ConcurrentModificationException while applying filters in BPM workspace

Hi,
We have a Oracle BPM 10g 10.3.3. for weblogic environment. Getting this below error whenever I apply filters in workspace. The work items does not get refreshed either. However when I do a refresh in the browser('F5') the filters are getting applied and the work items are coming up filtere? Is there any way to get rid of this error? Is this a bug in the weblogic server?

Unable to open BPM Workspace after applying 11,1.1.5 patch BPM PS4 FP

After I login to BPM Workspace(http://<host>:<port>/bpm/workspace) , I get a blank page.
The logs show the following error -

We applied a patch to the 11.1.1.5 SOA installation to prevent an issue from occuring . After that we are getting this issue.
Interesting thing is that the URL - http://<host>:<port>/integration/worklistapp/ works fine.
Can someone please suggest what might be wrong ?

Error in writing to file encountered while applying patch 9.2.0.8

Hi,
I encountered the error message below while applying Oracle 9.2.0.8 patch set using OUI on server running Oracle 9.2.0.7 and Windows 2003 Enterprise Edition SP2:
Error in writing to file 'C:\oracle\ora92\BIN\orapls9.dll'
[C:\oracle\ora92\BIN\orapls9.dll (he process cannot access
the file because it is being used by another process)]
I've already stopped the Oracle instance and services before invoking the setup.exe.
My question is: Why this is happening and what is the resolution to prevent this error from happening?

I used the script in the Metalink note 454040.1 and chose 5. I typed in the orapls9.dll to see which module is locking this dll and I found out it is avrrepsvc.exe which is one of the services our application is running. I just stopped it in Services Console and run the setup.exe of the patch. The installaton of patch run successfully. I checked the version using 'select banner from v$version' and I now got this results:
SQL> select banner from v$version;

New task record not getting created in BPM workspace.

Hi,
We have a BPM Process which has 2 roles. SKURequester and SKUChangeAnalyst.
When we initiate the flow , it opens up a screen and we populate data and click "SUBMIT".
It goes to ChangeAnalyst for approval.
It is working fine in Development Env.We could see a new task created for ChangeAnalyst once the requester SUBMIT's his task.
But in Test env, Once the requester submit's his task .It's not creating a task row for ChangeAnalyst in BPM workspace.
We verified the roles assigned to the user.Everything is same.
Repeatedly seeing the following error in LOGS.
Please help.

BPM Workspace 11.1.1.4 fails after login

Hi,
I am getting an issue when logging into BPM Workspace (11.1.1.4) where the browser displays nothing and the SOA Server log shows the following issue compiling bpmHome.jsf.
]] Root cause of ServletException.
weblogic.servlet.jsp.CompilationException: Failed to compile JSP /bpmHome.jsff
Exception occurred while processing '/SOA/Oracle/MW_11.1.1.4/user_projects/domains/soa_domain1/servers/soa_server1/tmp/_WL_user/OracleBPMWorkspace/jx2oeu/war/bpmHome.jsff'java.lang.NullPointerException

(I also get a diagnostic image generated).
I have rebuilt the Domain from scratch - same behaviour.
The other BPM web-based apps (composer and Worklist) seem fine.
This is running on Ubuntu.
Can anyone help?
Thanks,

Hi,
I managed to fix this on my own as I started looking at the BPEL side of things and started getting errors deploying services to the SOA Server due to too many files being open.
To fix this I bumped up my open files max from 1024 to 4096.
I also added some extra Java properties to my setDomainEnv.sh to get rid of the following start up message...
<BEA-000402> <There are: 5 active sockets, but the maximum
number of socket reader threads allowed by the configuration is: 4. You
may want to alter your configuration.>
EXTRA_JAVA_PROPERTIES="${EXTRA_JAVA_PROPERTIES} -Dweblogic.ThreadPoolPercentSocketReaders=50 -Dweblogic.ThreadPoolSize=100 -Dweblogic.SelfTuningThreadPoolSizeMin=100"
export EXTRA_JAVA_PROPERTIES
This definitely improved performance drastically but I don't know which of the above steps fixed my BPM Workspaces problem (maybe its both) but they both helped me with each problem I had.
Cheers.

