Transformation in Process Flow

hi
I am using owb 11g and i am seeing some existing code which has been built by some one.
In Process Flow, i couldn't see any Procedure name and their parameters, Could you some one let me know where i can find those stuff in 11g.
thanks

In process flow, left click on the procedure you want to see (select it) and than go Edit--> Synchronize and you'll see where it is in repository.

Transformation in a Process Flow

Hi there,
I am trying to use a transformation in a process flow and I am getting the following error -
RPE-02040: Internal error: SOMEFUNC cannot be converted to a constant value. Please correct the value.
I have a PL/SQL function SOMEFUNC(x, y) that takes two values and returns a varchar2(10). I imported this function as a transformation with the same name. The mapping after this takes a varchar2(10) as input.
As soon as I bind the input parameter of the mapping following this transformation, I get the above error. If I don't bind it, then there are no errors but that is not useful to me. I need to pass in the return value of this function to the mapping that follows it.
Has anyone been able to do this successfully? How did you get it to work?
This is OWB 10.2.0.2.
Thanks

Thanks for that link David,
that does explain some things but unfortunately I am still running into the same problem.
So here is what I have -
Start -> Transformation -> Assign -> Mapping -> End_Success
I could not see any way to add a variable in OWB 10.2.0.2.8. You could do this earlier from the Start operator but there is no such option in this version. The Assign operator seems to be designed for this.
I bound the mapping for Assign input value to Transformation's out bound value. And I bound Mapping's input parameter to Assign's output variable. I then validated and generated this process flow successfully. However while deploying, I still got -
RPE-02040: Internal error: Transformation cannot be converted to a constant value.
My OWB client version is 10.2.0.2.8 and repository's version is 10.2.0.2.0. Have you run into this problem before?
Thanks

Process Flows Transforms

Hi,
I'm trying to include a PL/SQL function into a process flow from the public transformations. Whenever I validate the process flow it reports the error "VLD-10019 ... Function needs a valid deployment location". But I can't find anywhere to define the location of the public transformations, anyone know what I'm missing ?
Cheers
Pavel

Hi Pavel,
Did you take a look at the configuration for the process? Right click on the process and open configuration. In there you will see your activities.
Go to the activity node and open this, then you will see a setting called "deployed location". Set that to the location your transformation is located in. Typically this is your target location.
Hope this helps,
Jean-Pierre

Transform activity in Process Flow

Hi Guys,
After wasting hour trying to get the SQLPlus activity working I noticed that I can just drop the stored procedures into the flow as a
"Transform activity". I linked everything up but as soon as I put the "Transform activity" in the process flow it failes with
a complete failure. The OWB Browser gives NO details. It just says complete failure. The stored procedure aka. "Transform activity" validates fine
and executes fine when I do it manually via the DB console.
Any ideas?

Hi MccM,
The OWB browser tells me that the sql load worked and the procedure did not. (I am not familiar with audit views but I doubt that the problem is on the database side since the stored procedure complies fine from there). I noticed that I can configure the activity and set the execution environment with is "NATIVE" in my case. - I dont have any options there.
Here is a [screen print|http://www.metallon.org/test/e34.jpg] of the OWB browser.
This is urgend now so I would be very happy for any help and generously give out the "Helpful" post points :)

Data Type for Process Flow... PB with Date?

I've got a problem by passing parameters in process flow.
I have a mapping with a parameter DATE_EXEC (data type : DATE) and a default value that is TO_DATE('20/01/2007' , 'dd/mm/yyyy') . My mapping is working good when i launch it.
I have a process flow which contains the mapping. This process has a parameter DATE_EXEC (data type : DATE). I bind the 2 DATE_EXEC. But when i launch my mapping the value is not recognized, I try with :
- TO_DATE('20/01/2007' , 'dd/mm/yyyy')
- 20/01/2007
- 2007.01.20
- 2007-01-20
My question is what are the data type in process flow? They are not ORACLE TYPE.
For example , a parameter in a mapping which is a VARCHAR2 must be input between quotes but if you bind it to a parameter of a process flow which is a STRING (not ORACLE Data type) , you must input it without quotes?
Anybody has some rules about that?
I apologize for my english, i'm a french people.

