Issue:
Recently we performed clone of EBS 12.2 and post clone when we tried to launch our DMZ application we started seeing below error.
Not Found
The requested URL /OA_HTML/AppsLocalLogin.jsp was not found.
The primary node works without error. The issue is only with DMZ/Secondary node which has been added as part of the clone.
Fixes tried:
Tried to run "Generate Producte JAR Files" with force options.
Ran oJsp compilation as below
$ perl ojspCompile.pl --compile --flush -p 10 -log /tmp/ojspc_error.log
None of these helped.
Fix
Then later I realized that OA_HTML in EBS 12.2 is linked to oacore_server managed server via interface file mod_wl_ohs.conf. Apache uses this file to identify where the application is residing at then get the information.
With this information, I verified the file mod_wl_ohs.conf in /config/OHS/ and noticed that it has entries as below
$ cat /u01/EBSDB/fs1/FMW_Home/webtier/instances/EBS_web_EBSDB_OHS2/config/OHS/EBS_web_EBSD/mod_wl_ohs.conf
LoadModule weblogic_module "${ORACLE_HOME}/ohs/modules/mod_wl_ohs.so"
DynamicServerList OFF
SetHandler weblogic-handler
WLCookieName JsessionIDEkanban
WebLogicCluster ebsapp.local:6847
WLTempDir ${ORACLE_INSTANCE}/tmp
SetHandler weblogic-handler
WebLogicCluster ebsapp.local:6847
WLTempDir ${ORACLE_INSTANCE}/tmp
SetHandler weblogic-handler
WLCookieName JsessionIDYMS
WebLogicCluster ebsapp.local:6847
WLTempDir ${ORACLE_INSTANCE}/tmp
This file is missing key entries for OA_HTML. forms, etc., and thus apache is unable to redirect to actual EBS Login page.
With this details, I added the information that is missing as below and then bounced apache services.
LoadModule weblogic_module "${ORACLE_HOME}/ohs/modules/mod_wl_ohs.so"
DynamicServerList OFF
