Dataguard ORA-19909 ORA-01110

在创建ORACLE 10G Dataguard时，报错：

Datafile 1 (ckpscn 24967685451) is orphaned on incarnation#=6
MRP0: Background Media Recovery terminated with error 19909
Tue Jul  2 17:01:01 2013
Errors in file /app/oracle/admin/BEIACCE/bdump/beiacce1_mrp0_626.trc:
ORA-19909: datafile 1 belongs to an orphan incarnation
ORA-01110: data file 1: '+DATA_DG01/beiacce/system01.dbf'

这个报错是由incarnation引起的。

检查主备库incarnation信息

从输出信息可以看出主备库的current incarnation不一致。

 

reset备库incarnation

RMAN> reset database to incarnation 6;

database reset to incarnation 6

reset备库的incarnation后，Dataguard恢复正常。
