Concurrent manager job scheduling management tools

Oracle Database Tips by Donald Burleson

Question:  I'm using Oracle eBusiness Suite and I have a scheduled concurrent manager job that I want to change from scheduled execution to on-demand execution.  How to I change the concurrent manager scheduling for a job?

Answer: I'm not an Oracle Applications DBA, but I did find these notes on concurrent manager task (job) scheduling.

Also see: Inside the concurrent manager and Concurrent manager scripts for more details

The Oracle Applications concurrent manager is a teleprocessing monitor (like Tuxedo or CICS) that allows jobs (database tasks) to be scheduled and single-threaded.  The concurrent manager uses the same job scheduling mechanisms as dbms_scheduler, and Dr. Hall's book "Oracle Job Scheduling" provides instructions for changing Oracle job execution status.

Running a concurrent manager job on-demand

There are several main methods for submitting a concurrent manager job, the concsub utility, the fnd_request command, dbms_scheduler and the ora_rw20_run executable.

Concurrent manager jobs with concsub

Oracle Applications provides the concsub utility (concurrent manager submit) procedure for submitting concurrent manager jobs on-demand and scheduling concurrent manager jobs.

CONCSUB Parameter Arguments:

<APPS username>/<APPS password> \ Required
<Responsibility Application Short Name> \Required
<Responsibility Name> \Required
<User Name> \Required
[WAIT=N|Y|<n seconds>] \Optional, Default value = N
<Program application short name> \Required
<Program Name> \Required[PROGRAM_NAME=?<description>?] \Optional
[REPEAT_TIME=<resubmission time>] \Optional
[REPEAT_INTERVAL=<number>] \Optional
[REPEAT_INTERVAL_UNIT=<resubmissionunit>] \Optional, Default = DAYS
[REPEAT_INTERVAL_TYPE=<resubmissiontype>] \Optional
[REPEAT_END=<resubmission end date andtime>] \Optional
[START=<Requested Start Date>]Optional, Default = Current time
[REPEAT_DAYS=<number of days>] \Optional
[IMPLICIT=<type of concurrent request> ] \Optional, Default = NO[PRINTER=<name of printer>] \Optional
[NUMBER_OF_COPIES=<number of copies>]Optional

Example invocation of concsub to submit a concurrent manager job:


Concurrent manager jobs with fnd_request

The fnd_request PL/SQL package can be used to trigger a concurrent manager request.  Here is the syntax:


Here is a PL/SQL example using fnd_request package and the submit_request procedure to submit a concurrent manager job:


v_request_id := fnd_request.submit_request(app_name,conc_pgm_shortname,description,paramers)

if v_request_id > 0 then

   dbms_output.put_line('Successfully submitted')
   dbms_output.put_line('Not Submitted');


Executing concurrent manager jobs with ora_rw20_run

You can also run a concurrent manager job on-demand with the ora_rw20_run OS command.  The example below is a Linux command to  start a concurrent manager job named 12345.  The backslash "\" characters are Linux multi-line command extensions:

root> ora_rw20_run \
   P_CONC_REQUEST_ID=12345 \
   p_unit="ABC' \
   p_region="NYC' \
   report=/u01/reports/myreport.rdf \
   batch=yes \
   destype=file \
   desname=/u01/reports/myfile.out \

Scheduling concurrent manager jobs with dbms_job and dbms_scheduler

All concurrent manager job are accessible via the dbms_job and dbms_scheduler interface.  For details, see Dr. Hall's book "Oracle Job Scheduling".

Changing Dispatching Priority within the Concurrent Manager

If there are requests that have a higher priority to run over other requests, you can navigate to

Concurrent --> Program --> Define

to change the priority of a request. If a priority is not set for a request, it will have the same priority as all other requests, or it will be set to the value specified in the user's profile option Concurrent:Priority.

If you like Oracle tuning, see the book "Oracle Tuning: The Definitive Reference", with 950 pages of tuning tips and scripts. 

You can buy it direct from the publisher for 30%-off and get instant access to the code depot of Oracle tuning scripts.
