Queries Related to Concurrent Requests in 11i Applications

Print this post

 

As part of day to day work, we need to use lot of queries to check the information about concurrent requests. Here are few queries which can be frequently used for day to day works and troubleshooting concurrent request / manager issues.
Note: These queries needs to be run from APPS schema.

Scheduled concurrent requests


Lot of times we need to find out the concurrent programs scheduled. Users can schedule the concurrent requests in three ways (To run once at a specified time / To run periodically / To run on specific days of the month or week).

The below query will return all the concurrent requests which are scheduled using any of the above methods:

SELECT cr.request_id,
DECODE (cp.user_concurrent_program_name,
'Report Set', 'Report Set:' || cr.description,
cp.user_concurrent_program_name
) NAME,
argument_text, cr.resubmit_interval,
NVL2 (cr.resubmit_interval,
'PERIODICALLY',
NVL2 (cr.release_class_id, 'ON SPECIFIC DAYS', 'ONCE')
) schedule_type,
DECODE (NVL2 (cr.resubmit_interval,
'PERIODICALLY',
NVL2 (cr.release_class_id, 'ON SPECIFIC DAYS', 'ONCE')
),
'PERIODICALLY', 'EVERY '
|| cr.resubmit_interval
|| ' '
|| cr.resubmit_interval_unit_code
|| ' FROM '
|| cr.resubmit_interval_type_code
|| ' OF PREV RUN',
'ONCE', 'AT :'
|| TO_CHAR (cr.requested_start_date, 'DD-MON-RR HH24:MI'),
'EVERY: ' || fcr.class_info
) schedule,
fu.user_name, requested_start_date
FROM apps.fnd_concurrent_programs_tl cp,
apps.fnd_concurrent_requests cr,
apps.fnd_user fu,
apps.fnd_conc_release_classes fcr
WHERE cp.application_id = cr.program_application_id
AND cp.concurrent_program_id = cr.concurrent_program_id
AND cr.requested_by = fu.user_id
AND cr.phase_code = 'P'
AND cr.requested_start_date > SYSDATE
AND cp.LANGUAGE = 'US'
AND fcr.release_class_id(+) = cr.release_class_id
AND fcr.application_id(+) = cr.release_class_app_id;

 
Note: The "SCHEDULE" column in the above query returns a string of zeros and ones for the requests which are scheduled on specific days of the month or week.

Positions 1 through 31: Specific day of the month.
Position 32: Last day of the month
Positions 33 through 39: Sunday through Saturday

Checking the duplicated schedules of the same program with the same arguments


The below query can be used to check the duplicated schedule of the same program with the same arguments. This can be used to alert the users to cancel these duplicated schedules.

Note: This query will return even though the request was submitted using a different responsibility.

SELECT request_id, NAME, argument_text, user_name
FROM (SELECT cr.request_id,
DECODE (cp.user_concurrent_program_name,
'Report Set', 'Report Set:' || cr.description,
cp.user_concurrent_program_name
) NAME,
argument_text, fu.user_name
FROM apps.fnd_concurrent_programs_tl cp,
apps.fnd_concurrent_requests cr,
apps.fnd_user fu
WHERE cp.application_id = cr.program_application_id
AND cp.concurrent_program_id = cr.concurrent_program_id
AND cr.requested_by = fu.user_id
AND cr.phase_code = 'P'
AND cr.requested_start_date > SYSDATE
AND cp.LANGUAGE = 'US'
AND fu.user_name NOT LIKE 'PPG%') t1
WHERE EXISTS (
SELECT 1
FROM (SELECT cr.request_id,
DECODE (cp.user_concurrent_program_name,
'Report Set', 'Report Set:'
|| cr.description,
cp.user_concurrent_program_name
) NAME,
argument_text, fu.user_name
FROM apps.fnd_concurrent_programs_tl cp,
apps.fnd_concurrent_requests cr,
apps.fnd_user fu
WHERE cp.application_id = cr.program_application_id
AND cp.concurrent_program_id =
cr.concurrent_program_id
AND cr.requested_by = fu.user_id
AND cr.phase_code = 'P'
AND cr.requested_start_date > SYSDATE
AND cp.LANGUAGE = 'US'
AND fu.user_name NOT LIKE 'PPG%') t2
WHERE t1.NAME = t2.NAME
AND t1.argument_text = t2.argument_text
AND t1.user_name = t2.user_name
GROUP BY NAME, argument_text, user_name
HAVING COUNT (*) > 1)
ORDER BY user_name, NAME 

Average pending time per request


This is a very useful query to check the performance of the concurrent managers.

