run{
allocate channel c1 device type disk;
allocate channel c2 device type disk;
allocate channel c3 device type disk;
allocate channel c4 device type disk;
allocate channel c5 device type disk;
allocate channel c6 device type disk;
allocate auxiliary channel a1 device type disk;
allocate auxiliary channel a2 device type disk;
allocate auxiliary channel a3 device type disk;
allocate auxiliary channel a4 device type disk;
allocate auxiliary channel a5 device type disk;
allocate auxiliary channel a6 device type disk;
allocate channel c1 device type disk;
allocate channel c2 device type disk;
allocate channel c3 device type disk;
allocate channel c4 device type disk;
allocate channel c5 device type disk;
allocate channel c6 device type disk;
allocate auxiliary channel a1 device type disk;
allocate auxiliary channel a2 device type disk;
allocate auxiliary channel a3 device type disk;
allocate auxiliary channel a4 device type disk;
allocate auxiliary channel a5 device type disk;
allocate auxiliary channel a6 device type disk;
duplicate target database for standby nofilenamecheck from active database;
}
再次运行就没事了
