Several Process With Initiator Task, same composite

Hi,
We're trying to create several processes, all of them started by human tasks, Initiators, but all of them are on the same composite.
When we deploy this application to the server, We only see ONE process in the tasks list. Does anyone have any idea what's needed to get them to be shown, all of them, so we can use any of the processes?
We're using Oracle BPM 11g (11.1.1.5FP)
Thanks in advance
Pablo

Hi All,
The problem was caused by the JDev version I used.
I used the version 10.1.3.4., but found a thread which suggested that I should use 10.1.3.3. instead. And it works!
Here is the thread where I found this info:

Several process listening to the same port number

I hope I am in the right form (it's the third one I am trying).
I have server/client application, one server that handles a lot of clients. In general when ever a client approach the server, the server create new process (fork()) that handle the client request.
I would like to know if there is a problem that several processes (parent and several child processes) are listening to the same port number, is it better to create thread that would handle the client request, instead of creating a child process?
To better understand the problem I create very simple client and server application.
This is a part of the server application:
The server creates a socket, bind to this socket and then listen to this socket.
After that in a while (1) loop he waits for accept:
int sockclient = accept(sockId,(struct sockaddr*)(&client_addr), &addrLen);
When the server get a sockclient (client ask for service) he create new process (fork()) that handle the client request.
struct sockaddr_in addr, client_addr;
bzero(&addr,sizeof(struct sockaddr_in));
addr.sin_family = PF_INET;
addr.sin_port = 8865;
bcopy(ent->h_addr_list[0],&(addr.sin_addr), ent->h_length);
// bind
bind(sockId,(struct sockaddr*)(&addr), sizeof( struct sockaddr_in));
If it would help I can add the all code.
If you knows about articles that talked about this subject It might help too (I am talking about advantages and disadvantages of thread against process but regardless of sockets).

You might look at this article
http://httpd.apache.org/docs-2.1/misc/perf-tuning.html
under the section "accept Serialization - multiple sockets".

Process with Human Task (Deployment problem)

Hi Every1,
I'm a rookie BPEL developer who ran into a problem. I'm using a separate machine as SOA server, because I couldn't install it on my dev machine for some unknown reason. In the beginning, after setting up the necessary connection settings in Jdev everything worked fine. But when I use a Human task in my process flow and auto generate a task form for it then I can't deploy my process to the server anymore. I've found this problem in other topics, but none of the solutions worked in my case. There are mainly two reasons mentioned: 1. RMI settings - Tried to set it in build.properties, but nothing changed. 2. JDK version differs on dev machine and server - In my case, both the dev machine and the server has exactly the same version (1.5.0_06). Is there any other ideas what could be wrong?
Thanks,
Peter Neumann

A web site I used to visit daily, but haven't for a while, causes Firefox to go off in la-la land. I have to kill the process with the task manager.

The web site in question is for our local newspaper. The problem occurs when I am returning from a discussion thread (by Disqus) to the article it's attached to. Also when I attempt to return to the home page from an article. Sometimes just letting it sit for a while will produce the problem. At that point I cannot open a new tab, switch to another open tab, close tabs, click on any menu bar items or close the app. The tab I was in shows the spinning wheel and says connecting. I must use Task Manager to kill the process. I tried installing version 31.0 with no result.

Can I build an user Interface using a proccess with Human Task?

Hi,
I'm building an application, web application, with a several screens. The application just will be used for entering some data and depending on the data entered, some bpel process will be launched.
I'm thinking about implementing a MVC using a BPEL Process with Human Task. I mean: I'll make everything with bpel process (*including the application*). I would make a bpel process with some human task. This process would be like a Spring Webflow file or similar. Each screen wouldl be a human task but with synchronus nature. Will it be possible? Will it be so complicated? Is it usual?
Other way would be making a web application to enter data and then launch a proccess that will record the information in the database. That would be the normal way.
Thank you so much.

