仔细研究一下！

在11gR2, CRS分为两个stack, lower stack和upper stack, 前者由OHASD启动. 英文释义为:
Oracle Clusterware consists of two separate stacks. The upper stack anchored by the Cluster
Ready Services daemon (crsd) and a lower stack anchored by the Oracle High Availability
Services daemon (ohasd). These two stacks have several processes that facilitate cluster
operations. The following chapters will describe them in detail.

The OHASD is the daemon which starts every other daemon that is part of the Oracle
Clusterware stack on a node. OHASD will replace all the pre-11.2 existing init scripts.
