ORACLE监听器 The listener supports no services 问题解决方法
安装环境：
操作系统版本：RHCLE5
ORACLE版本：11gR2
开启监听器，远程连接报错：
ORA-12514: TNS:linstener does not currently know of service requested in connect descriptor
解决问题思路：
查看监听器状态，关闭后重新启动监听器

重建监听器：
问题依旧
查看LISTENER内容：
[oracle@rhel5 admin]$ cat listener.ora
# listener.ora Network Configuration File: /u01/app/oracle/product/11.2/network/admin/listener.ora
# Generated by Oracle configuration tools.
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = rhel5.oraclelinux.com)(PORT = 1521))
)
)
ADR_BASE_LISTENER = /u01/app/oracle
在LISTENER里添加内容：
SID_LIST_LISTENER=
(SID_LIST=
(SID_DESC=
#BEQUEATH CONFIG
(GLOBAL_DBNAME=orcl)
(SID_NAME=orcl)
(ORACLE_HOME=/u01/app/oracle/product/11.2)
#PRESPAWN CONFIG
(PRESPAWN_MAX=20)
(PRESPAWN_LIST=
(PRESPAWN_DESC=(PROTOCOL=tcp)(POOL_SIZE=2)(TIMEOUT=1))
)
)
)
重启监听器，问题解决。