Average pending time for a request is calculated like below:
("Highest of Requested_start_date or Date_submitted" - Actual_start_date ) / Total requests

A Request can be in Pending state for variety of reasons like conflict with other requests, improperly tuned managers (sleep seconds / cache size / number of managers etc)

We can schedule this script to gather data regularly for historical analysis as we normally purge the concurrent requests regularly.

SELECT TO_CHAR (actual_start_date, 'DD-MON-YYYY') DAY,
concurrent_queue_name,
(SUM ( ( actual_start_date
- (CASE
WHEN requested_start_date > request_date
THEN requested_start_date
ELSE request_date
END
)
)
* 24
* 60
* 60
)
)
/ COUNT (*) "Wait_Time_per_Req_in_Secs"
FROM apps.fnd_concurrent_requests cr,
apps.fnd_concurrent_processes fcp,
apps.fnd_concurrent_queues fcq
WHERE cr.phase_code = 'C'
AND cr.actual_start_date IS NOT NULL
AND cr.requested_start_date IS NOT NULL
AND cr.controlling_manager = fcp.concurrent_process_id
AND fcp.queue_application_id = fcq.application_id
AND fcp.concurrent_queue_id = fcq.concurrent_queue_id
GROUP BY TO_CHAR (actual_start_date, 'DD-MON-YYYY'), concurrent_queue_name
ORDER BY 2

Note: Depending on the purging schedules some requests might miss if the corresponding data in fnd_concurrent_processes is purged.

Checking which manager is going to execute a program

The below query identifies the manager which will be executing a given program. This query is based on the specialization rules set for the managers.

SELECT user_concurrent_program_name, user_concurrent_queue_name
FROM apps.fnd_concurrent_programs_tl cp,
apps.fnd_concurrent_queue_content cqc,
apps.fnd_concurrent_queues_tl cq
WHERE cqc.type_application_id(+) = cp.application_id
AND cqc.type_id(+) = cp.concurrent_program_id
AND cqc.type_code(+) = 'P'
AND cqc.include_flag(+) = 'I'
AND cp.LANGUAGE = 'US'
AND cp.user_concurrent_program_name = '&USER_CONCURRENT_PROGRAM_NAME' AND NVL (cqc.concurrent_queue_id, 0) = cq.concurrent_queue_id
AND NVL (cqc.queue_application_id, 0) = cq.application_id
AND cq.LANGUAGE = 'US'

To see all the pending / Running requests per each manager wise

SELECT request_id, phase_code, status_code, user_name,
user_concurrent_queue_name
FROM apps.fnd_concurrent_worker_requests cwr,
apps.fnd_concurrent_queues_tl cq,
apps.fnd_user fu
WHERE (cwr.phase_code = 'P' OR cwr.phase_code = 'R')
AND cwr.hold_flag != 'Y'
AND cwr.requested_start_date <= SYSDATE
AND cwr.concurrent_queue_id = cq.concurrent_queue_id
AND cwr.queue_application_id = cq.application_id
AND cq.LANGUAGE = 'US'
AND cwr.requested_by = fu.user_id
ORDER BY 5

Note: The same information can be seen in Administer Concurrent Manager form for each manager.

Checking the incompatibilities between the programs


The below query can be used to find all incompatibilities in an application instance.

SELECT a2.application_name, a1.user_concurrent_program_name,
DECODE (running_type,
'P', 'Program',
'S', 'Request set',
'UNKNOWN'
) "Type",
b2.application_name "Incompatible App",
b1.user_concurrent_program_name "Incompatible_Prog",
DECODE (to_run_type,
'P', 'Program',
'S', 'Request set',
'UNKNOWN'
) incompatible_type
FROM apps.fnd_concurrent_program_serial cps,
apps.fnd_concurrent_programs_tl a1,
apps.fnd_concurrent_programs_tl b1,
apps.fnd_application_tl a2,
apps.fnd_application_tl b2
WHERE a1.application_id = cps.running_application_id
AND a1.concurrent_program_id = cps.running_concurrent_program_id
AND a2.application_id = cps.running_application_id
AND b1.application_id = cps.to_run_application_id
AND b1.concurrent_program_id = cps.to_run_concurrent_program_id
AND b2.application_id = cps.to_run_application_id
AND a1.language = 'US'
AND a2.language = 'US'
AND b1.language = 'US'
AND b2.language = 'US'

The table apps.fnd_concurrent_program_serial has the information about incompatibilities.
