    R12 Multi node installations issue.

    Manish_Chaudhari

      Hi Team,

       

      I have installed oracle applications R12.1 on RHEL 6.5

       

       

      NODE_NAME    Conc_Node  Form_Node  Web_Node   Admin_Node DB_Node    Status

      ------------            ----------             ----------          ----------           ----------       ----------      -----------

      Node 1               Yes                  Yes             Yes               Yes             No         Enabled

      Node 2              Yes                   Yes             Yes               Yes             Yes        Enabled

       

      There are 2 nodes ... node 1 ( web node , concurrent node , form node , admin node )

                                     node 2 ( Database node , web node , concurrent node , form node , admin node )

       

      Installations completed successfully..

      But the issue is ... when i tried to hit the URL https://node2:domainname.com:8003    it is pointing to node 1 only (http://node1.domainname.com:8003).

      all the connections are happening through node 1 only ..

      I have clean up FND_nodes and run autoconfig on database,app-node1 and app-node2 , still the same issue persists.

       

      Could you please someone explain if I missed any post step. it would be good if we have any docs for multinode installtions.

       

      Also from database level, it is showing only one node entry.

       

      SQL> select home_url from icx_parameters;

      HOME_URL

      ------------------------------------------------------------------------------------

      http://node1.domainname.com:8003/OA_HTML/AppsLogin

       

      Am I missing to add entries in in any environment file.

       

      Thanks in advance.

       

      Regards,

      Manish

          If you want to keep run your env on two node, The database on first node, no need to enable other services and Second node (Application + web) should have all services enabled.

            Hi ,

             

            I have enabled all services (Root Services ,Web Entry Point Services ,Web Application Services ,Batch Processing Services ,Other Service Group) on node 1 and node 2 .

            then database should display both node URL entries in ICX_parameters. am I right?

             

            Do you think I should enable batch processing services on node1 only. for node 2 it should be disable. Is that cause a issue.?

             

            please let me know .

                Hi Azhar,

                 

                I referred your docs.  as per your doc. you have one web node , one CM node and one database node.

                 

                as per my architecture.... I have 2 physical servers . one server having database and applications (CM,web,apache) and another server having only applications (CM, web , Apache)

                My question is :

                1. Can I configure CM on both applications server by enabling batch processing.

                2. there are 2 different web applications services , then it should show url entries of both applications services in ICX_Parameters

                           like      http://node1.abc.com

                                      http://node2.abc.com

                 

                if yes, when i click on any URL it is pointing to node1 URL .

                 

                My intention is i need to configure load balancer for both the applications web server.

                and I need to configure PCP on both applications services.

                 

                Could you please correct on this.!!

                    Manish. Its very simple and I will help you through.

                     

                    1. In Multi-Node always remember that the URL will point to only 1 Node. Starting from R12, the last node where you run autoconfig, will be the node. So its absolutely fine.Even if you type, node.domainname.com:port it will go to node 1 only. So usually, DBAs run autoconfig in the order 1-2-1 so that it will point to Node 1.
                    2. Secondly, if you are configuring Load Balancing, it depends on how you are configuring. If its DNS for e.g. Change the following 4 parameters in both the context files and update in DNS server. Lets say you the want the URL to be erp.domainname.com:port then set s_external_url - erp.domainname.com:port ....., s_login_page: erp.domainname.com:port.... ,s_webentryhost - erp, s_webenrtydomain - domainname.com
                    3. Batch processing can be enabled in any number of nodes. Simply enable primary and secondary nodes in Concurrent--> Manager--> Define for PCP