Here is some information on the literal quote or not quote query and what I think you need to do at the end, hope it helps. Not exactly intuitive...since the flow designer (you) have to know what is a PLSQL object and what is not.
1. Literal = FALSE
When Literal = FALSE is set then the value entered must be a valid PL/SQL expression which is evaluated at the Control Center e.g.
'Hello World!'
22 / 7
2. Literal = TRUE
When Literal = TRUE then the value is dependent on the the type of Activity. If the activity is a PL/SQL object i.e. Mapping or Transformation, then the value is PL/SQL snippet. The critical difference here is that the value is macro substituted into the call for the object. The format of the value is identical to that entered as default value in the Mapping editor. e.g.
'Hello World!'
sysdate()
If the activity type is not a PL/SQL object then the value is language independent. e.g.
Hello World
3.1427571
What you should try......
Check the map activity parameter in your process flow to see if literal is false (an expression), set it to false and then try using your TO_DATE('20/01/2007' , 'dd/mm/yyyy') expression, deploy your flow and execute. Alternatively the user guide defines the DATE type for flow with the format YYYY-MM-DD so you can have the parameter value as '2007-01-20' use literal equal to true and remember and quote your value.
Cheers

OWB11gR2: Mapping execution in a process flow not visible in OWB Browser

When a mapping is executed inside a process flow, execution details are not visible in OWB Repository Browser (Control Center reports) - rows processed, errors etc. Mapping row is missing in a log, like it never happened (but it did).
This auditing information is very important for monitoring reasons (to our customers also) and I just don't get it how this functionality is lost with this version. Another serious bug?

Hi David,
I was rather tired and frustrated last evening, so today I noticed some things I didn't yesterday. Your reply gave me a new motivation.
The conclusion is - a mapping execution in a process flow is logged, but the way activities are displayed in OWB Browser are now different than in previous versions. If I click on 'Execution Job Report' on a process flow, I see all the activities listed except mappings (transformations, assign, file exists, subprocess etc.). If I want to see mapping execution row, I must click on a plus (expand) sign.
This kind of behavior will make processes with a complex hierarchy (usually we have more than 5 levels of subprocesses) rather vast to monitor. In 10gR2, a drilling down was accomplished by opening a new browser tab (Execution Job Report link) for each subprocess/mapping activity. Now it shall remain on one huge screen (list) that keeps expanding.
But, if that is the new feature, we shall live with that. If our customers won't like it, they will have to get used to it.
Thank you for your reply!

Regarding Performance Tunning of Mapping & Process Flow

Hi,
i have around 60-70 GB data in Target database.
i need do improve the performance of Mapping and Process flow.
i have used lookup transformation in mapping.
Plz give me some tips for improving performance of Process.
Thanks,

Please go through a Performance Tuning Book for Oracle 10gR2.
Most importantly remember that in Oracle 10g, your performace of mappings can be increased manifold by following these steps:
1. Do not design a mapping wherein you load a table and then select from that table to load another table and so on. This is a bad design.
2. Keep mappings as simple as possible. In other words if a mapping is complicated in terms of joins or other operators then split the mapping into more than one parts.
3. Also check that all your source tables should be analyzed using DBMS_STATS. Ensuring this one single step can make your work very easy.
4. Put indexes where you find your predicate has a very high selectivity. Also keep in mind the column ordering of the index.
5. Use Set Based operation, since it is always a good idea to achieve the result by running one single query rather than a loop and multiple inserts.
6. Use APPEND PARALLEL hint while loading the target tables. This will not generate wny redo and save time
7. Please have a recheck while usng some performance intensive operators like UNION, DISTINCT and AGGREGATION
8. When using a sequence operator to load a large table, check that the sequence should be cached with some values.
9. When loading large data HASH JOINS are the most appropriate more often than not. So you can use USE_HASH as the hint for selecting from large tables.
10. Filter out as much unrequired data from a table as soon as possible in the mapping before doing multiple joins.
I am sure there are many more ... the above is just a random list that I could remember now. Please go through Oracle Performance Tuning Guide, Tom Kyte's Oracle Expert One on One. Knowledge of performance tuning will grow with experience. I am also learning each day !!!

