Oracle Workflow Monitor

I've seen plenty of references to Oracle Workflow Monitor, but I've never paid much attention. Yesterday I got an error message from Control Center that instructed me to use Oracle Workflow Monitor to solve my problem (a process was running and needed to be shut down before regenerating).
But how to I use Oracle Workflow Monitor? Is it installed by default when OWF was initially installed with OWB? What URL do I use access it? If it does not run after the conventional OWB install, is there a How-To document available for configuring it?
To be clear, OWF seems to be set up and working. I have created and run process flows successfully. I've just experienced a weird problem that Control Center cannot seem to handle -- and I'm looking for answers. Frankly, I'm mystified at the lack of information on Oracle Workflow Monitor given that OWB error messages reference it and plenty of people seem to discuss it in technical forums.
Thanks,
David

Thanks Robert!
We are using OWB 11 on Oracle 11, but I'm going to press on and ask our DBA to install the OWF mid-tier components from the 10g Companioin CD. I don't think workflow has changed and so I'm hopeful.
(If anybody has experience, please chime in for the record.)
Thanks again!

Oracle Workflow Internal Forced termination Error

We will appreciate if anyone can be of assistance in helping us with a problem we are experiencing with Oracle Workflow.
We have an Oracle Workflow Task which has several activities.
This exact version of the Workflow works in 2 other environments, with the exception of the current environment where we are experiencing the issue described below.
1.     The Oracle Workflow Task is submitted via the Oracle Workflow monitor: Launch Processes
2.     The Task terminates internally immediately after submission ***
3.     The report result status on the first activity indicates “Force”
4.     The overall Workflow reports result status indicates “Failure”
5.     The first activity normally executes for 12 minutes before executing the next activity, we can see the process executing on the database level (Performing database steps as expected – logging to an audit table 6 times)
6. The follow on activity never gets executed.
We believe that this is an environment issue. Out application stack is:
1.     Oracle Database 9.2.0.5
2.     Oracle Workflow 2.6.2
3.     Oracle warehouse builder 10g R2
Thanks for any help in resulving this.

Hi,
We have just had a similar problem, also when trying to deploy a process flow module.
After investigating the contents of the WF_ITEM_TYPES table we noticed that an entry allready existed with the same Name as the Process Flow Module that we were trying to deploy.
To fix this we simply renamed the Mapping and reran the deployment, with sucess.
We belive that a previous failed deployment of the Process Flow Module (due to a missing language), left the Database in an inconsistent state, renaming the flow meant that the PK was no longer broken, however the half finished deployment has probably left further rubish in the system.... we will see :-)

RPE-02062 Workflow Monitor

When I try to re-deploy an updated Process Flow, it fails with the following error:
"RPE-02062: ItemType MERGERAW cannot be dropped as it has running processes. You must first abort all the running processes using the Oracle Workflow Monitor".
I have only installed OWF to use with OWB, and don't even think I have an Oracle Workflow Monitor! I located a session with username OWF_MGR and killed it. I have even rebooted the server, but the OWF_MGR session keeps coming back.
How else do I abort these running processes?

Looking back at my installation notes for Oracle Workflow, I found that I could access the Oracle Workflow web services from the following URL
"http://<server_name>[:<port>]/pls/OWF_DAD/wfa_html.home" where OWF_DAD is the Data Access Descriptor defined during installation. If you connect using the owf_mgr user name / pwd that was created when installing OWF then the browser window displays "Oracle Workflow" and a list of hyperlinks. One of these is "Find Processes". Following this link and clicking the 'Find' button with Item Type=All selected, shows a list of process names and their status. From there I was able to see the process flow that was causing the problem and abort it. Deploying the process flow from OWB then worked smoothly.

Unable to View Monitor Diagram in Oracle Workflow 2.6.5

Hi
When I click 'View Diagram' button in Oracle Workflow in Internet explorer, a blank grey page is displayed. I get following error in java console:
Error loading class: oracle.apps.fnd.wf.Monitor
java.lang.NoClassDefFoundError
java.lang.ClassNotFoundException: oracle.apps.fnd.wf.Monitor
     at com/ms/vm/loader/URLClassLoader.loadClass

     at com/ms/applet/AppletPanel.run
     at java/lang/Thread.run
But jar file wfMon.jar is present in OA_JAVA path. It contains Monitor class.
Does anyone know how to resolve this?

