HOW TO ACCESS MY VISION INSTANCE GLOBALLY?

Dear legends,

Since i have installed a VISION INSTANCE 12.1.1 and i have a domain name, and my entries as follows OS : ORACLE LINUX 5.7 x86_64

OUR ORGANISATION'S IP EXAMPLE
IP FOR THE MACHINE USING : 192.168.1.1
SUBNET MASK : 255.255.255.0
DEFAULT GATEWAY : 192.168.1.10

PRIMARY DNS : 50.51.52.53
SECONDARY DNS : 300.200.100.1

vi /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0
BOOTPROTO=static
BROADCAST=192.168.1.xxx
HWADDR=xx:xx:xx:xx:xx:xx
ONBOOT=yes
TYPE=Ethernet
USERCTL=no
IPV6INIT=no
PEERDNS=yes
IPADDR=192.168.1.1
NETMASK=255.255.255.0
NETWORK=192.168.1.0
#GATEWAY=192.168.1.10

vi /etc/sysconfig/network

NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=devl.rel.net -- example hostname
GATEWAY=192.168.1.10

cat resolv.conf
# Generated by NetworkManager
search rel.net
nameserver 50.51.52.53 -- example DNS 1 or primary DNS

EITHER i give or edit all the above mentioned files to access my EBS home page using the url http://devl.rel.net:8000/ i cant able to access the page but other sites can be browsed, since at the time of installation of oracle linux i have given the hostname as devl.rel.net and our domain name is rel.net.

Please can anyone help how to access my EBS globally. I have accessed the EBS login page for the first time at the time of installation only after that i cant able to access. Instance is working fine, everything has been started. I have pinged the same url ping devl.rel.net it says 0% packet loss from a terminal.

Lots of thanks and Great help would be appreciated more.

With Regards,
Karthik Singh

    You said Globally?
    Can you access it locally using e.g : http://devl.rel.net:8000/OA_HTML/AppsLocalLogin.jsp?

    Source your environment and do:

    $ grep login $CONTEXT_FILE


    What do you get?

    Does autoconfig run successfully?

    You have two options here.

    - Option 1 (Non-secure): Give a real IP Address (keep the same domain name and host name if you want or change it).

    How to change the IP Address on a R12 EBusiness Suite Installation [ID 554843.1]
    How to Clean Nonexistent Nodes or IP Addresses From FND_NODES [ID 260887.1]

    If you want to change the hostname/domainname, refer to these docs (applicable to 11i and R12):

    How to change the hostname and/or port of the Database Tier using AutoConfig [ID 338003.1]
    How to change the hostname of an Applications Tier using AutoConfig [ID 341322.1]

    - Option 2 (Secure): Implement DMZ

    Hi,

    I am able to access http://devl.rel.net:8000/OA_HTML/AppsLocalLogin.jsp? locally in the same machine.

    autoconfig ran successfully nothing problem, db, apps everything works fine.

    The only problem if i edit the IP address from STATIC to DHCP i cant able to access it in the same machine itself.

    Please I have installed VISION INSTANCE on my own by learning oracle bible's.

    This is an expected behavior.

    I have already provided the solutions you can follow in my previous reply.

    Hi Hussein,

    Thanks a lot for your suggestion, but i dont want to change my IPADDRESS or HOSTNAME or DOMAINNAME. just i need the same IP, HOST, DOMAIN but it should be accessible for others via internet, that is my scope. Why bcoz we have paid for the DOMAINNAME and I have set the machine's IP in our ROUTER.

    So without changing these strategies is there a way to do it.

    Can you ping your server IP Address and hostname.domainname from any external network? If yes, then you should be able to access the application globally. If the ping does not work, then this needs to be fixed first before trying to access the application.

    Is your machine within the same network or it is in the external network?

    Is the firewall enabled on the application server?

    Hi Hussein,

    Is your machine within the same network or it is in the external network? no my windows machine is from a external n/w which am trying from home.

    Is the firewall enabled on the application server? am not much aware of the APPLICATION SERVER FIREWALL, but am sure that i did not enabled any kind of FIREWALL during the process of installating R12 and also OEL, even i have disabled SELINUX.

    Thanks & Regards,

    By default, Firewall is enabled when you install OEL/RHEL unless you select to disable it. To disable it, please see these links.

    Hi Hussein,

    Am aware of OS firewall since it is being diabled only during the installation and also i have checked now.

    Addresses beginning with 192.168.x.x are private addresses that are not available on the internet. You will need to get a real IP address.

    Hi Srini,

    Thanks for your reply, so i need to give the IP address instead of 192.168.1.1 as [6x.7x.1xx.1xx] this is the DNS given since i get an IP while pinging

    ping devl.rel.net

    Pinging devl.rel.net [6x.7x.1xx.1xx] with 32 bytes of data:

    So whether i have to give the IP in the /etc/hosts file as DNS IP and then what will be the machine's IP should i have to give? is it right or wrong?

    If wrong what to be given?

    You have to change your IP Address in the /etc/hosts file of the application server and at the OS level to a real one as mentioned in my first reply above.

    Thanks,
    Hussein
