Creating SQLSERVER source module in OWB 10gR2

I need to import the data from Sqlserver2005.
For that I followed the steps:
1. Crated the System DSN.
2. Modified the tnsnames.ora,listner.ora.
3. Add a file like 'inithsodbc.ora' in /hs/admin
4. Listner started at server machine.
5. Created a database link at sqlplus.
6. when i select any table from sqlserver at sqlplus,
I got the error as:
ORA-12154: TNS:could not resolve the connect identifier specified

Error creating a new module in OWB

Hi All,
I am getting an error while creating a new module using OWB. We are using 11.2. Any Inputs are greatly appreciated. Has any body experienced this problem.
The error is as follows..

I think there are some connectors that point to locations that do not exist any more. If you expand the locations in the location navigator and check the connectors under the location in the tree, there will be some that are no longer valid.

Create Data Source Module using OMB

I am not seeing how to create Data Source modules using OMB. I am assuming there is a property of OMBCREATE ORACLE_MODULE that I am overlooking. If anyone can provide assistance, it would be greatly appreciated.
Thanks,
craig

Hi,
Yes, there is a OMBCREATE command for creating Oracle Modules. And as per the Scripting ref Guide ( Page 4-157 owb 9i scripting guide) -
OMBCREATE ORACLE_MODULE 'src_module' SET PROPERTIES (DESCRIPTION, BUSINESS_NAME) VALUES ('this is an Oracle module', 'source module') This will create an Oracle module named "src_module", its description is "this is an Oracle module", and business name is "source module".

How to create MSSQLserver source module?

hi, all
My source database is MS SQLServer2000,
how do I create SQLServer2000's source module?
I need particular process ã thank you!

Hi JP ,
Yes. I have already imported the tables into the OWB repository.
Anyway , I can deploy the mapping successfully !!! I checked a topic in this forum which is
Re: For MS Access
Nikolai Rochnik said
"However, when you register a location, the Schema value will be used by OWB to construct a schema.table@db_link in a FROM clause. You want it to be just table@db_link but OWB does allow for empty value in Schema. I will log this as a bug, but an easy workaround would be to use db_link explicitly in the mapping configuration, thus disregarding registered location. Right-click on your map -> Configure -> Source and Targets -> [your source table]. In the Database Link paste the name of the link that was created by OWB in the target schema when the Connector was deployed. It would be something like, depending on your naming, ACCESS_SID@FROM_ACCESS_TO_ORCL.
I have just tried it and it generates, deploys and executes correctly."
I followed his steps and get it work but there is a warning message.
LD-1124: Schema and/or Database link physical configuration parameters should not be set for Table1.
Is it possible to eliminate this warning message ? Anyway , Thanks for your response and help !

Problem with Creation of Source module for MS Access

I am having a problem in creating a source module connected with an "MS Access" file in OWB 9i using the heterogeneous services. I have created a DSN to an access file (.mdb) and created the HS in Oracle (modified the tsnames.ora and listener.ora files with required details). Created a Database link using this service and it's working fine in SQL PLUS, but I am unable to create a Source module in OWB 9i using this db link, since OWB 9i need a schema name for db link. In MS access it's not possible to have a schema.
Please help me in solving the above issue.
Thanks in advance
Jagan

What version of OWB and Oracle database are you using? If it is an OWB version 9.0.4 or higher, I presume you are trying to create a non Oracle source module under the Oracle Database node - is this the case? If yes, you should not do that, but create your MS Access module under Databases->Other->Other node (as I understand you are not using ODBC). Let me know if my assumptions are correct.

How to change the source module version

Hi All,
In the OWB i created a source module and during those steps i clicked on version 10.1, but during deployment in the deployment managaer when i tried to register the location, its giving me an error as "Source verison 10.1 is not matching with the target version 10.2", can any one please help me or Advice me as to how to change the "source module version"?
Thanks

Hi
what i understood is that the source module is associate with the location and you have provided the 10.1 which you need to change.
so you can change that under location.
Cheers

How to delete connections for modules in OWB?

