配置静态监听解决ORA-12514错误的案例
配置静态监听解决ORA-12514错误的案例
今天做Linux下DG配置的时候，遇到一个现象，tnsname.ora文件配置都正常，tnsping也正常，监听也正常，但是仍然报ORA-12514错误： SQL> set lin 130 pages 130 SQL> select dest_id,error from v$archive_dest; DEST_ID ERROR ---------- ----------------------------------------------------------------- 1 2 ORA-12514: TNS:listener does not currently know of service requested in connect descriptor 3 4 5 6 7 8 9 10 --查看主库监听 SQL> !lsnrctl status LSNRCTL for Linux: Version 10.2.0.5.0 - Production on 08-OCT-2014 12:31:46 Copyright (c) 1991, 2010, Oracle.
