Falha na instalação do Oracle-XE no Fedora Core 5

Na instalação do Oracle-xe, além da popular "libaio" sem a qual o Oracle não se instala, é preciso também garantir que o pacote "bc" também esteja instalado, do contrário podemos receber o erro abaixo no momento da instalação:

# rpm -ivh oracle-xe-10.2.0.1-1.0.i386.rpm

You must run '/etc/init.d/oracle-xe configure' as the root user to
configure the database.

Podemos notar que, apesar dos avisos de erro a instalação é concluída, pois o pacote do Oracle não valida se a "bc" está instalada. Com isso não conseguiremos de forma alguma criar a nova base por mais que rodemos o comando "/etc/init.d/oracle-xe configure".

Para resolver este problema basta que seja instalado o pacote "bc" com o yum ou através do download do rpm. No exemplo vou usar o "yum":

# yum install bc

Após a instalação do pacote "bc" é preciso remover o "Oracle-xe":
#rpm -e oracle-xe

Reinstalá-lo novamente:
# rpm -ivh oracle-xe-10.2.0.1-1.0.i386.rpm

You must run '/etc/init.d/oracle-xe configure' as the root user to
configure the database.

E seguir normalmente os procedimentos seguintes de instalação e configuração:
# /etc/init.d/oracle-xe configure

Com isso agora veremos que o comando "configure" vai criar os datafiles do Oracle-xe normalmente.
