5 1.2 Configurer ASMlib Configurer le driver ASMLib: ~]# oracleasm configure -i Configuring the Oracle ASM library driver. This will configure the on-boot properties of the Oracle ASM library driver. The following questions will determine whether the driver is loaded on boot and what permissions it will have. The current values will be shown in brackets ('[]'). Hitting <ENTER> without typing an answer will keep that current value. Ctrl-C will abort. Default user to own the driver interface []: grid Default group to own the driver interface []: asmadmin Start Oracle ASM library driver on boot (y/n) [n]: y Scan for Oracle ASM disks on boot (y/n) [y]: Writing Oracle ASM library driver configuration: done 2014 Hakim Benameurlaine 5
