首先你需要安裝Oracle客戶端，并且確認網絡可達。

1.使用isql進行測試

[root@magic root]# isql
**********************************************
* unixODBC - isql *
**********************************************
* Syntax *
* *
* isql DSN [UID [PWD]] [options] *
* *
* Options *
* *
* -b batch.(no prompting etc) *
* -dx delimit columns with x *
* -x0xXX delimit columns with XX, where *
* x is in hex, ie 0x09 is tab *
* -w wrap results in an HTML table *
* -c column names on first row. *
* (only used when -d) *
* -mn limit column display width to n *

* --version version *
* *
* Notes *
* *
* isql supports redirection and piping *
* for batch processing. *
* *
* Examples *
* *
* cat My.sql | isql WebDB MyID MyPWD -w *
* *
* Each line in My.sql must contain *
* exactly 1 SQL command except for the *

[root@magic root]# isql --versio
unixODBC 2.2.10
[root@magic root]# which isql
/usr/bin/isql

2./etc/odbc.ini文件配置

[ODBC Data Sources]
test = Oracle ODBC Driver DSN

[default]
Driver = /usr/local/easysoft/oracle/libesoracle.so

[test]
Driver = /usr/local/easysoft/oracle/libesoracle.so

Description = Oracle
server = 172.16.1.21
ServerType = Oracle
Port = 1521
User = username
Password = password
Database = ava
SID = ava
METADATA_ID = 0
ENABLE_USER_CATALOG = 1
ENABLE_SYNONYMS = 1

[default]
Driver = /usr/local/easysoft/oracle/libesoracle.so

3. /etc/odbcinst.ini 文件配置

;
; odbcinst.ini
;

[test]
Description=ODBC for ORACLE
Driver = /usr/local/easysoft/oracle/libesoracle.so

[ODBC]
Trace=1
Debug=1
Pooling=No

4.sqlnet.ora文件配置

NAMES.DIRECTORY_PATH= (TNSNAMES, ONAMES, HOSTNAME)

5.tnsnames.ora文件配置
