Corba and minor error codes

Corba errors are hard to understand when no guide is available.

The following link: http://www.omg.org/docs/omg/03-12-02.txt shows the meaning for the minor error codes that might show up.

JBoss XA datasources and mbean error

When deploying an application on Jboss that used Oracle and XA datasources, the following error croped up:

org.jboss.deployment.DeploymentException: Trying to install an already registered mbean: jboss.jca:service=OracleXAExceptionFormatter

It took me a while to found out what the issue was, and the lead to the solution was that the error moved from datasource to datasource according to it’s name, namely the xml definition filename.

The issue is quite simple: XA datasources can only have one mbean definition for the OracleXAExceptionFormatter, so choose one, and only one and put the required definition:

<mbean code=”org.jboss.resource.adapter.jdbc.vendor.OracleXAExceptionFormatter”
name=”jboss.jca:service=OracleXAExceptionFormatter”>
<depends optional-attribute-name=”TransactionManagerService”>jboss:service=TransactionManager</depends>
</mbean>

Remove this definition from any other XA datasource and theerror should disapear and all datasources can bound now without any errors.

Restoring SQL backups from one server into another

Well as you may know I’m amnesiac… So this post is for me to remember how to relink an database user into the database server again.

The stored procedure of SQL Server that does that is: sp_change_users_login…

Light Graffiti

Sometimes something comes along that is quite amazing. Most of the today’s graffiti is pure rubbish and this includes tags and someone that stumble upon a spray can and “draw”…

This is the next level and it takes far more will and inteligence that the “normal” artists.
