Configure Shared Appl Top in EBS R12 - Step by Step

Hi All ...

Here the step by step of configure Shared Appl Top  in EBS R12:

1.   Run adpreclone procedure in DB and APPL (on Main server):

·         On DB Tier:

        cd $ORACLE_HOME/appsutil/scripts/$CONTEXT_NAME

        perl adpreclone.pl dbTier

·         On APPL Tier:

         cd $INST_TOP/admin/scripts

         perl adpreclone.pl appsTier

2.   Stop APPL_TIER (on Main server)

3.   Add the F5 ip hosname.domain hostname to /etc/hosts on all servers.

4.   Connect the mount of the application tier to second appl server. 

5.   Add node (run the commands on second applserver ).

    cd $COMMON_TOP/clone/bin; (take a path from main appl node)

    perl adclonectx.pl addnode contextfile=<echo $CONTEXT_FILE from main node>

    *All servers need to be enabled

    perl <echo $AD_TOP/bin from main node >/adconfig.pl contextfile=<specify the path to the      new context file from previous step>

   Edit .bash_profile to point to new env files.

6.   Run AutoConfig in both nodes (main node need to be run as the last one).

7.   Edit Context file for 2 nodes

s_applcsf	Same on all nodes
s_fndreviverpiddir	Same on all nodes
APPLDCP	ON
s_appltmp	Same on all nodes
s_temp	Same on all nodes
s_custom_file	Same is in main node
s_webentryhost	F5 host
s_login_page	F5 host
s_external_url	F5 host

8.   Run AutoConfig in both nodes (main node need to be run as the last one).

9.   Start APPL tier in both nodes (main and after that secondary).

10. Enable Internal Monitor Managers for both nodes:

Go to Concurrent manager > Define > Look for Internal Monitor% > Work Shiftes

 Work Shift:Standard
  Processes: 1 > Save

 Do the same for the second one

Activate both managers.

Query which user session is on which application servers:

 select nodes.node_name,usr.user_name,usr.user_id,ses.function_type

from icx_sessions ses,

     fnd_nodes nodes,

     fnd_user usr

where ses.node_id=nodes.node_id

and ses.guest='N'

and ses.user_id=usr.user_id

order by usr.user_id,nodes.node_name

You are done.

Good luck ...
