如果你listener.ora配置文件是这样的 说明少了一些配置信息应指出监听那个数据库应加上
(SID_DESC =
(GLOBAL_DBNAME = GKBM2015) //为数据库服务名
(ORACLE_HOME = D:\oracle\product\10.1.0\Db_1)
(SID_NAME = GKBM2015) //为数据库服务名
)
(SID_DESC =
(GLOBAL_DBNAME = ZYXX2015) //为数据库服务名
(ORACLE_HOME = D:\oracle\product\10.1.0\Db_1)
(SID_NAME = ZYXX2015) //为数据库服务名
)
之后的文件是这样的
# listener.ora Network Configuration File: D:\oracle\product\10.1.0\Db_1\network\admin\listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = D:\oracle\product\10.1.0\Db_1)
(PROGRAM = extproc)
)
(SID_DESC =
(GLOBAL_DBNAME = GKBM2015)
(ORACLE_HOME = D:\oracle\product\10.1.0\Db_1)
(SID_NAME = GKBM2015)
)
(SID_DESC =
(GLOBAL_DBNAME = ZYXX2015)
(ORACLE_HOME = D:\oracle\product\10.1.0\Db_1)
(SID_NAME = ZYXX2015)
)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = cust-e44050fe71)(PORT = 1521))
)
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
)
)
)
之后重启监听程序
cmd命令中输入 lsnrctl
stop
start
Oracle ORA-12514: TNS:listener does not currently know of service requested in conn解决方案
