On one of Oracle Applications 11i cloned instance, OAM (Oracle Application Manager) was showing  ”Application System Name” as source Instance.

like http://<url>/oa_servlets/weboam/oam/oamApps$target=source

1. My first thought was to look at FND_NODES to see if any node entry still pointing to source instance. All records in this table were pointing to target instance.

If FND_NODES contain entry to source instance, I could have cleaned it using below methods
a)Login to sqlplus as user APPS
b) EXEC FND_CONC_CLONE.SETUP_CLEAN;  (This procedure will delete all nodes from FND_NODES and related data in other tables)
c)Repopulate FND_NODES by running Autoconfig on all middle tier nodes (CM, Web Forms)

2. Next obvious thought was to look at profile option at Server, Responsibility level (During cloning only site level profile options are updated to target instance).

SQL> select PO.PROFILE_OPTION_NAME,PV.PROFILE_OPTION_VALUE, PV.LEVEL_ID
from fnd_profile_option_values pv, fnd_profile_options po
where upper(PROFILE_OPTION_VALUE) like ‘%&enter_source_in_UPPERCASE%’
and pv.PROFILE_OPTION_ID=po.PROFILE_OPTION_ID;

In above query level_id represents following level
10001 - SITE
10002 - APP
10003 - RESP
10004 - USER
10005 - SERVER
10006 - ORG
10007 - ServerResponsibility

No profile option was pointing to source instance (I already changed workflow related profile options mentioned in post clone steps)

3. Googled to check if others encountered similar issue and I got one hit here but solution was to clone again and I wasn’t convinced

4. Next Step was to identify table and column name from where OAM (Oracle Application Manager) was populating “Application System Name” in Applications Dashboard & Site Map

SELECT table_name, column_name
FROM all_tab_columns
–WHERE column_name LIKE ‘%’

After some permutations & combinations I reached to below query

SELECT table_name, column_name
FROM all_tab_columns
WHERE column_name LIKE ‘APPLICATION%SYSTEM%NAME%’;

and output was

TABLE_NAME                     COLUMN_NAME
—————————— ——————————
AD_APPL_TOPS                   APPLICATIONS_SYSTEM_NAME
FND_PRODUCT_GROUPS             APPLICATIONS_SYSTEM_NAME
BIN$TQikJhLucVHgRAADuqIcxA==%content APPLICATIONS_SYSTEM_NAME

My immediate focus was on table AD_APPL_TOPS & FND_PRODUCT_GROUPS
Checked and found that APPLICATIONS_SYSTEM_NAME in FND_PRODUCT_GROUPS was pointing to source instance where as it should be same as SID.

Fix was simply to update table FND_PRODUCT_GROUPS like

Backup existing table as
SQL>create table FND_PRODUCT_GROUPS_BAK as select * from FND_PRODUCT_GROUPS;

Update table with target name
SQL> update FND_PRODUCT_GROUPS
set APPLICATIONS_SYSTEM_NAME = ‘<NEW DATABASE NAME>’ ;
commit;
5. Final hard thing to find was which step in cloning update this table so I started digging cloning log file.

- At one step cloning runs Autoconfig on target instance which runs script

$OAD_TOP/admin/install/$CONTEXT_NAME/adadmprf.sh  (This script set profiles in database) and calls adadmprf.sql

This script does same as we did above and for some reason it failed during Autocnfig phase of Rapid Clone

REMREM Update FND_PRODUCT_GROUPS, if needed  

REM

declare  statement varchar2(200);  

  l_new_asn varchar2(30);  

begin  

  if :fpg_has_column = 'TRUE' then  

    l_new_asn := :new_apps_system_name;

    statement := 'update fnd_product_groups '||     

       'set applications_system_name = :new_asn '||  

      'where product_group_id = 1';

    execute immediate statement    using l_new_asn;  

  end if;  

-- end if applications_system_name column

exists in fnd_product_groups  

end;  

/

6. Finally to ensure that every thing is correct I executed $OAD_TOP/admin/install/$CONTEXT_NAME/adadmprf.sh again,

Bounced Apache and Application System Name pointing to target insatnce this time.
