To Troubleshoot Workflow Notification Mailer issues, we need to understand how outbound and inbound processing works
Outbound Notification Processing –
-Creation of Workflow notification raises oracle.apps.wf.notification.send event.
-This event is deferred immediately and placed on the WF_DEFERRED agent.
-Workflow Agent Listener on WF_DEFERRED queue process the deferred subscription.
-Subscription to this event calls the Generate function (WF_XML.Generate) to generate an XML representation of the notification.
-The event is then placed on the WF_NOTIFICATION_OUT agent.
-Workflow Notification Mailer dequeues the message from WF_NOTIFICATION_OUT.
-Before the e-mail notification is sent, Workflow Notification Mailer performs the following actions:
1. Resolves the notification recipient role to a single e-mail address, which itself can be a mail list.
2. Switches its database session to the recipient role’s preferred language and territory.
3. Generates the message and any optional attachments using the appropriate message template.
4. Sends the message by SMTP protocol.
Inbound Notification Processing
-This is followed If Inbound proccessing Checkbox is enabled for it in Workflow setup
-Email received into INBOX on IMAP Server
-Inbound Workflow Notification Mailer thread queries its IMAP e-mail account for incoming message.
-Use a Java-based e-mail parser to perform high level verification checks on the message.
-If the message is a valid notification response, create an XML message and place it on WF_NOTIFICATION_IN.
-Workflow Agent Listener runs on WF_NOTIFICATION_IN dequeues the message.
Workflow executes the appropriate response function to record the response and complete the notification.
Some important point about Workflow Notification Mailer issues
For workflow mailer to work variable AF_CLASSPATH and AFJVAPRG should be set correctly in adovars.env
-Override address feature can be used to test the mailer.By providing this address,mailer sent all the mail to this address only
-$FND_TOP/sql/Wfver.sql can be used to find the version of worflow.There are some more scripts in $FND_TOP/sql which can be used to debug the workflow items
Some useful queries about Workflow Notification Mailer issues
select count(*), MSG_PRIORITY, corr_id, msg_state from applsys.aq$wf_deferred where corr_id like '%oracle.apps.wf.notification%' group by MSG_PRIORITY, corr_id, msg_state; select count(*), msg_state from applsys.aq$wf_notification_out group by msg_state select status, mail_status, count(*) from wf_notifications group by status, mail_status; select count(*), MSG_PRIORITY, corr_id, msg_state from applsys.aq$wf_error where corr_id like 'APPS:oracle.apps.wf.notification%' group by MSG_PRIORITY, corr_id, msg_state;
Log file location for Workflow Notification Mailer
Log files are located in $APPLCSF/$APPLLOG on the concurrent tier
Log file start with FNDCPGSC. There are three files,One belongs to Notification mailer while other two belongs to Workflow Agent listener
ls -ltr FNDCPGSC*.txt
Troubleshooting Workflow Notification Mailer issues
First of all here are the sanity check for Inbound and Outbound Processing
Verify Outbound Processing
1 Verify Agent Listeners are running
2 Go to the “View Details” screen for the Mailer you are configuring
3 Verify that Mailer is running
4 Click on the “Test Email” button
5 Enter a role using the LOV
6. The test address will override that role’s email address
7. Click Send, write down the Notification Id just in case
8. Verify your email account receives this email
Verify Inbound Processing
1 Send an e-mail to the Workflow Mailer reply to address
2 Subject “Hello World”
3 Body “Hello World”
4. The mailer should process this email and send back an FYI “unsolicited email” message to your email account
Now lets take some particular issues on Workflow Notification Mailer
(A) A particular user is not receiving the mail from Workflow mailer
We need to check the user preferences
recipient_role := '&username';
WF_DIRECTORY.GetRoleInfoMail(recipient_role, display_name, email,
orig_system, orig_system_id, installed);
The notification preferences determine if the notification will be emailed or not. When the notification preference is set to “Do not send me mail” then notifications are not emailed to that user.
The script in step#1 also returns the notification preference value. QUERY means “Do not send me mail”.