Hello,
There's a more powerfull solution you may use.
You can create a View. Some Views can be updatable (it means that it's possible to update
the Table from the View) and, you can add constraints (Primay Key) on a View.
For instance:
CREATE OR REPLACE VIEW {color:red}User2.view_name{color}
({color:red}col1{color}, {color:red}col2{color}
UNIQUE RELY DISABLE NOVALIDATE,
CONSTRAINT {color:red}pk_view{color}
PRIMARY KEY {color:red}col1{color}) RELY DISABLE NOVALIDATE
) AS
SELECT {color:red}col1{color},{color:red}col2{color} FROM {color:red}User1.Table1{color};This example is from the link bellow:
[http://www.psoug.org/reference/views.html]
Hope it can help.
Best regards,
Jean-Valentin

Problem with user task

Hello all,
we're working with Oracle BPEL Process Manager 10.1.2 (JBoss 3.2.6) on Windows XP (jdk 1.4.2_03).
I've successfully run many examples provided with this distribution (e.g LoanFlowPlus demo).
However when we try to build a BPEL process with user tasks defined, we are able to launch task, but when we complete such tasks nothing happens, and onTaskResult method is never called.
This is the code we use to complete a task (Task are completed from web pages):
String _taskId = request.getParameter("TaskId");
IWorklistService worklist = (IWorklistService) locator.lookupService(IWorklistService.SERVICENAME);
ITask task = worklist.lookupTask(_taskId);
// getResponse returns a String
_task.setConclusion(getResponse());
// getAttachment returns a XML Document
_task.setAttachment(getAttachment());
worklist.completeTask(task);
After these sentences are performed such task is not returned when _worklist.listTasksByAssignee("[email protected]") is performed, but onTaskResult is never called. No error messages are shown.
Any idea?
Thanks.
Javi

I've found a possible cause for this weird problem.
It only happens when completeTask is called and somebody has the flow view page on the BPEL Console open.
If nobody is browsing through the BPELConsole web environment task are completed successfully...
¿?

Process and Human task deployment version difference.

Hi,
I have a small issue in deploying the process and taskform. Problem is my BPEL Process deploys fine and shows the version 1.0 my TaskForm also deploys fine but somehow the version of this shows as 2.0. When I check the App Server the TaskForm shows as 2.0. Now when I log into worklist and go to task details I see an error saying /1.0/TaskForm.jsp not found. It's because the TaskForm is deployed as /2.0/TaskForm. Now if I manually go and change the context of the task form in default.xml file to 1.0 worklist shows the jsp form. Before deploying the Process I tried deleting the output directory, undeployed the form for the server, undeployed the BPEL Process and restarted everything but some how the form is always deployed as 2.0.
When I manully force the BPEL Process to deploy as 2.0 also all works fine.
Can someone please tell me what might be the issue. I believe it's something JDev. do when deploying the process that somehow incremenst the TaskForm version.
I even installed a fresh JDev. version but nothing works. Is something cached in the process and if so where to look and fix it.
If I create any new process with Human task it works fine. It's something with my current process that's not right.
Thanks

Hi All,

I tried to install yosemite yesterday and my computer goes through the whole installation process and then to a blank white screen. I've rebooted, I've reinstalled several times and get the same result. Two days wasted and I can't use my computer!!

I don't know if you've already resolved your problem, but I had the same thing, it took me 6 hours to fix it. I had the exact same as you, installed the update and then it went to a white screen. After trying start up holding down cmmd r or holding down the alt key to try to install it again, nothing worked, same result every time. Then an angel came to me here somewhere but I can't find it now to thank him. Start in safe mode, press shift once you hear the start up chime and hold it down until you hear it again. Installation completion box came up and it was working. turn off computer and start up again normally and all is well. Except my final cut pro x doesn't work with it, have to update that now too. same as when I updated to mavericks.
Hope this helps.

Why can´t i have more than one initiator task on my bpm process

Hi All.
I am working with BPM 11g and would like to know:
Why can´t i have more than one initiator task on my bpm process
In this case, i will have two separeted process where each has its initiator task?
Regards,
Diovani

Hi Diovani
Two different processes can have different task initiators...task initiator means creation of a process instance which can happen only once

Two transactions, same program, processed in background task problem

Y0 Team ABAP,
i got something here that bugs me.
I have done a report. Nothing special, simple selection screen, selection of data, and output via SALV.
One of my selection screen fields (a parameter) is VKBUR and it is "obligatory".
2 weeks ago i got the requirement to create a copy of this program, and adopt VKBUR as select option.
Since i didnt want changeanomalies i decided not to duplicate the program, but just add a second transaction to my program.
In a routine at event at-selection-screen output, i´m hiding either the parameter or the select option, depending on which tcode was used.
In some routine which gets triggered at the event at-selection-screen i´m moving either what we got in our parameter to our local range we use for the select, or just assign the select option to our local range, or process an error message if according field is not filled. Yeah that obligatory condition is done by myself since i cant just set the obligatory addition to the statement.
This all works quite fine so far.
BUT:
Today i hear that the end-users process that report in background task by pressing F9.
Problem is now that when it is processed in background task, sy-tcode is initial, so i dont know which of the transactions the user picked, and so i dont know which of the two fields has to be filled.
Sure i could do another report, containing just my second selection screen, and when this is checked, do a submit on my real report, tho i still believe there must be some more elegant way.
Any ideas?

