OWB Workflow Queue Listener

Hi ,
We are trying to schedule the OWB 3i mappings using OEM 2.2 and Workflow 2.6.2.We have a queue listener 'workflowqlsnr.bat' on the client side,but we need to have the Workflow Queue Listenter on the Server side.Please let me know what is the procedure in order to deploy the listener.sh in the server(Unix).
I have the following file installed in my owb3i\owb\bin\solaris directory on Windows 2000 -- workflowqlsnr.sh,workflowqlsnr1.sh.
Environment:
OWB 3i Client ( Windows 2000).
Server OS: Sun Solaris
Database : 8.1.7.3
OEM 2.2
OWF 2.6.2 Server/Client.
Thanks for the help.

I wants to use the scott database( default database given by oracle ) as my input source.
How can I create the DB LINK ( for scott database) ?
How can I create the DB LINK ( for any other database) ?
Should I need to add anything in Setting of"ODBC DATASOURCE ADMINISTRATION"
==================
Settings done:
==================
DB Link Name :prashant

This is not actually a Workflow component, this is part of the Oracle Warehouse Builder product, although the name is similar to the Workflow Agent Listener in v2.6.

Oracle Workflow WF_IN Listener doesn't dequeue message


I'm using Oracle Interconnect 10g (ver. 10.1.2.2) and has been struggle trying to make the workflow WF_IN listener to work and have no luck so far.


I have done the following: 
1. Create a Service Components for Workflow Inbound Listener from Oracle Application Server Control 10g. 
2. Create WF_IN Listeners from Oracle Workflow Setup Check All homepage 
3. Create 3 Event Subscriptions from Oracle Workflow homepage: 
a. Event: oracle.apps.wf.event.agent.create 
b. Event: oracle.apps.wf.event.event.create 
c. Event: oracle.apps.wf.event.subscription.create 
4. Create Oracle Workflow Publish and Subscribe Activity Event from iStudio and deploy them to Oracle Workflow


Regardless, the message that is in WF_IN Queue is always in ready state (state 0) and never dequeued. I have no idea what steps am I missing here. It just seems that the listener I created doesn't work or maybe not configure properly. So, if anybody can help me out here, I really appreciate. Here is the screenshot of the configuration I mentioned above.

Thanks,

Edward, you see, when you create WF_IN Listener from Oracle Workflow Setup Check All homepage, really they implemented as database JOBs.
So, connect to database as sys and select from DBA_JOBS, look if there is any job with text ("what" column) like "Wf_Event.Listen('WF_IN')".
If there is one or several - check there status, if they are working correctly (broken = 'N', failures = 0).
If broken = 'Y' or failures > 0, than you have problems with them!
In this case check if you have set database parameters job_queue_processes=10, and aq_tm_processes=1 as recommended for Workflow.
If it does not help, try to execute dequeue comment manually:
begin
Wf_Event.Listen('WF_IN');
end;
Good luck!

Workflow Agent Listener Service - Performance tuning for high volume

We have AR and Collection which initiate thousands of workflows. We also have various other workflows that run parallell activities. We have workflow backgrond engine schedule as Y,N,N for each of the item types.
It takes many hours for the workflows to progress. In some cases the background engine stays running on the current manager for hours when it reaches flow steps that take longer. It looks like the Workflow Agent Listener Service processes a single flow at one time which is killing us when longer running processes are running. We run 1 Workflow Agent Listener Service with 30 threads assuming it would pick up and process 30 items. It is very hard to tell if we have improvement.
Does anyone have any information on the following-
1) is it better to have more than 1 Workflow Agent Listener Service or is 1 sufficient?
2) is there a benefit to having multiple threads?

Please mention the details of the application release, database version and OS.
Can you find any errors in the workflow/database log files?
Any locks in the database?
Please see these doc.

Workflow Agent Listener and Workflow Background program run after each minute

Hello,
We have scheduled Workflow agent listener program to be run after 5 minutes but it runs every minute more than once and fills concurrent request queue.
Please help.

Thanks & Regards

We have scheduled Workflow agent listener program to be run after 5 minutes but it runs every minute more than once and fills concurrent request queue.
Looks like this concurrent program was scheduled to run more than once? Maybe under a different application user?
What if you cancel the recent schedule you made, would you be able to reproduce the issue then?

Hi ,
What is your OWB version ?
If it is 10.2 then read the following
With Warehouse Builder 10.2.0.X, the Repository Browser Listener is only supported on Windows x86-32bit and linux x86-32bit client machine.
So start the Warehouse Builder Repository Browser Listener on Windows/Linux x86-32bit client machine
For 11g refer MOS Note 469422.1

OWB Workflow Help

Im conducting a proof of concept using OWB Workflow version 2.4. To give some background, the objective is to run numerous dependant SQL scripts that in effect hand craft the ETL process, at a pre-scheduled time, that provide logging and re-starting functionality.
With the distinct lack of publications and documentations Id appreciate any feedback anyone may have on the following:
1) Is it possible to restart a process at a step midway through the flow. For example the 3rd SQL Activity step out of 10 may have failed and instead of starting over, its a requirement to re-start the step that failed.
2) I've read that Oracle are rumoured to be de-supporting the workflow functionality, if so then what is their proposed method of scheduling and controlling ETL jobs.
3) Can a log file generated by the SQL Plus activity be attached to the failure or success email activity?
Any input would be appreciated, also any pointers to OWB publications or documentation, other than the Oracle manuals of course.
Thanks in advance
James