Yes, index.html is not relevant, just use it to make absolutely sure noone is able to browse virtual paths, as well as for testing that the virtual mapping is correctly defined..
I struggled with this as well, the only thing I can suggest is that you check a few things:
1. Are you sure that you don't have 2 /OA_JAVA/ definitions in your apache config files, so that the one that apache uses points to a different place than where you have placed your files?
2. Are you absolutely, definitevily sure that you haven't made a typo in your virtual path definition (I did, and it took me an hour to find the error...)?
Check this by putting a html file in the directory, and try to open this directly in your browser (http://yourserver.com/OA_JAVA/index.html), to make sure you don't get a "404 Not Found" http error.
3.
a) Make sure that you got the slashes then correct way, depending on your platform..
b) Make sure to get the capitalisation correct, especially on unix/linux, but possibly this is important in windows as well, as java is case-sensitive too.
c) Make sure you include the trailing slash at the end.
d) Make sure you restart http server after modifications, and if you manually edit a config file you need to run dcmctl updateConfig (this is not necessary if you edit from within the EM Website).
e) Make sure to clear your browser cache and start an entirely new IE browser after every modification (this is important!).
These definitions should work (note the trailing FORWARD-slash):
Windows:
Alias /OA_JAVA/ D:\myfolder\wf\java/
Unix/Linux:
Alias /OA_JAVA/ /myfolder/wf/java/
Go through your config once more, and let us know if you are able to view the html-file on the http://yourserver.com/OA_JAVA/index.html url (of course substituting with your server:port).
Hope this helps..

Workflow Monitor Drill Down

Hi,
Not sure if this problem is related to the OWB team, but
would definitely need to know if this has been experienced before.
We have OWB 9.2 running on a Oracle 9i R2 Database (9.2.0.5) with workflow 2.6.2. We have process flows
deployed and running properly. In the Workflow Monitor
we are not able to drill down to the sub process for some
reason. When we double click on the process, it dosen't
do anything. Normally, Workflow allows the drill down
to the sub process.
Is this a restriction of OWB by any chance ?
Any tips would be greatly appreciated.
Rgds,
Sri

Hello, I have the same versions of OWB and Workflow. I observed this very behaviour, and explained it noticing that the subprocesses are really functions which call the processes. A process MYSUBPROCESS is called by a function named something like @MYSUBPROCESS, so I think it's impossible to drill down. In fact in the Monitor if you click on a sub process, the activity type is equal to "function" in the Definition tab -- instead of "process".

Oracle WorkFlow Server (Middle Tier Components)

To OWB Gurus,
I'm trying to install Oracle WorkFlow Server to create Process Flows and Schedule for the ETL mappings that I have. When tryin to install WorkFlow Server, it specifies to install Middle-Tier Components. My question is for creating the WorkFlow Process and Scheduling do I need to have the Middle-Tier Components installed? Can I create the flows without the middle tier components ?
-AW

You can deploy and run processflows without OWF middle-tier,
but this component (Workflow monitor) is very helpful for monitoring and control of processflow

OWB 11g2 & Oracle Workflow

Hi all,
We are trying Warehouse Builder 11g2 and also database 11g2. He have seen it works fine, but we algo have seen that Oracle Workflow it is not supported in this database version, and from Oracle recomends using BPEL.
Is this true? What will we have to install? The way of develop is the same with BPEL?
Thanks in advance

Is this true? What will we have to install? The way of develop is the same with BPEL?As I know OWB11gR2 doesnt support direct deployment processflows to BPEL.
Oracle Workflow server supplied with Oracle database 11g R2 (it installed with OWB, directory for WF is ORADB_HOME/owb/wf).
If you used Workflow monitor you can install it from Oracle database 10g R2 CD.

Oleg

Workflow monitor ?

Hi Folks,
I have installed workflow server 2.6.4.( I am using OWB 10g R2 which is accessing Oracle 10g Enterprise edition R2). I have installed workflow middle tier too successfully. I was told that installing workflow middle tier will help in better monitoring the process flow.I have downloade and installed workflow client too.
I am unsable to find 'workflow monitor' for which I went through the above exercise. Can anyone point me in right direction so as I can start using workflow monitor to analyse/monitor my process flows.
Thanks

Hi,
look at http://<machine-name:7777>/pls/wf/wfa_html. You must log on as the workflow-owner which you had configured after installing the workflow server.

