Limitations on Using Human Task advance routing rules and stages

In one of our requirement we have used human task with different number of stages (14 stages ) and for all this we are using only one human task component and to route the task through different stages I am using advance routing rules (30 rules),we have exposed this through bpel .My code is working fine .
My question is:-
1- Do this kind of design contain flaws, is there is any restriction on using of number of stages and number of routing rules. Is there is any best practise which suggests that we cannot have more than certain number of stages or routing rules..??
2-Is it feasible to use different human task component for each of the human task stages and route the data using business rule, but that will be very exhausted and unnecessarily making bpel heavier, also the front end people will be having more number of bpm urls which will make their work tedious.
Please suggest .
Thank you

This doesn't sound good. That's an EJB internal to BPEL if I'm not mistaken. Did the install go ok? Has this ever worked before?
I'd check the logs on startup for any sign of an exception. This may be the symptom of a problem which will be logged on startup.
Also, search metalink and open an SR -- this EJB isn't something you need to configure in a normal install -- at least not that I'm familiar with.

Is it possible to update the human task payload without using worklist API but only using advance routing rule.

Hi,
I have one human tasks in BPEL process in which i am using different stages and with using advance routing rules i am routing my task payload to one stage to another.My payload has Task Status and Branch,after approving the human task from first stage I want to send modified value of the Task Status to the next stage without using worklist API or manual updation but only using the advance routing rules,is it possible ??? If anyone have any idea about this than please enlight me with your valuable solutions and advices...
Thanx

Hi SamGoe,
According to your description, my understanding is that you want to update the PoerPoint slide from SharePoint 2010 slide library automatically.
It seems to be not necessary to use Macros. SharePoint provides an OOB way to notify you to check for update to the slide library slides when you open the presentation. PowerPoint does this because you selected the option
Tell me when this slide changes when you copied the slides from the library.
More information, please refer to the link below:
http://office.microsoft.com/en-us/powerpoint-help/sharepoint-slide-libraries-ii-use-slides-in-the-library-RZ010254089.aspx?section=6
I hope this helps.

Using Human tasks in a BPM process

Hi
I managed to deploy the VacationRequest sample which uses human task in a BPEL process.
I want to implement the same human task in a BPM process. Are there any tutorials or stepswise guide for the Vacation Request sample using BPM process?
Also, what are the main differences between a BPEL and a BPM process because most of the things that are done in BPEL can be done in an BPM process as well.
Thanks

I was able to implement the same using a BPM Process.
For those of you, who may require the steps:
1. Create a webservice based on the VacationRequest.xsd with VacationRequest as request and VacationResponse as CallBack
2. Create a human task and task flow as described in the VacationRequest.pdf provided along with the sample.
3. Create a BPMN process, associate the Start Event to the WebService Interface and map the request and response.
Also associate the End Event to theWebService callback port.
4. Deploy the process and taskflow.
But I have a query here? Even in the sample given(using bpel process) how will the requestor know that the leave has been approved/rejected.
what exactly is sent out as the response to the call back port. And, where can the requestor view the response?
Regards

This is a problem with switch inside a switch.
When I replaced the switch in the human task with other activities, it works fine.
It throws a problem just having a process starting with a switch and a workflow within one part of the switch

Human Task Auto Release Default and configuration question in 11g

Is there anyway to turn off the auto release feature of a human task if you do not put an expiration date on a task? Also the documentation says the default is 12 hours. If there is not a way to turn off the auto release feature, can the 12 hour default be changed? The documentation is not fully clear to me and then when I look at the UI from the console I do not understand what the identifiers of P5D, P4D, etc mean under the Default Duration column. I get the use of percentage but it is unclear what Default Duration is and how to use that field.
I saw in 10.1.2 there was a way to turn off the auto release feature of task via restrictedActions but I did not see this in 11g.
And last question is does anyone know if human task is stored to a database if it runs for too long similar to the concept discussed around bpel processes of hydration and dehydration?
Thanks,
Diane

I am able to fix this issue. After a series of R & D I was able to find that the root cause is %APPDATA%\jdeveloper. Deleting the relevant directory will solve this issue. In fact, I tried to delete the entire jdeveloper directory under %APPDATA% and the jdev 11.1.1.7 form generation issue got resolved. Those who find "referential integrity" issue may follow this approach.
This solution also applies to this thread

Parallel or sequential routing rule and recovery

I'm trying to implement fault handling via fault policies for a composite, to get faults into the error hospital so recovery is possible.
The fault I'm trying to catch is a service call from a mediator component, but for that to work I have to change the routing rule from sequential to parallel.
So far no problem, it's working.
There are a few synchronous services I want to be able to recover as well, but this is not supported:
"parallel routing rules are not supported for Oracle Mediators with synchronous operations".
Is there another way to get instances of synchronous services into the error hospital for recovery?

