OWB 10g/11g version control

I am using OWB 10g release 2 but there is no feature for version control. The snapshot feature and export/import can help but Its very difficult with big project.
Is there any new feature with OWB 11g release 1 or 2 for version control ? Do you have any proposition for version control in 10g ?

Hi Robin,
In the repository there can be only one version at the moment. If you have to work on an older release, you have to load it into another repository.
We proceed as follows:
1. Build a collection containing all objects that belong to the release
2. Export that collection
3. Check the file into CVS
4. Import the file into production repository (in production db)
5. Deploy from the production repository to the production target schema
That way the release that is currently deployed on production is also in the production repository. You may do hotfixes directly here or just have a look at what is currently deployed.
In our development repository we can work on new features.
I gave a talk about automating this process on DOAG 2008. You may request the presentation here [http://www.metafinanz.de/leistungen/leistungsbereiche/bi-reporting/data-warehousing/kontaktformular/|http://www.metafinanz.de/leistungen/leistungsbereiche/bi-reporting/data-warehousing/kontaktformular/]
Though the slides are in german they show the architecture and should give you some idea.

Carsten.

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

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.

Oracle 10g R2 - Metadata Issue With Version Controlled Resources

We are trying to utilize the Oracle 10g R2 feature that allows user-defined metadata to be attached to XML DB resources. However, we are encountering errors when we try to append/attach metadata to a version-controlled resource (VCR). The following steps were followed:
1. Register a new schema to be used for metadata (XMLSCHEMA.registerSchema).
2. Add a new resource to to the XML DB and make it version controlled (DBMS_XDB.createResource and DBMS_XDB_VERSION.makeVersioned).
3. Checkout the newly created version-controlled resource (DBMS_XDB_VERSION.checkout)
4. Add metadata to the version-controlled resource (DBMS_XDB.appendResourceMetadata)
However, after step 4, the errors shown below are encountered:
========================================================
begin
ERROR at line 1:
ORA-00600: internal error code, arguments: [qmxStrCopy: INLOB 2], [], [], [],
ORA-06512: at "XDB.DBMS_XDB", line 890
ORA-06512: at line 2
========================================================
The steps followed for adding metadata to a resource were taken from Chapter 26 of the "Oracle XML DB Developer's Guide 10G Release 2" (http://download-east.oracle.com/docs/cd/B19306_01/appdev.102/b14259/xdb_repos_meta.htm#sthref2302).
Is is possible to append and maintain metadata to an XML DB version controlled resource (VCR)? If so, what are the correct steps to do this? Note that if this is tried with a resource that is not version controlled, then no errors are encountered.
Thanks,
Steve

It appears that this issue has been solved in the next release of the database

OWB Process Flow - How is the best version control tool ??

HI all,
I just start work with OWB and I have a question to know how is the best way to do something.
Imagine the scenario below:
If I have 2 or more requests for example:
Request 1: Create a Dimension City.
Request 2: Create a Dimension Products.
I Have ONE process flow and i need put my changes inside. This is my problem.
In my scenario I don't know what Request goes to Prod First.
If I put the Request 1 and Request 2 in my PROCESS FLOW, maybe I need change is someone decide change MY REQUEST PRIORITY.
There is something in OWB to "control the version or changes" ?? For a mapping I export the MDL and commit on SVN, but I dont know haw can i do with the process flow.
Something to agree multiples peoples work in different mappings and a SAME PROCESS FLOW ??
What is best way to work with process flow and version control.
What are the best practices when it comes to version control?
Thanks.

Amit,
Are you really doing this in 10.1.3.x and not 11g?
At any rate, I don't see how #2 and #3 relate whatsoever to your choice of a version control system. OK, maybe in #2 if there is some "maintenance" activity to be done against the version control server. Subversion is the open source alternative that you listed there and is pretty commonly used. If your company is already using one of the mentioned tools, why change? About the only thing I'd mention is to advise you NOT to use CVS for well documented reasons (JDev does support it) - if you would have picked CVS otherwise, choose Subversion. As far as question #1 - I've only used Subversion (well, I did use CVS for a while) with JDeveloper, so I can say it was "effective enough for me." In 10.1.3.x, I also used the external svn tools for doing lots of things like merging and so forth; in 11g, the support is much much better.
Best,
John

OWB 10g Release 1, version 10.1.0.3, windows client download

Hi,
I am looking for the windows client for the OWB version 10.1.0.3. I am not able to locate the software download anywhere in the Oracle website, could not locate the archive location from where I could download older versions if any.
Any help locating the download in oracle site or in any other means is appreciated.
Thanks in advance,

Thanks for your response...
Yeah, I have a client running 10g R1 version 10.1.0.3 server and the only client installed windows machine crashed and they are using the client on the server. It would be very useful if they could have the windows client for that specific version.
We are also doing a fresh install of OWB 10.2.0.5 on a new server and trying to create the repository and import the .mdl project backup from the prod server (OWB 10.1.0.3).