Audit_id of a process flow

OK, i know this is basic, but I am new to OWB. How do I get the audit_id of a process flow at execution time? I am running OWB 10.2.0.1. The Transformation Guide as well as the User's Guide says that "you can obtain the audit ID at execution time using the pseudo variable audit_id" when using the Control Center Transformations, but all of their examples use hardcoded audit_id's. There doesn't seem to be any other mention of "pseudo variable" in any of the other OWB documentation.
thanks in advance

Hi
See the global expression values below, you can use PARENT_AUDIT_ID to get the calling process flows audit id:

OWB Process Flow Execution in Workflow

Hi!
I hope somebody can help me with this one... I have a process flow designed to load data from a flat file to a db staging table then do some transformation on the data and load the data to the data warehouse. I am using OWB 9.2.0.2.8, 9i DB (9.2.0.5) and OWF 2.6.2. I have successfully validated and deployed the process flow but during execution, the process failed on the mapping that loads data from the flat file to the staging table. The message log of the deployment manager reports: /u01/oracle/product/owb/temp/STAGING_MAP.ctl (No such file or directory). Do I have to set the source location for the flat file again? You see we have already executed this mapping alone and it worked fine, using the source location in the server as defined in the mapping, which is /u01/files/.
Thank you.

hi,
well,jus check whether u created locations and connecter and check u deployed every thing and try once again.

Date parameter in a process flow

Hi,
I´m working with OWB 10.1.0.2.0.
I have a process flow with a transform.
The transform has a date parameter and I´ve defined a date parameter in the start activity, which is bound to the start parameter.
If I try to pass a date parameter in this form, sysdate, the process doesn´t recognize it and in the all_rt_audit_execution_params table i can see that the param process has no value.
If I pass a date parameter in this format 2006/08/07 the process works fine
I need to pass the date parameter from start activity to the process activity using expresions with sysdate,
may anyone help me? please and thanks
beatriz

Hi,
there are several tasks you want to accomplish:
1. "I need to check if the parameter file exists"
Therefor OWB has the File Exists Activity (Process Flow). This one checks if a file exists with specified name on specified location. If so it returns with SUCCESS. If not, it returns a WARNING. In second case you should do a sleep for a while and then re-check.
2. "accessing the date value from the parameter file"
There will be several ways to do this. The easiest one may be, to declare a external Table on this file and simply select from it (use it as a source in your mapping)
3. "After the ETL is finished running, the name of the parameter file needs to be changed"
In your process flow you create a user defined activity. In this one you start cmd.exe (on windows) and execute any DOS-commands you like. In this case a move or rename.
Hope I could help you...
Bye,
iOn.

Find out type of activity in process flow

I am currently working on generating process flows. I place a bunch of mappings or sub process flows (sometimes more than 20) in a process flow. Then I connect them basically to indicate the order in which they have to be processed.
Next I want to generate the succes, warning and error transitions. I can easily list the activities in the process flow using
OMBRETRIEVE PROCESS_FLOW 'SOME_FLOW' GET ACTIVITIES
likewise I can easily retrieve the transitions.
My main problem now is that I cannot find where to start.
I know a process flow is created default with a START1 activity but the name can be changed, so that is not a fool proof option. I have been looking for something like
OMBRETRIEVE PROCESS_FLOW 'SOME_FLOW' ACTIVITY 'START1' GET PROPERTIES (ACTIVITY_TYPE)
But the property apparently does not exist.
If I do
OMBDESCRIBE CLASS_DEFINITION 'PROCESS_FLOW' GET CHILD_TYPES
I see a START_ACTIVITY child type is listed. Now I am looking for a way to connect the child type to the activity
Anybody ideas?
Thanks in advance,
Kind regards,
Eric.

