Oracle HS（12c）

Question

我正在尝试从12c数据库设置HS，最终将数据发送到远程MySQL服务器。

我已经安装了odbc驱动程序;

root ~ # rpm -ivh mysql-connector-odbc-5.3.4-1.el6.x86_64.rpm

这是我的listener.ora文件;

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = ap-ora-records-test.ap.local)(PORT = 1521))
    )
  )

这是我的tnsnames.ora文件;

RECORDSDB =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = ap-ora-records-test.ap.local)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = recordsdb.ap.local)
    )
  )

MYSQL =
  (DESCRIPTION=
    (ADDRESS=(PROTOCOL=tcp)(HOST=ap-ora-records-test.ap.local)(PORT=1521))
    (CONNECT_DATA=(SID=MYSQL))
    (HS=OK)
  )

我连接到数据库，并创建了数据库链接;

SQL> CREATE DATABASE LINK MYSQL
  2  CONNECT TO "root" IDENTIFIED BY "removed"
  3  USING 'mysql';

重新启动lsnrctl;

./bin/lsnrctl reload
./bin/lsnrctl stop
./bin/lsnrctl start
./bin/lsnrctl status
./bin/lsnrctl status

以及tnsping;

oracle /u01/app/oracle/product/12.1.0/dbhome_1 $ ./bin/tnsping ap-ora-records-test

然后我尝试获取一段数据 - SQL> SELECT * from MYSQL.users@mysql;，结果如下：

ERROR at line 1:
ORA-28545: error diagnosed by Net8 when connecting to an agent
Unable to retrieve text of NETWORK/NCR message 65535
ORA-02063: preceding 2 lines from MYSQL

我哪里错了？

编辑1：

这是我的创作代码;

CREATE SHARED PUBLIC DATABASE LINK mysql_remote_shared
CONNECT TO root IDENTIFIED BY password
AUTHENTICATED BY root IDENTIFIED BY password
USING 'mysql';
