“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)

? ? ?)

? )
