Directory: /oaph/oracle/oaphappl/fs1/FMW_Home/webtier/perl/bin/perl -I /oaph/oracle/oaphappl/fs1/FMW_Home/webtier/perl/lib/5.10.0 -I

bisdblrp.sql INSTE8_PRF 1
Solution:
Drop the duplicate DB Links and then manually run the bisdblrp.sql script and the re-run autoconfig.
drop database link APPS_TO_APPS.WORLD  (which is owned by obt_aa)
drop database link EDW_APPS_TO_WH.WORLD  (which is owned by obt_aa)
Run the failing script (bisdblrp.sql) manually:
# cd /oaph/oracle/oaphappl/fs1/inst/apps/OAPH_oacmph/admin/install/
# sqlplus apps/<passwd>
SQL>@bisdblrp.sql
when prompted define the apps username, apps password and the DBNAME for this instance