OWB 10g: how control files are generated?

We are using OWB 10g within a 10g Database. We want to know how control files are generated by OWB in the file system. The reason we need to know is because our DBAs do not want to create directory objects pointing to NAS devices, their policy states that all directory objects should be on SAN shares. We rather use NAS shares since it simplifies our batch (too long to explain here). OWB has the "CREATE ANY DIRECTORY" privilege granted. Is it using this privilege to create a directory object for the path we specify the control file in the mapping or is it writing directly to this path? We checked the directory objects created (SELECT * FROM DBA_DIRECTORIES) after deploying a control file and it didn't seem to have created any new ones. Anyone knows how OWB creates these control files?

Yes, indeed that's what we were after. We basically wanted to be sure we are not breaking an internal policy that says that "Oracle directory objects can not be located on NAS shares". The reasoning behind this policy is that NAS shares are not deemed highly available or high I/O devices hence our Oracle DBAs will not allow us to create any Oracle directory objects in NAS shares. The policy states that all database data should be stored in SAN shares which are directly attached to the servers and are therefore high I/O devices. It is arguable if the OWB data we want to load is really part of a database, we believe it is not. There are other implications in our environment about using NAS instead of SAN (NAS can run in active-active mode across different data centres, whereas SAN requires replication since it doesn't usually work well in an active-active mode across different data centres). So based on your answer we should be fine since OWB reads and writes directly to the files without using Oracle Directory Objects which supports our theory that these are not DB specific files and are only "OWB App" files which can then sit on a NAS without breaking the above stated policy.

We needs driver multiple cover following with version 8i,9i,10g,11g r2
now lastest we can download ojdbc14 could connecting 8 ,9 10 only
please suggestion .
Many thanks a lot for advance .^^

I hope you are not running under Java 1.4. If you are using Java 5 or up, you can use OJDBC5 or OJDBC6 (the number indicates for which version of Java it is built). Both these driver series support connecting to the Oracle versions you mention.

OWB 11gR2 - Version Control ?

OWB 11gR2 - Version Control ?
=======================================
I am using OWB 11gR2 (11.2.0.1) on Win XP 32 bit. We have our OWB repository is on Unix server.
I am thinking of implementing version control of OWB artifacts.
I searched the past posting of this forum/Google. I find some hits, which were posted awhile ago.
What is your solution for OWB 11gR2 version control ? I need to find that kind of solution too.
Any best practices suggestions are welcome.
Thanks in helping this thread alive.

We are using Subversion where folder structure copys OWB tree structure. Every object is exported to separate mdl file. Also we store all DML scripts in separate forlder. After developers have finished their changes they manually gather affected objects to collection. We have written build/export/import tool (OMB+, ActiveTcl, ANT, SQLPlus) that they use next to export OWB objects aumatically from OWB structure to Subversion structure. Changelist with links to exported objects is aumatically maintained. Based on that release package is created at buildtime containig mdl files from Subversion. Release package is also stored in Subversion. When installing release to another environment (TEST, PROD) package is aumatically downloaded from Subversion, mdl files imported to OWB and deployed, DMLs executed in database.

Accessing OWB 10g Respository through OWB 11g Client

We have an Oracle Database 10.2, we installed OWB 10.2 and created a repository.
I want to install OWB 11g Client and use the existing repository. Is this Compatable.
Thanks in advance for your suggessions.

No, there were substantial repository changes in OWB 11g, you cannot connect an OWB 11g client with an OWB 10g repository - but you can host an OWB 11g repository in a 10g database though.

OWB Development Version Control

Hi
CAn anybody throw some light on Version controlling in OWB, I mean how we can do the verion control for the mappings and transformation that are developed in OWB.
Any response for this is greatly appreciated
Thanks

Hi Balaji,
What release are you running?
In version 9.0.4 and higher you can use snapshots to do version management within OWB itself. You can research this in the documentation under Snapshots.
