Oracle dblink监听问题

来源：这里教程网时间：2026-03-03 14:17:58 作者：

Oracle dblink监听不能简单重启监听。（MySQL的dblink）通过lsnrctl stop、lsnrctl start无法启动Oracle dblink的监听。dblink查询报错：

SQL> select count(*) from CUX_IMP_INTERFACE_HEADERS@MYODBC.BENLAILIFE.COM;
select count(*) from CUX_IMP_INTERFACE_HEADERS@MYODBC.BENLAILIFE.COM
*
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 MYODBC


正确重启Oracle dblink监听方式：
[oraprod@erpdbp PROD_erpdbp]$ pwd
/u01/prod/db/12.1.0/appsutil/scripts/PROD_erpdbp
[oraprod@erpdbp PROD_erpdbp]$ /u01/prod/db/12.1.0/appsutil/scripts/PROD_erpdbp/addlnctl.sh stop PROD
[oraprod@erpdbp PROD_erpdbp]$ /u01/prod/db/12.1.0/appsutil/scripts/PROD_erpdbp/addlnctl.sh start PROD
[oraprod@erpdbp PROD_erpdbp]$ /u01/prod/db/12.1.0/appsutil/scripts/PROD_erpdbp/addlnctl.sh status PROD

报错：
SQL> select count(*) from CUX_IMP_INTERFACE_HEADERS@MYODBC.BENLAILIFE.COM;
select count(*) from CUX_IMP_INTERFACE_HEADERS@MYODBC.BENLAILIFE.COM

PS：
CUX_IMP_INTERFACE_HEADERS是MySQL的表。

监听正常后：
SQL> select count(*) from CUX_IMP_INTERFACE_HEADERS@MYODBC.BENLAILIFE.COM;
COUNT(*)
