Oracle 10G RAC Cross-Instance Archivelog delete steps

当RAC的归档日志是交叉归档在各个节点的本地磁盘,此时在单独一个节点上删除RAC的归档日志,另外一个节点上的日志不会被删除.

RMAN>run{

allocate channel c1 device type disk format '/u02/backup/%U' connect sys/manager@rac1;

allocate channel c2 device type disk format '/u02/backup/%U' connect sys/manager@rac2;

delete noprompt archivelog all;或者delete archivelog until time 'sysdate-5';

}

保证两个节点上的归档日志全部删除.

RMAN> connect target *
