Oracle 外网访问

环境：centos7+oracle 11gr2

公网：固定IP

症状：1521端口正常，netmanager配置测试正常,plsql链接提示ORA-12514: TNS:listener does not currently know of service requested in connect descriptor

解决办法：

增长SID_LIST_LISTENER=

 

LISTENER=

(DESCRIPTION=

(ADDRESS_LIST=

(ADDRESS=(PROTOCOL=tcp)(HOST=sales-server)(PORT=1521))

(ADDRESS=(PROTOCOL=ipc)(KEY=extproc))))

SID_LIST_LISTENER=

(SID_LIST=

(SID_DESC=

(SID_NAME=plsextproc)

(ORACLE_HOME=/oracle10g)

(PROGRAM=extproc)))

 

参考：https://docs.oracle.com/cd/B28359_01/network.111/b28316/listenercfg.htm

 

 

须要密切注意TNSNAMES中的服务名称是否能所有显示，有时加载一部分就是解析没有经过，在配置信息没问题的状况下，PLSQL没法解析，报 could not resolve the connect identifier specified

 

附WINDOWS下的配置
