Oracle ASMLib

ASMLib is an optional support library for the Automatic Storage Management feature of the Oracle Database. Automatic Storage Management (ASM) simplifies database administration and greatly reduces kernel resource usage (e.g. the number of open file descriptors). It eliminates the need for the DBA to directly manage potentially thousands of Oracle database files, requiring only the management of groups of disks allocated to the Oracle Database. ASMLib allows an Oracle Database using ASM more efficient and capable access to the disk groups it is using.

ASMLib in the Unbreakable Enterprise Kernel
  The Oracle ASMLib kernel driver is now included in the Unbreakable Enterprise Kernel.  No driver package needs to be installed when using this kernel.  The oracleasm-support and oracleasmlib packages still need to be installed from ULN.