Thanks Oleg,
After posting the question on the forum I remembered I had made lists of activities for various activity types, in my case MAPPINGS and SUBPROCESSES. So I tried the same for START activities, just like you apparently have done. And with the same conclusion; there is not a complete list of activity types you can use.
I also noticed there is no START activity in the Palette of the Process Flow editor. And that you cannot delete a start activity (API-10011 You cannot delete this type of activity). Apparently a start activity is a special case of activity. And I think I will treat it this way. I will assume no one in his right mind will rename this activity from it's default 'START1' name and start my exploration of the flow in the process there.
Thanks again for confirming my suspicions.
In the process of finding out activity types that are supported I made a list (OWB 10.2.0.3):
OMBRETRIEVE PROCESS_FLOW 'EERSTE' GET AND ACTIVITIES
OMBRETRIEVE PROCESS_FLOW 'EERSTE' GET ASSIGN ACTIVITIES
OMBRETRIEVE PROCESS_FLOW 'EERSTE' GET DATA_AUDITOR ACTIVITIES
OMBRETRIEVE PROCESS_FLOW 'EERSTE' GET EMAIL ACTIVITIES
OMBRETRIEVE PROCESS_FLOW 'EERSTE' GET END_ERROR ACTIVITIES
OMBRETRIEVE PROCESS_FLOW 'EERSTE' GET END_LOOP ACTIVITIES
OMBRETRIEVE PROCESS_FLOW 'EERSTE' GET END_SUCCESS ACTIVITIES
OMBRETRIEVE PROCESS_FLOW 'EERSTE' GET END_WARNING ACTIVITIES
OMBRETRIEVE PROCESS_FLOW 'EERSTE' GET FILE_EXISTS ACTIVITIES
OMBRETRIEVE PROCESS_FLOW 'EERSTE' GET FOR_LOOP ACTIVITIES
OMBRETRIEVE PROCESS_FLOW 'EERSTE' GET FORK ACTIVITIES
OMBRETRIEVE PROCESS_FLOW 'EERSTE' GET FTP ACTIVITIES
OMBRETRIEVE PROCESS_FLOW 'EERSTE' GET MANUAL ACTIVITIES
OMBRETRIEVE PROCESS_FLOW 'EERSTE' GET MAPPING ACTIVITIES
OMBRETRIEVE PROCESS_FLOW 'EERSTE' GET NOTIFICATION ACTIVITIES
OMBRETRIEVE PROCESS_FLOW 'EERSTE' GET OR ACTIVITIES
OMBRETRIEVE PROCESS_FLOW 'EERSTE' GET ROUTE ACTIVITIES
OMBRETRIEVE PROCESS_FLOW 'EERSTE' GET SET_STATUS ACTIVITIES
OMBRETRIEVE PROCESS_FLOW 'EERSTE' GET SQLPLUS ACTIVITIES
OMBRETRIEVE PROCESS_FLOW 'EERSTE' GET SUBPROCESS ACTIVITIES
OMBRETRIEVE PROCESS_FLOW 'EERSTE' GET TRANSFORMATION ACTIVITIES
OMBRETRIEVE PROCESS_FLOW 'EERSTE' GET USER_DEFINED ACTIVITIES
OMBRETRIEVE PROCESS_FLOW 'EERSTE' GET WAIT ACTIVITIES
OMBRETRIEVE PROCESS_FLOW 'EERSTE' GET WHILE_LOOP ACTIVITIES
Kind regards,
Eric.

How to run procedure in Process flow

Hello,
I have a small procedure which I want to run in between two different mappings. I want to achieve it in process flow.
I had understanding that this can be done using transformation but didn't had much success.
Please suggest.
Thanks

You are correct that this is done with a transformation in the process flow, and this is the way to do it.
What kind of error message did you get?
Was it something with the deployed location for the transformation not being set?
If thats the case, in the design center, mark the process flow and right click, then choose configure. Find the transformation and set the location for where the procedure is deployed.

Function in a Process Flow

Hi all,
I have a function which returns a value either 1 or 0. I want to get the output of the function and check if the function returns 1 then the process flow should be successful else it should error out.
I have created a simple process flow, which has start, function, success and error. From the function to success transtion i have given an complex condition where value =1 and the other transtion should be kept empty. But it didnt work.
Any ideas how exactly we can use a function in a process flow.
Thanks in advance

There is another way of achiving it....
Go to process flow -> Configure and click on the function operator.
Under Execution Settings, select the option Use Return as Status
This setting governs the behavior for activities that return NUMBER in their output. These activities include the FTP, User Defined, and Transform activities. When you select Use Return as Status, the Process Flow Editor assigns the outgoing transition conditions based on the following numerical return values for the activity:
1 = Success Transition
2 = Warning Transition
3 = Error Transition
You might have your function return 1 for success and 3 for error and the transition would take them as status code.
Thanks,
Suchit
