Pass output parameter from mapping to external process in a Process Flow

In Process flow, how do we pass an Output parameter from a mapping (generated by a post mapping operator) into an external process (shell script)?
I have a mapping that generates an output parameter and I would like to pass this parameter to an external process (a shell script) with a process flow. Is this possible?

Hi Norman,
Unfortunately in the current release, you cannot do this. What you can do, is store the value into a table and read it in the external process, or write it into a file and read it from there. The next release will support passing output parameters from one activity to the next.
Thanks,
Mark.

Passing parameters from mapping to mapping with in process flows

I am new to OWB and i would appreciate if any one can suggest me on how to solve the issue i have.
I am trying to pass a parameter from one mapping to another mapping.
ex: key need to be passed
start ----->A--->B--->C----->END
B needs to pass the key to mapping C
In B i have mapping Out put parameter and in C i have a mapping input parameter.
In process flow palatte i could see Key as OUT and in C properties i could bind it to Key .
but i try to deploy this mapping i am getting error below
PF_PKG Create Error
RPE-02040: Internal error: KEY cannot be converted to a constant value. Please correct the value. If the problem persists then please contact Oracle Support with the stack trace and details on how to reproduce it.
TEST_PFCreate INFORMATIONAL
RPE-02071: Deployment has been aborted due to a previously reported critial error.
please suggest me how to pass parameters between mappings with in a process flow.

Hi
You have to use process flow variables. So the output of map A, say parameter P would bind to variable V and then the input of map B, say Q would bind to variable V. In this way you can push parameters from one activity to the other. Although the UI lets you bind B.Q to A.P, it should not, I think there is a bug reported on this.

How to pass a parameter from one action1 in block1 to action2 in block2.

Dear Experts,
How to pass a parameter from one action1 in block1 to action2 in block2.
My Process Structure is as follows..
       Process
            Sequential Block
                 Action 1
                 Parallel Dynamic Block
                         Sequential Sub Block
                         Action 2.
while i am trying to execute the action1 the following error is shown below:
Cannot complete action: The activity could not be read.
Please suggest me how to do?
Regards,
Rajesh N

Hello Rajesh!
I think you are talk about the mapping parameters of your process.
This case in design time of your workflow, you have the vision of your blocks and actions, you have on action 1 the output parameter and you have the action 2 an input parameter.
So you have that make a group mapping on your process, map in this group the action1 outpu parameter with the action2 input parameter.

OWB | Passing input to mapping in the process flow

Hi,
I have a process flow which calls a stored procedure which returns 2 values.
I want to use the values returned from this procedure as an input in my mapping. My mapping has Mapping_Input_Parameters definined for these two inputs.
These values are going to be load_date and the batch it belongs.
I have created new params in the process flow edit under the mapping. The process flow executes successfully if I give the input params as a constant. When I do a binding with the out variable of the stored procedure I get a deployment error as "Internal error: OUT_D_LOAD_DATE cannot be converted to a constant value. Please correct the value. If the problem persists then please contact Oracle Support with the stack trace and details on how to reproduce it."
Please let me know how to resolve this and if there is way to get the load_date in the mapping without actually having to call the procedure in the mapping. The load_date will change everyday and I need to read it from a table.
Thanks!

Hi
If you have resolved the error please guide me also Since I am also facing the same error. (RPE-02040: Internal error: MYRAND cannot be converted to a constant value. Please correct the value. )
I am using 10gR2, Here my test process flow is
Start - > MyRand -> FindOddEven->end
Here MyRand function will return a value, the function findOddEven will just do a mod of 2 and return 1 for odd numbers and 0 for even numbers. When I bind the OUT parameter of the MyRand to the IN parameter of the FindOddEven it is throwing the same error.
Thanks in advance

