Buy Valium Cheap Online Uk O objetivo deste artigo é explicar como criar o ASM pelo rawdevices com partições de um único disco.
Podemos criar várias partições com vários discos, porém estarei utilizando apenas um disco.
OBS: O recomendado é que se tenha vários discos para o uso do ASM para a alta disponibilidade dos dados.

source link Vamos criar no linux as partições para definirmos os rawdevices para o uso do Oracle ASM.
OBS: No fdisk do linux para criar uma partição entre com a letra “n” e após criar as mesmas digite “w” para atualizar a tabela das partições.
Para ver a lista completa dos comandos do fdisk digite a letra “m” para ajuda.

There is nothing wrong with that, but this is larger than 1024, and could in certain setups cause problems with: 1) software that runs at boot time (e.g., old versions of LILO) 2) booting and partitioning software from other OSs (e.g., DOS FDISK, OS/2 FDISK) Command (m for help): p Disk /dev/sda: 42.9 GB, 42949672960 bytes 255 heads, 63 sectors/track, 5221 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 * 1 16 128488+ 83 Linux /dev/sda2 17 1321 10482412+ 83 Linux /dev/sda3 1322 2365 8385930 83 Linux /dev/sda4 2366 5221 22940820 5 Extended /dev/sda5 2366 2757 3148708+ 82 Linux swap / Solaris Command (m for help): n First cylinder (2758-5221, default 2758): Using default value 2758 Last cylinder or +size or +sizeM or +sizeK (2758-5221, default 5221): 3408 Command (m for help): n First cylinder (3409-5221, default 3409): Using default value 3409 Last cylinder or +size or +sizeM or +sizeK (3409-5221, default 5221): 4059 Command (m for help): n First cylinder (4060-5221, default 4060): Using default value 4060 Last cylinder or +size or +sizeM or +sizeK (4060-5221, default 5221): 4710 Command (m for help): n First cylinder (4711-5221, default 4711): Using default value 4711 Last cylinder or +size or +sizeM or +sizeK (4711-5221, default 5221): Using default value 5221 Command (m for help): p Disk /dev/sda: 42.9 GB, 42949672960 bytes 255 heads, 63 sectors/track, 5221 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 * 1 16 128488+ 83 Linux /dev/sda2 17 1321 10482412+ 83 Linux /dev/sda3 1322 2365 8385930 83 Linux /dev/sda4 2366 5221 22940820 5 Extended /dev/sda5 2366 2757 3148708+ 82 Linux swap / Solaris /dev/sda6 2758 3408 5229126 83 Linux /dev/sda7 3409 4059 5229126 83 Linux /dev/sda8 4060 4710 5229126 83 Linux /dev/sda9 4711 5221 4104576 83 Linux Command (m for help): w The partition table has been altered!

Buy Valium From Mexico Pronto criamos as partições no linux. Agora vamos criar os rawdevices de tais partições para implementarmos o Oracle ASM.
Vamos ver novamente as partições e vamos utilizar as partições criadas para usar nas rawdevices.
