Oracle 透明网关连接MySQL

Oracle透明网关连接MySQL
连接器下载:http://cdn.mysql.com/Downloads/Connector-ODBC/5.2/mysql-connector-odbc-5.2.6-1.el6.i686.rpm

1.配置unixODBC
/etc/odbc.ini
[mysql]
Driver =/usr/lib/libmyodbc5w.so
Server =192.168.1.50
User =mysql
Password=mysql
Port =3306
database=edmond
Charset =GBK

使用isql测试

2.配置HS
编辑$ORACLE_HOME/hs/admin/initmysql.ora
其中mysql是sid

HS_FDS_CONNECT_INFO = mysql
HS_FDS_TRACE_LEVEL = debug
HS_FDS_SHAREABLE_NAME = libodbc.so
HS_LANGUAGE=AMERICAN_AMERICA.ZHS16GBK
set ODBCINI=/etc/odbc.ini

语言这行不能缺少，否则报错。

3.配置tns
mysql =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.50)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = mysql)
)
(HS = OK)
)

4.配置监听器
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = mysql)
(ORACLE_HOME = /home/lihuilin/dev/app/lihuilin/product/11.2.0/dbhome_1)
(SID_NAME = mysql)
(PROGRAM = dg4odbc)
(ENVS="LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib")
)
)

LISTENER =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(ADDRESS = (PROTOCOL = TCP)(HOST = lihuilin.home)(PORT = 1521))
)

ADR_BASE_LISTENER = /home/lihuilin/dev/app/lihuilin

5.创建db link

在MySQL创建测试表
create table t(a varchar(20) primary key) engine=innodb,charset =gbk;
insert into t values('透明');
commit;

查看结果:

如果前台报错如下所示
ERROR at line 1:
ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
[

$ORACLE_HOME/hs/log的后台日志报错如下:
hgopoer, line 233: got native error 0 and sqlstate I; message follows...
[
Exiting hgopoer, rc=0 at 2014/03/04-21:40:18

Entered hgoexit at 2014/03/04-21:40:18

有两个可能
1.HS_LANGUAGE没有配置
2.HS_LANGUAGE和MySQL的字符集不匹配
