Updated Oracle SQL Developer Migration Workbench Early Adopter Release

We have updated the early adopter release of Oracle SQL Developer Migration Workbench today on OTN. You can get it from here. This is our final preview release, before we go production. We are now functionally complete for this initial production release and are now focused on fixing our final "show stopper" bugs. We have had good feedback from our user community via our feedback application and also via the Workbench forum. They have uncovered a number of bugs, most of which we have now addressed (Oracle9i as a repository and Access data migration issues for example) and the remaining ones we will resolve prior to production. I encourage everybody to update to this latest release and continue to provide us with feedback.

I have been working extensively with different builds of the Migration Workbench these past couple of weeks as we closed in on our goal to refresh the early adopter version. In my "biased" opinion is it looking much stronger and I would like to outline some of the new features in this updated early adopter release.

Quick Migrate
In the orginal Migration Workbench we had a wizard driven approach to simplify migrations and I felt it was important to bring this functionality back. With our Quick Migrate wizard, I believe we have improved from the original wizard, since we will leverage our least priviliege migration capabilities, assume sensible defaults and create/remove our migration repository.



So if you have a schema on SQL Server or a single Access mdb file to migrate to an existing Oracle schema, this should be the easiest and quickest migration option for you. Another nice feature, if you are doing an access migration, is that we have added command line support to our exporter so, we will automatically launch the correct Access exporter for the Access connection that you specify.

Offline Capture
This was a popular feature with our consultants and partner technical services folks, with the original Workbench, as it allowed them to work remote from the customer/partner. We have now added back in that feature.

Migration Reports
We have added in some initial migration reports available under Reports->Shared Reports. This will be an area we will add to into the future, as we can mine our rich metadata repository to provide you with useful information. If you have suggestions for additional reports let me know. I will also publish more details about our repository, so you can develop your own migration reports as well. Maybe we should have a competition for the best contributed report? I think we have a couple of 1GB USB keys left over from our Database Developer Day in Dublin I could use as prizes.

Translation Scratch Editor
We have reworked this feature extensively. I originally wanted to add a feature that would enable you to validate our translated SQL. As we worked through different iterations of how best to implement this feature, we came up with the idea about leveraging our existing Worksheet capabilities, which I think is very cool and I am very pleased with how this turned out.


We have also done a lot of work to improve incremental capture and improve our filtering capabilities from our early adopter release. We have integrated our MySQL parser from the original Migration Workbench and will extend its capabilities in subsequent releases to be as functional as our new TSQL parser and also support SQL statement level translation. (workaround for now, within the scratch editor, is just wrap the SQL statement in a procedure). We have also implemented the ability to update your Access mdb file, to create link tables to point to your newly migrated schema. This was also a feature of the original workbench. We hope to add some additional usability tweaks to create an ODBC OSN on the fly and provide a select list of known Oracle DSN. Hopefully that will make it in before production as well.

We have made fixes to ensure correct generation order for pl/sql procedures to resolve dependencies, so more pl/sql procedures should compile correctly first time. We made improvement to handle inline DDL statements correctly. Temporary tables, normal tables and other DDL are lifted out of the body of the procedure/function and are created separately.

Now for the final bug fix push by the development teams in Dublin and Bangalore. Our QA team, have been doing a good job verifying our fixes and closing off our bugs. The teams have been working hard on this for many months now and I believe we are in touching distance of reaching our goal. It will be very exciting for me personally to see this second generation migration tool reach production. We'll all need some time off when this is done to recharge...

Oracle SQL Developer Migration Workbench Early Adopter Release

Last week we released on OTN the early adopter release of the Oracle SQL Developer Migration Workbench. You can find more details about it here. It was a very important release for us, and marks the start of a new generation of migration tools.

It is nearly 10 years ago when the original Oracle Migration Workbench was released, we supported migrating SQL Server 6.5 to Oracle8 then. At that time, I believe we were the first to introduce a GUI tool. Previously we had provided a series of migration scripts (shell based + SQL) and a stored procedure converter utility. We went on to add support for Access, Sybase, Informix, DB2 utilizing the same user interface by leveraging our plugin architecture. Over the years we have seen our database competitors and others release similar migration tools for their databases.

With this release, I believe we have made the same dramatic shift again that we did back in 1998. By integrating our migration tool as a extension of SQL developer (our very popular tool for database developers) we have provided our users with a modern intuitive UI tightly integrated into an IDE, that should make users even more productive as they carry out database migrations. I don't believe any of our competitors have delivered such tight integration.

This initial release supports Microsoft SQL Server, Access and MySQL. We are introducing support for migrating Microsoft SQL Server 2005 with this release. These third party databases represents the most popular downloads for our existing Oracle Migration Workbench. We will add further platforms in the future. We have also architected this solution, to make it even easier to extend and leverage the rich core migration functionality that we have developed. We hope that others will also extend this tool going forward adding support for additional databases.

The focus now, is on completing some features which missed the cut for the early adopter release, (more on that in a later post) , getting feedback from our user community and fixing as many reported bugs to ensure the highest possible quality release, when we go production, as SQL Developer 1.2. I encourage you to try it out and provide us with feedback. We have setup a comment application which you can provide us with feedback. You can access it here.

Some of my favorite features of this new release includes:
  • Least privilege migration - You no longer need dba privileges
  • Online Data Move - We have enhanced the online data move and provide parallel data move and the degree of parallelism is configurable
  • New T/SQL parser - We have completing rewritten our T/SQL parser. If I'm honest, it was long over due, but this new parser, provides us with the right foundation for a much greater level of automation in converting complex objects (stored procedures, views, triggers)
  • Translation Scratch Editor - allows for the instant translation of Transact SQL or Microsoft Access SQL to PL/SQL or SQL.
  • Translation Difference Viewer - a color-coded side-by-side viewer to display semantic similarities between the source and translated code.
Looking forward to reviewing the feedback from our user community, getting those missing features completed and getting this new tool to production status as part of SQL Developer 1.2