Process is not visible in BPM Workspace in Application panel 2

Hi dear developers,
I had a problem about BPM process. I was trying to implement this tutorial -> http://st-curriculum.oracle.com/obe/fmw/obpm/11g/r1/firstProcess/firstprocess_obpm11g.htm#t3
And all the steps had been done. But the deployment step, i couldn't see my process on the BPM Workspace. I searched the other opinions in the forum. It's completely same with this thread -> Process is not visible in BPM Workspace in Application panel
Nevertheless, couldn't find anything helpful. Could you help me please?
Thanks in advance.

Hi Erdo
I hope you already ran the demo community seed app to create all the test users and groups etc in the default authenticator. If not, please see this below post:
Re: New to BPM: How to get the tasks in the Workspace
1. First login into bpm/workspace with domain adminstrator username/password. Then on right side, click on Adminstration link and see if you could see all the roles related to hello world app and also the users that you added to those roles.
One other very basic thing is, you should and must deploy the TaskForms project that has all the taskdetails UI pages. I hope you did this while deploying the workflow and checking the check boxes to deploy other ui projects also.
If seeding and getting demo uses is confusing, you can always use your own users. From weblogic console, create some extra users like weblogic1, weblogic2, weblogic3 etc with some password. Then use these users to assign to the roles from hello world app. Then login with these users. This will also work.
Thanks

BPM Workspace User view related issue

PROBLEM SUMMARY_
Unable to see filtering options like SEARCH, ASSIGNEE and STATE in User View, I am able to see this in Generic Inbox of BPM workspace
DETAILED DESCRIPTION_
I am new to BPM & need some assistance on below scenario-
TASKS INVOLVED-*
My BPM process contains 2 tasks
1.     Initiator task-[Part of Requester role in my JDev Swim lane]
2.     User Task-To review the request-[Part of Reviewer role in my JDev Swim lane]
SCENARIO-+
Flow would be something like, requester enters details in request message & says submit. If request message length is less than 6 characters a review would be required & therefore process flow would go to reviewer task. Reviewer can Approve or Reject the request, if he approves the process will write the request message contents to a file, if the reviewer Rejects the request, requester task would be created again so as to ask requester to enter a message of length>6.
If entered request message is having length greater than 6, no review would be required. It will be a direct file write.
CHALLENGE-+
The challenge is each of these tasks –Initiator task & Review task would be created with DIFFERENT task numbers in BPM workspace, which I do NOT want. I want the Requester tasks task number to be propagated to Reviewer task and I would want to populate this as task number (May be under different column, say Request Id) of Reviewer task as well.
After reading Oracle BPM docs, I studied that this can achieved using Human tasks-Mapped variable concept.
I used protected mapped variable/flex variable:*Request Id* in both the above tasks to achieve this.
PROBLEM-*
Problem is in BPM workspace’s user view, here we go-
I created a user view:*HelloWorld* to display the task details, the columns I want are the default columns+Column for mapped attribute:*Request Id*.
Now even though the Request Id column is populated as expected, I cannot filter the View entries based on Assignee, State or perform any kind of other searches.
I understand that User views are built based basically on certain filters itself. But post the view creation if user has to make a search-say based on Mapped attribute:*Request Id* in this case, he won’t be able to do so.
This defeats the entire purpose of Mapped attributes. Oracle document says (check the last bullet point)-
+"Human workflow mapped attributes (formerly referred to as flex fields) store and query use case-specific custom attributes. These custom attributes typically come from the task payload values. Storing custom attributes in mapped attributes provides the following benefits:+
+•     They can be displayed as a column in the task listing+
+•     They can filter tasks in custom views and advanced searches+
*+•     They can be used for a keyword-based search"+*
So is this a bug with user views in workspace?
One more thing that I would like to add-Reason behind using Custom user views is-
1)     Generic Inbox of BPM Workspace does not give option to make the mapped attribute get displayed/Searched
2)     I want to customize the Tasklist.

Oh well...
It seems there's a bug with the XE Database... Sometimes it freezes some components and the SOA Plataform goes crazy.
Simple system reboot solved.

