Removing custom JVM properties

In WebSphere® Portal Version 6.1.x, some custom JVM properties were introduced to improve performance. Since Version 7.0, these custom properties are no longer needed and are unavailable, hence they need to be removed before migrating.

About this task

The custom JVM property javax.xml.transform.TransformerFactory must be removed before migrating to WebSphere Portal Version 8.0. This custom JVM property is pointing to a class that no longer exists. If the property is not removed, the WebSphere Portal will not start after migration.

If you are migrating from Version 7.x, should not have this custom JVM property configured.

Procedure

  1. Log in to the WebSphere Integrated Solutions Console.
  2. Go to Server > Application servers > select the appropriate server.
  3. Under Server Infrastructure, expand Java and Process Management > Process Definition.
  4. Under Additional Properties, click Java Virtual Machine.
  5. Under Additional Properties, click Custom Properties.
  6. Find the javax.xml.transform.TransformerFactory property and remove it.
  7. If your source environment is clustered, repeat these steps for each node in the cluster.