Hi all,
When we create an Oracle Module in OWB, we can create and specify a connection for the module. But I don't know how to delete or modify those connections. Anyone can tell me a method. Thanks a lot.

Hi Nikolai Rochnik,
Thank u. But I think u misunderstood me. I'm not refering to OWB Module locations. Instead, I'm referring to Module Connections. That is:
/Databases/Oracle/<Module>/Properties/Connection.
When u enter the screen, u can find the "new DB Link..." button. Now I know that the connections are in fact db links in the design time repository db. So we can modify them using SQL.

Is it possible for buyer to create both RFQ and supplier response (i.e. quotations) in Sourcing module?

Hi,
In Vision Demo, after buyer (e.g. cbaker) creates a RFQ, then i can logon as supplier account (e.g. 'industrial') to input corresponding quotation.
But as our site doesn't allow suppliers to logon our EBS directly and we receive paper quotations, then, is it possible for buyer to input quotation for these RFQs in Sourcing module?
Thanks
Leo

private String createTransmitter() {
localAddr = new SessionAddress( InetAddress.getLocalHost(), port);
destAddr = new SessionAddress( ipAddr, port);You can do instead:
localAddr = new SessionAddress( InetAddress.getLocalHost(), SessionAddress.ANY_PORT);

Are sas db source modules available in owb

I am using OWB 10.1.0.2 and I would like to use SAS as a source module, is there a gateway or plugin for owb that I can use.

I'm not sure. I know there is some way to connect between the two, but do not know details. I suspect a search on something like Google or directly as SAS.com would allow you to find the solution.
I'd suspect that you then would connect to an Oracle schema using this connector in OWB.

