Process Flow - mapping not inserting data

I have a process flow that executes three mappings in sequence i.e Map1 -> Map2 -> Map3.
However, sometimes the process flow will execute and no data will be inserted by MAP2, other times it runs ok. If I run the mappings directly data is always inserted.
The only workaround I've found is to add a WAIT of 10sec between Map1 and Map2 in the process flow.
Has anyone come across anything like this and how did you work around or fix it?
OWB 10.2.0.3 btw.
Cheers

PS. transitions are ok.

Hi
If you have any map inputs make sure they are also declared in the processflow map - you basicly need to bind them.
You probably need to investigate from the beginning to understand your result of incoherent data.
What I would to first is.
1. Generete an intermediete code - choose your table as outgroup.
2. Review the code - are there any loading hints ?
3. Debug the map
Check your locations.
If everything seems right then the problem should lay on your workflow manager.
Remember that the workflow manager has only one namespace, so watchout for mapping name. I had strange executions on my PF because one of my maps had a "½" in the name.
Check the settings of the map - if you have enterd a set based run in your map and a row based run in the processflow.
Remember the setting in the processflow is the "superior" one
Just ideas what you can do.
Cheers

Calling process flow / mapping from comand line on client machine?

Looking to call a process flow / mapping from a commad line on the client machine. Online research has found some attempts at it, but nothing solid. I'd like to test this functionality so that I can eventually build these calls into a wrapper used by an enterprise scheduler.
Thanks

what oleg2 is writins is oke but I think
it is easier to write you one wrap around this sql-call, because then you have to parse some parameters and do other additional stuff

BDC not inserting data in mandatory fields of MM01

Suddenly My BDC for sales maintenance View is not working as it is not inserting data in Mandatory fields.?can any one tell me the reason

Hi Satyanarayan,
1. Check ur code in debug to see if your internal table contains value in mandatory fields
2. Try executing BDC program online to figure out the problem....
3. Check ur code to see whether u r assigning values to this fields...
Let me know if these things are ok in ur code...

Process flow/map performance issues

We have some issues with our OWB-based application and we're looking to find out if there are different ways we could be using the tool, or features/options we've missed.
We are trying to maintain a near real time feed of data from a front end system into our warehouse which was built using OWB 10.2.0.3 over a 10.2.0.4 database. The bulk of the application consists of OWB maps with a few hand-written PL/SQL objects, all executed in a series of hierachical OWB process flows. Maps/transformations are executed either sequentially or in parallel where the referential integrity of the model allows.
The problem is that we have around 150 tables in the datamart which could potentially require updating on each refresh cycle, although in practice only a few tables have any activity on a typical refresh cycle. The cycle consists of loading data into a set of staging tables, and from there the data is transformed into the main schema, often with multiple maps per target table.
On every cycle we run hundreds of maps, the vast majority of which process zero rows. Each map runs quickly and efficiently in its own right but collectively they add up to a 5 - 10 min cycle even if there is no data to process.
There are 2 avenues which we'd like to explore and would be grateful if anyone could provide any pointers/suggestions :-
1) It appears that each map opens and closes its own database session when it executes. I presume this was done because a single process flow could be constructed with maps executing in different target schemas, but we know that's not the case for us. We'd like to know if there is anyway to configure the database connection at a higher level (eg. process flow) so it opens a connection once and executes each of the maps (database packages) in that one session.
Our DBAs are experimenting with 'shared server' settings at a database level which may help to some degree but won't be the whole story.
2) Another option is simply to run less maps eg. load the staging area as now, collate stats on which staging tables contain new data, and then apply some logic such that subsequent maps only execute if the relevant staging table(s) contain(s) some new data, otherwise bypass that map.
We tried experimenting with the 'Pre Mapping Process' operator, but essentially that just generates another function call from the map package, so we still have the overhead of opening a database session for each map to run the package. Minimal gain.
We thought about adding a function call in the process flow before each map and then branching to either execute/bypass the map as approriate, but the function call still requires opening/closing of a database session each time so, once again, minimal gain.
What we really want is some way for a map or process flow to check without logging onto the database repeatedly.
Any ideas on the above, or other potential solutions anyone could suggest, would be greatly appreciated.

Process flows are not running in OWB

I have a process flow which has a main process and this main process calls 3 subprocesses and 1 externel process. This workflow was running fine and it suddenly stopped working and when I try to run it from WF monitor it is giving the following error.
Activity CALWINDW_INC_LOAD_PF_WE
Result Exception
Error Name -20001
Error Message ORA-20001: Task CALWINDW_INC_DELETE_PF does not exist. Please check that the ProcessFlow has been deployed successfully. ORA-01403: no data found
Error Stack Wf_Engine_Util.Function_Call(WB_RT_WORKFLOW_UTIL.EXECUTE_TASK, CLWNPKG, 200509200915, 37461, RUN).
I tried running it from OWB deployment manager but it didn't work.
I have checked all the process flows and the mappings all are deployed and all the mappings are running sepreatly. I tried dropping and deploying the process flow again and it deployed successfully without any error. We have tried rebooting the server, creating new PF location and new process flows, but nothing worked out. Becuase of this issue we can't run the whole process. Any help will be appriciated please.

May be your chain was in the wait at the scheduled time, as there were no adequate processes available at the app server to take up your job.
Check with your Basis ( and also your users ); about the optimal time to schedule the job and reschedule your jobs.

