Don't forget to run the adrelink after each clone !!


roubleshooting Issues with Report Review Agent (FNDFS) in APPS 10SC [ID 98093.1]

Mailer Fails to Send Email Notifications after cloning

.
After cloning, mails were not floating through workflow mailer although all agent listener and notification mailer was up and running.

Issue:-
After some time we checked latest mailer log FNDCPGSCXXXXX.txt at $APPLCSF/$APPLLOG.
Below error was their in logs:-
'Problem obtaining the HTML content oracle.apps.fnd.wf.common.HTTPClientException: Unable to invoke method HTTPClient.HTTPConnection.Get caused by: java.net.ConnectException: Connection refused'

Investigation:-
what i got to know after bit of investigation is at the time we brought down source instance for cold back up, some of the workflows were in queue and they might be using source instance webserver address. After clone Since the mailer still had some events with the old url in the queue, the mailer fails with connection refused error and goes down after 10 attempts.

Solution:-
Solution is to purge the wf_notification_out outbound message queue and repopulates from the WF_NOTIFICATION table.

PFB complete solution:-

1. Stop the Workflow mailer.

2. Purge the wf_notification_out queue and recreate it out of the wf_notifications table by executing:
cd $FND_TOP/patch/115/sql
sqlplus APPS/ @wfntfqup.sql APPS APPLSYS

3. Start the mailer

4. Retest the issue by submitting the same workflow again.

Request URI:/OA_HTML/AppsLocalLogin.jsp java.lang.NoClassDefFoundError

Oracle Applications login page sometimes will have the Exception: java.lang.NoClassDefFoundError.
Request URI:/OA_HTML/AppsLocalLogin.jsp
Exception:
java.lang.NoClassDefFoundError
The workaround used to solve this Exception: java.lang.NoClassDefFoundError was to rebounce the Apache server in Oracle Applications. Aside from rebounce the Apache server in Oracle Applications, you have to remove the server side cache as well.
Stop the Apache Web Listener
$ cd $COMMON_TOP/admin/scripts/$CONTEXT_NAME
$ ./adapcctl.sh stop
Rename the Apache server side cache _pages folder to another name
$ mv $COMMON_TOP/_pages $COMMON_TOP/_pages_backup
Start the Apache Web Listener
$ cd $COMMON_TOP/admin/scripts/$CONTEXT_NAME
$ ./adapcctl.sh stop
For a permanent solution to solve java.lang.NoClassDefFoundError:
This error was caused by the Distributed JVM Cache was enabled and it can be solve by disabling Distributed JVM Cache is achieved by changing “LONG_RUNNING_JVM=” from “true” to “false” in the jserv.properties.
This is controlled by AutoConfig parameter “s_long_running_jvm”. You can change the setting “s_long_running_jvm” in $CONTEXT_FILE and run the Autoconfig to reflect the setting. Please do refer Metalink for the changes you going to make and please test it before apply it to any Production server. Monitor the frequency of java.lang.NoClassDefFoundError after deploying the solutio

How to find ICM log on Oracle Apps 11i and R12

All Concurrent Mangers log files are located in the $APPLCSF/$APPLLOG location.The following bellow options are available to get the latest log files.

Option1:
Login to Apps User and source environment file

cd $APPLCSF/$APPLLOG
ls -lrt *$TWO_TASK*

• Internal Concurrent Manager Log:_MMDD.mgr

Here you can see other list of log files which are related to concurrent mangers.The name conversation for the concurrent manger log files are

• Standard manager log: w.mgr
• Transaction manager log: t.mgr 
• Conflict Resolution manager log: c.mgr

Where: is the concurrent process id of the manager
Option2:
Log-in to the Apps User
Run Source environment file
Connect to sqlplus and run this query

SELECT 'ICM_LOG_NAME=' || fcp.logfile_name
FROM fnd_concurrent_processes fcp, fnd_concurrent_queues fcq
WHERE fcp.concurrent_queue_id = fcq.concurrent_queue_id
AND fcp.queue_application_id = fcq.application_id
AND fcq.manager_type = '0'
AND fcp.process_status_code = 'A';

Sample Output:

'ICM_LOG_NAME='||FCP.LOGFILE_NAME
-------------------------------------------------------------
ICM_LOG_NAME=/applprod/comndev/admin/log/DEV_moon1/DEV_0426.mgr

Option3:
Log in to Sysadmin Responsibility
Go to ->Concurrent -> Manager -> Administer -Processes -> Click button Internal Manager Log.