OWB 10gR2 - some enhancement requests

Hi, I've been working with OWB 10gR2 for approximately a week now, and I've come across a few (minor) bugs, as well as a list of enhancements that I think would make the tool better. I'd like to surface these in this forum so they can be either disagreed with or have workarounds suggested, as well as getting this list in front of Oracle. Also I'm new to the tool, so maybe there are ways to accomplish what I want.
p.s. as a side note - please don't take these as criticisms of the tool. I'm actually very impressed with OWB 10gR2, but just want to surface some ideas that I think would make the tool better.
Thanks,
Scott
---Bugs:
1.     If I enter a quote character in one of the business description fields (i.e. for a cube or dimension), it causes the DDL scripts to blow up. It probably mentions the list of valid characters in the users guide somewhere - but if a character isn't legal, it should be flagged when I try to enter it originally not when deploying
2.     I can enter illegal strings in an expression operator that fail validation there, but the whole map still passes validation. For instance, I put in an expression (for a varchar2 field) using a single quote at the start, but mistakenly with a double quote at the end. I didnt bother to validate this within the expression. The whole map validated fine, but (of course) blew up with the illegal syntax when generating the code.
3.     I get the following error when trying to browse a cube (ROLAP, not MOLAP) through OWB, but I'm able to pull the cube up fine using either the excel add-in or biBeans: CubeDV_OLAPSchemaConnectionException_ENT_06952???
---Enhancement Requests:
1.     Add a deploy button in control center next to the to default actions and reset actions buttons
2.     Allow an option to have dimensions and cube defaults set to either deploy all, deploy data only, deploy catalog only, deploy aggregations (for cubes). Also, why is the default set to deploy data only? Does deploying the CMW2 metadata involve huge performance impacts or something? It seems like the CMW2 is almost free so it should be turned on by default. Its a pain to use the dimension wizard, but then have to go in to each dimension afterwards to set this option.
3.     When using configure on dims and cubes in control center, the first time the configuration properties dialog pops up, everything is fine. However, when you try to configure the 2nd object, the background focus switches from control center back to design center. This makes navigation very slow if you have lots of items to change. I've noticed this behavior in a few other places as well.
4.     Some dialogs do not have maximize buttons (i.e. dimension wizard dialogs), and default to a very small size. It is possible to have size of dialogs dynamically scaled to screen resolutions, and attempt to size columns so they fit properly. Or better yet, have each dialog remember how large it was last time, and automatically open up to that size?
5.     When generating the autobind relational table while creating a dimension, it seems to be randomizing the order of the attributes within a level (although it does sort the top level attributes first, followed by lower level attributes), at least when using the dimension wizard. It would be nice if the attributes in the relational table came out sorted in the same order as they are specified in the attributes tab.
6.     When using a unmapped display set there doesnt seem to be a way to refresh the set (i.e. remove the items that have since been mapped) unless you select all and then unmapped again. Would be nice if you could simply choose unmapped again and have it refresh the object
7.     While doing a mapping, right click on canvas allows option to generate. Would be nice to also add the validate option to this menu
8.     Validating mappings takes a decent amount of time would be nice if a busy icon was displayed to let user know that OWB hasnt locked up.
9.     default size of job details dialog is too small, and even if I maximize I still have to go through and manually adjust the size of each pane. Similar to enhancement #4
10.     Horizontal size of operators in mapping seems to be determined by the length of the operator name, instead of tying directly to the icon. Looks strange. Very minor
11.     When displaying dimension objects in a mapping:
a.     For the surrogate key columns add an icon to indicate this attribute is a surrogate key. Likewise, since its not legal to map anything to this column, remove the little arrow next to it (the one that turns gray when something is mapped to a column), or perhaps don't even show this column at all.
b.     For the business key columns add some type of icon to show which attributes represent the business natural key (or make color different, etc.)
12.     Similar to #11, for the cube operator in a mapping:
a.     For the surrogate key columns if they cant be mapped to, then dont show them
b.     For the business key columns add some type of icon to show which attributes represent the business natural key
c.     Separate the measure columns from the dimension columns
13.     For the Aggregation operator can you move the <None> default operator to the top of the list. At the bottom, it means you always have to scroll to use the most common operations (which are at the top of the list), i.e. sum and avg, etc.
14.     In the log on prompt, if I choose SQL*Net connection, every time I start it up it defaults to the details being shown (even when I chose no detail last time), with cursor in the host box. I should be able to have the details hidden, and this dialog should ALWAYS default to having the active cursor in the password box on startup
15.     When printing in a mapping, the page setup print dialog is very slow. Also, the print setup dialog shows margins, but you cant adjust them. It would be nice if this could be changed here
16.     Add a print preview icon to all of the toolbars. Printer icon is there, print preview should also be.
17.     In the dimension attributes, we need a way to tag an attribute as being the insert record date or the update record date. The corresponding MERGE SQL should be updated to use these attributes.
18.     It would be nice if the mapping canvas defaulted to an unlimited sizei.e. when I want to add new operators and the screen is already full, I either need to shrink the zoom factor down to the point where I cant read the icons anymore, or I have to pick up the new operator and drag at the bottom / right side until it scrolls enough to drop it where I want. If the canvas had an unlimited size, I could simple use the scroll bars to scroll to where I want.
19.     Scroll wheel functionality to zoom in / out (and have it zoom in around the currently selected object)
20.     Option to have operations automatically resize when longer attribute names are added to them (can workaround by mimimizing and then maximizing, but would be better to have the operators automatically adjust size to fit)
21.     Ability to sort output attributes in an operator (just like table column sort functionality). If I create a new operator, it would be nice to group it with related operators instead of always having it at bottom.
22.     re: column sort functionality drag and drop instead of up/down arrows would be nice
23.     It would be nice if, when adding output attributes to (for example) the expression operator, it would choose the default data type the same way the dimension attribute wizard works (i.e. if it sees ind in name, automatically choose char(1)
24.     Change the zoom in button so that it zooms in on the currently selected operator i.e. if I click on a particular table and then hit the zoom in button, it should keep the table I selected centered
25.     When in a mapping, clicking on a line should highlight the attributes on both the source and target operators (to allow easier visual ID of where data is coming from / going to)
26.     AWM has a feature where table attributes can be sorted so that mappings between them don't have "crossed" lines. Similar functionality in OWB would be very appreciated. It may be harder to automate this, but even manual drag and drop of attributes within an operator would be nice.

if you could copy/paste this whole thing into the submission form (see feedback option under the numbers menu). The more people that request these features, the more likely we are to see them in an update or the next version.

