click here O objetivo de Multiplexar os Controlfiles é totalmente importante para a segurança contra corrupção do arquivo e ou de disco.
Recomendado pela Oracle, estes devem ser multiplexados em diferentes discos e não em partições de um único disco. No ASM é sugerido que coloquemos em diferentes Grupos de Discos.
Segue abaixo o procedimento de como multiplexar o controlfile em ASM.

https://www.yolascafe.com/0ggoj5xew Vamos multiplexar os controlfiles. Neste não iremos utilizar o RMAN para fazer a cópia dos controlfiles.
Vamos utilizar o próprio ASM para a realização do mesmo.

Tramadol Online Order Cheap O que realizamos foi um procedimento de criar um backup do controlfile num outro disco de grupo e pelo ASM utilizamos o “mkalias” para linkar o arquivo criado com um outro nome de arquivo como por exemplo, control02.ctl.
OBS: Para saber mais sobre o comando “mkalias” entre em Documento Oracle ASM
