    Issue with Load balancing for 2 Apps Node for EBS 12.1

    Hungry DBA

      Hi Guys,

       

      I had been following section 2.4 of Using Load-Balancers with Oracle E-Business Suite Release 12 (Doc ID 380489.1).

       

      As per doc, I should be able to (but which is not happening in my case)

       

      [root@ebs1 etc]# nslookup ebslbr.oracle.com

      Server:         172.18.0.99

      Address:        172.18.0.99#53

       

      Name:   ebslbr.oracle.com

      Address: 172.18.0.102

      Name:   ebslbr.oracle.com

      Address: 172.18.0.101

       

      [root@ebs1 etc]# telnet ebslbr.oracle.com

      Trying 172.18.0.101...

      telnet: connect to address 172.18.0.101: Connection refused

      Trying 172.18.0.102...

      telnet: connect to address 172.18.0.102: Connection refused

      telnet: Unable to connect to remote host: Connection refused

      [root@ebs1 etc]#

       

       

      I could able to lookup individual servers as well.

       

      [root@ebs1 etc]# nslookup ebs1

      Server:         172.18.0.99

      Address:        172.18.0.99#53

       

      Name:   ebs1.oracle.com

      Address: 172.18.0.101

       

      [root@ebs1 etc]# nslookup ebs2

      Server:         172.18.0.99

      Address:        172.18.0.99#53

       

       

      Name:   ebs2.oracle.com

      Address: 172.18.0.102

       

      [root@ebs1 etc]# cat /etc/hosts

      # Do not remove the following line, or various programs

      # that require network functionality will fail.

      [root@ebs1 etc]# telnet 127.0.0.1

      Trying 127.0.0.1...

      [root@ebs1 etc]# service iptables status

      Firewall is stopped.

      [root@ebs1 etc]#

       

      I've further went, made changes in context file...ran autoconfig...but not getting frontend with 'ebslbr' hostname.

       

      Can you please assist what could be the issue ?

       

       

      Thanks,