Passing a parameter from one class to another class in the same package

Hi.
I am trying to pass a parameter from one class to another class with in a package.And i am Getting the variable as null every time.In the code there is two classes.
i. BugWatcherAction.java
ii.BugWatcherRefreshAction.Java.
We have implemented caching in the front-end level.But according to the business logic we need to clear the cache and again have to access the database after some actions are happened.There are another class file called BugwatcherPortletContent.java.
So, we are dealing with three java files.The database interaction is taken care by the portletContent.java file.Below I am giving the code for the perticular function in the bugwatcherPortletContent.java:
==============================================================
public Object loadContent() throws Exception {
Hashtable htStore = new Hashtable();
JetspeedRunData rundata = this.getInputData();
String pId = this.getPorletId();
PortalLogger.logDebug(" in the portlet content: "+pId);
pId1=pId;//done by sraha
htStore.put("PortletId", pId);
htStore.put("BW_HOME_URL",CommonUtil.getMessage("BW.Home.Url"));
htStore.put("BW_BUGVIEW_URL",CommonUtil.getMessage("BW.BugView.Url"));
HttpServletRequest request = rundata.getRequest();
PortalLogger.logDebug(
"BugWatcherPortletContent:: build normal context");
HttpSession session = null;
int bugProfileId = 0;
Hashtable bugProfiles = null;
Hashtable bugData = null;
boolean fetchProfiles = false;
try {
session = request.getSession(true);
// Attempting to get the profiles from the session.
//If the profiles are not present in the session, then they would have to be
// obtained from the database.
bugProfiles = (Hashtable) session.getAttribute("Profiles");
//Getting the selected bug profile id.
String bugProfileIdObj = request.getParameter("bugProfile" + pId);
// Getting the logged in user
String userId = request.getRemoteUser();
if (bugProfiles == null) {
fetchProfiles = true;
if (bugProfileIdObj == null) {
// setting the bugprofile id as -1 indicates "all profiles" is selected
bugProfileIdObj =(String) session.getAttribute("bugProfileId" + pId);
if (bugProfileIdObj == null) {
bugProfileId = -1;
else {
bugProfileId = Integer.parseInt(bugProfileIdObj);
else {
bugProfileId = Integer.parseInt(bugProfileIdObj);
session.setAttribute(
("bugProfileId" + pId),
Integer.toString(bugProfileId));
//fetching the bug list
bugData =BugWatcherAPI.getbugList(userId, bugProfileId, fetchProfiles);
PortalLogger.logDebug("BugWatcherPortletContent:: got bug data");
if (bugData != null) {
Hashtable htProfiles = (Hashtable) bugData.get("Profiles");
} else {
htStore.put("NoProfiles", "Y");
} catch (CodedPortalException e) {
htStore.put("Error", CommonUtil.getErrMessage(e.getMessage()));
PortalLogger.logException
("BugWatcherPortletContent:: CodedPortalException!!",e);
} catch (Exception e) {
PortalLogger.logException(
"BugWatcherPortletContent::Generic Exception!!",e);
htStore.put(     "Error",CommonUtil.getErrMessage(ErrorConstantsI.GET_BUGLIST_FAILED));
if (fetchProfiles) {
bugProfiles = (Hashtable) bugData.get("Profiles");
session.setAttribute("Profiles", bugProfiles);
// putting the stuff in the context
htStore.put("Profiles", bugProfiles);
htStore.put("SelectedProfile", new Integer(bugProfileId));
htStore.put("bugs", (ArrayList) bugData.get("Bugs"));
return htStore;
=============================================================
And I am trying to call this function as it can capable of fetching the data from the database by "getbugProfiles".
In the new class bugWatcherRefreshAction.java I have coded a part of code which actually clears the caching.Below I am giving the required part of the code:
=============================================================
public void doPerform(RunData rundata, Context context,String str) throws Exception {
JetspeedRunData data = (JetspeedRunData) rundata;
HttpServletRequest request = null;
//PortletConfig pc = portlet.getPortletConfig();

/*String userId = ((JetspeedUser)rundata.getUser()).getUserName();//sraha on 1/4/05
String pId = request.getParameter("PortletId");
PortalLogger.logDebug("just after pId " +pId); */
//Calling the variable holding the value of portlet id from BugWatcherAction.java
//We are getting the portlet id here , through a variable from BugWatcherAction.java
/*BugWatcherPortletContent bgAct = new BugWatcherPortletContent();
String portletID = bgAct.pId1;
PortalLogger.logDebug("got the portlet ID in bugwatcherRefreshAction:---sraha"+portletID);*/
// updating the bug groups

