---# End Stacktrace #-----------------------------

 

  • hostname is in mixed case (in this example upper case)
$ grep RACNODE /etc/hosts
10.0.0.101 RACNODE1.US.ORACLE.COM RACNODE1
10.0.0.102 RACNODE2.US.ORACLE.COM RACNODE2

 

  

Cause

Upper or mixed case hostname being used, this is being investigated in bug 17580744

Duplicates:

BUG 17666448 - INS-06006 OCCURS IF HOSTNAME IS IN CAPITAL LETTERS FOR GI INSTALLATION

BUG 17675476 - PASSWORDLESS SSH CONNECTIVITY NOT SET UP BETWEEN THE FOLLOWING NODES


 

Solution

The bug is fixed in 12.1.0.2

The workaround is to either allow OUI or manually (note 300548.1) setup ssh user equivalence for the installing user, then in command line window, ensure ssh doesn't prompt for password for both real hostname and lower case hostname. 

For example:

$ ssh RACNODE1 date                    ====>> real hostname for node1
Fri Nov 8 10:01:03 PST 2013      
$ ssh racnode1 date                    ====>> lower case hostname for node1
Fri Nov 8 10:01:04 PST 2013
$ ssh RACNODE2 date
Fri Nov 8 10:01:05 PST 2013
$ ssh racnode2 date
Fri Nov 8 10:01:06 PST 2013

 

In the case of upgrade, the alternate workaround is to update inventory to set to lower case nodename instead of real hostname:

$ /oui/bin/runInstaller -updateNodelist ORACLE_HOME= "CLUSTER_NODES={racnode1,racnode2}" CRS=true

Note in above command it's racnode1,racnode2 in lower case despite the hostname is upper case.
