RMAN BACKUP...PLUS ARCHIVELOG命令执行步骤

BACKUP...PLUS ARCHIVELOG命令在备份过程中会依次执行下列步骤：

　　1 ）运行ALTER SYSTEM ARCHIVE LOG CURRENT语句对当前 Redolog 进行归档。

　　2 ）执行BACKUP ARCHIVELOG ALL命令备份所有已归档日志。

　　3 ）执行BACKUP命令对指定项进行备份。

　　4 ）再次运行ALTER SYSTEM ARCHIVE LOG CURRENT对当前 Redolog 归档。

　　5 ）对新生成的尚未备份的归档文件进行备份。

示例：

RMAN> backup database format '/home/oracle/full_%d_%s_%p_%T' plus archivelog delete input;
