OWB mapping

Hi,
I am new to OWB.My project is OWB 11G Rel. 2 for ORACLE 10G REL. 2
I have go through doc but i m not able to understand cencept behind mapping.
Can anyone help me for how to define mapping and purpose of manning?
HOw it effects database performace?thanks
Shital Patel

Hi Shital,
Mapping is the process defined to transfer data from source system to target system.
You can do various operation while transferring these data like filter out some data , join multiple source set , looking up to a reference and so on.
OWB generated the pl/sql package per each mapping and it is submitted to ORACLE RDBMS engine to run the same.
So an efficiently designed and developed mapping will have better performance than a non-efficient one .
For more information , refer

Problem in OWB map for source change capture

The problem is as follows:-
Our OWB map between two different databases, captures change in data at source and populates them in target. It is a one to one map. The map is failing to process some rows from source database though it gives no:of errors as 0 in the audit view thus we infer that the map is running successfully.
In our case, we have a composite key ( Instance_id, Version_number) at source as well as target. One instance_id can has more than one version number. We have observed that the view is picking up all the version_number for a particular instance_id but the map is unable to populate the last version_number to the target table.
But when this map was executed in another environment and it is successfully populating all the data in the target.
The brief description of the map is as follows:-
The map has a view which captures all the changes in data (insert and update) .From this view we filter the rows which were already processed in previous map run (with help of watermark). Then we sort the rows based on DML type and watermark . These rows are then mapped to a target table. The loading type of the map is INSERT/UPDATE.

Hi Nagesh,
When we are doing I18N for that Application. Go to Navigator Tab

Case statement in OWB mapping

I am trying to use a case statement in an OWB mapping. I am attempting to use it in expression builder within a filter object. Each time I try to validate the expression in the expression builder I get an error:
Line 4, Col 6:
PL/SQL: ORA-00920: invalid relational operator
Below is the code used in the expression builder window:
CASE A.ATTRIBUTE_NAME
WHEN 'CA COMPLETION DATE' THEN RTRIM(A.C_CODE_VALUE)
ELSE NULL
END
Any help with what is happening would be appreciated.
Thank you.
Matt

Thank you both for you help. I initially tried to use the expression operator but was confused since the expression builder in the expression operator has the drop down list with the available SQL clauses greyed out. In the OWB documentation it states that the drop down will contain SQL clauses that are appropriate for that expression type so when I saw it was greyed out I assumed that those clauses where not valid for this operator. Sure enough though when I pasted in my Case statement it verified correctly.
Thanks again,
Matt

Array of Parameters in OWB mapping

How do i pass an array of parameters to an OWB mapping.

Try this and similarly you can get all operator.
OMBRETRIEVE MAPPING 'MAP_NAME' GET TABLE OPERATORS
OMBRETRIEVE MAPPING 'MAP_NAME' GET VIEW OPERATORS
OMBRETRIEVE MAPPING 'MAP_NAME' GET TRANSFORMATION OPERATORS
OMBRETRIEVE MAPPING 'MAP_NAME' GET TABLE_FUNCTION OPERATORS

How to Execute a OWB Mapping or a Process from SQLPLUS editor?

I need to know how can we execute a OWB mapping from SQLPLUS editor or from a Stored Procedure.

Hi,
You can use the MDL export/import utility for this, but as you are importing into the same repository you will end up with importing into the same project again.
So for this you can follow the workaround as:
->Take export of the required mapping from the project OWB_B
-> Rename the Project OWB_B to some thing like OWB_B_1(or any other name), note that you have to rename both logical and physical name of the project
-> Rename the project OWB_A to OWB_B and if you import the MDL all the objects will be imported to OWB_B then you can rename back the project to OWB_A
-> Finally rename the project OWB_B_1 to OWB_B (to its original name).

Transformations not occuring properly using PIVOT operator in OWB mapping.

Hi ,
In our project we have a OWB Map UII_D_MAP_SPC_CUST_FAULT_NATTR which is used to populate UII_CUSTOMER_FAULT table in our target side.
The source table which populate UII_CUSTOMER_FAULT is SR_S_TABLE_N_ATTRIBUTEVALUE (a materialized view in another External Db)
This Mview has 2 columns: S_N_STRINGVALUE & N_NAME.
When N_NAME is 'FAULT_REPORT_CODE' the corresponding S_N_STRINGVALUE value should populate the REPORT_CODE field in UII_CUSTOMER_FAULTin the target sde.
This source to target transformations is being done by using UNPIVOT operator in this mapping UII_MAP_SPC_CUST_FAULT_NATTR.
In ideal case when S_N_STRINGVALUE is NOT NULL, REPORT_CODE value should be populated with the value of source field value (ie the value of S_N_STRINGVALUE) and when S_N_STRINGVALUE is NULL , REPORT_CODE should be populated with 'XX'.
But in some cases REPORT_CODE value in UII_CUSTOMER_FAULT table is populated as NULL when S_N_STRINGVALUE is NOT NULL
which should not happen.
We suspect that there is some prpblem in the UNPIVOT operator, but we are not able to track down the exact location where it is failing. Can you please help in resolving this problem?
Shall we remove Unpivot operator and use CASE statement in some package that will be called through Expression operator?
Please advise.
Regards
Arinjit Dhar