How to change the user’s notification preference to a value other than “Do not send me mail” ?
a. Log into the application as the user with this problem
b. Preferences (at the TOP of the main page on your right hand side).
c. Notifications Section> Email Style field
(B) Outbound Processing Not working, No mails are being send from Notification Mailer(workflow notification mailer not sending emails)
(i) Make sure Java mailer and WF Agent Listeners are up and running:
a. Workflow Administrator web Applications Responsibility
b. Workflow Manager
c. Click on the Service Components icon
The following components should be up and running:
Workflow Notification Mailer
Workflow Deferred Agent Listener
(ii) Are messages in WF_DEFERRED and WF_NOTIFICATION_OUT processed?
a. Execute the following queries:
select substr(wfd.corrid,1,40) corrid, decode(wfd.state, 0, '0 = Ready', 1, '1 = Delayed', 2, '2 = Retained', 3, '3 = Exception', to_char(substr(wfd.state,1,12))) State, count(*) COUNT from applsys.wf_deferred wfd group by wfd.corrid, wfd.state; select substr(wfd.corrid,1,40) corrid, decode(wfd.state, 0, '0 = Ready', 1, '1 = Delayed', 2, '2 = Retained', 3, '3 = Exception', to_char(substr(wfd.state,1,12))) State, count(*) COUNT from applsys.wf_notification_out wfd group by wfd.corrid, wfd.state;
b. Re-execute the same queries after 15-20 minutes of first execution and compare the number of messages in READY state/status. The number messages in READY state/status should decrease.
(iii) Check the SMTP server
Here is the check
|telnet <SMTP SERVER> 25||Enter|
|Trying 192.avc.ass…. |
Connected to <SMTP SERVER>.
Escape character is ‘^]’.
220 <SMTP SERVER> ESMTP Sendmail 8.13.8/8.13.8; Fri, 19 Mar 2016 15:4 0:07 -0400
|EHLO <SMTP SERVER>||Enter|
|250-<SMTP SERVER> Hello <SMTP SERVER> [22.214.171.124], pleased to meet you |
250-AUTH DIGEST-MD5 CRAM-MD5
|MAIL FROM:workflow-<ORACLE_SID>@<SMTP SERVER>||Enter From address|
|250 2.1.0 workflow-<ORACLE_SID>@<SMTP SERVER>… Sender ok|
|RCPT TO:[email protected]||Enter To address|
|250 2.1.5 [email protected]… Recipient ok|
|354 Enter mail, end with “.” on a line by itself|
|Test message from <SMTP server>||Enter the message|
|.||enter a . by itself on a new line|
|250 2.0.0 o2JJe7Ip016348 Message accepted for delivery|
|221 2.0.0 <SMTP SERVER> closing connection |
Connection closed by foreign host.
Run $FND_TOP/sql/wfmlrdbg.sql for a notification id and check the status of the message in WF_DEFERRED and WF_NOTIFICATION_OUT queue.
PROCESSED in WF_DEFERRED – The message is enqueued to WF_NOTIFICATION_OUT
PROCESSED in WF_NOTIFICATION_OUT – The message is sent as e-mail
READY in WF_DEFERRED – Check if Deferred Agent Listener is running
READY in WF_NOTIFICATION_OUT – Check if Notification Mailer is running
(v) Try rebuilding the WF_NOTIFICATION_OUT queue if necessary
The wfntfqup.sql script rebuilds the WF_NOTIFICATION_OUT queue by dropping and recreating
that queue, removing pending notification messages from the WF_DEFERRED queue, and
repopulating the WF_NOTIFICATION_OUT queue from the Oracle Workflow Notification System
Stop Notification Mailer, rebuild Mailer Queue using $FND_TOP/patch/115/sql/wfntfqup.sql.
(C) Inbound Processing not working
(i) Check the IMAP server
$AFJVAPRG -classpath $AF_CLASSPATH -Dprotocol=imap -Dserver=<IMAP Server> -Dport=143 \
-Daccount=workflow-<ORACLE_SID> -Dpassword=<workflow password> -Dconnect_timeout=120 \
-Ddbcfile=$FND_SECURE/<ORACLE_SID>.dbc -Dfolder=Inbox oracle.apps.fnd.wf.mailer.Mailer
(ii) Check if expunge to inbox is checked or Not
(iii) Login to the IMAP mailbox and cleanup any spam email if present. It is recommended to regularly cleanup the Process and discard folder
(iv) Create tag for the autoreply and delivery failure notification to avoid the continuous sending of the mails
(v) Ensure the Mailer inbound processing has been enabled by setting the mailer parameter Inbound thread count=1 and ensure that Notification mailer is up and running.
