ORA-01034 ORA-27101故障分析
客户的数据库通过监听访问报ORA-01034 ORA-27101错误无法正常使用:
SQL> conn app/xxxxx@192.168.129.145/orcl ERROR: ORA-01034: ORACLE not available ORA-27101: shared memory realm does not exist Linux-x86_64 Error: 2: No such file or directory Process ID: 0 Session ID: 0 Serial number: 0 SQL> conn app/xxxxx Connected.
检查数据库状态和tnsping都正常
SQL> select open_mode from v$database; OPEN_MODE -------------------- READ WRITE SQL> !tnsping orcl TNS Ping Utility for Linux: Version 11.2.0.4.0 - Production on 18-OCT-2020 22:11:49 Copyright (c) 1997, 2013, Oracle.

检查主机之间ping操作也正常:

检查数据库和监听配置:

这里看到数据库配置和监听配置不匹配,因此需要调整。