Arinjit,
Have got any solution forthis. Today I ran into exactly the same problem. If you have got the solution, can you please post it in the forum.
Ott Karesz,
I have posted my SQL which got generated. The problem is when I am running the SQL just for the particular data set, it is giving the output properly. But what confuses me more is, when I run the mapping just for few records, it is populating the values correctly, but when running the mapping for all the records, then it populates null values for those records.

SQL Query of an OWB map (row based)

If I trace a session, execute an OWB map (row based), will the trace file contain the actual SQL query ?
The problem with me is that when I am executing this row -based OWB map, it is throwing me an error CursorFetchMapTerminationRTV20007 BUT ( plus taking a long time) when I am taking out the intermediate SQL insert query,it is working fine ( and also within a very short period of time)
Execution status = COMPLETE
message text = ORA-06502: PL/SQL: numeric or value error: character string buffer too small
message text = CursorFetchMapTerminationRTV20007
No. task errors = 0
No. task warnings = 2
No. errors = 1
Since this OWB map (Truncate Insert) is row based hence I cannot cannot get the back end query from the OWB generated pl/sql package so wondering if I trace the session, check the trace file, may be I will able to see the exact SQL query generated. But wanted to confirm the same.

Yes, the actual SQL run in the session will be in the trace file.

Can not run OWB Mapping automatically by OEM? . Very urgent. Pls help me

Hi all,
Pls help me.
I am using OWB 10g under Oracle 10g. I want to run OWB Mapping automatically by OEM.
I installed Oracle Database 10g fully but don't have OEM in this. After that, I installed Oracle Client 10g. In this product, there is OEM 10g. I read some topic as "want to run owb mappings thru job schedule" and also read http://otn.oracle.com/products/warehouse/htdocs/oem_scheduling_viewlet_swf.html
But my OEM not as same as in this . It don't have job menu and OEM Console Login window and don't have also where I can put username/pwd to login into OMS???
I don't know this problem.
Pls help me.

Hi,
Here are two possible solutions:
1) If you have OEM 9i anywhere in your environment you can use this for scheduling the OWB jobs.
2) If your environment is 10g only you need to install 10g Grid Controll. This product has replaced the OMS / Java console of earlier releases, and contains the same functionality for scheduling jobs.
Note that if you are using the sql_exec_template to execute your mappings you can schedule and run these from any machine on the network, not just the target server.
Hope this helps,
Roald

How to track OWB mapping changes?

Hi,
I'm a new bee to OWB. And I have a scenario where in more than one person will work on the same mapping. so I dont see any way to track the changes made by others. Is there a way to track who updated the OWB mapping last time and the changes they have done on the mapping??
Any help is Appreciated.
Thanks!!

I don't think there is a good way to track details for changes. There is a snapshot feature, but I don't think you can see what the specific modifications were. I don't use it. I use periodic mdl backups in case I need to recover the design (fortunately never had to do it) or to move updated objects across (when needed I track which objects changed in a spreadsheet). I also use a fairly primitve way of tracking my changes by storing prior versions of mappings (not all). If I want to keep a prior version, I copy the mapping and add '_V#' at the end. This indicates my last prior version. Then if I want to create another copy I will rename the current '_V#' to '_V1' (i.e. '_Vn'). Next I will create a copy of the current mapping and add the '_V#' at the end. Nothing sophisticated, but I use this sometimes and cleanup as things progress.
If there is a way to track and see all detail changes I would love to hear about it also.
Thanks!

Row movement Disabled at DB- creating problems in OWB mapping

Hi All,
We have a OWB mapping 'XXXXX' with Default operating mode set to 'setbased-failover to rowbased' mode.The generation mode is set to 'Row Based'.This is called in a processFlow 'YYY'
This was running fine until sometime ago.
Recently at the database row movement on tables was disabled.
After this the 'YYYY' fails with a 'Warning:ORA-01403: no data found' when it calls 'XXXXX'.
Any idea on what this means.Is it something to do with the row movement disablin done recently?
Is the default operating mode and generation mode combination selected by us valid.
Please provide any inputs /queries by which we can trace the exact problem.
Many Thanks!!
BRgds
Sridha

I don't think that issue will be with OWB.
take generated code and run in directly in database and check are you getting the same error.