When Searched in Oracle Support Here is the information that they specified. But This is also not working.
Service error.
Internal Error; Service error occurs in IdentityService in method lookupUser.
Refer to the log file that is configured for oracle.soa.services.identity for more details on this error and contact Oracle Support Services
at oracle.bpel.services.identity.client.AbstractIdentityServiceClient.lookupUser(AbstractIdentityServiceClient.java:195)Cannot log in to workspace( BPM 11g).
Fix
One of the reasons this issue might happen is when the application (in this case the Workspace) was not able to connect to the Identity services.
And the cause of bug was network configuration issues which prevented connection to IdentityService SOAP endpoint using the configured server hostname.
So to overcome this issue, set the ServerURL property in the soa-infra config mBean to http://127.0.0.1
This should resolve the issue.
An alternative option is to use any other valid server IP address / port.
In future the bug fix will have log messages which will post warnings in the logs if the host name used in the URL is not resolved.
How to set the MBean:
1. Login to the em console
2. Right click on soa-infra
3. Goto Administration ->SystemMBean Browser
4. Goto Application Defined MBeans
5. Find Oracle.as.soainfra.config ->Expand "Server: <your server name>"
6. Goto SoaInfraConfig -> click on soa-infra
7. Find the Property ServerURL, enter value as http://127.0.0.1
8. Click on Apply

Edited by: rajMS on Jan 24, 2013 4:18 PM

This is related to the authentication providers you have configured in WebLogic. Check that the providers are configured property for whatever identity store you need to use - integrated WebLogic, OID, AD, etc. - and that they are in the correct order.

How to expose a Delegate feature of BPM workspace to oracle primavera

Hi All,
We have Oracle primavera which is getting used for Project portfolio management and we are using BPM workflows to manage it. All the Human task pages are designed on ADF which can be accessed directly from Oracle Primavera application by users.
Now we want to implement a delegate feature of oracle BPM but as per my understanding that feature we can use through Oracle BPM workspace>> task actions list. But as all the tasks and UI's user is accessing using Primavera application hence is there any way that this delegate feature of oracle BPM workspace can be exposed to primavera application so that user can use this feature of BPM workspace in oracle primavera?
Please help me whether this thing is possible or not and if yes then how to go about it.
Thanks

BPM workspace error.

Hi All,
I am getting the following error while logging in. When I enter my username and password in the BPM workspace browser it shows me the home page for a fraction of a second and then shows this error.
Error 404--Not Found
From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:
10.4.5 404 Not Found
The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent.
If the server does not wish to make this information available to the client, the status code 403 (Forbidden) can be used instead. The 410 (Gone) status code SHOULD be used if the server knows, through some internally configurable mechanism, that an old resource is permanently unavailable and has no forwarding address.
I think this error is comming as I deleted some role in the workspace by going to the admin page. Could anyone please suggest how can I solve this issue.

Guessing you've done this, but look at the log files for the domain when you get a chance.
If this does not help and it is not a production environment, you might want to consider undeploying the composite project that had the roles that you deleted.

Error during addition of external link to oracle BPM workspace

Hi All,
I just want to add an external link to oracle BPM workspace and I've followed this tutorial :
http://docs.oracle.com/cd/E28280_01/user.1111/e15175/bpmug_ext_apps.htm
but I am neither able to view the required, nor getting any error.
During deployment time I'm only getting this message :
Issues were encountered while parsing this deployment to determine module type. Assuming this is a library deployment.
I'm using the virtual m/c version : oel5u5-64bit-soabpm-11gr1-ps4-fp-Workshop-Exp_2
Please help me to resolve the issue.
Thanks in advance.

What I meant to say is check the logs at the time you are getting the error since sometimes the logs can be huge in size

Can we able to see the Work Items status in the BPM Workspace

HI,
Can we able to see the work item status in the BPM workspace.
For exampls, I have create the request as requester then it will go for approval.
After sometime i login into the workspace can i able to see my request status(it mean where it is like approval1, approval 2)?
Pls let me know, its possible in the BPM workspace.
Regards,
Anandh P

Hello Anandh,
You can utilse the filter option of the BPM workspace.
When you filter the instances you can view the status of all the instances even if they are currently not assigned to the particular user.
All you need to do is click on the show filter link.
Select the process from the Filter by: combo box.
Check the status boxes and click on apply filter.
You will be able to view the instance even if it is not assigned to you.(Though you will not be able to work on it.)
If you wish to give custom messages like "pending with HR" or "Pending with Admin" then you need to add a column by creating a project variable and mapping it to the custom view. Then these messages can also be shown on the instances.
Hope ths helps.
Regards,
Jaydev Doshi

SSO on bpm workspace console

Helllo,
i need to protect the bpm workspace administration console with OAM 11g. I can't find how this resource can be created on OAM.
This is the url to protect:

Do you know how i can define this resource in OAM?
Thank you,
