Purge Concurrent Request and/or Manager Data Program(FNDCPPUR) effect which tables


Tables that are updated when Purge Concurrent Request and/or Manager Data Program Program( FNDCPPUR) is started:

FND_CONCURRENT_REQUESTS
This table contains a complete history of all concurrent requests. This table should ideally be kept at around 4 - 5k records and should be regularly purged as part of normal 'housekeeping' by running the standard FNDCPPUR program. This is a part of basic system administration and it is recommended that for the average instance, it should be run every 30 days or so. Allowing the table ( and others ) to increase in size can affect performance.

FND_RUN_REQUESTS
When a user submits a report set, this table stores information about the reports in the report set and the parameter values for each report.

FND_CONC_REQUEST_ARGUMENTS
This table records arguments passed by the concurrent manager to each program it starts running.

FND_DUAL
This table records when requests do not update database tables.

FND_CONCURRENT_PROCESSES
This table records information about Oracle Applications and operating system processes.

FND_CONC_STAT_LIST
This table collects runtime performance statistics for concurrent requests.

FND_CONC_STAT_SUMMARY
 This table contains the concurrent programperformance statistics generated by the Purge.

FND_ENV_CONTEXT
This table stores information about environment name and value for each of the concurrent process


To avoid running out of space on your disk drives, you should periodically
delete Oracle Applications log files, output files and purge these tables
with the FNDCPPUR program.

The FNDCPUR purge program maintains the number of log and output files the
the operating system retains, and manage tables that store information about
concurrent requests and concurrent manager processes.

You can run the program FNDCPPUR once and automatically resubmit the program
for your specific time intervals.


- Every 30 days for normal usage.
- Every two weeks (14 days) for heavy usage.
- If are using the AGE mode, set the Mode Value to 7 or higher to retain the most recent days of concurrent request data, log files, and report output files. For optimum purging, the request could be scheduled to run on a daily basis off-hours using the AGE that best meets the business needs.


WARNING:When you purge concurrent request information, you lose audit details which are used by the Signon Audit Concurrent Requests report.

FNDCPPUR Program options:
ENTITY = AL : Purge of concurrent requests, concurrent managers, request log files, manager log files and report output files. The following tables are purged
-  Fnd_Concurrent_Processes
-  Fnd_Dual
-  Fnd_Concurrent_Requests,
-  Fnd_Run_Requests
-  Fnd_Conc_Request_Arguments
-  Fnd_Dual
-  Fnd_Context_Env
-  Deletes concurrent requests' log and out files from OS

ENTITY = MANAGER: Purge of concurrent managers and manager log files.
The following tables are purged
-  Fnd_Concurrent_Processes
-  Fnd_Dual
-  Deletes concurrent manager log files from OS

ENTITY = REQUEST: Purge of concurrent requests, request log files, and output files.
The following tables are purged
- Fnd_Concurrent_Requests,
- Fnd_Run_Requests
- Fnd_Conc_Request_Arguments
- Fnd_Dual
- Deletes concurrent requests' log and out files from OS


Mode:
 AGE: The number of days for which to save concurrent request history.
COUNT” Number of records
Mode Value: valid values are 1 - 9999999
User Name: application username
Oracle ID: Oracle ID
Program Application:   application
Program: program
Manager: application associated with the concurrent manager
Manager: concurrent manager
Resp. Application:   application associated with the responsibility
Responsibility:   responsibility or "All".
Report: No       Run the program but do not generate a report.
Yes      Run the program and generate a report.



Note:
The following tables can also be purged depending on the parameters being used:
FND_FILE_TEMP
FND_CRM_HISTORY
FND_TM_EVENTS
FND_TEMP_FILES
FND_CONFLICTS_DOMAIN
Also the linked tables of
FND_CONC_REQUEST_ARGUMENTS
FND_CONC_PP_ACTIONS
FND_RUN_REQ_PP_ACTIONS
For example, the 'Purge other' parameter has the following function:
No => Do not delete records from FND_DUAL.
Yes => Delete records from FND_DUAL.
