Solution 1581269.1 : How to Launch Web ILOM Remote Console from a VNC Session of Oracle Big Data Appliance(BDA) Node

Applies to:

Big Data Appliance X3-2 Hardware - Version All Versions and later
Big Data Appliance Hardware - Version All Versions and later
Linux x86-64

Purpose

This document provides an option on how to connect to a problematic Oracle Big Data Appliance (BDA) node(which can not be contacted via ping nor can be accessed with ssh) using Oracle Integrated Lights Out Manager (ILOM) Web interface Remote Console from one of the NON Critical BDA nodes. Since sometimes launching ILOM Remote Console for the problematic node from a Client environment is NOT feasible due to various reasons such as Firewall , Jdk version ..e

Details

Follow below steps to setup VNC on the NON Critical Node. Then from the VNC session launch ILOM Web Interface of the problematic node .

1) As root setup VNC on one of the NON Critical BDA Nodes preferably on the same Rack.
a) Edit /etc/sysconfig/vncservers

VNCSERVERS="1:root"
VNCSERVERARGS[1]="-geometry 1280x1240"

b) Create some default VNC-related files in /root/.vnc and set password for root

# vncserver :1

c) As root edit xstartup file in /root/.vnc

Uncomment the following two lines for normal desktop:
unset SESSION_MANAGER
exec /etc/X11/xinit/xinitrc

d) Restart VNC service

# service vncserver restart

2) Enable Java plugin for Firefox, which is needed to launch ILOM Remote Console.

Here scaj21bda10 is the NON Critical BDA node I have setup the VNC on.
[root@scaj21bda10 .mozilla]# pwd
/root/.mozilla
[root@scaj21bda10 .mozilla]# ls -l
total 12
drwxr-xr-x 3 root root 4096 Aug 27 13:14 extensions
drwx------ 4 root root 4096 Aug 27 13:56 firefox
[root@scaj21bda10 .mozilla]# mkdir plugins
[root@scaj21bda10 .mozilla]# ls -l
total 12
drwxr-xr-x 3 root root 4096 Aug 27 13:14 extensions
drwx------ 4 root root 4096 Aug 27 13:56 firefox
drwxr-xr-x 2 root root 4096 Aug 27 14:09 plugins
[root@scaj21bda10 .mozilla]# cd plugins
[root@scaj21bda10 plugins]# ln -s /usr/java/default/jre/lib/amd64/libnpjp2.so .
[root@scaj21bda10 plugins]# ls -l
total 0
lrwxrwxrwx 1 root root 43 Aug 27 14:10 libnpjp2.so -> /usr/java/default/jre/lib/amd64/libnpjp2.so

3) In the VNC session

a) Launch Firefox and log into problematic node ILOM Web Interface
b) Launch Remote Console

In ILOM Version 3.0.*
------------------------
Click the Remote Control tab (on the top right) ---> Click Redirection tab ---> Click on 'Launch Remote Console'

In ILOM Version 3.1.*
------------------------
Expand 'Remote Control' (in the left hand side menu) ---> Click on Redirection tab ---> Click on 'Launch Remote Console'

c) Choose to open jnlpgenerator-16 using /usr/java/default/bin/javaws

d) While launching ILOM Remote Console if a popup comes up requesting user/password then enter ILOM user/password details.

e) In the Remote Console command prompt enter the node user/password details.
