Invoking a process in a different project & deployed on same engine

Hi,
I would like to know if we would be able to invoke a process with is already deployed in the engine from a new process. Please note that both the processes would be in different projects but will be deployed on the same engine. Also, we would like to avoid using any polling activity for this purpose and would want the process to get invoked like a process creation activity. Please let me know if anyone has tried this or have any idea for dealing with such situations.
Thanks,
Sree

You can do this using the process interfaces. The steps are.
1.- Create a process interface of the process that you are going to call that is in Project 1, select the process right button and generate process interface.
2.- Export this interface and import in your project (Project 2) that is going to be where you will call the process.
3.- Put a process creation activity that and put as the related process this interface.
In this way when you publish both projects in enterprise the interface is not going to be deployed, it will be deployed the real process and when the call is made it will call the real process of Project 1.
Hope it helps

How do I view multiple images from different projects at the same time?

Hello
I've been trying to find the answer in the user manual, but no luck so far.
I did find how to open 2 projects at once, but I can only see one image at a time in the viewer and I have to keep going back and forth between projects to compare images. (These are scans of old photos and I want to eliminate the ones that are poorer quality, so need to compare numerous images from 2 sets of scans)
How can I view an image from one project at the same time as an image from another? I know that it can be done in the same project by apple-clicking the second, third etc image, but this doesn't work if the images are from different projects.
Thank you
Elizabeth

Thank you again Tony
I've now created an album, independent of the projects, and dragged test images into it and it does just the job I needed. Now i just need to keep my brain sorted with which ones are which while i'm working

Two different projects in the same machine sharing some objects

Hello dear all
I got this scenario:
Same machine;
2 clients (70 and 80);
2 Projects
- AR Payment Process (prototype) for an existing company
- New company configuration
Coding Block (e.g.: for experiences in AR - prototype )
In the end - same Production machine
Projects running simultaneously
AR payment project (prototype) > New company configuration (in terms of duration)
Description
I got 2 projects running at the same time. At least somewhere in the time they will run simultaneously. One will consist in a new AR-Payment process for an existing company, and another one consisting in a creation of a new company.
So, Iu2019m afraid that those projects cannot run simultaneously once for payment process we will use coding block for sure.
We will have to change some standard tables (e.g. SPL Table) with different fields (two, to be more precise) u2026.. We do not have time to make one, and after another one, and then put them together and adjust it.
So, at this point Iu2019m not pretty sure about the direct influences, and in case of influence occur, what can be the solutions to avoid them.
Is there any way of controlling all the possible changes that will be made in the shared objects?
We really need to run these projects.
Thank you all in advance

The fastest way I can advice is...
1. edit your credits sequence (the clips you want to keep going as your credits roll)
2. nest the clips in a new sequence then you have a timeline with a nested sequence in your track 1...
3. Select your nested sequence in the track 1 and use the motion tab to scale/rotate/crop/move your image wherever you want in the canvas...
3. create a second track for your rolling credits...
4. create your rolling credits
5. if you have different clips for your rolling credits you may want to nest these too...
6. select your rolling credits and use the motion tab again to scale/crop/rotate/move your credits wherever you want in the canvas
Hope this help...

Could threads of a same process run on different CPU in the same time ?

Hello,
probably stupid question..., but I would like to understand if several threads inside a same process can run in the same time on separate CPU.
If the response is positive, how can I bind a thread on differant CPU using C API ?
Also what is the algorithm implemented by Solaris for the laod balancing ?
Is there any white paper on this subject ?
Thanks for any tips

Threads in the same process can run at the same time on separate CPUs.
You can bind a thread to a CPU using the processor_bind(2) API.
That algorithm is not public. You will have to wait for OpenSolaris so that you can look at the implementation at that time.
There is much public documentation on Solaris threading support on the web. Use google. The following document provides a good historical context of Solaris thread support.

Different Projects simultaneously accessing same footage

We are begining to edit a feature and we are under a big time crunch so we would like to have 2 editors working simultaneously on the film. I understand that you can't have the same project file open in two different workstations, but can you have 2 separate projects going that access the SAME footage on the SAME drive? Is that possible?
I know the foolproof way would be to duplicate all the footage onto new drives and just deal with them as separate edits, but we don't have the drive space for that.
Thanks for the help!

For two or more machines to access the same media you will need to look into a SAN setup. XSAN, SANmp, Meta SAN. None of these is cheap. The drives need to be Fibrechannel Raids...huge expense.
The cheaper route would be to get another set of drives and clone the footage from one set to another. Copy over everything...and name the new drives the same name, so there is no re-linking issues.

Invoking BPEL process from ADF application - webservice connection failed

Hi,
I am trying to invoke a Bpel process from ADF page , I deployed the same in Standalone SOA server since I had to display some Human Task Forms.
I created a webservice data control out of the bpel process and dropped the process method in my page.
The page on which I dropped the process method stopped rendering and I checked the logs and found that I got the error mesage- webservice connection failed,the webservice url could not be reached and in the logs it also asks us to check if the connections.xml is available in the meta-inf directory. I checked the conections.xml is available in the EAR.
So any pointers here and any one faced this error anytime?
is there better ways to invoke the bpel flow from ADF page.
Thanks,
Robin

Hi,
Check if your wsdl endpoint can accessed properly. If yes, check the soap-binding address is properly pointing to the server hosting the webservice.

Manage Modifications in process from different Projects

I am working 2 different Projects in my studio: Project A and Project B.
Both Projects have "n" processes assigned, but they have the same "Process x" being shared/called.
If I need to modify the "Process x", for example in Project A, how to guarantee that the modification will be made in the "Project B"?
There is a workaround?
Thank you!

