Cancelling an async call in parallel flow activity

Hi all,
As known, each branch of a parallel flow activity must be completed for rest of the BPEL execution continues. Let me expose a scenario:
Imagine you need to get the current market value of the euro. You have 3 different sources of information that deliver the same result. Using parallel flow activity, you perform calls to these 3 sources. Once the first source calls back, it´s not necessary to wait for the others callback, because you already have the information that you need in your hands. How can I cancel the other waiting async calls? In WLI, we set up the parallel flow as AND or OR type. Using AND (+) means that all branch must be completed so that the process continues. Using OR (-) means that once the first branch is finished, the others will be ignored (cancelled) and the process continues. How can I get the same feature in BPEL?

Hi Gustavo,
There may be easier way to do this, but somehow it's not striking at the moment. In the meantime, you can try the following and see. If i get more robust and easier solution, i'll post it here.
Just thinking aloud here:
1) Throw a fault e.g. ResponseRecieved in each branch as soon as the branch recieves a response. The fault has to be handled in a fault handler associated with a scope containing the parallel flow. You can leave the fault handler "empty" (no-oos) and proceed with the rest of the activities.
The above should allow the control to proceed with the activities next to the flow.
OR
2) In each flow, as soon as you receive a response after receive activity, invoke a callback port type of the rest of the asynchronous calls and send a dummy callback message. This should mark the completion of the receive activities in other branches. I think correlaiton needs to be handled here.
Please try if you have not already done so and let me know.
Thanks-

NonBlockingInvoke in Flow Activity

Hi I know that setting "NonBlockingInvoke" property to true to one of the partnerlinks in a flow activity will bring in a new transaction/thread to execute the flow in a real parallel manner. What exactly is the drawback if we dont set this property other than that we will have sequential execution.
Please let me know...

yup per default they are executed one after the other ..

Hyperlink in Work-flow activity

Hi all I want to pass a hyperlink in Work-flow activity
I am getting problem when my URL is more then 66 0r in sometime 77 characters it that.
It is adding %20%20 in between the URL if it is having more then 66 characters .

Flow Activity Exception Handling Problem

Hi,
I am using Flow Activity in my Bpel Process, i am getting some exception in one of flow, but other flows are working fine. Even i have included Catch block for other flow still i am getting fault response.
Please suggest me how to do exception handling in Flow Activity.
Thanks in advance.

Hi,
just restructure your BPEL process. The 'Flow' activity contains several 'Sequence' activities. Simply ... put a 'Scope' activity inside of each 'Sequence' activity. Then put another 'Sequence' activity inside of each 'Scope' activity ... and put there required logic/activities.
After that you can create fault handling on these 'Scope' activities. In this way you can handle faults in each flow-sequence.

Martin

Guru...

After the flow is executed, you have the response variables from the individual partner link , create a variable of type unbounded xsd, assign xml fragment to this variable. This should be equal to the number of flows.
for example if you have 3 flows your xml fragment should be like:- create order element three times...
<CreateStatusEle>
<CreateOrder>
<orderNumber></orderNumber>
<status></status>
<CreateOrder>
<CreateOrder>
<orderNumber></orderNumber>
<status></status>
<CreateOrder>
<CreateOrder>
<orderNumber></orderNumber>
<status></status>
<CreateOrder>
</CreateStatusEle>
once this assign is done then use assign to assign values to this xml like : OutfromPartnerLink1/../OrderNumber -->$unboundedvaraible/CreateOrder[1]/orderNumer ....
$unboundedvaraible/CreateOrder[2]/orderNumer and so on....
This a crude way of doing it.. but you will achieve what you r trying to.. also since you know how many partner links this should be doable...
will let u know if i can think of better approach...

