Mapping sequence in a flow

Hi,
I want to know the execution plan in the process flow.I mean,Is there a table or view that shows the connection information of a mapping in the flow.?.
Which maps must run before a map?.
Thanx.

Well,
yes, but.
in the previous version this is in the owf_mgr tables. But these tables are not meant to be looked at by users. If have not worked with the paris release yet. But it has something comparebale.
Just browse the tables to find the ones you need, decode the meaning and build a view to have your info in a comprehensable way.
You need at least WF_ACTIVITIES and WF_ACTIVITY_TRANSITIONS and one or two others. But don't let your dba know where you are looking. ;-)

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.

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

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.
Thanks

Sequence in process flow (output from mapping)

I have a mapping where I am using sequence operator and creating a record in the target table I need to pass this variable out of the mapping and as input to another mapping. I am not able to pass the sequence out of the mapping. How can we assign values to mapping output variables however I do it it says you cannot assign variables to output parameters from the mapping it says.
mapping input parameter and mapping output parameter are intended to be executed before and after the data flow of the mapping and cannopt accept inputs from any part of the data flow.
Any ideas as to how this can be done.
Can a pluggable mapping be called in a process flow.
Thanks
Edited by: user8023060 on Jun 23, 2009 6:08 AM

Hi,
write a plsql-function that executes returns seq_XXX.currval (or, to be on the safe side, select the value from your table).
Assign that value to an output attribute.
And no, pluggable mappings can just be included from other mappings, there is no way to execute them directly.

Carsten.

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);

Skipping mapping execution in process flow

I have a process flow that calls multiple mappings. Based on some condition I want a mapping not to execute, E.g. when rerunning the process flow in case of failure. Currently I keep track of mapping execution and store the status in a control table. When a mapping has completed, it updates the status as completed. When I need to rerun, in the SQL of the tables join in the mapping, I have a where clause that returns 0 rows (mapping_completed = N) . So mapping is excuted but no rows added/updated.
The flip side of the approach is when using a complex join specially using views, the SQL takes a long time to run only to return 0 rows. So logic is okay but I want to save time by avoiding the execution of the mapping it self.
I would like to know how others are implementing this scenario.
Regards
Sandeep

Can you not have two different mappings one for running it first time and one which you can run on failure...
In your process flow you can have a param i.e 'F for failure and 'I' for intial and based on this condition you can decide which mapping to invoke and hte path to be followed.

Can not delete a parameter of a mapping in a process flow

Hi,
I want to delete a certain input parameter of all mappings in a flow with tcl.
I use this:
OMBALTER PROCESS_FLOW '$flow' DELETE PARAMETER 'IP_VERSION' OF ACTIVITY '$act'
If i test this in the OMBPlus window it says it deleted it however it is still there i the flow.
If i use this statement in a tcl script the script halts without message.
It says :
Process Flow Parameter IP_VERSION deleted.
process Flow PFP_MIKE_1 altered.
And when i retrieve the parameters afterwards it is indeed stil listed:
OMBRETRIEVE PROCESS_FLOW '$flow' ACTIVITY '$act' GET PARAMETERS.
Can somebody confirm:
--that i am using the proper syntax
--if this is a known bug in owb 10gr2 10.2.0.1.31

Edited by: MichaelR64 on 7-jun-2013 9:46

Nobody ?
I did some more testing.
The clause i am using is this: deleteGenericActivityParameterClause
deleteGenericActivityParameterClause = PARAMETER "QUOTED_STRING" OF ACTIVITY "QUOTED_STRING"
See here: http://docs.oracle.com/html/E14406_01/chap4003.htm for the 11g verrsion.
My flow has calls to other mappings in it.
Both the mappings and the flow itself have this input parameter IP_VERSION.
It seems the OMBplus parser is making an error.
When i specify the name of the input param that is of the flow(and not the mapping in the flow) , but the rest of the command specifies the mapping activity as in OP, then OMB says that it deleted the parameter and that it altered the flow.
And it halts there.
But when i check the actual flow nothing has changed.
When i specify the name of parameter that the called mapping has , ofcourse with the full command line as in OP, then OMBplus says it can not find the specified parameter.
So it seems that the parser makes two errors:
When searching for the parameter it looks in the wrong place, it always looks in the flow section instead of the acitvy specified.
The ' OF ACTIVITY '$act' ' part is not used it seems.
The delete part of the instruction is also confused by this and says it deleted the parameter but nothing actually happens.
Hope somebody can confirm/shed more light on this.

Losing source-target mapping from a data flow diagram process

Hi,
When I reload a model design from an xml repository, I am losing source-target mappings from a data flow diagram process. I wonder why.
The way it goes is:
- I define a data flow diagram with information stores, processes, and flows.
- Information structures are defined from the flows and the information trickles down to processes and information stores.
- In a process, I define Source-Target Mapping by selecting a target element and then selecting the source element(s).
- I save the whole model.
- So far, the Source-Target Mapping keeps the association between target and source elements.
- If I exit from Data Modeler, the next time I reload the saved model, the Source-Target Mapping target to source elements associations are lost!?
Does anyone have the same issue or would know how to resolve it?
Thanks,
/Mario

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 tace erronious records in a mapping or a process flow?