Oracle Workflow Java API

Hi everyone,
some questions to that API (maybe only Oracle can answer):
1) in the "Oracle Workflow and Java Technical White Paper" an API-Function called "setItemOwner" ist described but you cannot find this method inside any class of the wf*.jar files. Where is it ?
As i understnd, the owner of a workflow-item(process) is needed to watch the processes with workflow-monitor.
Do we have to implement this function/method ?
2) I found out, that the Java API is, compared with the PL/SQL packages, slightly incomplete?
Several functions/methods are not implemented and other functions/methods are not of the same functionality as their PL/SQL counterparts.
An Example: CreateProcess
The Java method "createProcess" has two parameters fewer (user_key and owner_role). API methods to set the user key or to set the owner (see Question 1) are not implemented.
Is there a special reason for that ?
Thanks
Ralf

Ralf,
1) setItemOwner should be in the WFEngineAPI class in the package oracle.apps.fnd.wf.engine.
2) It is true that the Java and PL/SQL implementations are not exactly the same - some APIs are available only in PL/SQL, others only
in Java. The Workflow Guide lists which ones are currently available where. If there is functionality you would like to see added, I
think the best thing to do is log an enhancement request.

Clara

Oracle WorkFlow, help me, please

Hi,
I don't familiar with Oracle Workflow , I want to use it, in fact I build up the Oracle WorKFlow using WorkFlow
Builder but I don't know how to link the workflow process with the aplication.
Can any one tell me How to execute this work flow
regards
Marma Teresa

Hello Maria,
There are two parts to your question; First, if you want to see how Workflow works in the application a good idea would be to test for example; a Purchasing Workflow. If you have Purchasing do the following: (I'm not sure how your setup is for the apps. so I'll include all steps).
1) Create yourself as a user in the Core applications: (R) System Adminstrator - (N) User/
Define
2) Give yourself the following responsiblities: a) System Adminstrator
b) Purchasing
c) Workflow Adminstrator Web Applications
3) Create a Purchase order in Purchasing - do not approve the PO
4) Open a SQL session and run the following script:
SQL> select segment1, wf_item_type, wf_item_key,po_header_id
from po_headers_all
where segment1 = <PO Number>;
This script will give you the the name of the workflow that got called: wf_item_type and
the unique instance of the definition that got called: wf_item_key.
5) Choose the Workflow Adminstrator Web Applications responsibility and choose Find Process
from the menu
6) In the Item key field enter the value from the SQL script (wf_item_key) - click on Find
7) In the next form chose the View Diagram button - this will launch the Workflow Monitor, it
will allow you view the present state of the definition - the green line indicates
the 'path'Workflow has taken and the color also indicates that everything is ok.
8) Go back into Purchasing and Approve the PO
9) Follow steps 5,6 and 7 - to see the 'continued flow' of the Workflow.
The second part to your question, if you have created a Workflow you have two options;
1) To actually 'call' the Workflow you created, you will have to save your definition to the
database. Chose the Launch Process menu, find your definition. The in the next form, enter
the data for your attributes...then click ok. This will launch your workflow.
Unfortunately, I do not know what your definition looks like so may encounter some errors.
But the Launch Process allows you 'test' the Workflow you created.
2) If you want to 'include' your definition in the Core Applications that might require a
customization. In brief, when users are in the application, depending on what they are
doing, the form will call workflow. If you want the application to call your definition you
will have to cutomize the call the form makes. But, certain modules in the application
do allow you to modify Oracle's definition and call your new process - Oracle Purchasing
is one of those modules.
I hope this information helps. If you need more infomation let me know: [email protected]
Thanks,
Karen

Oracle workflow server with linux

In "10g Release 1 (10.1.0.4) Patch Set 2 for Linux x86 Patch Set Notes", it is mentioned that modplsql is not currently supported on Red Hat Enterprise Linux 4. For this reason, HTML DB and Oracle Workflow are not currently supported on Red Hat Enterprise Linux 4.
Does this mean that workflow monitor cannot be used? Or workflow server itself cannot be used in Linux?
Is there any workaround for this problem? If I want to abort a process flow execution, is there a way to do it without using workflow monitor? In one of the other postings I saw a reference to abort method of workflow engine but this package does not seem to exist in the workflow server recent versions.
Thanks,

Hi,
The modpl/sql requirement will stop you being able to use the Workflow monitor, but the core functionality of the module will remain unaffected.
To abort a process, the WF_ENGINE package should have a procedure called AbortProcess - I haven't got a Linux installation to check on at the moment, but I;d be surprised if they have removed it, since this is used in a number of processes.
HTH,
Matt

Is Oracle Workflow required to execute OWB schedules?

