New version of the DB2 Ruby on Rails support is out

Our development team just released version 1.1.1 of the IBM_DB gem which provides support for using Ruby on Rails with DB2 and IDS. The new gem provides support for Activerecord 2.3.3 and a fix for a defect that will let us implement support for a popular Ruby on Rails application. Antonio Cangiano will no doubt blog about this as soon as he is done (any day now).

JRuby team leaves SUN/Oracle and goes to Engine Yard

Oracle’s acquisition of SUN seems to be unraveling in a number of areas. Citing lack of certainty (guess it means “uncertainty”) the JRuby team decided to leave SUN/Oracle and join Engine Yard. As Antonio Cangiano pointed in his blog, JRuby is indeed critical to the adoption of Ruby on Rails in the enterprise. Given Engine Yard’s commitment to Ruby on Rails this is a great move for the Ruby community. We wish JRuby and Engine Yard teams the best.

DB2onRails.com will be cheering  for you!

Support for Ruby 1.9.1 and Rails 2.3 is here

The IBM API team just released a juicy update of the ibm_db gem. Version 1.0.5 packs support for ActiveRecord 2.3.2, which is included in the latest, recently released version of Rails, as well as being compatible with Ruby 1.9.1 (you can read this post of mine to learn why this is important). To be more exact, this release enables the driver to work as a ASCII driver when using Ruby 1.9.1, with Unicode support to follow in upcoming releases.

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

IBM_DB 1.0.2 released

A few days ago the IBM API team released an update for the Ruby driver and Rails adapter for IBM databases. This specific release of the IBM_DB gem (1.0.2) fixes a couple of LOB related bugs that were recently found, and adds support for the timeout parameter for ActiveRecord. In practice this means that you’ll now be able to specify a timeout value within your config/database.yml file, which expresses the amount of time in milliseconds seconds before an attempt to establish a connection with DB2 timeouts.

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.

A major milestone for DB2 on Rails

The IBM API development team has released version 1.0 of the ibm_db gem, which includes both the Ruby driver, and the Rails adapter, for IBM’s databases. This is a very important milestone for the DB2 on Rails community, and it ships with quite a few goodies.

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

7 ways to contribute to the DB2 and Informix communities

The community surrounding DB2 is steadily growing, both within IBM and outside. Today is the first Online Community Action Day during which IBM invites IBMers, and information management product users in general, to actively participate more in the community.

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.

New support for Rails 2.1

Support for Rails 2.1 has been added to the latest version of the ibm_db gem (0.9.5). To install this version run gem install ibm_db on Windows. On Linux run the following:

$ . /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.

DB2 and Rails 2.1

Rails 2.1 was released last week at RailsConf 2008, in Portland. Despite being a “minor version” increase from 2.0.2, it introduces quite a few changes. Some of these affect the DB2 adapter, so it is recommended that you don’t upgrade to Rails 2.1 yet.

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.