Flow activity sleeping

Hi,
Sometimes the BPEL process sleeps for 1-3 minutes in the flow activity before executing the branches.
What could be the problem with the flow activities?
I know the flow branches are executed by a single thread and also we did not enable parallel execution.
But the problem is why is it sleeping before executing the branches?
Cheers,
Ravi

the problem is
Instance1 --> starts --> struck in middle
Instance2 --> starts --> struck in middle
Instance3 --> starts --> struck in middle
InstanceN --> starts --> struck in the middle
after few minutes
Instance1 --> resumes
Instance2 --> resumes
Instance3 --> resumes
InstanceN --> resumes --> end
Instead of this I want the server to behave like
Instance1 --> starts --> ends
Instance2 --> starts --> ends
There should not be any break in the middle. When the load is high the server should put the new process creation on hold.
The BPEL server is very frustrating. I would rather use sqlloader and dblink.
Thanks,
Ravi

When a process flow activity takes a long time to run.

Hello,
I have a process flow activity that sometimes takes a long time to run so that the process flow never ends. Is it possible that I can set the activity so that during a certain time that this has not been executed automatically flow process to continue?
I'm Using Oracle Warehouse Builder 11g on Windows Server 2003 R1.
Greetings and thanks.

What I've done in the past is just use a small polling procedure (PL/SQL) and a conditional transition in the process flow, depending on what the proc returns (Continue or Fail) then the flow of control in the Process is changed.
I think the key also is to not have too much paralellism going on too, that way it's easy to streamline the PF and remove slow moving processes to a more linear path (stopping bottle necks on your logical AND).

How to get the package name of a procedure used in a process flow activity

Hi all. I'm on OWB 11.2.0.2.0.
When I used a packaged procedure or function in a mapping operator, I can find out the package.program_unit name by getting the operator's FUNCTION_NAME property. For example,
OMBRETRIEVE MAPPING '$mapName' OPERATOR '$operName' GET PROPERTIES (FUNCTION_NAME)
But when the same is used in a process flow activity, I can't find a property name that will give me the same information. I can get the BOUND_NAME, it does not tell me the package name. It must be stored in the activity properties because when you pull up the Synchronize dialog for the activity, it knows the package name.
Is there a way to get this via an OMBRETRIEVE?
Thanks.

ANA, this is exactly what I needed. Thank you so much. I saw REFs also in the OMBRETRIEVE MAPPING/OPERATOR syntax, but went cross-eyed trying to figure out if I could use the same there. The closest I found was GET BOUND_OBJECT.
Thanks again!

A theory about trees (ApEx 4.0) regarding save activated node

Hallo all!
Can someone please confirm (or not) my theory about trees regarding save activated node in ApEx 4.0(.1):
With my first tree I tried to set a varchar2-value for the last selected node ... didn't work. After many tries I was succesful with changing this to a numeric value...
...Is this a bug or a feature? ;-)
Btw.
Another supposing regarding the source-code of trees is that this can't be longer than 4000 bytes. Is this right?
And if so ... can I put a Funktion in there that returns the statement (like in classic reports, but with static row-structure)?
Hope this time someone out there is attends my thread.
With kind regards...

Hi,
Pre-Apex4 you could make use of the A1 and A2 columns in the tree SQL along with the tree template to conditional set the color of the node text. Does anyone know how to achieve this in Apex4? I've tried using the tree SQL shown below but this displays the HTML (SPAN tags) as text.
select case when connect_by_isleaf = 1 then 0
            when level = 1             then 1
            else                           -1
       end as status,
       level,
       '<span style="color:red;">'||"ENAME"||'</span>' as title,
       null as icon,
       "EMPNO" as value,
       null as tooltip,
       null as link
from "#OWNER#"."EMP"
start with "MGR" is null
connect by prior "EMPNO" = "MGR"
order siblings by "ENAME"Any assistance would be appreciated.
Cheers.

Parametized USER_DEFINED process flow activity

Can someone help? I am attempting to use USER_DEFINED process flow activity to copy a file to another location under a new name.
The names for the source and destination file will be generated at execution time by a mapping that will create the file.
The challenge is how do I pass these file names a parameters; a, b to a file copy script I have written.
You help will be appreciated.