OWB 10gR2 : How to configure ctl and log locations for Sql*Loader mappings?

Hi all,
I'm using OWB 10gR2 to load data in tables with Sql*Loader mappings.
In my project I have a datafile module and an Oracle module.
When creating an sql*loader mapping in the oracle module, there is two properties for this mappings that I want to modify. The first is Control File Location and the second is Log File Location. Values for those properties are equal to the data file module location. When trying to change those values I can only chose "Use module configuration location".
Somebody knows how to configure those properties with different locations as the one of the flat file module?
What I want to do is to store the data file in one directory, and control file and log file in other directories.
Thank you for your help.
Bernard

Hi,
You're right, my problem is that the dropdown only show the location associated with the flat file location even if I have other file locations created in the design repository.
The good news is that I have found the solution to solve the problem :
1) Edit the file module and in tab "Data locations", add the locations you want to use for control file and log file.
2) Open configuration window of the mapping and then the dropdown for properties Control File Location and Log File Location show new locations
I have tested my mapping after changing those properties and it's working.

Storing degenerate dimension info in an OWB 10gR2 cube

Hi,
I'm looking to store "degenerate dimension" information in an OWB 10gR2 cube. Typically in a DW, I'd just add a column to the fact table to hold the information. However, in OWB 10gR2, I don't see any way to add a column to a "cube" object - everything appears to either have to be a dimension surrogate key, or a measure.
Not sure the best way to proceed. We've coded all our ETL using the standard cube objects and letting OWB do all the surrogate key lookup, etc. automagically for us, so I'd hate to be forced to go back to manually loading the fact tables. Is there an easier way?
Thanks,
Scott

Hi Scott,
The problems I've run into with dimensions and cubes are:
Dimensions abort if there are many roles - about 4 is the limit. This is very bad for the time dimension which should have 100s of aliases. Unfortunately I can't use the Time dimension wizard because we require ISO-Weeks. My workaround is to create several Time dimensions manually and assign 4 roles to each.
Naming - when I create several time dimensions with 4 roles each (see above), in the BI layer, the foreign keys in cubes are always named something like time_dim, time_dim_1, etc rather than named for role names. I have to manually rename them in tables and then when I deploy BI objects, manually rename them again in Discoverer Administrator.
Redeploying just about anything is broken. Table upgrade plans are invalid (even after running the grant scripts that support recommended), Redeploying BI objects runs successfully but if you read the job output, it does nothing since the objects already exist - again, the upgrade option does nothing.
Column ordering is random when deploying objects so I've taken to sorting alphabetically for our BI objects. Not ideal by any means.
As for the time savings with lookups, I don't save nearly that much. Due to many composite keys in our source systems, I assign surrogate keys in our staging area. These become the "business keys" in our DW layer and consequently I end up doing lookups against the staging MAP tables - really no more or less difficult than looking up dimension keys. That is more a design choice than anything and may just be my "Kimball" habits dying hard.
I'm encouraged to hear that you are having success. I chose to utilize the Dimensions and Cubes and so far am sticking with it. I'm hoping that there will be patches and/or point releases to OWB soon!