Report router rules and drop off library in Sharepoint

Hi,
I am running the report from the Report Setting link in Duet Enterprise. I get the message saying, 'The report has been submitted for processing and will be delivered to your Reports page".
But i am not getting any reports in the reports page. After googling, i got to know that i will have to confiure the Report Routing rules for the same. Also a Drop off library needs to be maintained.
Could anyone please explain the detailed steps for doing both these activities? Being a SAP expert, i dont know much about SharePoint sites.
~ Ramanath

Hi,
lets perform some checks to see where we are actually failing.
The error
User may not be a Duet user.
SAP system not configured or changed on add-on.
SAPID passed was not present in the master system.
means that somewhere on the server where the report is running the information that is retrieved from the SCL server is not correct. In your case these two systems (the server that is running the report and the SCL) are the same, but technically the flow is similar to the case that both would be on seperate system.
So the first thing I would check is if the RFC destination and the logical port that was configured is correct.
(all the following steps are done on the SCL in your case):
At first go to LPCONFIG and search for the Proxy Class: /OSP/CO_REP_ADAPTER_WSVI_DOCUM with Default Port checked.
Make sure that this logical port is active, then go to the Call Parameters tab. Here you should see in the HTTP Destination an entry IWCNT_REPT_ACT_HTTP_DEST.
Double click on that (don't save any changes if you get a prompt) and you will end up in SM59. Here you should see in the target host field the hostname of the SCL server. Under Service No. the HTTPS Port of your SCL system and finally in Path Prefix you should see something like this:
/sap/bc/srt/pm/iwcnt/repadapterwsvi_document/001/duet_enterprise_assertion/1/binding_t_https_a_http__-iwcnt_-repadapterwsvi_document_duet_enterprise_assertion
Before performing a connection test, go to the "Logon & Security" tab. Here you should see in the "Logon with Ticket" secion "Send Assertion Ticket for Dedicated Target System" checked and also SSL Active in the Status of Secure Protocol. The SSL Certificate is set to "ANONYM SSL Client (Anonymous)".
If that is all the case, then click on "Connection Test". The result should be a HTTP 415.
Let me know if that helps.

Holger.

Using dataexport in a business rules and define the filename with a sub var

Hi,
I have created a calc script to export data using DATAEXPORT, and to define the filename an essbase variable.
Here all right
I copy this code to a business rules to run it from a business rules, but I have a problem with the essbase variable, when I validate it, it gives me the error:
Detail:Encountered "&FileNm" at line 28, column 26.
Was expecting:
My essbase variable is set to:
"e:\Hyperion\products\Essbase\EssbaseServer\app\TMPGB\dataexportCustomerY2.txt"
in double quote
How anyone use in a Business rules with the command dataexport an essbase substitution variable

Just tried:
Script: DATAEXPORT "File" " " &Filename "#Missing";
SubsVar: "c:\DataExtract.txt"
it worked with no issues.

Human Task – Using expressions in task parameters

Hi All,
In my BPEL process I have a Human Task with about 15 task parameters. I'm trying to define BPEL variables to each and every parameter. I am able to select a type 'variable' variable (ie. /ns18:OutputParameters/ns18:street_name) from tree view and save.
However, whenever I click on the little flash-light icon and create a type 'expression' using the XPath expression builder I'm having problems saving the change.
In details this is what happens,
0.) Double click on Human Task
1.) Click on flash-light icon in front of a parameter.
2.) Select Type expression variable.
3.) Click XPath expression builder.
4.) Select conversion function 'string()' and double click to add.
5.) Double click on the required BPEL variable to add.
6.) Something similar to the following expression is created,
string(bpws:getVariableData('InvokeGetAllABCInformation_FetchABCInformationService_OutputVariable','OutputParameters','/ns18:OutputParameters/ns18:ACC_ID'))
7.) Click OK twice and then Apply/OK to go back to BPEL diagram view.
8.) Now at this point the BPEL is not saved and the tab-title is italic to show it’s unsaved.
9.) Save the BPEL to disk.
10.) Double click on the Human Task to show parameters and variables defined.
11.) The previously defined expression type variable is still there.
12.) However now if I click either 'Apply' of 'OK' buttons without making any changes the BPEL diagram tab-title becomes italic and when the BPEL is saved to the disk, it forgets about all the expression type variables that was previously defined. Also note that cancelling wouldn't change anything.
This is a serious issue as I can't change any setting to a Human Task parameter list, as every time I make a change, I loose all the expression type variable declarations.
Could this be a bug in JDeveloper?
My JDeveloper Studio Edition Version is: 10.1.3.3.0.4157
Any help on this would be greatly appreciated.
Thanks.
Shaminda.

ok, looks like no one knows what's going on,
Here's the workaround that I came up with, If anyone is interested.
Create a custom XSD (schema) with required variables in it (to be used by expression types vars), and use a copy operation before the human task and create the expression types in there. Then use the schema to map the values to the human task.

Its due to JDeveloper installation or cache issue...
I uninstalled completely and installed again. I am able to create Human Task now. Maybe it helps someone.

