SolidDB Storage Engine

March 29, 2007

The ATG Creating Commerce Applications course uses the Solid Embedded Engine. So ofcourse when trying to run the Solid Sql scripts in my MySQL database it fails on the following line:

alter table dynamusic_item_bought set pessimistic

This is only natural since this is a typical Solid statement. When googling to see how I can translate this to MySQL syntax I stumble on the SolidDB Storage Engine for MySQL . He this is new! So when I use MySQL with this storage engine will it accept my SQL statement? I have no idea. I am completely in the dark how MySQL and its storage engines actually work. But hey let’s give it a try. Unfortunately there is only a Windows and a Linux version. But somebody on the net compiled the sources for the PowerPC mac and had created a Mac build. Hoorah.

However the following code fails:

`id` varchar(11) NOT NULL , PRIMARY KEY (`id`)

But this one works


It seems that I cannot do a primary key on a varchar. That’s odd.

Next step is to compile the stuff myself. However although I’m perfectly able to compile the MySQL sources from on my MacBook, I get a compile error when downloading the linux sources from the solid website. Must be my inexperience. Solid forums.

So now I’m on Parallels for the remainder 😦 ….

Little ATG annoyances

March 27, 2007

I’m a complete ATG newbie. So perhaps some stuff is due to my inexperience, but things which seem odd to me:

Eclipse ATG plugin

When doing the New ATG Module in Eclipse a manifest is created with


There is a double DAS entry there.


I missed the create J2EE application under the ACC. It seems this is only available if you use DAS. Since I’m using JBoss, this is not available. Why is this?

More items are missing in the ACC. Well the ACC is going the way of the mammoth I guess.


Positive: It seems that Dynamusic from Developing ATG Applications is going to work. The Solid SQL script creating the Dynamusic tables was accepted by MySQL (after removing the drop statements). At least the first chapter worked. Although you have to use Eclipse in stead of the ACC.

ATG, JBoss and MySQL on Mac OS X

March 25, 2007

Since Mac OS X is not a platform supported by ATG , installation can be… a bit troublesome. Everything ATG related is hard to find with Google so I decided to write this down. This is the installation of the ATG 2006.3 version.

At the end perhaps not everything is necessary, but the result works for me.

I found a lot of tips on Nabble by qmnonic . Thanks for sharing

<EDIT on June 15, 2007>

Steps 7, 8 and 9 are not necessary. So you can skip them


Pre installation

  • Have jboss-4.0.3SP1 ready. This is the only version supported by ATG.
  • Have MySQL ready. Only 5.0.20 is supported. However I have used 5.0.27 and so far it seems to be working fine. Make sure you use the InnoDB engine instead of the MyISAM. If you don’t, prepare for the infamous 1000 characters unique key problem. I found this on Nabble. Further integration of MySQL and JBoss is described below. However I used an O’Reilly article: JBoss and MySQL
  • Take care of your permissions.
  • Add export JBOSS_HOME=< your JBOSS path here> to .bash_login. If you use another shell, you know what to do.

Installation and configuration

  1. Download the unix installer ATG2006.3.bin and install ATG. Your life will be easier if you do not use the default space.
  2. Drop your license files in <ATG folder>/home/localconfig
  3. Add Darwin to <ATG folder>/home/bin/ as explained in ATG SolutionID atg33147 as follows:
    1. Add: DARWIN_OSDIR_NAME=”Darwin”
    2. Add: elif [ $UNIXFLAVOR = Darwin ]
  4. Added to <ATG folder>/home/localconfig/ with the next line
    export ATGJRE=/System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK/Commands/java as described on Nabble.
  5. Copy MySQL JDBC driver to <JBOSS_HOME>/server/atg/lib
  6. Add mysql-ds.xl to <JBOSS_HOME>/server/atg/deploy fill in the correct database name etc.
  7. Add MySqlDS datasource to standardjaws.xml as follows:
  8. Edit standardjbosscmp-jdbc.xml (I guess this is not necessary, since it is for EJB’s. But better safe then sorry. I’ll remove it later to see if still works)
  9. Add the following text to login-config.xml (Again I’m not sure is needed, I’ll check this later):
    <application-policy name = “MySqlDbRealm”>
    <login-module code = “”
    flag = “required”>
    <module-option name =”principal”>sa</module-option>
    <module-option name =”userName”>sa</module-option>
    <module-option name =”password”></module-option>
    <module-option name =”managedConnectionFactoryName”>
  10. Create a file, like this: /<ATG_HOME>/home/localconfig/atg/dynamo/service/jdbc/
    The ATG documentation states to create a jbossconfig folder with a change to a manifest to point to that path. I skipped that.
  11. Edit this It should contain:
    and should NOT contain
    This is wrong. error in ATG docs I guess. It results in classnotfoundexception in my case. Leaving it out seems to fix it?!
  12. Run datascripts
    /Applications/ATG 2006.3/DAS/sql/install/mysql/das_ddl.sql
    /Applications/ATG 2006.3/DPS/sql/install/mysql/dps_ddl.sql
    /Applications/ATG 2006.3/DSS/sql/install/mysql/dss_ddl.sql
    I used mysql <dbname> < dss_ddl.sql –user=<user> –password=<password>

After installation

Run by using the script form <ATG_HOME>home/bin folder and use -c atg to use the atg server-config-name.

I sometimes had to delete the ATGDAF.ear from the Deploy folder and retry, when changing some configuration. It seems they are not always recopied.

These steps worked for me to get a basic Nucleus install where the ACC is working correctly.

Good luck
