1. Check unixODBC is installed.

$ odbcinst -j

unixODBC 2.2.14

DRIVERS............: /etc/odbcinst.ini

SYSTEM DATA SOURCES: /etc/odbc.ini

FILE DATA SOURCES..: /etc/ODBCDataSources

USER DATA SOURCES..: /home/${UID}/.odbc.ini

sqlULEN Size.......: 8

sqlLEN Size........: 8

sqlSETPOSIROW Size.: 8

If not,please download fromhttp://www.unixodbc.org

2. Install Oracle 11g

...

3. Configure the Oracle ODBC Driver

$ locate libsqora

${ORACLE_HOME}/lib/libsqora.so.11.1

$ ldd ${ORACLE_HOME}/lib/libsqora.so.11.1

ldd: warning: you do not have execution permission for `${ORACLE_HOME}/lib/libsqora.so.11.1'

linux-vdso.so.1 => (0x00007fff54a3a000)

libdl.so.2 => /lib64/libdl.so.2 (0x00007f9fb6fc7000)

libm.so.6 => /lib64/libm.so.6 (0x00007f9fb6d42000)

libaio.so.1 => /lib64/libaio.so.1 (0x00007f9fb3984000)

If there is libodbcinst.so.1 => not found,create a symbolic link from /usr/lib64/libodbcinst.so.1 to /usr/lib64/libodbcinst.so.2

$ cd /usr/lib64

$ sudo ln -s libodbcinst.so.2 libodbcinst.so.1

3. ConfigureOracle ODBC driver

Add following section into/etc/odbcinst.ini

[Oracle11g]

Description = Oracle ODBC driver for Oracle 11g

Driver = ${ORACLE_HOME}/lib/libsqora.so.11.1

Setup =/usr/lib64/liboraodbcS.so # this is not necessary

FileUsage =

CPTimeout =

CPReuse =

Driver Logging = 7

4. Configure Oracle User Data Source

Add following section into ~/.odbc.ini

[ORACLEORCL]

driver = Oracle11g #driver is defined in /etc/odbcinst.ini

server = localhost

port = 1521

ServerName = ORCL # this ID is configured in $ORACLE_HOME/network/admin/tnsnames.ora

UserID = scott

password = tiger

5. Verify isql can work

$ isql OracleORCL