Designing Sequence of Human Task

Hii All,
I want to design a BPEL work flow for for LOAN approval process where user submits application and if system checks for all required fields if found correct then
it goes as a task to user RM and if approves it it goes for another user AM for approval otherwise it rejects with reason stated.here two human task are involved can anyone please help me and tell the steps i should follow to design this.whether i have to make nested human task or any other process is there in human task.
thanks and regards,
Deekay

Another option is that while designing human task you can have two stages instead of one.
- Open Human Task from Composite.xml
- Expand 'Assignment and Routing Policy'
- Select 'Stage1.Participant1' that is the first stage activity
- Click on th '+' icon under Assignment and Routing
- Select Sequential Participant Block. In the popup select your second participnat/block.
- Go to advanced section of this popup, and check 'skip', Specify a skip rule for this stage. You can choose the outcome from first stage and match it with 'Reject' to skip this stage
HTH

Error authentication user in WCS about Human Tasks

Hi All,
We developed a BPM workflow and 4 human task(HT) in ADF and using WCS for accessing the tasks of the human workflow.
We are working using the virtual machine soabpm-vm 11.1.1.6 ps5, downloaded by the Oracle Web Site.
I created a space in WCS, based on the BPM-Workspace templace present in the WCS.
I was able to execute the process and the HT without any problem.
I am adding security to all the 4 HT following the indication about ADF security, using the ADF wizard in jdeveloper.(see Oracle WebCenter 11g Handbook chapter 18, page 421)
After implementing the following choices:
1)ADF Authentication and Authorization
2)HTTP Client Authentication
3)No Automatict Grants
4)Either for WebPAge, Either for taskflow i have enabled the view privileges for viewing the page or executing the task flow.
5) I linked the valid-users with a groups in my realm(AdmiServer)
I tested all the security implemented with BPM worspace application (https://hostname:7002/bpm/workspace) and it is working correctly.
If i test it within webCenterSpace the HT are not working. When i click on the HT i got the following error:
Error 401 Unauthorized
The request requires user authentication. The response MUST include a WWW-Authenticate header field (section 14.46) containing a challenge applicable to the requested resource. The client MAY repeat the request with a suitable Authorization header field (section 14.8). If the request already included Authorization credentials, then the 401 response indicates that authorization has been refused for those credentials. If the 401 response contains the same challenge as the prior response, and the user agent has already attempted authentication at least once, then the user SHOULD be presented the entity that was given in the response, since that entity MAY include relevant diagnostic information. HTTP access authentication is explained in section 11.
This is what is happening:
I logged in into WebCenterSpace with the user credentials (Username pwd). I am correctly authorized and identified.
I later click on the HT and the user is not propagate as the logs say that anonymous user try to access to the HT.
Why there is this different behavior between WCS and BPM worspace application?
Can i have same indication about what to do in order to get the HT working in the WCS?

Hi Praveen,
To fix this issue, you need to change the Identity of your website's Application Pool to use the
NetworkService account (or the less secure LocalSystem account). By default, IIS7 seems to set the Application Pools Identity to 'ApplicationPoolIdentity' instead of NetworkService or LocalSystem.
Here's a step-by-step guide for determining your websites Application Pool, then changing its Process Model Idenitty in IIS7:
1.Open Internet Information Services (IIS) Manger.
2.In the Connections sidebar, drill down into Default Web Site and click on your website.
3.Now in the Actions sidebar (on right side), click on Advance Settings... In the popup box, under General you will see your Application Pool listed for your website (in my case the app pool is: ASP.NET V4.0).
4.Click Cancel... If you choose, you can change the Application Pool here, but for the sake of this example we just wanted to find out what the website's App Pool was.
Then change the app pool's (Process Model) Identity to 'NetworkService', the steps are showed as below:
1.Open Internet Information Services (IIS) Manger.
2.In the Connections sidebar, click on Application Pools.
3.Now right-click on theApplication Pool that your website is using (in this case my site is using the ASP.NET v4.0 application pool), and select Advanced Settings... from the menu.
4.In the Advanced Settings pop-up box, locate the Process Model -> Identity section and click on the Application Pool Identity.
5.In the Application Pool Identity pop-up box, change the Built-in account to NetworkService (or if you want LocalSystem), then click OK, and click OK again to save your Advanced Settings changes.
Hope this helps.
Best Regards,
Peja

Problem in BPEL Human task

I am developing the BPEL process in jdeveloper11g. I used Human task for serial approvers.
When I test the service I was able to see the Recive and Callback of human task.
I want to Invoke partner link (used for DB adapter) whenever first approval approves the task . So that I can update the status of current approval as approved ( second approval status should be Pending), after approving from second approver only the second approver status should be updated as approved.
but the procedure of updating status i.e.. Invoking partner link is executed after approved by all approvals.
Please let me what I am missing.
Thanks in advance.
Sandeep.

I am using Invoke activity to retrive data from data adapter . After that I am using While activity to iterate from the retrived data. And in While activity I placed Assign activity along with Invoke Activity to update retrived data.
but here insted of iterating from each record it goes infinite loop.
I have given "true () " as expression for While activity.
please let me where I am missing. Please its very urgent.
Thank you.