//String pId = pc.getPorletId();
PortalLogger.logDebug("just after pId " +pId);
PortalLogger.logDebug("after getting the pId-----sraha");
result =BugWatcherAPI.getbugList(profileId, userId);
PortalLogger.logDebug("select the new bug groups:: select is done ");
context.put("SelectedbugGroups", profileId);
//start clearing the cache

if (((JetspeedRunData) data).getCustomized() == null)
ActionLoader.getInstance().exec(data,"controls.EndCustomize");
catch (Exception e)
PortalLogger.logException("bugwatcherRefreshAction", e);
===============================================================
In the bugwatcher Action there is another function called PostLoadContent.java
here though i have found the portlet Id but unable to fetch that in the bugWatcherRefreshAction.java . I am also giving the code of that function under the bugWatcherAction.Java
================================================
// Get the PortletData object from intermediate store.
CacheablePortletData pdata =(CacheablePortletData) PortletCache.getCacheable(PortletCacheHelper.getUserHandle(
//rundata.getRequest().getRemoteUser()));
((JetspeedUser)rundata.getUser()).getUserName()));
pId1 = (String)portlet.getID();
PortalLogger.logDebug("in the bugwatcher action:"+pId1);
try {
Hashtable htStore = null;
// if PortletData is available in store, get current portlet's data from it.
if (pdata != null) {
htStore =(Hashtable) pdata.getObject(     PortletCacheHelper.getUserPortletHandle(
((JetspeedUser)rundata.getUser()).getUserName(),portlet.getID()));
//Loop through the hashtable and put its elements in context
Set storeKeySet = htStore.keySet();
Iterator itr = storeKeySet.iterator();
while (itr.hasNext()) {
String paramName = (String) itr.next();
context.put(paramName, htStore.get(paramName));
bugwatcherRefreshAction bRefAc = new bugwatcherRefreshAction();
bRefAc.doPerform(pdata,context,pId1);
=============================================================
So this is the total scenario for the fetching the data , after clearing the cache and display that in the portal.I am unable to do that.Presently it is still fetching the data from the cache and it is not going to the database.Even the portlet Id is returning as null.
I am unable to implement that thing.
If you have any insight about this thing, that would be great .As it is very urgent a promt response will highly appreciated.Please send me any pointers or any issues for this I am unable to do that.
Please let me know as early as possible.
Thanks and regards,
Santanu Raha.

Have you run it in a debugger? That will show you exactly what is happening and why.

Passing a parameter from one form to another

Hi
I'm trying to pass a parameter from one form to another. I've read lots of postings about this, and I have succeeded in calling the second form using code behind one of the existing Portal buttons (insert). Here is the code:
DECLARE
pro_id NUMBER;
pro_link VARCHAR2(1200);
BEGIN
pro_id := p_session.get_value_as_number(
p_block_name => 'DEFAULT',
p_attribute_name => 'A_PRO_ID');
pro_link := portal30.wwv_user_utilities.get_url(
'CINTRA_APP.PRO_LINK_1',
'WKG_PRO_ID',pro_id,
'_WKG_PRO_ID_cond','=');
PORTAL30.wwa_app_module.set_target(pro_link,'CALL');
END;
Trouble is, the parameter does not get passed. This could be because:
the field I'm trying to populate is based on an LOV ?
the target form is not set up to receive parameters? (I read this somewhere, but how do you do it?)
Thanks
Manfred

Passing a parameter from a web application to the sub report.

Hi I am currently passing a parameter from the webpage into the main crystal report. I would like to pass this same parameter to the subreport but when I right click on the subreport from the main report I can find the parameter on the main report but there is nothing to link it to on the subreport (since this window just shows the dataset). I also tried adding a parameter to the subreport but it does not show up in the link window on the (select data in subreport to link to). I am using vs2005 and the crystal reports that comes with this.
Thanks.

Hi, Paul;

Pass a parameter from webi to Xcelsius

Hi all,
Anybody knows how to pass a parameter from a webi report to Xcelsius via URL?
I need to refresh the Xcelsius data with a parameter coming from the webi report. With Live Office works but only the first time: the data is not being refreshed in Xcelsius everytime I change the parameter in the webi report.
I'm thinking in someting like openDocument.jsp but how do I read this parameter in Xcelsius? Which connection should I use?
Thank you very much,
jon

Hi Peter,
the link provided refers to Xcelsius V4.5.
In Xcelsius 2008 you have to control Flash Vars in the Data Manager.
Go to the Data Manager, Add the Flash-Var Connection Type, Select CSV-FlashVar and define a name and a range.
But i am not sure if Xcelsius Engage can handle FlashVars, because i am only working with Enterprise.
Please take a look at your manual.
For sure there are other ways to import data during runtime. Take a Look at the Connections provided by Data Manager. (e.g. QaaWS, SSRS, LiveOffice, Webservices, ...)
Also take a look at the link below. It might be another nice option for "pseudo" data connectivity

