Database

HCL Portal includes an Apache Derby database that is configured and ready for immediate use. As a result, you have a running portal that is ready for exploration or portlet and theme development. But for a production environment or any environment for HCL Web Content Manager, you must use one of the other supported database management systems.

Apache Derby

Derby is a built-in Java database that provides a small footprint, is self-tuning, and is ideal for solutions where the database must be hidden. Derby works in a non-clustered environment with a few users, such as a portlet or theme development environments.

Derby does not support clustered environments, enabling security in a database-only mode, or vertical cloned environments in which multiple application servers are configured on a single server.

The Derby database that is installed by default is not supported for use in a production environment.

Apache Derby and HCL Web Content Manager

Use one of the other supported databases in a production environment or when you are developing presentation templates or authoring web content. The Derby database can be sufficient for non-production installations of HCL, the performance of Derby with HCL Web Content Manager is poor. A typical cause of performance issues is transaction timeouts. Although you can increase these timeouts, the resulting performance is prohibitively slow. You must use one of the other supported database management systems. They are better able to handle large amounts of data and can be tuned for performance.

Apache Derby and Site Builder

The use of Apache Derby with Site Builder is not supported on development or production environments.

Database transfer

Transfer data to another supported database before you use the portal extensively. Large amounts of data in the databases can cause the database transfer to fail if your Java™ heap size is not large enough. Do not postpone transferring data to another database management system. Waiting to transfer the database can cause errors to occur during the transfer process, such as not having adequate Java heap size.

Configuration Wizard

Use the wizard to either create scripts that you or your database administrator can use to create databases, create database user IDs, and configure database user ID privileges. The wizard collects information about your database management system, the database topology you want, the user IDs you require, and more. Then, it generated custom scripts and instructions.
