关于IBM PowerSC 软件与Oracle RAC的恩怨
背景介绍:
IBM PowerSC 是一款安全方面的软件产品,其详细介绍可以见:http://www-03.ibm.com/systems/power/software/security/

恩怨的原文请见:
AIX: After Installing PowewSC: CRSD on the 2nd node is not able to Start with "proath_master:100b: Polling,connect to master not complete" (Doc ID 2056429.1)

在上面的MOS文章中,说的是在RAC的node1上安装并启用了IBM PowerSC 软件,

然后 CRSD is not able to start successfully on the 2nd node,it ends in INTERMEDIATE status

原因是:
CAUSE

IBM PowewSC disables some UDP/TCP related features and has network packet filtering feature,it blocks the private network layer communication,causing CRSD can not communicate with each other and the 2nd node CRSD can not join the cluster.

SOLUTION

Shutdown CRS on both nodes
Remove the IBM PowerSC software from node 1
Restart CRS on both nodes,after that CRSD are ONLINE on both nodes.
