imp orcale导入数据库命令急啊
安装oracle时我把标识和数据库名不一致请看我在select * from v$instance;查询到的
INSTANCE_NUMBER INSTANCE_NAME HOST_NAME
1 yan0526 YAN
再把情况说下我用以下命令:
imp system/sys@yan0526 FILE=E:\yan68.dmp FROMUSER=(Sb_Js,) TOUSER=(Sb_Js) log=imp_log.txt
跟踪的提示:
IMP-00058: 遇到 ORACLE 错误 12154
ORA-12154: TNS: 无法解析指定的连接标识符
IMP-00000: 未成功终止导入
我贴下 LISTENER.ora
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = F:\oracle\product\10.2.0\db_2)
(PROGRAM = extproc)
)
(SID_DESC =
(GLOBAL_DBNAME = yan)
(SID_NAME = yan0526)
)
)
LISTENER =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = yaN)(PORT = 1521))
)
我贴下 LISTENER.ora
YAN =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = yaN)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = yan)
)
)
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(Key = EXTPROC0))
)
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
)
)
我贴下sqlnet.ora
SQLNET.AUTHENTICATION_SERVICES= (NTS)
NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)
现在本人真是不知道咋办了唉,跪求答案哇。谢谢尼
------解决方案--------------------
你是在本机执行的imp指令吗?
tnsping yan0526 能否响应?
一般这种情况下,我的做法是, 借助oracle的net config assistant 把监听和 tns连接重新配置一遍再试试。
检查一下 你的tnsname.ora的yan0526 说明前面是否有空格。
