[Error Situation]
When Encrypted Control Communication (ECC) is enabled at Cluster Environment,
if DP services are restarted , CRS doesn't start up correctly although "omnisv -status" command shows CRS is "Active" .
Even if omnicc command is executed or DP GUI is started , CRS never responds .
If ECC is disabled , the issue doesn't occur even if DP services are restarted .
[Cause]
It is caused by a connection verification that was introduced as an extra security measure in 9.07 .
The issue will occur at Cluster environment because certificate Common Name(CN) doesn't match .
( CN is physical node name , but virtual name is used to communicate internally )
[Fix]
The issue will be resolved at DP9.09 .
[Workaround]
Set omnirc variable OB2_CONNECTION_CN_CHECK=0 on physical nodes of cell server cluster.
It will disable the additional connection verification as the same as 9.06 .
By disabling it , there is not any security risk .
