14.2. Considerations

When you want to run JBoss Portal on a cluster there are a few things to keep in mind:
  • Deploy the portal under the all application server configuration as it contains the clustering services that is leveraged by JBoss Portal.
  • All the portal instances have to use the same datasource : the database is used to store the portal persistent state like pages. If you don't use a shared database then you will have consistency problems.
