在介绍ORA-20079前我们先简单介绍一下resync catalog:通常,如果我们一直使用catalog来做backup or restore的话就不需要手工的做

在介绍ORA-20079前我们先简单介绍一下resync catalog:

Using the RESYNC CATALOG Command
Any structural changes to the database cause the control file and recovery catalog to become “out of synch.” The catalog will be synchronized automatically when a BACKUP or COPY command is issued with a connection to the catalog. However, this synchronization can cause a [B]delay[/B] in the backup operation.

在RMAN中使用catalog时,会使用同步命令来保证catalog与目标数据库的controlfile的內容一致。

通常,如果我们一直使用catalog来做backup or restore的话就不需要手工的做同步,,因为我们发出的backup or restore命令完成后会自动同步catalog和controlfile中的內容,只有我们有时候用catalog,而有某些时候又不用catalog来做backup or restore的时候才需要发出 resync catalog的命令来手工做同步。Oracle同步catalog时,会先建立个snapshot controlfile并且比较这个文件和catalog,完成比较后,oracle根据这个snapshot controlfile来同步catalog,并使它们保持一致。

公司的某套生产环境库为11.2.0.3RAC+DG(AIX),在备库上作备份。一次发现备份失败,报错如下:

在mos上找到了几个处理方案,可供参考