Hi All,
I read the following document by Rittman.
http://www.rittman.net/work_stuff/tracing_owb_mappings_pt1.htm
I am using Oracle Warehouse Builder 10G R1.
But I feel, it may solve my problem. My problem scenario is as follows.
Here I would like to know how to trace the records which are valid as per business rules, but not counted in the output due to some functional errors, as follows.
For example a variable contains value Region = "R01".
So as per the rule, we need to retrieve the number 01.
I impelemented as to_number ( substr (Region,2 ) )
Unfortunately, In one record, I got the field data as "RRR".
So as per the rule , if apply that logic, this will return the error/warning.
So this record is not counted in the output.
Here I would like to trace these type of records in a table or a file while executing the Mapping.
Is it possible using Oracle Warehouse Builder or Oracle?
When we are dealing external table we can create log or bad file, which will hold all bad records by default. Is there any way to do this in a mapping?
Is any one implemented these kind of tracing files which contains all bad records.
Any suggestions are welcome.
Thank you,
Regards,
Gowtham Sen.

Hi,
i have never used this before but i know that inside the mapping configuration in the table operators there is a property where you can specify in the constraints management the exceptions table name. Anyway you might add an additional field to your target table, add a case expression and then mark the field as being valid or invalid or something like that. You can then select the which records are invalid.
Take a look at this thread: Some Thoughts On An OWB Performance/Testing Framework

Owb beta 3 / master detail mapping with sequence ora-00936 error

I'm not able to use sequence operator in mapping to create relationships between different record type from the same flat file. I have got an sql error ORA-00936: expression absente
The problem seem to be the sequence is not referenced in the sql loader parameter. The sequence exists, was deployed sucessfully, the mapping is validated and successfully deployed. The problem occurs during execution

Good afternoon "micwic",
In general, mappings with flat files make use of data generators, not sequence operators. This is what the User Guide (10gR1 but I guess R2 works similar) says for the Data Generator Operator :
Use a Data Generator operator to provide information such as record number, system date, and sequence values.
For mappings with flat file sources, the Data Generator operator also provides a place to enter constant information. For mappings with Flat File sources and targets, the Data Generator operator connects the mapping to SQL*Loader to generate the data stored in the database record.
The following functions are available:
RECNUM
SYSDATE
SEQUENCE
It is possible for Warehouse Builder to generate data by specifying only sequences, record numbers, system dates, and constants as field specifications. SQL*Loader inserts as many records as are specified by the LOAD keyword.
Setting a Column to the Data File Record Number
Use the RECNUM keyword to set an attribute to the number of the records that tthe record was loaded from. Records are counted sequentially from the beginning of the first data file, starting with record 1. RECNUM increments as each logical record is assembled. It increments for records that are discarded, skipped, rejected, or loaded.
For example, if you use the option SKIP=10, the first record loaded has a RECNUM of 11.
Setting a Column to the Current Date
A column specified with SYSDATE gets the current system date, as defined by the SQL language SYSDATE function.
The target column must be of type CHAR or DATE. If the column is of type CHAR, then the date is loaded in the format dd-mon-yy. After the load, you only access it in that format. If the system date is loaded into a DATE column, then you can only access it in a variety of formats including the time and the date. A new system date/time is used for each array of records inserted in a conventional path load and for each block of records loaded during a direct path load.
Setting a Column to a Unique Sequence Number
The SEQUENCE keyword ensures a unique value for a column. SEQUENCE increments for each record that is loaded or rejected. It does not increment for records that are discarded or skipped.
Recommendation: For PL/SQL mappings use a Constant Operator or Mapping Sequence Operator instead of a Data Generator.
etc.
Good luck, Patrick

Wrong map being executed in Process Flow

I created a Process Flow that executes 3 maps and a PL/SQL procedure.
The process flow functions to write data to a Unix file system.
The first map when executed by itself writes the correct string as the first header within the file. But when I execute the same map, named HC_ENTHDR_TEMP_MAP, within the Process Flow the wrong header is written to the file.
I've tried droppping the map and redeploying it. I've tried dropping the map within the Process Flow reinserting it and redeploying the Process Flow. These actions do not solve the problem. When the map is executed within the Process Flow, the wrong header is written. When the map is executed outside the process flow the correct header is written.
Any help would be appreciated. It's as if the WorkFlow schema has the an invalid pointer to a map that I can't get rid of.

Hi,
Sorry for the late reply, but I was off for the Holidays. Anyway.
I have tested your scenario step by step. and it works just the way you're saying.
But, what's happening here is just as Steve have mentioned in his second post.
<quote>All the codes are in the same "bucket"</quote>
And as I mentioned in my first post the local unit precedes the library, and that's why you are seeing the message from the local unit.
I changed the name of the local unit from MY_PRE_FROM to MY_PRE_FORM_LOCAL, and it worked just fine with me.
I suggest you try it, it should work.
So when we run formA we should see the following messages
'in generic call'
'in formA local'
Here what you are seeing the the precedences of the local unit over the library unit whenever they share the same name.
but logically you should see the library code MY_GENERIC_CALL being executed and showing a message of
PROCEDURE MY_GENERIC_CALL IS
BEGIN
message('in generic call');
my_pre_form;
END;and in turn calling to MY_PRE_FORM and the latter shows the message
PROCEDURE my_pre_form IS
BEGIN
message('in lib my pre-form');
END;so you should see:
in generic call
in lib my pre-form
and what's happening with you is the local unit is being preceded from forma over the library unit. As if you are calling the local unit from the library. or at least this is what seems to be happening.
Changing the local unit's name is making the difference.

Tony Garabedian
