如何使用Oracle ODBC网关通过ODBC将Oracle连接到PostgreSQL？

我想从运行Oracle自定义Linux风格的服务器上的Oracle实例运行openSUSE的服务器上的PostgreSQL实例中进行选择。我想使用Oracle ODBC网关执行此操作。过去我成功完成了这个任务，并且继续使用相同的Oracle框和其他SUSE/Postgres框来完成此操作。如何使用Oracle ODBC网关通过ODBC将Oracle连接到PostgreSQL？

在SUSE我的ODBC管理器（Postgres的）侧是：unixODBC的

我ODBC.INI是：

[postgresql] 
Description   = Test to Postgres 
Driver    = /usr/lib64/psqlodbcw.so 
Trace    = Yes 
TraceFile   = sql.log 
Database   = host 
Servername   = localhost 
UserName   = ***** 
Password   = ***** 
Port    = 5432 
Protocol   = 
ReadOnly   = Yes 
RowVersioning  = No 
ShowSystemTables = No 
ShowOidColumn  = No 
FakeOidIndex  = No 
ConnSettings  =

我ODBCINST.INI是

[postgresql] 
    Description    = Postgresql driver for Linux 
Driver   = /usr/lib64/psqlodbcw.so 
UsageCount    = 1

我的tnsnames.ora （省略其他ODBC项）是：

# tnsnames.ora Network Configuration File: /opt/oracle/product/11gR1/db/network/admin/tnsnames.ora 
# Generated by Oracle configuration tools. 

LISTENER_ORCL = 
    (ADDRESS = (PROTOCOL = TCP)(HOST = dbs1)(PORT = 1522)) 

ORCL = 
    (DESCRIPTION = 
    (ADDRESS = (PROTOCOL = TCP)(HOST = dbs1)(PORT = 1522)) 
    (CONNECT_DATA = 
     (SERVER = DEDICATED) 
     (SERVICE_NAME = orcl) 
    ) 
) 

ODBC_SERVER123= 
    (DESCRIPTION= 
    (ADDRESS= 
     (PROTOCOL=TCP) 
     (HOST=dbs1) 
     (PORT=1522) 
    ) 
    (CONNECT_DATA= 
     (SID=server123) 
    ) 
    (HS=OK) 
)

我的listener.ora（省略其他SID_DESC项）为：

# listener.ora Network Configuration File: /opt/oracle/product/11gR1/db/network/admin/listener.ora 
# Generated by Oracle configuration tools. 

LISTENER = 
     (DESCRIPTION_LIST = 
       (DESCRIPTION = 
         (ADDRESS_LIST= 
           (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1522)) 
           (ADDRESS = (PROTOCOL = TCP)(HOST = dbs1)(PORT = 1522)) 
         ) 
       ) 
     ) 

ADR_BASE_LISTENER = /opt/oracle 

SID_LIST_LISTENER= 
     (SID_LIST= 
       (SID_DESC= 
         (SID_NAME=server123) 
         (ORACLE_HOME=/opt/oracle/product/11gR1/db) 
         (PROGRAM=dg4odbc) 
         (ENVS=LD_LIBRARY_PATH=/usr/lib64:/opt/oracle/product/11gR1/db/lib) 
       ) 
     ) 

TRACE_LEVEL_LISTENER = 0 
LOGGING_LISTENER = off

而且，这里是位于$ ORACLE_HOME/HS /管理的inithost123.ora文件：

# 
# HS init parameters 
# 
HS_FDS_CONNECT_INFO = server123 
HS_FDS_TRACE_LEVEL = 0 
#HS_FDS_TRACE_LEVEL=DEBUG 
HS_FDS_SHAREABLE_NAME = /usr/lib64/libodbc.so 

HS_FDS_SUPPORT_STATISTICS = FALSE 

HS_LANGUAGE=AMERICAN_AMERICA.WE8ISO8859P1 
#HS_LANGUAGE=AMERICAN_AMERICA.US7ASCII 
HS_FDS_TIMESTAMP_MAPPING = "TIMESTAMP(6)" 
HS_FDS_FETCH_ROWS=1 
HS_FDS_SQLLEN_INTERPRETATION=32 

# 
# ODBC specific environment variables 
# 
set ODBCINI=/etc/unixODBC/odbc.ini 

# 
# Environment variables required for the non-Oracle system 
# 
#set <envvar>=<value>

和公正的好措施，我的sqlnet.ora是：

：

# sqlnet.ora Network Configuration File: /opt/oracle/product/11gR1/db/network/admin/sqlnet.ora 
# Generated by Oracle configuration tools. 

NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT) 

ADR_BASE = /opt/oracle

我用下面加一个网关连接oracle的方

CREATE DATABASE LINK ODBC_SERVER123 CONNECT TO "*****" IDENTIFIED BY "*****" USING 'ODBC_SERVER123';

当我尝试执行我的选择我收到以下错误：

[SQL] select * from "legit_view"@ODBC_SERVER123 
[Err] ORA-28500: connection from ORACLE to a non-Oracle system returned this message: 
[unixODBC][Driver Manager]Data source name not found, and no default driver specified {IM002} 
ORA-02063: preceding 2 lines from ODBC_SERVER123

我能成功地测试ODBC本地的SUSE/Postgres的盒子ISQL：

>isql -v postgresql ***** ***** 
+---------------------------------------+ 
| Connected!       | 
|          | 
| sql-statement       | 
| help [tablename]      | 
| quit         | 
|          | 
+---------------------------------------+ 
SQL>

哪一步有我忘记了？

两件事。 1.我认为驱动程序应该是odbc.ini（odbcinst.ini中的标题）中的“postgresql”，并且2.可以使用命令行工具“isql”来测试您的unixodbc连接。 – 2013-02-22 18:07:35

您的odbc.ini文件必须位于远程盒子上！也就是说，发起查询的那个人。在上面的例子中就是Oracle盒子。这是一个必须在Oracle（远程）框中输入的条目：

[server123] 
Driver = /usr/lib64/psqlodbcw.so 
Description = ODBC to PostgreSQL on Server 123 
Trace = No 
Tracefile = /var/log/sql_host_123.log 
Servername = ip.address.for.123 
Username = ***** 
Password = ***** 
Port = 5432 
Protocol = 6.4 
Database = host 
QuotedId = Yes 
ReadOnly   = No 
RowVersioning  = No 
ShowSystemTables = No 
ShowOidColumn  = No 
FakeOidIndex  = No
