linux上配置unix odbc连接oracle数据库

oracle10g前，oracle并不提供unix/linux下的odbc驱动，用的最为广泛的是unixodbc，unixodbc的配置不算复杂，但是如果不顺利的话也会遇到一些问题。

今天成功安装配置了unixodbc把步骤总结一下供参考。
unixodbc可以在官方站点上下载。

以下是测试及配置步骤:

首先你需要安装oracle客户端，并且确认网络可达。

1.使用isql进行测试

[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 *
* -v verbose. *
* -lx set locale to x *
* --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 *
* last line which must be blank. *

**********************************************

[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

ava =
  (description =
    (address_list =
      (address = (protocol = tcp)(host = 172.16.18.21)(port = 1521))
    )
    (connect_data =
      (sid = ava)
    )
  )

6.测试

[root@magic admin]# isql test -v
+---------------------------------------+
| connected!                            |
|                                       |
| sql-statement                         |
| help [tablename]                      |
| quit                                  |
|                                       |
+---------------------------------------+

7.启动ldap



[root@magic admin]# /usr/local/libexec/slapd -d 5 -f /home/eygle/openldap/slapd.conf

@(#) $openldap: slapd 2.2.17 (dec 29 2004 20:45:12) $