OWB 10gR2 - Implementation Strategy

I am trying to find what is the best strategy to install and configure a OWB environment for the following scenario on one linux server machine:
There are three Oracle databases on this machine:
database 1 = OWB repository owned by a owb_owner schema. The repository will contain all of design metadata (Source Oracle module with source tables, Target "Oracle module A" with tables, sequences, mappings and Target "Oracle module B" with tables, sequences, mappings). The ETL process is setup to transform data in two stages: 1> Source to target A 2> Target A to target B
database 2 = It will have target schema Target_A. The contents of "Oracle Module A" from the OWB repository in database 1 needs to be deployed to this "target_A" schema
database 3 = It will have target schema Target_B. The contents of "Oracle Module B" from the OWB repository in database 1 needs to be deployed to this "target_B" schema
Do I need to have OWB repository installed in database 2 and database 3 and have control center service running in each of them to facilitate execution of ETL process?
Deployment of the objects will be launched from a windows workstation via client design center / control center manager. Do I need to have control service running from client machine to facilitate deployment ? If so, would it facilitate deployment of the objects to the above two targe schemas ?
The intent is to have a process flow in OWB metadata repository of database 1 streamline the complete ETL process tied to a location owned by OWF_MGR schema in database1.
Please advice what implementation strategy will work best for the scenario. I read strategy presented in http://download.oracle.com/docs/cd/B31080_01/doc/install.102/b28224.pdf .. BUT I need more clarity on the available options.

Hi.
you will need a unified repository in each database. The unified repository in OWB 10GR2 contains both the objects for the design repository (your mappings, tables etc.) and the control center repository (runtime and deployment information such as execution times of mappings etc.). In previous versions of OWB they were separate.
Database 1: Install the unified repository and just use it as your design repository. You will use this when you log in via Designer.
Database 2: Install unified repository together with Control Center Service and use as control center repository.
Database 3: Install unified repository together with Control Center Service and use as control center repository.
While it is possible to have the Control Center Service just run on a client machine , I ran into all sorts of problems in the past with this configuration, e.g. when you log off your client machine it shuts down the Control Center Service. From my experience this setup is not very stable.
In OWB Designer you can then set up locations and configurations to deploy your mappings to database 2 or database 3.
You will need owf_mgr on both database 2 and database 3 and you need to deploy your process flows to both databases. What you can't do is to run a process flow say from database 1 or database 2 across databases 2 and 3.
Can you explain in some more detail why you have a requirement to transform data across two target servers?

Uli

OWB 10gR2 Merge Feature

Hi
I am trying to create a mapping which uses the merge statement in the end.
Though I just want to have a normal insert and no update.
This is possible in 10g DB wherein we can only have an update or Insert .
However, when I am trying to create the mapping using OWB 10gR2 I am forced to choose an update and insert clause... is there any way I can get around OWB 10g to just create the merge with either Only Update or Only Insert.
Thanks
Sushant

Hi
Thanks for your replies. I do know that I could use either Insert or Update in the drop down menu. However before 10gR2 We didnt have the flexibility of using either one Insert or Update.
For More Information refer to .....
http://www.oracle-developer.net/display.php?id=310
In Oracle 10g, either the INSERT or UPDATE operations are optional (you must have one, but not necessarily both, unlike in 9i). This is a critical enhancement and one which makes the MERGE statement much more flexible. In particular, this new feature could make updates with correlated sub-queries a thing of the past as MERGE is easier to code, easier to understand, more flexible, less error-prone and faster. In the following example, we'll MERGE source into target but ignore new rows by leaving out the INSERT operation. Note how much easier this is to code and read than a "double-correlated UPDATE".
Hence I wanted to try if this is possible using the Warehouse Builder 10g.
Anyways Thanks for your Time
Regards,
Sushant

INVALID SOURCE MODULE

I have worked with OWB for a while, but this is my first exposure to owb 10g, and the 10g database which in the case serves as my source database. I was able to create a target module, and import from my 10g database my target tables. However when I attempted to create my dblink for the source module I receive the following error API4006 (the database link contains invalid info) API2414 (Cannot determine version info for the specified dblink). Please HELP.

Yes my source schema has connect priviledges, actually it has dba priviledges. I also seeded my repository 10g as well. I tried to use the same dblink I setup for my target module and I still receive the error message. I tried deleting the source module and recreating it and got the same result again. I can not understand this error, if I got it for both target and source I would then look to the database install, but I only get this for the source module. I have also tried to create another project and I still get the same error.
