Siebel Database Configuration Wizard fails with "Segmentation fault"

Using odbcsql utility, ODBC connection fails with "Segmentation fault".

During a fresh install of a Siebel CRM environment on Linux OS, while running the Siebel Database Configuration Wizard for Siebel database installation, the screen disappears after entering Database user name and password (SADMIN/SADMIN).

Cause

ORACLE_HOME environment variable is not set to full pathname of the Oracle system home directory.

Solution
Trace odbcsql utility with "strace" Linux to see which libraries are loaded.
$ strace –fo

odbcsql

In the generated trace file last "open" command is:

open("./oracore/zoneinfo/timezlrg.dat", O_RDONLY) = -1 ENOENT (No such file or directory)--- SIGSEGV (Segmentation fault) @ 0 (0) ---The correct location for timezlrg.dat file is: “$ORACLE_HOME/oracore/zoneinfo/”

To set ORACLE_HOME variable use the following commands depending on the Unix shell you are using:

sh:
$ ORACLE_HOME=; export ORACLE_HOME
csh:
$ setenv ORACLE_HOME
bash/ksh:
$ export ORACLE_HOME=

Make sure the values are set:

$ env | grep ORACLE_HOME
