大家好：
在虚拟机中安装了redhat5+oracle10g，打开了监听，打开了em
但是为什么客户端还是访问不了？
新手，求助大家了~
本地的tsnames：
# tnsnames.ora Network Configuration File: D:\oracle\product\10.2.0\client_1\NETWORK\ADMIN\tnsnames.ora
# Generated by Oracle configuration tools.
192.168.198.131 =

(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.198.131)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = orcl)
)
)
虚拟机listener.ora：
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /oracle/app/product/10.2.0/db_1)