How to use OMB to change filter conditions in OWB maps

Hi,
I want to know how we can use OMB to change filter conditions in an OWB map.
As per my scenario i have a filter operator FLTR_1 in my maps and i have to change its filter condition from
INOUTGRP1.ID IN (1,2)
AND
INOUTGRP1.VALUE > CONST_0_MAX_VAL
to
INOUTGRP1.ID IN (1,2)
AND
INOUTGRP1.VALUE > CONST_6_MAX_VAL
Just for everybody's information we are migrating from OWB 9.2 to OWB 10.2 and we have called procedures in constants and used their values in filter conditions.OWB 10.2 generates the values for constants in a different way than OWB 9.2 thats why this change is required.I wish to automate the act of changing constant names so we can save time in changing the maps.
Thx

Carsten,
I created a map in OWB 10.2 and ran the following command
The filter operator name in this map is FILTER
Carsten Herbe wrote:
OMBALTER MAPPING 'TEST_MAP' MODIFY OPEARTOR 'FILTER' SET PROPERTIES (FILTER_CONDITION) VALUES ('INOUTGRP1.ID IN (1,2) AND INOUTGRP1.VALUE > CONST_6_MAX_VAL ')
I got this error:

Problem in running OWB maps

Hi ,
We use DBMS to kick our OWB maps.Previously it worked very fine ..But from near about 2 weeks we are facing problems.
Problem is though our JOB_QUEUE_PROCESS is set to 8 and even I can see 8 jobs with this_data populated in dba_jobs (means jobs are running as we cannot query DBA_JOBS_RUNNING view to see the no of jobs running as it is taking too much time ) we can see only entry of two of there maps in WB_RT_AUDIT.other maps start only if these two get complete .
and there is huge time difference between actual job start time and the entry into WB_RT_AUDIT table .
can any one help us with solution.
Bcos of this issues load which used to take max 4 hours is now taking 24 hours..
Thanks & Regards

I've successfully installed OWF as described in Installation guide (all components are on the sam server).
But when I deploy a workflow in OWB I get some errors. In the job details
I find ORA-00942 and RPE-02053. It seems that the workflow repository is missing.
Are there additional steps for creating a workflow repository?
Or what is wrong? All installation logs (wf.log and workflow.log) are without errors and with success messages.
Any idea?

Owb mapping result in excel sheet

hi ,
can anyone help me to know how i can get owb mapping running status & result in excel sheet.
I have completely forget it.
kindly help.
rgds,
pc

Hi,
You can view the status by qurying wb_rt_audit_map_runs from any SQL client.
From there your can copy the output to excel.
Otherwise you can use OWB repository browser to view the mapping running status report.

Regarding default select clauses executing during OWB Mapping execution -

All-
While observing the statements executing during an OWB(11gR2) Mapping execution,by monitoring the session using SQL Developer
Iam finding the following statements executing multiple times and possibly consuming more of the mapping execution time:-
SELECT MAX(EXECUTION_AUDIT_ID) FROM ALL_RT_AUDIT_MAP_RUNS WHERE MAP_NAME = :B1
SELECT SYS_CONTEXT('owb_workspace' , 'workspaceID' ) FROM DUAL
SELECT nvl2(translate(20040101, 'A1234567890','A'), 'F', 'T') FROM DUAL
SELECT USER FROM SYS.DUAL
These statements have no relation to be business logic being implemented.And seem to be generated by OWB default settings.
Can anyone please let me know how to reduce the frequencey of the above mentioned statements or if possible remove them from the OWB mapping execution.
So that the mapping would run more faster

Hi,
these statement are required to set the runtime audit data. Usually, they do not really impact the performance of a mapping so there is not need to bother about them.
What causes performance problems is usually the business logic part of the mappings.
You may purge old runtime metadata manually. Look at the script
%ORACLE_HOME%\owb\rtp\jrtaudit\owbsys\purge_audit_tables.sqlDocumentation is included.

Carsten.

Configuration parameters in OWB mapping

Hi ,
I have a requrement where in I need to find out some details of an OWB mapping through a SQL script.
For a mapping when we "configure" the Table operators like entering the Schema name. Which table in OWBRT_SYS holds these details basically I need to query the OWBRT_SYS.TABLE_XXXXX to find out for a given mapping weather the Schema name has been entered or not.
Please suggest.
Thanks,
Jay

Re your first question, you are probably hitting a bug (3035080) that makes OWB generate false warnings. Please ignore the warnings and try to deploy and run the process flow.
As for your second question - I cannot reproduce this on 9.2.0.2.8. The configuration properties are updated corectly in the SQLLOADER map and I get the same values in the process flow. By the way, why are you not using external tables instead of the SQLLoader maps?