Pass a parameter from one ASP portlet to another ASP portlet

We are trying to pass a parameter from one ASP portlet to one or more other ASP portlets.
We are using PDK-URL Services and have created a provider.xml for each of the ASPs and the ASPs work as normal within the portlets created.
We are now trying to use PDK-URL Services to pass parameters to a portlet. As a first step we set up a portlet which displayed an ASP, this ASP (and the portlet) expected a parameter. If the parameter value is left blank the Portlet displays a default page (not the ASP page) for passing in the parameter i.e. a text box and a submit button. If the parameter is entered and submitted the ASP page returns and the results of the query are based on the parameter typed in.
As the next step what we are now trying to do is pass a parameter from one ASP portlet to another.
The Documentation says that there are two types of parameters Qualified where Parameters will be passed only to the initiating portlet i.e., portlet which contains them and Unqualified where all portlets will be affected by the parameter sent by any portlet.
Very little information was available on this, apart from the one liner explanation of each (above).
When we tested the above, using the PDK sample ("ParamCustomizationPortlet") portlets it doesn't appear to be doing anything in particular.
Any ideas on the best approach to passing parameters from one ASP portlet to another?
Thanks for your time.

We can visualize Qualified and Unqualified parameters only when there are multiple portlet instances in a single page. For example, add two instances of ASP portlet you have created, and submit from one portlet. You can see the other portlet also receiving this parameter, provided you are using unqualified parameters.
Thanks,
Amjad.

Disable particular Mapping Execution in Process flow

Hi,
I am working on OWB 11gR2. I want to disable the execution of a particular mapping in the Process flow. For example, there are 4 mappings A,B,C,D which run one after another,I want to disable the execution of mapping C alone.Is this feature available in OWB?
Please Advice.

Unfortunately this is not handled OutOfTheBox.
You would probably need one or two things extra to do this properly:
-create a table and a procedure/function that holds the mapping names together with a flag.
-use a function operator in the process flow to retrieve a mappings flag from above specified table and store it in a variable in the process flow
-use condtional transitions to route the flow either tru or alongside the mapping. use a reference to the variable used previously.
-make sure the flow can exit properly when you use conditional transitions.

Binding mapping in a process flow

Hi,
This is the first time i am creating a process flow. I have kind of figured all the stuff out but i get 1 error in validation. i pulled the mapping into the process flow and named it but i donot know how to point it to the mapping in a particular location. is there something i need to do for this. I get the following error when i validate.
mapping_name's bound object null of null type???has been deleted.

How to pass process flow input parameter to unix script external process

Hi,
I'm trying to pass a process flow input paramter (string) to an external process which is a unix script. I've been working on this for the last 2 days but can't get it to work. Here is the design. I have a process flow with 3 maps that create a file in the unix file system. I have a suffix, which is an input parameter to the process flow, that will need to be passed to the unix script to rename the file appending the suffix to the filename. I've tried different things and nothing works for me. Has anyone done something similar in OWB?
Thanks much!

I tried using useBean inside the Jsp for this.
But following error comes:

Mapping audit_id in process flow with parameter

Hello!
I have a following request.
I would like to get AUDIT_EXECUTION_ID for certain Mapping in process flow and pass this ID to next mapping (all this with help of parameters I guess??) to get some data from AUDIT tables. How to do this?
OWB version 10.2.0.1
Thank you Gorazd
Edited by: gor on May 9, 2011 1:40 PM

Hi,
It is a bit complicated and technical.
Will give you a hint.
You need to install run_my_owb_stuff as a function, grant access, and create a public synonym.
Then within you have to add capturing of the execution_id as an additional custom parameter. (see below).
Once done. Add a Start parameter with same name to each Process Flow, and Bind it to any activity that you want to use the parameter with.
-- Override Parameters
dbms_output.put_line('Stage 3: Overriding Parameters');
-- override_system_input_params(l_audit_execution_id, p_system_params);
if p_task_type='PROCESS' then
-- GRI addition
     l_custom_params := p_custom_params || ', p_execution_id=' || l_audit_execution_id;
override_custom_input_params(l_audit_execution_id, l_custom_params);
else
     override_custom_input_params(l_audit_execution_id, p_custom_params);
     end if;
-- override_custom_input_params(l_audit_execution_id, p_custom_params);
