Oracle TNS-12514错误的解决步骤

远程客户端操作数据，发现无法连接到oracle，查看listener.log有

 19-JAN-2017 14:44:37 * (CONNECT_DATA=(SERVICE_NAME=orcl)(CID=(PROGRAM=)(HOST=jdbc)(USER=testd))) * (ADDRESS=(PROTOCOL=tcp)(HOST=11.0.0.155)(PORT=51821)) * establish * orcl * 12514
 TNS-12514: TNS:listener does not currently know of service requested in connect descriptor

查看listener.ora发现设置的有一点问题,修改为:

 SID_LIST_LISTENER =
 (SID_LIST =
 (SID_DESC =
 (SDU = 32768)
 (TDU = 32768)
 (GLOBAL_DBNAME = orcl)
 (ORACLE_HOME = /opt/oracle/11.2.0)
 (SID_NAME = orcl)
 )
 )
 

然后重启listener

 [oracle@db42 ~]$ lsnrctl stop
