1.0.5 also includes support for the SQLRowcount feature and fixes three bugs: one related to setting the schema on z\OS, another about LOB handling, and finally an edge case about nested queries that were truncated.

To install or update this gem on Windows, simply run:

gem install ibm_db

On Linux, run the following:

sudo -s
export IBM_DB_INCLUDE=/home/db2inst1/
sqllib/include
export IBM_DB_LIB=/home/db2inst1/sqllib/lib
gem install ibm_db

For example, the development section of said configuration file may look like this:

development:
 adapter: ibm_db
 username: db2inst1
 password: secret
 database: db_name
 schema: myapp
 timeout: 5

In this case, the timeout for each connection was 5 seconds.

We hope you’ll find this release useful. Give it a try, and please report any issues, however unlikely they may be, in the RubyForge forum.

Besides a few bug fixes, this version adds support for DB2’s secure connections via SSL, short-hands to use char, double and xml when using both create_table and change_table in Rails’ new “sexy migrations”, and enables change_column_null to work with DB2.

Even more importantly, it adds support for Transactional Migrations in Rails 2.2. What this means to you is that any DDL changes performed by a migration file before an exception has been raised, will be rolled back by DB2. This is a handy new feature in Rails 2.2, and our gem backed support for it, even before this version of Rails was shipped.

Speaking of Rails 2.2, which is about to be released, you’ll finally be able to run rails my_app -d ibm_db. This will generate a DB2-specific config/database.yml file. This move is possible thanks to a patch that was submitted by IBM to the Rails team. As handy as it is, the great news is not so much in this new feature, but rather in the fact that the Rails team has shown that they’re open to accepting patches that extend features to commercial databases as well, and not only the three open source ones they support. This can open up a world of possibilities for the future of DB2 on Rails, and it will mean less reliance on external plugins.

As usual, install as follows (on *nix systems):

$ . /home/db2inst1/sqllib/db2profile
$ export IBM_DB_DIR=/home/db2inst1/sqllib
$ export IBM_DB_LIB=/home/db2inst1/sqllib/lib
$ sudo gem update
$ sudo gem install ibm_db

On Windows, simply run:

gem install ibm_db

Whether you use DB2 with Ruby, Rails or on its own, you too can get involved. And the same goes if you opt for Informix instead. Here are a few suggestions:

1. Head on over to ChannelDB2 and register;
2. Sign up for free with the IDUG or IIUG user groups;
3. Join a Facebook group for DB2 or Informix;
4. Take a moment to respond to even a single question in the developerWorks forums or on comp.databases.ibm-db2 (or comp.databases.informix
5. Send an e-mail to a couple of colleagues or friends and pass on links to ChannelDB2, PlanetDB2, Informix Zone, the XML Contest homepage (which went live today), or other community sites;
6. Find a blog post that you appreciated and take the time to leave a comment saying “thank you”.
7. If you are feeling ambitious, start your own blog about DB2 or Informix, sharing your experiences with the community.

There you have it. And whatever you decide to do, remember that it greatly benefits our community and can help foster its growth. Thank you.

$ . /home/db2inst1/db2profile
$ export IBM_DB_DIR=/opt/ibm/db2/V9.5
$ export IBM_DB_LIB=/opt/ibm/db2/V9.5/lib32
$ sudo gem install ibm_db

Adjust these commands for your paths, shell and architecture (e.g. 32 vs. 64 bits).

Please note that at this stage we don’t recommend that you download the outdated Starter Toolkit for DB2 on Rails. Instead, please grab and install DB2 Express-C, install Ruby through the One-Click Installer, install Rails through gems (gem install rails) and then proceed to install the ibm_db gem as explained above. When you install DB2, ensure to select the “Base application development tools” as illustrated here.

The API team is fully aware of the outstanding issues and is working on bringing DB2 compatibility to Rails 2.1. An announcement in this blog will be made when a new release is available.