We have been working towards something similar, and the approach we have settled on is as follows:
1) We have added our own runtime-audit tables which track the most recent process flow run date, final status, and the completion status of each mapping. So, a new run can see if a) this run is a restart, in which case we set our max date for drawing data over to be the run date of the last run, and b) what mappings ran succesfully. This way, a function called needs_to_run(mapping_name varchar2) returns a true/false answer to see if a given mapping needs to be executed on this run. The logic is pretty simple
if run_type is full_run or (run_type is restart and nvl(last_run_status,'FAILURE') of this mapping is 'FAILURE')
then
return true;
else
return false;
2) We do not use mapping objects in the process flows. We will only use SQL*Plus objects that do something like this:
variable exec_return_code;
declare
retVal varchar2(30) := 'OK';
begin
if needs_to_run('ThisMapping') then
ThisMapping.main(retVal);
end if;
:exec_return_code := retVal;
exception
when others then
:exec_return_code := 'FAILURE';
end;
exit :exec_return_code
So that each mapping will check first to see if it needs to execute before running thus skipping over fully completed mappings in the case of a restart. As to emailing log information, we currently do that in our post-mapping procedures in the event of a failure rather than logging to file and then attaching to email. We also have a last step that emails a summary of our audit info for each mapping run - but again this is all done inside pl/sql rather than spooling to file.
Anyway, just some ideas to toss your way. And no, we haven't yet got it all completed and working yet, but it is coming along nicely and none of our individual proof-of-concept tests have provided us with any show-stoppers thus far.
Cheers,
Mike

OWB workflow question

I'm an OWB-newbie (using PARIS) and have a question about OWB workflows.
I want to create several mapping workflows.
All the mapping workflows should send a mail with the outcome of the workflows (success, error, warning) to an administrator.
I don't want to always code the same mail activity with the same parameter values.
So my idea is to write one subprocess which handles the mail-routine with some input parameters (calling workflow-name, process state (success, warning, error)).
In the subprocess I want to test the input parameter "process-state". If the value is 0 (success) then a mail with the workflow name as subject should be generated incuding an static text e.g. "mapping successful". If the value is 1 then "mapping warning" and so on.
What OWB activity has to be choosen for testing the input parameter "process-state" like an if-then-else construct or a case-construct?
How can the value of the input parameter "workflow-name" be included in the mail-body?
Regards
Martin

To my experience, using the OWF for these things is not very practical. I would suggest that you would make your own PL/SQL procedude that does this, and then call that procedure from within the actual mapping (post-mapping), using the values you have there.
This might not be what you want, however. I simply find the email capabilities of OWF too limited for actual work.

Error Starting OWB Rep Browser Listener

Trying to start the OWB Repository Browser Listener, on a Win XP client (11g/11g), via StartOwbbInst.bat, and I receive the following error:

Either the %ORACLE_HOME% token included in the ref'd file name is munged in logging, or the app is actually trying to ref a file with an %ORACLE_HOME% literal. I see no issues with any environment settings, or with any env assignments in either the StartOwbbInst.bat or the ref'd setowbenv.bat file.
Any ideas would be mucho appreciated!

Start OWB workflow from APEX

Hi together,
My challenge is to start an OWB workflow from an apex procedure.
Procedure:
declare
numb number;
audit_id number;
begin
numb := rtruser_blueprint.exec_api.execute('LOC_A014_OWF_MGR', 'PROCESS', 'LOAD_CALM_DELIVERY', ',', 'DELIVERY_ID_IN=6', audit_id);
end;
My problem is the following error:
ORA-06565: cannot execute SET ROLE from within stored procedure
This error occures at the following row in the execute-Procedure in the package exec_api (standard owb execution package):
dbms_session.SET_ROLE('OWB_D_rtr10201_blueprint');
dbms_session.SET_ROLE('OWB_O_rtr10201_blueprint');
If I run this script directly with sqlplus, the procedure works fine. As a result of this, I assume, the problem has to do with the grants which the apex execution user (APEX_PUBLIC_USER) doesn't have in contrast to the blueprint user (which is schema owner)
More informations about the environment setup:
The apex workspace is bound to the database - user: BLUEPRINT.
BLUEPRINT has the grant to execute the procedure 'EXECUTE' in the package 'EXEC_API'. The 'EXEC_API' package belongs to the user 'RTRUSER_BLUEPRINT'.
My concrete question is: Which rights / grants does which user need to execute the procedure directly from APEX?
Thanks for your help!
Mirco

What account were you using when you ran the 'execute_api' procedure from SqlPlus ? Also, all SQL and PL/SQL from APEX is executed as the application's parsing schema id and not the schema used by APEX to connect to the database.

Calling owb workflow job created in oem using pl/sql

Configure the Database for FTP in an OWB workflow

I want to use the ftp-operator in an OWB-Workflow. I want to use a script, that is managed in the owb itself.
I configure the ftp operator in this way:
COMMAND: /usr/bin/ftp (i can start the command at the command line)
PARAMETER_LIST: ?"${Task.Input}"?
SUCCESS_THRESHOLD: 0
SCRIPT: [my with the ftp Commands]
After the execution of the workflow i get the error message: "/usr/bin/ftp -n: not found"
in Runtime Audit Browser
Does anybody know what i have to do to get the ftp operator running?
The operating system of the database server is HP UX.
Thanks in advance
Alexander

Hi,
why do you want to use ftp? As against going directly to the source database? (So much faster and easier). I haven't used ftp since the last century.
