Oracle11g RAC + DG 搭建过程中,在备库进行 duplicate时报错如下:
[oracle@xxxx-dg:/u01/app/oracle/11.2/db_1/dbs]$rman target sys/password@racdb auxiliary sys/password@racdg nocatalog Recovery Manager: Release 11.2.0.4.0 - Production on Fri Abc 21 17:33:01 xxxx Copyright (c) 1982, 2011, Oracle and/or its affiliates.

通过
RMAN-04006: error from auxiliary database: ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist Linux-x86_64 Error: 2: No such file or directory
可看到,由于连接数据库失败导致的,回头发现,之前通过Rman连接数据库时,备库已经是启动到nomount状态了,但是当进行
RMAN> duplicate target database for standby from active database nofilenamecheck;
时,备库不知由于什么原因down掉了,查看alert日志,发现确实在RMAN连接上之后,备库nomount启动之后,数据库进行过shutdown immediate操作,重新将数据库启动至nomount状态,startup nomount。再次进行
duplicate
未报同样错误