Unfortunateley those subtotals cant be handeled by the layout, thats why i manually add them.
But you got me back on track! right now i´m for your solution.
right now i´m having just ONE selection screen with the select option on it.
User can decide if he fills just one value or more.
In the end i loop over my output table and look if there are records of different VKBUR´s.
If there are i know he wants subtotals and process them. If its just data of one VKBUR i can spare myself the hassle as there is anyway just one records per VKBUR so subtotaling this wouldnt make sense.
thanks. Thats what i will present my consultant now lets see if i can get him satisfied with it...

Initiating bpm 11g process with an attachment?

Hi,
Facing problem in passing the attached file to the next human task.
Basically, initiating a bpm process with file adapter getting the file as an attachment. after that need to pass the file to next human task for approval.
stucked in passing the document to next human task.
is there any way i can do it??
Please suggest something.
thanks in advance

User/Role management is now done through the workspace itself. You must login as an administrative user (like weblogic) and you will see an Admin link in the upper right of the workspace.
Authentication and user lookup is now handled directly by Weblogic - so you setup authentication Providers in the WLS security realm through the admin console.
By default Weblogic is configured to use an internal LDAP that stores local users (this is where the "weblogic" user itself is defined).

Problem loop processing with a foreground task

Another problem: I have taken the example task provided by SAP to create a sales order in the foregrouund by passing it data from an ORDERS IDoc (the task is TS20000615). This task calls transaction VA01 with the data from the IDoc converted into a BDC table, and then displays what is happening as a foreground process.
I wanted to have this in a LOOP until a sales order nuumber was created; my thinking was if somebody starts the task and is unable to save the order at that time, the existance of the order number would be the LOOP condition, and a new work item would appear in the recipients inbox.
When I tried this, I end up in a constant screen processing loop, never seeming to exit the task, i.e. it looks as if when I cancel the processing for one task, it automatically starts the next and displays the screen processing.
Is there an obvious mistake here, or am I doing something that is fundamentally flawed?

Anthony,
What you need is task based on an asynchronous method with a terminating event. This will keep the same WI active until it is succesfully completed instead of generating a new WI for each execution.
Change the property of your BDC method to Asynchronous.
Define a terminating event for your task (inputFinished?).

TB hangs and I cant kill it with process explorer or task manager. Have to reboot. Problem is intermittent.

TBird V31.2.0: Windows 7 home premium with service pack 1: hp pavilion dv7 laptop.
Intermittently, TB hangs and I can't kill it with normal close, or process explorer, or task manager. I have to reboot to get a clean copy of TBird to view my mail.
Problem is chronic (about a 2 to 4 months). I updated TB several weeks ago but no joy.
The green bar (lower right) that indicates download progress is at max extent and stays their when the problem exists.
Error msg. appearing with attempt to kill TB says roughly - the instance of TB in not functioning. Kill it or reboot. Its a real pain to reboot. If someone could give me a clue to at least kill the hung instance of TB that would be a great help. I've been using TB for years on at least two computers and never ran into this before.
Thanking you in advance for any help offered.
Frank

Which operating system are you using?
Resetting the photoshop preferences might cure the problem.
Press and hold down the Shift+Ctrl+Alt keys down just after starting the launch of photoshop 7
(Shift-Command-Option on a mac)
Keep holding the keys down until you get a dialog asking if you want to delete the adobe photoshop settings file
Press Yes

Image processing with imaq vision with 2 webcams on the same computer

Hi,
I'm currently trying to set up 2 usb webcams (logitech quickcam for notebooks pro). I want to be able to have them both run simultaneously and do some image processing with the images that I get from both cameras with labview and imaq vision.
As of right now, I'm having trouble getting both cameras to run at the same time. Any help would be gladly appreciated. Thanks.

The USB IMAQ driver will not support running 2 USB cameras at a time (I believe it is a limitation of the DirectShow interface). You could open one camera, acuqire an image, close the reference to that camera and then do the same for the second camera.
If you need simultaneous acquisition, look at possibly moving to 1394 cameras or analog cameras.

Can you attach a screenshot or link to the instructions you are following?
You are on the 3.6 release and Firefox 7.0.1 is out. You can download and install the latest release from http://www.mozilla.org/en-US/firefox/new/ if you would like to update now. The 3.6 version will be maintained for a while longer, but you should update when you can.
