[root@bip java]# alternatives –config java

There are 3 programs which provide ‘java’.

Selection Command
———————————————–
* 1 /usr/lib/jvm/jre-1.4.2-gcj/bin/java
2 /usr/java/jdk1.7.0_15/bin/java
+ 3 /usr/java/jdk1.6.0_41/bin/java

Java HotSpot(TM) 64-Bit Server VM (build 23.7-b01, mixed mode)

Step 6 :

If you want set the java home path in oracle

[root@bip ~]# su – oracle
[oracle@bip ~]$ vi .bash_profile

#Java Settings
JAVA_HOME=/usr/java/jdk1.7.0_15; export JAVA_HOME
PATH=/usr/sbin:$PATH; export PATH
PATH=$JAVA_HOME/bin:$PATH; export PATH

save it

Step 7:

[oracle@bip ~]$ which java
/usr/java/jdk1.7.0_15/bin/java

Step 8:

Symbolic creation

[root@bip jvm]# ln -s /usr/java/jdk1.7.0_15 /usr/lib/jvm/jdk1.7.0_15

[root@bip jvm]# ls -l jdk1.7.0_15
lrwxrwxrwx 1 root root 21 Feb 23 22:50 jdk1.7.0_15 -> /usr/java/jdk1.7.0_15

vncserver configuration

Step 1:  Login as root user

Install vncserver rpm package, check whether its already installed or not

vnc-server-4.1.2-14.el5_5.4.x86_64.rpm

[root@ebsdev ~]# rpm -q vnc-server-4.1.2-14.el5_5.4.x86_64
vnc-server-4.1.2-14.el5_5.4
[root@ebsdev ~]#

Step 2: password for vncserver

[root@ebsdev ~]# vncpasswd
Password:
Verify:
[root@ebsdev ~]#

Step 3:

[root@ebsdev ~]# vncserver
xauth: creating new authority file /root/.Xauthority

New ‘ebsdev.ace-ins.com:1 (root)’ desktop is ebsdev.ace-ins.com:1

Creating default startup script /root/.vnc/xstartup
Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/ebsdev.ace-ins.com:1.log

Step 4:

[root@ebsdev ~]# vi .vnc/xstartup
#!/bin/sh

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

[ –x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ –r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
xterm -geometry 80×24+10+10 -ls -title “$VNCDESKTOP Desktop” &
twm &

remove the command from unset and exec

[root@ebsdev ~]# vi .vnc/xstartup
#!/bin/sh

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

[ –x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ –r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
xterm -geometry 80×24+10+10 -ls -title “$VNCDESKTOP Desktop” &
twm &

Step 5:

[root@ebsdev ~]# vncserver -kill :1
Killing Xvnc process ID 20106
[root@ebsdev ~]#

Step 6:

[root@ebsdev ~]# vncserver

New ‘ebsdev.ace-ins.com:1 (root)’ desktop is ebsdev.ace-ins.com:1

Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/ebsdev.ace-ins.com:1.log

[root@ebsdev ~]#

Step 7: Download vncviewer

http://www.realvnc.com/download/viewer/

Step 8:  connect the host with vncviewer

Note : Some times you cann’t able connect your host, in this case check your firewall of linux and If already vncserver process aviable, kill the session using by vncserver -kill :1