This should be possible as we have done a similar thing.
How are the source and destination files generated in the mapping ?
As our file information was stored in an Oracle table we created a Transformations/Function that queried out the required information (filenames) and formatted it into the required statement for execution.
This was stored in a variable and could then be passed to the user defined process in the Process Flow.

Parallel processing using flow activity

Hey, I have two input directories in the same process for two different partnerlinks and I want to use these two directories to input two flat files to two tables simultaneously.I tried using flow to do this parallel process. But the process when uploaded onto the console takes one input file and it fails. It changes the state of the process to 'off'. Can anyone let me know as to what could be the reason? thanks and regards

Hi can someone help me please

Process flow Activity File Exists

Hi
Software: warehouse builder 11.1.0.7
OS: Redhat 5.5
DB: 11gR1
I am trying to use the activity "File Exist" on a process flow to know if a file does exist, with two transitions
one with condition "EXISTS" that ends in success and one with the condition "MISSING", when the file
exists the process flow acts normal with end success, but when the file doesn't exist the process flow
just hangs and doesn't finish.
Am i missing some configuration?

You have to provide multiple transitions (arrows) out of the file_exists activity and the define the transition conditions (in the transition view section of the window) for success and error. In that case, if the file exists, the flow will continue along the sucess transition path, if it doesn't it will continue down the ERROR path. The error path can then end up into an END_ERROR activity and that will make the process flow stop if the file is not found, just your expected behaviour.
If you have only a single unconditional transition (arrow) out of the file_exists, the process flow will continue regardless of the FILE_EXISTS activity.

Process flow - Active Directory integration with Enterprise Portal

Hi
I have seen number of documents/forum discussions on integrating Microsoft Active Directory (LDAP) with Enterprise Portal, but unable to find out the process flow for achieving the same.
I have installed Enterprise Portal 6 (SP13) running on Web AS 640 (J2EE Standalone). The UME is currently configured to use Java database. (i.e datasourceconfiguration_database_only.xml)
I intend to proceed as below for integrating with Active Directory and integrate with Windows authentication:
1) Configure UME to use an LDAP Server as Data Source using Config Tool
http://help.sap.com/saphelp_erp2004/helpdata/en/cc/cdd93f130f9115e10000000a155106/frameset.htm
2) Configure Enterprise Portal UME i.e http://<host name>:50000/irj - System Administration - System Configuration - UM Configuration
<b>Should I configure Data Sources & LDAP Server here as I have already configured these using J2EE Config tool (point no.1).</b>
3) Integrate Windows authentication with EP using IISProxy module.
I hope the above will enable me to logon to Portal without supplying username and password once you are logged on to the PC using your Windows user name and password.
Also, any schema updates required to Activie Directory i.e What additional data is stored in A.D.
I would appreciate your guidance on this.
Thanks in advance,
Chandu

Hi Chandau,
you wanted that some users are not taken into account by the User Management Engine (UME).
This behavior can be established by specifying the
ume.ldap.negative_user_filter property for the LDAP data sources in the data source configuration file. Using this property one can define that all users and accounts that
match the defined conditions are filtered out by the UME API.
A detailed documentation can be found in the SAP Online Help:
http://help.sap.com/saphelp_nw04/helpdata/en/9a/f43541b9cc4c0de10000000a1550b0/
content.htm
In the following example of a data source configuration file for Microsoft Active Directory
Server the attribute userPrincipalName is used as Logon ID of a portal user id (j_user).
Here the user accounts that have one of the following Logon IDs (index_service,
notificator_service and cmadmin_service ) are filtered out.
<dataSources>
</dataSource>
<dataSource id="CORP_LDAP">
<privateSection>
<ume.ldap.negative_user_filter>
userPrincipalName=[index_service,notificator_service,cmadmin_service]
</ume.ldap.negative_user_filter>
</privateSection>
</dataSource>
</dataSources>