Error in invoking a process in JBoss Cluster

Hi,
I have recently installed LC 8.2 on a JBoss 4.2.0 Cluster. The OS of the 2 cluster nodes are Windows 2003 R2 Enterprise Edition SP2.
And the database is SQL Server 2005 Ent. Ed. installed on another Windows 2003 R2 Enterprise Edition SP2.
I have created a simple process on the first node of the cluster. When I invoked the process through Workbench, I get ALC-DSC-003-000: com.adobe.idp.dsc.DSCInvocationException: Invocation error. with the following root cause:

How to invoke BPEL process from database?

Who can get an advice: what technology is better to use for invoking BPEL process, that is deployed to remote server, from database? What LIBs should I load into this database?
History: after successful trying Oracle RMI-example whith JDeveloper, I repeated the same had loaded my .jar and all listed in project Oracle .jar's into the database and received error "..class not resolved..".
Thank you.

How to invoke a process that is running in another Engine

Hi, All,
I looked through the OBPM 10.3.1 docs, I found "Subflow Activity" and "Process Creation Activity" can invoke a process that is running in another Engine. But in the OBPM studio, I cannot find any properties of both activities to configure this function.
Any ideas? Thanks in advanced.
Best Regards,
Bill

Hi Bill,
Brijesh is right. Although you cannot test it in Studio, there is a synchronous and an asynchronous way on Enterprise to create an instance in another process even though they are not in the same project.
1. For an asychronous (fire and forget) invocation of a subprocess (similar to the Process Creation activity), when you deploy to Enterprise you can use PBL to create an instance. Look at the Catalog's Fuego.Lib.ProcessInstance module and note the create() methods.
2. For a synchronous invocation of a subprocess (similar to the Subflow activity), you can create an instance in another process using the Dynamic Subflow property of the Subflow activity.
Hope this helps,
Dan

Deploying two projects at the same time

Hello,
We are two developers working on different web dynpro projects on the same J2EE-server, is it possible, using NWDS /WebDynpro to deploy simultaneously. At the moment both our NWDSs log in to the SDM as Administrator and locks it during the process.
Kind regards
Mattias

Cindy is right, but to answer your question, no, you cannot perform simultaneous deployments to a single J2EE engine. As you've found, SDM will only allow a single deployment at any given time.
Each developer should really have their own J2EE instance to avoid this sort of thing.

TNS:Operation Timed Out error while trying to invoke BPEL Process from sql

Hi,
I am trying to invoke a BPEL Process from PL/sql code. When i try to invoke the process, I am getting the following error message
ORA-29273 HTTP Request Failed
ORA:06512: at SYS.UTH_HTTP at line 1029

I have the SOA suite installed on my local machine...and the BPEL process that i am trying to invoke is deployed their.
Any idea what could be wrong..following is the code piece

Please advise

you are right the file adapter doesnt invoke any bpel
process, instead it is polling the file from
directory location?If it is polling for new files, shouldn't it create a new instance of the BPEL process automatically the moment it finds a new file? In other words, should a new file trigger an instance of the BPEL process rather than being started from PL/SQL?
Can this file adapter not be invoked as bpel process
in that case?The file adapter is part of a BPEL process. The BPEL process can be invoked from e.g. PL/SQL.
In this case this file adapeter return to an RECEIVE
activity...I think this receive cannot be invoked as
a BPEL process rite?Can you explain what you mean with this?
Also , will all synchronous request return "TIMEOUT"
error, if tried to invoke from pl/sql?Only if the synchronous process instance takes more time to complete (and thus to return) than the value specified for a time-out to occur. If the instance completes in for example 10 ms and the time-out time is specified as 30 seconds, no time-out will occur.

Authorization Error While Invoking BPEL Process Via RMI

Hi All,
I have been trying to invoke BPEL Process via RMI client.
I use the following piece of code for BPEL Process Invocation...

try {
locator = new Locator("default",jndi);
} catch (ServerException e) {
e.printStackTrace();
IDeliveryService deliveryService =

res = deliveryService.request("MyFirstBPELProject", "process", nm);
} catch (ServerException e) {
e.printStackTrace();
} catch (RemoteException e) {
e.printStackTrace();
Map payload = res.getPayload();
When I try to connect to my locally deployed BPEL process Manager and Invoke the same process (MyFirstBPELProjectProcess ) it works fine and creates an Instance on BPEL Process Manager Console.
When I tried Invoking the same BPEL process (MyFirstBPELProjectProcess ) deployed on a Remote machine ,it doesnt create an Instance.
I believe my connections settings are all correct ,since it doesnt give me an connection issue on my standalone client.
I tried looking at the following file default_group~oc4j_soa~default_group~1.log available opmn folder under SOA Suite OAS and there
are no errors.
Could some body point the log files that I need to look at.
I am sort of clueless...
Regards
Harish

CAn you post the error. HAve you made sure that the remote machine has connection on the port 6010. You can test this with the folloing command from the remote machine
telnet host 6010
obviously replace host with the fully qualified host name of the SOA machine.
cheers

Invoking bpel process from another bpel process in same app server

Hi,
When I invoke a bpel process from another bpel process in the same oracle AS
1. Is it a SOAP call or is there any optimization?
2. If there is some optimization where can I configure this?
3. Is there any similar optimizations if I invoke a bpel process from a
java application deployed in the same server? If so can you please provide
a sample?
Thanks for your help
Raj

By default the BPEL 10.1.2, it will do a local call to the process. It will not execute a SOAP request, no network access is done.
It can be configured at domain level:
Parameter: optSoapShortcut (SOAP local optimization)
Turns on "short-cut" for local SOAP request; local SOAP calls are normally done via an internal call instead of sending a message through the SOAP stack.
The default behavior for the engine is to optimize all. To disable optimization specify a value other than "true" or "yes".
