ASMLib Installation
ASMLib Installation
This step is only necessary if you want to use ASMLib to access the ASM disks.
Determine your kernel version using the following command as the root user.
# uname -r
2.6.18-92.el5
#
Download the ASMLib software from the OTN website, making sure you pick the version that matches your distribution, kernel and architecture. For this example I used CentOS 4.3, so the following packages were required.
Drivers for kernel 2.6.18-92.el5:
oracleasm-2.6.18-92.el5xen-2.0.5-1.el5.x86_64.rpm
oracleasm-2.6.18-92.el5debug-2.0.5-1.el5.x86_64.rpm
oracleasm-2.6.18-92.el5-debuginfo-2.0.5-1.el5.x86_64.rpm
oracleasm-support-2.1.7-1.el5.x86_64.rpm
Install the packages as the root user.
# rpm -Uvh oracleasm-2.6.18-92.el5xen-2.0.5-1.el5.x86_64.rpm
oracleasm-2.6.18-92.el5debug-2.0.5-1.el5.x86_64.rpm
oracleasm-2.6.18-92.el5-debuginfo-2.0.5-1.el5.x86_64.rpm
oracleasm-support-2.1.7-1.el5.x86_64.rpm

With the software installed, configure the ASM kernel module.

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 []: oracle
Default group to own the driver interface []: oinstall