Can not insert Data

Hi all ;
when tryiing to call a stored procedure from java session bean ,i am getting this error message:
[BEA][Oracle JDBC Driver][Oracle]ORA-20000: Records are not inserted into the stagging table
ORA-06512: at "APPS3_MTNAOL.MTN_INV_MANAGER", line 2529
ORA-06512: at line 1
but when i am calling the same stored procedure from sql developper for test ,with the same input data, it is working fine. what can be the issue?

ORA-20000 is a user-defined Error in the database. Please check with whoever developed the code within your organization on what that means.
but when i am calling the same stored procedure from sql developper for test ,with the same input data, it is working fine. what can be the issue?Obviously, you are not able to recreate the error from 'sql developer'.

Could not insert Data in to the table

hello friends
I have some pbm in inserting values in to sqlserver database table.I could not insert values to the
table having varchar datatype fields.partyType is a field name of varchar type.when i try to insert
"LCL" for that field it throws following exception.
java.sql.SQLException: [Microsoft][ODBC SQL Server Driver][SQL Server]The name 'LCL'
is not permitted in this context. Only constants, expressions, or variables allowed here. Column
names are not permitted.
sometime it throws

Running of process flow does not show any Active session in Database

Hi Team,
I am running a process flow in OWB 11g ( From Design Center ) which is having around 100 maps within it. However, from Control Center I can see the Process Flow is running ( i.e. Green check is visible beside the process flow) but when I run SQL query in backend database ; I am unable to see any running object ( i.e. OWB map name as package object) there corresponding to this Process Flow
I am running the below query to check the availability of running session :-
SELECT A.LOGON_TIME,A.SID,B.OBJECT_NAME,A.*
FROM gv$session A, dba_objects B
WHERE A.PLSQL_ENTRY_OBJECT_ID = B.OBJECT_ID
AND A.STATUS = 'ACTIVE'
Could you please suggest if this is something wrong in the development of the Process Flow or we can`t see any running map there in backend when we execute any process flow from OWB ?
Thanks in advance
Nilava Sen

Try below query
select sid,module,program,status,sql_id from gv$session where status='ACTIVE';
select * from gv$access;

JDBC Not INSERTING Data

Hi All,
I'm having a real problem with the below method titled Not Working:. This method will INSERT data into a MS Access data base all day long, but it will always insert it at the same record. It never actually creates a new record, inserts the data and then saves that record. However, the second code example that I have titled Working: will create a new record, insert the data and then save the record. What is wrong with the Not Working code? I can't figure it out.

If one works and the other doesn't, then they must generate different SQL statements. My idea (blatantly obvious as it may sound) would be to actually look at those statements, rather than wasting time looking at the code that generates them.

Could anyone please help me to fix this?

The issue was resolved by renaming the workflow. What is learned here is, we should not have same workflow name for two different workspace.

Process flow is not working for both workspace.

Hello, I really need help. I have prodution issue now. I am using OWB 11g version.
I have two wokspace running on the same database.
Workspace names are MSSTATE_OWBOWNER, IAEBT_OWBOWNER.
The automatic job is not kicking of on both. I scheduled MSSTATE workspace at 12:10 AM, IASTATE workspace at 12:50AM.
MSSTATE workspace starts automatically at 12:10AM. But IASTATE does not start 12:50AM. Actually job starts and gettting the below error message.
RPE-02083: Process PF has errored Activities. Dependent objects may not have been deployed. You can use Oracle Workflow Monitor to retry the activities or abort the Process
I redeployed the workflow on IASTATE and manually started. But when i go to MSEBT, i see the same problem and get the below error message.
RPE-02083: Process PF has errored Activities. Dependent objects may not have been deployed. You can use Oracle Workflow Monitor to retry the activities or abort the Process
If i fix one state, other one breaks. I could not run both state through scheduler. I think, the job is valid and enabeld. But workflow is breaking...
One thing i noticed is, we have same process flow names on the both workspace. Is that causing a problem?
Any help is highly appreciated....

Not inserting date field-very urgent

thanks in advance any help appreciated
im getting all the datas in csv as an array and inserting using the insert method, the date(not datetime) field is not inserting (vb.net), and not showing any error
im getting the datas as array string wat iv to do while inserting ive used all the conversion techniques but still not inserting

Hi,
You must indicate the "specified" attribute in order to inset or update any field that is not string type.
For example, I guess that your program do something like:
obj.date=%%date expression%%
but you must do also:
obj.date_specified=true
That is for any field like number, date, boolean, etc...that is not a string.
Hope it helps.

SQLJ with EJB. Do not insert data in the database

Hi All!
I4m developing an application using SQLJ and EJB (session beans,
container managed transactions), and when I try to insert data

the changes do not have effect in the DB.
I've tried to use bean managed transactions, but when I try to
insert data, I get the error: NOT IN A TRANSACTION. The code of
the client in the bean managed is the following:

String username = "xxx";
String password = "xxx";
// Setup the environment
Hashtable environment = new Hashtable();
// Tell JNDI to speak sess_iiop
environment.put

hello.MiBean remoteInterface = homeInterface.create();
ut.begin ();
remoteInterface.inserta();
ut.commit();
catch (Exception e) {
System.out.println(e.getMessage());
e.printStackTrace();
I4m waiting for suggests.
Thanks in advance...

Hi,
Are you sure it's a front-end bug? Try to double check your back-end code.
If you still believe the bug is in the front-end, try to debug the insertHandler function to see if you are attaching the UserVO properly into the UserEvent.
Best regards,