Hi,
I want to create and deploy a schedule in OWB 10gR2 to automatically run my OWB process flow every week. I would like to know
1) Whether I need to install Oracle workflow too in order to execute the process flow as per the schedule created?
2) If not, how does the OWB scheduler work?
3) Also, if the scheduled proces flow terminates due to some error, how do I resume executing it from the point of termination after correcting the error?
Thanks
Amit

Hi Amit,
1. Is the workflow monitor a standard part of Oracle workflow,or does one need a separate license for it?All parts Oracle workflow (workflow server, workflow monitor, workflow builder) licensed with Oracle database licenses,
so if you buy Oracle database you can use workflow components without any limitations.
2. In your approach, you had mentioned that there should be no transitions for error, but I would like to send an email notification to the DW administrator incase of an error before suspending the process flow.My recomendation is to use additional PL/SQL procedure which will executed periodically (for example every 30 minutes, scheduled with DBMS_JOBS/DBMS_SCHEDULER),
in this procedure you can use query on OWB public view (ALL_RT_AUDIT_EXECUTIONS) or workflow repository views/tables
for identification failed steps/mappings (if you decide to use OWB public view) or "stucked" processflow (if you will use workflow views/tables,
algorithm of identification stucked processflow you can see in workflow PL/SQL package WF_ENGINE, procedure ProcessStuckProcess).
Using post-mapping is more expensive because you need modify each mapping which you want to monitor for fails.
Example of query for identifiaction failed steps (PL/SQL prcoedures and mappings) within period of time datetime1..datetime2 with ALL_RT_AUDIT_EXECUTIONS
select * from ALL_RT_AUDIT_EXECUTIONS where task_type in ('PLSQL','PLSQLProcedure')
and NOT (return_result is null or return_result='OK') and :datetime1<=created_on and created_on<:datetime2

How to access Workflow Monitor

Hello,
We have installed and configured Oracle Workflow Server 2.6.3 with the Workflow Configuration Assistant (in a 10g database schema).
Now we want to access the Workflow Monitor but can't find
a clear description of the configuration steps.
Can someone provide us with the steps needed to setup / configure the Workflow Monitor.
Thanks in advance.
Regards,
Dimitry Peelen

Hi Rich,
Can you please tell me where can I find the Middle Tier for OWF. We have installed Oracle Workflow as a stand alone product to support the Oracle Warehouse Builder.
I have installed the Oracle Work Flow Server 262 and configured the Browser. But whenever I try to view the process flow diagram a login window pops-up, after passing workflow schema user/password it complains about Monitor notinitiated.
Do I require Oracle9iAS to install the workflow middletier?
thanks

Workflow Monitor on Warehouse Builder 11g r2

Hi everyone,
I'm developing an ETL process using Warehouse Builder 11g r2 on Oracle Database 11g r2.
I don't find any information about installation and use of Workflow Monitor with this last release.
Before I used OWB e DB 10g r2 where I can find Workflow Monitor+Application Server+ Midtier in "Companion CD".
In 11g r2 there aren't a CD like that, and i don't now how to proceed.
The solution i thought is to use Workflow Monitor from 10g r2 companion cd but i hope in a better
and "updated" solution.
Can anyone suggest me?
Thank you!

Thank you so much for your answer, but my question is slightly different.
From .../owb/wf I've just installed Workflow 2.6.4.
What I need is Workflow Monitor, a tool where you can
see the execution of a process using a web browser.

Oracle Workflow 2.6 with Oracle 8.1.7 for linux

Is Oracle Workflow Server 2.6 available for Linux as a
standalone product against an Oracle 8.1.7 database?
Oracle Workflow does not seem to be included in the Integration
Server option with the 8.1.7 installation.
I've only found the Oracle Workflow Server included with the 9i
database. Will this work with 8.1.7 as well or does it require
9i db?
Thanks in advance for your help,
