so.11.1 in /u01/app/oracle/product/11/lib ,

• Philᵀᴹ: Are you sure the silent install completed? The library should also be in $ORACLE_HOME/lib. Check the silent install log file.
• user1182411: @phil libclntsh.so.11.1 found after mod changed
• user1182411: @phil found one silent install log file called : silentInstall2012-01-24_06-14-37PM.log actually full of errors. But now the $ sqlplus /nolog worked, but denied access to sqlplus /as sysdba
• Philᵀᴹ: What's the error message when you "sqlplus / as sysdba" ?
• user1182411: @phil ERROR: ORA-12547: TNS:lost contact but it gave me the prompt to log and no user name and password already set in the response file match
