Oracle DRM performance problems?

Have you recently upgraded DRM to the platform and begun experiencing performance problems? If so, you’re not alone. Scanning discussion boards and internet search sites leads one to the conclusion that many people have taken a performance hit since upgrading to this version. While in a status meeting at my current client, I heard grumblings of slow performance and volunteered to take a look at the issue. After investigating, I have found one significant issue with a relatively easy fix!

As DRM is a Microsoft .NET based application, it is not truly compiled until runtime. When this “Just In Time” compilation occurs, the Framework looks at certain configuration files (e.g., machine.config, web.config, app.config)used during the compilation process. These files contain settings covering key configuration topics such as authentication method, logging options, “global” variables, database connection strings, and compilation options.
One of the compilation options, debug, has a significant impact on the operation of the compiled application.

While looking at the configuration files for DRM, I quickly spotted a common mistake made by development teams releasing .NET code: debug=”true”. While debug=true is great for development teams, it is not great for production software. While I won’t bore you with all of the details as to why this is, the following MSDN blog post covers a fair amount of the differences between an ASP.NET application running in debug mode: Pros and Cons of using Debug=True:

To resolve this issue, do a search for any app.config, machine.config, web.config files contained in your DRM product folder.

For instance, you should be able to locate web.config files in the following folders:

  • %EPM System Home%\products\DataRelationshipManagement\client\web-client
  • %EPM System Home%\products\DataRelationshipManagement\client\migration-client

When you open these files, search for the compilation property. If you see debug=”true”, change this to debug=”false”. For the ASP.NET web applications, these changes will take effect immediately since the Framework will notice that the web.config has changed and will restart the web application.


– Oracle has confirmed this is an issue will address
– We have seen this issue with the following releases: .500 and .304
