“tnsping 监听名” 没有问题 但是连接具体某一个库却报错时
解决方法：
1. 打开<OracleHome>/network/admin/listener.ora文件，找到：
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.2.65)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = SUNRAYCHENJH)(PORT = 1521))
)
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
)
)
)
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = D:\oracle\ora92)
(PROGRAM = extproc)
)
)
)
2. 添加：
(SID_DESC =
(GLOBAL_DBNAME = orcl)
(ORACLE_HOME = D:\oracle\ora92)
(SID_NAME = ORCL)
)
3. 最后变成：
# LISTENER.ORA Network Configuration File: D:\oracle\ora92\network\admin\listener.ora
# Generated by Oracle configuration tools.
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.2.65)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = SUNRAYCHENJH)(PORT = 1521))
)
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
)
)
)
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = D:\oracle\ora92)
(PROGRAM = extproc)
)
(SID_DESC =
(GLOBAL_DBNAME = orcl)
(ORACLE_HOME = D:\oracle\ora92)
(SID_NAME = ORCL)
)
)
