ASMLib for RHEL6

Details

Oracle ASMLib availability and support. Kernel module kmod-oracleasm package is
now available for Red Hat Enterprise Linux 6.

Oracle ASM (Automated Storage Management) is a data volume manager for Oracle
databases. ASMLib is an optional utility that can be used on Linux systems to
manage Oracle ASM devices. ASMLib consists of the following components:

- kmod-oracleasm (open-source (GPL) kernel module package)
- oracleasm-support (open-source (GPL) utitilies package)
- oracleasmlib (proprietary library package)

ASM features and functionality are available without ASMLib. The use of ASMLib
does not affect database performance.

The ASMLib kernel module package is now available in the Red Hat Enterprise
Linux 6 Supplementary RHN channel. Red Hat Enterprise Linux 6 customers who use
ASMLib can obtain the other two components using the instructions here:

The ASMLib kernel module package is provided for the convenience of our
customers but is not supported, nor are the ABIs guaranteed per Red Hat's
Supplementary software package support terms available at
https://access.redhat.com/support/offerings/production/scope_moredetail.html.

Please note that Red Hat is continuing to develop fully open-source alternatives
to ASMLib. Red Hat has provided a reference architecture for Oracle RAC
clusters using upstream-accepted technologies such as dm-multipath and udev.
This reference architecture is available at:
