Mappings disappeared in OWB...

I have a problem with several mappings that have disappeared from OWB. If I try to export the entire project to an MDL, it will fail. If I try to recreate one of the mappings, it says the object already exists.
Is there any way to recover the mapping? Luckily, we do have backups of the repository, but I'd prefer not to have to rebuild everything from a previous version and merge changes.
I am using OWB 9.2.0.2.8
Thanks.

I had the same problem happen to me. I could not discover a logical explanation (I thought I might of mistakenly deleted it, until I saw your post). I did notice that the package existed in the repository schema. I dropped the package from the repository schema (via Toad or SQL PLUS) and recreated the mapping from scratch, painful but it worked. I am concerned that this may happen again if anyone could shed further light to this situation, it would be greatly appreciated.

Menu bar, tool menus disappeared in OWB suddenly

Hi,
Menu bar, tool menus disappeared in OWB 10g r2 mapping edito . Am able to see those in the design center and pluggable mappings. Please help me in finding out this ....

Thanks a lot ..
Its working fine now..
I have few doubts regarding transportable modules in oWB
1.) can I transport objects from one schema to another schema in the same database.?
2) I am working on a database on remote machine. Owb 10g r2 is installed in my machine with that i created a repositoy in the database in the remote machine.
while doing export and import where will be the dump files stored in this operation
in my machine or remote on..??
could you please help me on this

Some Qs about mappings generated by OWB 11.2

1. it is possible to setting OWB do not generate temp stage table (table in owb$temp_tables)
2. in some mapping I see pl\sql code
IF get_trigger_success THEN
Truncate_Stage_Tables;
NULL;
END IF;
but in others only
Truncate_Stage_Tables;
NULL;
how I can it control?

Hi
I don't think there is any option for the dimensional mappings that get generated to not have the staging tables, the best you can do is call the truncate_stage_tables procedure afterwards to clear any data. The tables were needed to provide some of the hierarchy management and loading functionality.

Migration of OWB Mappings in to ODI Interfaces

Hi Experts,
I have build some good amount of mappings in the OWB (oracle WarehouseBuilder) 11g and now i need to migrate all those in to Oracle Data Integrator 11.1.1.5 so my query is
1) Is it possible to migrate with out any additional migration tool, is so please let me know the steps of migration??
2) If it can be done only through any additional tool , what is that tool?? and process of migration using the tool.
Please do the needful. awaiting your inputs.
Many Thanks,
Pavan Kumar

Hi Pavan,
1) Unfortunately not. In its latest statement of direction, Oracle said that with ODI 12c, you will be able to execute and monitor OWB jobs. A migration utility will also be available at this time. But some manual work might be required as well. http://www.oracle.com/us/products/middleware/data-integration/odi-statement-of-direction-1922235.pdf
2) There is no tool for the moment. You can use groovy to automatize part of your migration and do the rest by hand. Here is a presentation by Michael Rainey : http://www.rittmanmead.com/files/ukoug2012_rainey_odi.pdf
Hope it helps.

Using Scheduling in OWB 10.2.0.1 (Paris)

Dear all after some clarification on the use of scheduling in OWB 10G R2. We have just installed this version but i have a couple of questions surrounding the scheduling, may i point out that i have no knowledge of schedling in OWB so am relying on the user manual. It states that in R2 for each project it creates by default a MY_CAL_MODULE where you can then create schedules. Having got 10G R2 installed i cant see either Calenders folder or this MY_CAL_MODULE it talks about. I must also point out that at this stage we do not have Workflow installed because R2 relies on 2.6.4 of workflow but we can only find 2.6.3 or 2.6.3.5 on OTN (we are waiting for an Orcale rep to confimr if 2.6.4 exists). My thoughts maybe that OWB gets its calender from workflow but this is an assumption. Is there anyone out there who has any experience of Scheduling mappings direct in OWB R2 Paris who could advise how it needs to be set up it would be very much appreciated

Hello
Workflow is part of the actual database distro. It will be in the extras download, the same one where you would find HTML-DB
So for your version of database, locate the extras download, and you will find the small apache server, workflow db install, and mid tier along with html-db. Depending on your version of DB you need to install the apache server first, then workflow schema, then mid tier
If you get the client download for the db you have the option of installing the actual WF builder client.
There will be install docs too.

DB link using in the mappings......

Hi OWB Gurus,
I have two schema's named (A,B) in a Instance.I developed some mappings by using OWB in schema A.while developing mappings we are using some of the tables in schema B.I checked SQL query generated by OWB mapping.In that mapping query it is using DB link to call tables in schema B.But with in the same instance it should not use the DB link to call the table in other schema.Do i need to set any configuration option in OWB to avoid using DB link with in the same instance.
Please give me the solutions or work around for this problem if any one had same kind of experience in the past.
Thank You
Best Regards
Kumar

Hi Kumar,
Which version of OWB are you using?
Assuming you are using OWB 10.2 or newer, it is important that the two locations A and B have been registered in the Controll centre with the exact same information. I.e. if one is registered with host="Servername" and the other has host="Servername.domain" this can cause OWB to create a connector using a DB-link. So the first thing I would check is that the two locations are identical except the user name and password. If you do make a change to the registration of one of the locations you need to redeploy the connector.
Hope this helps,
Roald

OWB Change Management/Version Control Best Practice

Hi
I am about to start developing a data warehouse using OWB 10g R2, and I've been doing quite a lot of research into the various deployment/change management/version control techniques that can be used, but am still unsure which is the best to use.
We will have 2-3 developers working on the project, and will be deploying from Development, to Test, to Production (each will have a separate repository). We want to be able to easily identify changes made between 1 release and the next to have a greater degree of control and awareness of what goes into each release. We also wish to use a source control system to track changes (we'll probably use SVN, but I don't think that the actual SCS tool makes a big difference to our decision at this point).
The options available (that I'm aware of), are:
1. Full MDL export/import.
2. Snapshot MDL export/import.
3. Manual coding of everything using OMB Plus.
I am loath to use the full MDL export/import functionality since it will be difficult, if not impossible, to identify easily the changes made between 1 release and the next.
The snapshot MDL export/import functionality is a little better at comparing releases, but it's still difficult to see exactly what has changed between 1 version and the next - particularly when a change to a transformation has been made. It also doesn't cope that well with tracking individually made changes to different components of the model.
The manual coding using OMB Plus seems like the best option at the moment, though I keep thinking "What's the point of using a GUI tool, if I'm just going to code everything in scripts anyway?".
I know that you can create OMB Plus code generation scripts to create your 'creation' scripts, but the code generation of the Alteration scripts seems that it would be more complicated than just writing the Alteration scripts manually.
Any thoughts anyone out there has would be much appreciated.
Thanks
Liffey

Well, you can also do per-object MDL exports and then manage those in your version control system. With a proper directory structure it would be fairly simple to code an OMB+ Script that scans a release directory tree and imports the objects one by one. I have done this before, although if you are using OWB as the primary metadata location for database objects then you have to come up with some way to manage object dependency order issues.
The nice thing about this sort of system is that a patch can be easily shipped with only those objects that need to be updated.
And if you force developers to put object-level MDL into your version control system then your system should also have pretty reporting on what objects were changed for a release and why.
At my current job we do full exports of the project MDL and have a deployment script that drops the pre-existing deployed version of the project before importing and deploying the new version, which also works quite well - although as you note the tracking of what has changed in a release then needs to be carefully managed elsewhere. But we don't deploy any of our physical database objects through OWB. Those are deployed from Designer, and our patch script applies all physical changes first before we replace the mappings from the OWB project. We don't even bother synching the project metadata for tables / views / etc. at deployment. If the OWB project's metadata for database objects is not in sync with Designer, then we wind up with deployment errors. But on the whole it works pretty well.

Deployment from owb hangs

Hi,
I am using OWB10gr2 and it was working fine
and I was able to deploy and run all the mappings.
Suddenly owb started taking long time for
deploying mappings and it showed status as busy deploying
but it never finished and I had to drop the process and
after that If I login again it deployed fine but gradually
this problem became more frequent and now I am not
able to deploy anything.
Please let me know if someone faced same problem and any solution for same.

HI,
In our case also deployment stops at BEGIN wb_rt_notification.wait( :1 , :2 ,
:3 , :4 , :5 , :6 )
; END;
We have set up OWB in such a way that design repository is in one instance
and we deploy code on different instances and have runtime installed on all other
instances .For all other instances it works fine and for this instance also
it was working fine for last three months but suddenly we started getting this
problem and it is not consistent some time we are able to deploy but other time
we just cannot.Tried everything bounced database even installed runtime again in this instance nothing worked .

Differece between OWB and ODI

Dear All,
I would like to know how OWB is different from ODI and would appreciate any resources to understand how OWB 10g works, how to create mappings, what is OWB 10g architecute and so on.. I know how ODI works but do not have any idea how OWB works since I never worked on OWB.
I wont to learn OWB 10g.
Thanks and Regards

Creating Process Workflow

Dear All,
Dear All,
I had some mappings in my OWB and I don't want to run them individually, I want all of them to run at once in a specific order by a single click.
I read that i can do that with Process flow. Im using OWB 10.2 R2 so I tried to create process flow and get following error while creating its location:
"RPE-02053: The Oracle Workflow version cannot be retrieved. This may have been caused by an incomplete or incorrect installation of Oracle Workflow or the schema may not contain an Oracle Workflow repository. Please check the location details, reinstall Oracle Workflow, if necessary and try again."
But i dont really understand what this error means. Is there anything special i should act on?
its catched my eyes that as i was creating the Processflow module and so on, it was not possible to add it in the location where my target and sources are! I must created a new Location for the Process flow.
Please let me know, what i can do.
Thanks & Regards,
vinzi

