Oracle11g RAC + DG 搭建過程中,在備庫進(jìn)行 duplicate時(shí)報(bào)錯(cuò)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.

通過
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,由于連接數(shù)據(jù)庫失敗導(dǎo)致的,回頭發(fā)現(xiàn),之前通過Rman連接數(shù)據(jù)庫時(shí),備庫已經(jīng)是啟動(dòng)到nomount狀態(tài)了,但是當(dāng)進(jìn)行
RMAN> duplicate target database for standby from active database nofilenamecheck;
時(shí),備庫不知由于什么原因down掉了,查看alert日志,發(fā)現(xiàn)確實(shí)在RMAN連接上之后,備庫nomount啟動(dòng)之后,數(shù)據(jù)庫進(jìn)行過shutdown immediate操作,重新將數(shù)據(jù)庫啟動(dòng)至nomount狀態(tài),startup nomount。再次進(jìn)行
duplicate
