Question

我从Oracle尝试此查询：

select * from "a_table"@Postgres;

以下是我收到的错误消息：

ORA-28545: error diagnosed by Net8 when connecting to an agent
Unable to retrieve text of NETWORK/NCR message 65535
ORA-02063: précédant 2 lines de RECORD
28545. 0000 -  "error diagnosed by Net8 when connecting to an agent"
*Cause:    An attempt to call an external procedure or to issue SQL
       to a non-Oracle system on a Heterogeneous Services database link
       failed at connection initialization.  The error diagnosed
       by Net8 NCR software is reported separately.
*Action:   Refer to the Net8 NCRO error message.  If this isn't clear,
       check connection administrative setup in tnsnames.ora
       and listener.ora for the service associated with the
       Heterogeneous Services database link being used, or with
       'extproc_connection_data' for an external procedure call.
Erreur à la ligne 1, colonne 25

这是 tnsnames.ora

Postgres =
   (DESCRIPTION =
     (ADDRESS_LIST =
     (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
   )
   (CONNECT_DATA =
     (SID = RECORD)
   )
   (HS=OK)
  )

这是 listener.ora

LISTENER_HS =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1525))
        (ADDRESS = (PROTOCOL = IPC)(KEY = PNPKEY))
      )
    )
  )

SID_LIST_LISTENER_HS =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = RECORD)
      (ORACLE_HOME = /oracle/product/10.2.0)
      (PROGRAM = hsodbc)
      (ENVS = "LD_LIBRARY_PATH=/oracle/product/10.2.0/lib32:/oracle/product/10.2.0/hs/lib32:/user/lib")
    )
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = /oracle/product/10.2.0)
      (PROGRAM = extproc)
    )
  )

启动监听器后请注意，这是输出

$ lsnrctl status LISTENER_HS

此处 initPostgres.ora

HS_FDS_CONNECT_INFO = Postgres
HS_FDS_TRACE_LEVEL = DEBUG
HS_FDS_TRACE_FILE_NAME = /oracle/product/10.2.0/hs/log/postgres.trc
HS_FDS_SHAREABLE_NAME = /usr/lib/psqlodbc.so

set ODBCINI= /etc/odbc.ini

/oracle/product/10.2.0/hs/log/record.trc为空。

我错过了什么？

Oracle 10gR2
Linux RedHat 64bit

Postgresql 8.3
Linux RedHat 64bit

修改当我尝试手动检查ODBC驱动程序是否启动并运行时，这就是我得到的：

$ isql postgres USER PASS -v
[01000][unixODBC][Driver Manager]Can't open lib '/usr/lib/psqlodbc.so' : /usr/lib/psqlodbc.so: Ne peut ouvrir le fichier d'objet partagé: Aucun fichier ou répertoire de ce type
[ISQL]ERROR: Could not SQLConnect

Answer 1

我在Oracle论坛上问了同样的问题，我收到了回复。

简单地说，我不能在Linux 64bit上使用hsodbc，因为Linux 32bit没有端口。相反，我必须使用DG4ODBC与我的Oracle 10.2.0.3不兼容。然后我的替代方案是：

安装Database Gateway for ODBC 11.2.0.3
从Oracle 10.2.0.3迁移到Oracle 10.2.0.4或更高版本
或应用补丁5965763

详细的回复是here。

如何在Linux RedHat 64bit上将Oracle 10gR2上的dblink设置为Linux RedHat 64bit上的Postgresql 8.3？