Create Process Flow

Dear All,
I had some mappings in my OWB and I don't want to run them individually, I want all of them to run at once in a specific order by a single click.
Should I create process flow to achive this? Do I need to install any thing to create process flow.
I tried to create process flow and get following error while creating its location:
"Connection failed.
Io exception: The Network Adapter could not establish the connection"
Please let me know, what is the problem.
Thanks & Regards,
Danish

When I install through Oracle Database home, I get following things for installation:
- Oracle HTML DB
- Oracle Database 10g Products
- Oracle Database 10g Companion Products
In last option, it installs Oracle HTTP Server and Oracle Workflow Middle Tier.
It do not have Oracle Workflow Server.
I had installed last option now and it has successfully installed. It has asked me to provide Work Flow schema and I had given WF as its name. But I am not able to find this schema in my database now. Do I need to explicitly create schema?
Please let me know,
Many Thanks,
Danish

How to add my function as a public function

HI i have a function which i want to make public. How can i do that?
Regards
Vibhuti

Do you mean this:
1. from sql*plus on target-DB: create function public.myfunc .....
2. import this function in OWB-public-custom-transformation
3. use it in any owb-module-mapping ?
Why should I create a function first on the conventional way ?
I tried this way, without success:
1. in OWB create public-transformation, define PL/SQL-code inside (to_number(...))
2. deploy it - it apears as privat function in that shema, which I used in control-center for deployment. there is no synonym in public or anything I can use in other mappings
3. in OWB I choose that deployed transformation in a mapping of another schema
Result: the generated package-body just try to call this function as if it was owned by package-owner ! so it fails !
So than: what means 'Public transformation' in OWB, when it generates the objects in that schema, which I used to deploy such 'public' transformations ?
when it even does not take care to crete a public-synonym as soon as I drag a public-transformation into a mapping ?
why does OWB not generate a full-qualified access (schema_x.function_y(...)) to a draged transformation, since OWB should know, who is the owner of that transformation and who wants to use it.

Default generate scripts in old style instead of ansi joins at designer lev

I have already deployed 1000 owb mapings and default it is showing intermediate result script in ANSI syntax.
Is there a way to change the a configuration property in OWB(ANSI SQL syntax condition to FALSE) for switching between ANSI SQL code generation and Oracle SQL at designer level instead of mapping level?
Plz help.

HI David,
Thanks for u r response.
I have one more question for u
I am trying to execute the some of the mappings in 11g OWB.Mappings are failed with statistics are locked.
How to resolve it?
when this kind of errors will come?

Conditional Join in MAP

Hi,
Is there a way to have a map with 2 tables but join them conditionally.
Need to Update Table C using Table A but join TABLE B only certain condition is met. I can achieve it using PL/SQL procedure by creating Dynamic Select Statements. Can it be done with Maps ?
Appreciate you help in this regard.

Hi,
I would not recommend using views in owb mappings. With views you just hide the complexity of mappings outside the owb, i.e. you cannot tell from the mappings where your data is coming from. You also lose some benefits from lineage analysis.
Regards,
Carsten.Ops,
i would leave it to you to decide whats best for him based on complexity of the mapping , business & strategic approach etc. There are pros and cons and the approach that is best suited to your business should be adopted.

My advice would be to try and convert your data source to a relational table/view and using the mapping editor. This will allow you to benefit from the many new features within OLAP cube storage such as compressed composites, data compression, paralled processing, partitioning and aggregation maps.

Database upgrade to 11gR2

Client upgraded the development environment to 11gR2 (11.2.0.1) yesterday, and now mappings generated from OWB (client is 10.2.0.1.31) to development throw an RPE-01011 (incompatible version) error.
The OWB design repository is in a standalone database. That database has not been upgraded yet (at 10.2.0.4).
Would it be possible to use the 11.2 OWB design "piece" against a 10.2.0.1 repository, or is there a patch available that would allow the 10.2.X client to deploy to a 11.2.0.1 database?

Hi,
I wanted to start a new thread, but this one touches a similar problem:
A customer plans to migrate a huge DWH from 10gR2 to 11gR2; but there are over 2000 mappings which he don't want to re-deploy. In general, this is not recommendable, but would it work at all? A 11gR2 runtime executing 10gR2 generated mappings? My first thought was this "incomaptible versions" error. I haven't the infrastructure to test it on the fly, so I'm asking before answering to the customer.

Thomas
