Oracle自动存储管理 ASMLib的支持变化

在Oracle Linux 6推出来以后,很多用户已经在跃跃欲试。在Linux 6中,ASMLib上有一个变化早已在Metalink上公布。参见Metalink Note 1089399.1。

Oracle指出:

For RHEL6 Oracle will only provide ASMLib software and updates via Unbreakable Linux Network(ULN). Oracle will no longer provide ASMLib packages for Red Hat kernels.

也就是说,在Oracle将仅通过ULN来提供ASMLib,之前通过OTN提供公众下载的ASMLib将不再可用。Oracle也将不再针对RedHat Kernels提供ASMLib包,虽然ASMLib对于Linux ASM不少必不可少,甚至有很多用户避免去使用它,但是这一变化还是会让很多熟悉ASMLib的用户感到不便。

OEL6据说针对数据库的优化会带来大幅度的性能提升,在OLTP性能测试中,同等内核比较,Oracle Linux Kernel会带来75%的性能提升:

Fast: More than 75 percent performance gain demonstrated in OLTP performance tests over a Red Hat Compatible Kernel; 200 percent speedup of Infiniband messaging; 137 percent faster solid state disk access.
Modern: Pro vides optimizations for large NUMA servers; improved power management and energy efficiency; fine grained CPU and memory resource control.
Reliable: Supports the Data Integrity Extensions and T10 Protection Information Model, to stop corrupt data from being written to storage; hardware fault management enables improved application uptime; low overhead performance counters for tracing.
Optimized for Oracle: Built and tested to run Oracle hardware, databases, and middleware with the best Linux performance and reliability available.
看来Oracle将不遗余力的将Linux用户吸引到Oracle Linux上来。

不厚道. 强行拉客.

Oracle Linux Kernel会带来75%的性能提升,此数据值得怀疑哦

拭目以待,看其实际应用中的表现

oracle的这个策略会让很多人不舒服甚至反感的
