Instalacao do ASM

Tivemos um problema recente no red hat 4 ES, mas que foi resolvido com o script

Documentacao
- Sobre o ASM - Download
http://www.oracle.com/technology/tech/linux/asmlib/index.html
- Instalacao
http://www.oracle.com/technology/tech/linux/asmlib/install.html

Com o script abaixo conseguimos prosseguir com a instalacao do ASM, lembrando que esta somente criando arquivos fisicos com o proposito de laboratorio do curso WS2.
