OPP runs as a service that can be managed through Oracle Applications Manager (OAM) from the System Activity page (Navigation: Applications Dashboard > Applications
Service (from the dropdown list) > Go).
How to Increase the number of Output Post Processors?
1.Log on to Applications with “System Administrator” responsibility.
2.Navigate to Concurrent -> Manager -> Define.
3.Query for the “Output Post Processor” service.
4.Click on “Work Shifts” and increase the number of processes
How to get OPP manager log file location?
$APPLCSF/log/<SID>/FNDOPP####.txt OR
1,System Administrator > Concurrent > Manager > Administer
2,Search for ‘Output Post Processor’
3,Click the ‘Processes’ button .
4,Click the Manager Log button. This will open the ‘OPP’
Upload the OPP log file.
In some cases, Output Post Processor is not starting up and it shows Actual and Target are showing different values when we query for Output Post Processor.
The log files shows that no error message.In this case apply the following possible solution for starting the OPP.
1. Shutdown the internal manager by using adcmctl.sh stop apps/apps
2. Make sure there is no FNDLIBR processe running:
$ ps -ef| grep FNDLIBR OR ps -ef|grep applprod|grep FNDLIBR
3. If there is any FNDLIBR processe please kill it $ kill -9 pid
4. Run cmclean.sql script as document from Note 134007.1
5. Restart the internal manager by using adcmctl.sh start apps/apps
or How to kill and start Output Post Processor (OPP) Background:
This article explains how to kill OPP and restart the same
Solution:
1,System Administator > Concurrent > Manager > Administer
2,Query “Output Post Processor” -> Processes button
Get the sytem id of “Output Post Processor”
3,ps -ef|grep [system id]
4,kill -9 [system id] in Unix
5,System Administator > Concurrent > Manager > Administer
6,Query “Output Post Processor” -> Restart button
Fixing Output Post-processor actions failed issues in EBS R12
Environment: Oracle EBS 12.1.3, Oracle Database 11gR2, RedHat Linux5
Symptoms:
Users unable to open the out files.
Concurrent requests failed with “Post-processing of request failed error message”
One or more post-processing actions failed. Consult the OPP service log for details.
No further attempts will be made to post-process this request.
Cause:
The concurrent manager process was able to successfully invoke the Output Post-Processor (OPP) but encountered a timeout as the OPP takes longer than the value
assigned to complete the job.
Solution:
1,Increase the value of profile Concurrent: OPP Response Timeout . Bounce Apache and retest.
2,If the issue still exists, perform the following steps.
3,Increase the number of Output Post Processors as follows:
4,Increase the number of processes for Output Post Processor.
5,Additionally, ensure there is a setting of oracle.apps.fnd.cp.opp.OPPServiceThread:2:0:max_threads=5 under Parameters.

Concurrent Requests Fail Due to Output Post Processing (OPP) Timeout [ID 352518.1]
Ouput Post Processing Fails Due To java.lang.ThreadDeath [ID 427233.1]
Why Does OPP Intermittently Completes With Warnings and Error ‘java.lang.OutOfMemoryError’? [ID 978495.1]
How to start the Output Post Processing (OPP) in 11i
At least one OPP process active in the system. The concurrent processing uses the Output Post Processor (OPP) to enforce post-processing actions for concurrent requests. For example, post-processing action is that used in publishing concurrent requests with XML Publisher.
Actually when you have submit a request with XML Publisher template specified as a layout for the concurrent request output. Once finishes the concurrent manager concurrent program, it will contact the OPP to apply the XML Publisher template and create the final output
To activate the OPP follow these steps
The Profile Option “Concurrent: GSM Enabled” must be set to Y
Then:
1. Login to Apps with sysadmin responsibility
2. Navigate to: Concurrent -> Managers -> Define
3. Query for
Manager = ‘Output Post Processor%’
or Short Name = FNDCPOPP
4. Check the checkbox “Enable” .
5. Click on ‘Work Shifts button
6. see Work Shift of the OPP and
Set Processes = 1
and Parameters = oracle.apps.fnd.cp.opp.OPPServiceThread:2:0:max_threads=5
and Sleep Second = 30
7. Save
How to restart Oracle Apps 11i OPP via non unix command
It can be done using adcmctl.sh script only and there is no specific script for OPP. You can restart it from the application via (System Administrator responsibility > Concurrent > Manager > Administer), select “Output Post Processor” and click on the “Restart” button.
OPP Issue while generating the XML Output in apps 11i
Problem Description:
1, Few XML type concurrent programs taking long time and completed with warning OPP log file registered below error
Caused by: java.lang.ThreadDeath
2, CPU utilization taking 100% constantly while running the concurrent programs.
Cause
The java.lang.ThreadDeath error indicates that the Output Post Processor has reached its processing timeout.
Solution
The following configuration changes are recommended to optimize the environment for these type of reports:
1. Increase the value of the Concurrent: OPP Timeout profile option to 10800 seconds.
2. Enable the scalability feature of XML Publisher:
1. Login as SYSADMIN
2. Responsibility: XML Publisher Administrator
3. Function: Administration
4. Set the following properties:
5. Temporary Directory
6. Use XML Publisher’s XSLT processor: True
7. Enable scalable feature of XSLT processor: True — By default it’s false
8. Enable XSLT runtime optimization: True
> After changing the value also the problem still exist. As per the SR suggestion, we increased the java heap size from 1024M to 2048M.
a. Bring down the concurrent managers.
b. Use the Update statement below, for example:
update FND_CP_SERVICES
set DEVELOPER_PARAMETERS =
‘J:oracle.apps.fnd.cp.gsf.GSMServiceController:-mx2048m’
where SERVICE_ID = (select MANAGER_TYPE from FND_CONCURRENT_QUEUES
where CONCURRENT_QUEUE_NAME = ‘FNDCPOPP’);
c. Bring concurrent managers up again
