=============================================== 

When i see the Status OPP Manger and Workflow Mailer from Concurrent–>Manager–>Administer Screen. I see below status
oppwf
Solution :
• Ensure Concurrent:GSM Enabled profile is set to ‘Y’
• Verify Service Manager status in Administer Form.
• Verify Service Manager Definition.
• Ensure FNDSM Entries available in FND_CONCURRENT_QUEUES Table
• FNDSM entry should be correct in Tnsnames.ora file and tnsping  FNDSM_hostname should work fine.
• Then Bounce the Services.

Concurrent Processing – R12 Output Post Processor Service Not Coming Up:

------------------------------------------------------------------------------

Reason :
If Service Manager for the node is not running.  Possible cause might be service manager definition is missing under
Concurrent ->Manager ->Define form. If the Service Manager is not present/defined for a particular node,then this causes all the services provided by Service Manager like OPP,WF etc.. not to work.
1. Shutdown all the services.
——Below Step 2 will create  Service Manager “FNDSM”——-
2. Log in as applmgr
cd to $FND_TOP/patch/115/sql
Run the script: afdcm037.sql
3. Relink FNDSM and FNDLIBR executables as mentioned below:
$ adrelink.sh force=y link_debug=y “fnd FNDLIBR”
$ adrelink.sh force=y link_debug=y “fnd FNDSM”
4. Run cmclean.sql
5. Start up the managers/services
