aix上oracle使用rman备份到nfs

环境：aix6、oracle10G

1、配置nfs

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

nfs服务器上配置nfs yum -y install nfs-utils vim /etc/exports 增加一行 /data   *(rw,sync,no_root_squash,no_all_squash) systemctl start nfs systemctl status nfs 检查对外共享的目录。使用下列命令： showmount -e localhost   aix上挂载磁盘 在AIX系统打开NFS保留端口，命令如下： nfso -o nfs_use_reserved_ports=1 然后，将共享的/data目录挂载即可 mount 192.168.1.65:/data /data

2、rman配置备份路径（下面直接指定通道的时候就不用配置这项）

?

1 2	RMAN> configure channel 1 device type disk format '/rman/bak/%d_db_%u'; RMAN> configure channel 2 device type disk format '/rman/bak/%d_db_%u';

3、rman进行备份

?

1 2 3 4 5 6 7

RMAN> run {    allocate channel c1 device type disk format '/rman/bak/disk1/%U';    allocate channel c2 device type disk format '/rman/bak/disk2/%U';    backup database;    release channel c1;    release channel c2;    }

4、错误处理

报错

RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of backup plus archivelog command at 10/30/2020 14:02:03

Additional information: 3
在metalink上找到一个Doc,Note:424785.1。这个问题在10.2的版本中比较普遍。

直接执行

alter system set event='10298 trace name context forever,level 32'

再次备份即可
