"Why my coherence member can not join with cluster?"
This is due to the disabled ICMP OS service at Amazon virtual machine.
The member detection mechanism of Coherence is wrapped ICMP;TCMP. So, if the OS can't communicate with each other through ICMP, Coherence member join would be failed.
Follow these steps.
1. Enabling, ICMP Echo request Protocol
2. Check the iptables, open 7th port TCP/UDP inbound/outbound.
3. OS Service start
$> chconfig echo-dram on
$> chconfig echo-stream on
This solution will be heplful on other PaaS Services, which allow only UNICAST in their virtual LAN.
