Oracle 外網訪問

環境：centos7+oracle 11gr2

公網：固定IP

症狀：1521端口正常，netmanager配置測試正常,plsql鏈接提示ORA-12514: TNS:listener does not currently know of service requested in connect descriptor

解決辦法：

增長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)))

 

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

 

 

須要密切注意TNSNAMES中的服務名稱是否能所有顯示，有時加載一部分就是解析沒有經過，在配置信息沒問題的狀況下，PLSQL沒法解析，報 could not resolve the connect identifier specified

 

附WINDOWS下的配置
