Error: Failed to connect to aleph21
Tue Apr 23 09:29:30 EDT 2013 Step aleph21_add_datafiles.bash [ Failed ]

UNIX user aleph could not connect to the Oracle database aleph21 as database user ALEPH_ADMIN.

2. When trying to connect to the database as user ALEPH_ADMIN by means of SQL*Plus the following error message was received:

aleph@aleph-arc(a21_1):> sqlplus $ALEPH_ADMIN

SQL*Plus: Release 11.2.0.3.0 Production on Mon Apr 29 08:24:00 2013

ERROR:
ORA-12547: TNS:lost contact

Cause:
The permissions on the file /exlibris/app/oracle/product/11r2/bin/oracle (the Oracle server binary) are incorrect. In order to allow UNIX users other that oraleph (owner of the Oracle 11.2.0.3 software) to connect to the Oracle database instance aleph21, the Set-User-ID Bit and the Set-Group-Id Bit of the file /exlibris/app/oracle/product/11r2/bin/oracle must be set. This means that the permissions on the file /exlibris/app/oracle/product/11r2/bin/oracle must look as follows (file mode 6751):

-rwsr-s--x /exlibris/app/oracle/product/11r2/bin/oracle

However, the permissions look like this (file mode 755):

-rwxr-xr-x /exlibris/app/oracle/product/11r2/bin/oracle

Resolution:
(1)
Shut down the Oracle database aleph21 (as UNIX user oraleph):

$ sqlplus / as sysdba
SQL> shutdown immediate

(2)
Execute the script root.sh to set the correct the permissions on the files extjob, ..., oradism listed above (as UNIX user root):

$ su - root
# cd /exlibris/app/oracle/product/11r2
# ./root.sh

(3)
Set the correct the permissions on the file /exlibris/app/oracle/product/11r2/bin/oracle (as UNIX user oraleph):

$ chmod 6751 /exlibris/app/oracle/product/11r2/bin/oracle


(4)
Start the Oracle database aleph21 (as UNIX user oraleph):

$ sqlplus / as sysdba
SQL> startup

(5)
Verify that UNIX user aleph can connect to the Oracle database aleph21 as database user ALEPH_ADMIN:

$ su - aleph
$ sqlplus $ALEPH_ADMIN
[...]
Connected to:
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production

(6)
Execute AIK Step 6.3 again.
