# Configuring

Once JReport Enterprise Server has been installed and you have prepared the reporting environment, you can then start it. However, you may find that JReport's default port number conflicts with an existing one in your computer, or that you need to generate log files for analyzing a problem. In these cases, you will need to configure your server. Before or while running the server, you can configure it according to your systems.

The configuration work can be performed in two ways: via the JReport Enterprise Server UI or via configuration files. Some server UI options and properties in the configuration files are mapped and both function the same way. For these types of settings, you can take either way to do the configuration. Appendix 2: Mapping list of server UI options and properties details which server UI option are mapped to which properties in the configuration files.

This chapter focuses on the following topics:

- Configuration files
- Performing administrative configuration work on UI
- Configuring the server database
- Configuring another connection as a substitute for the catalog connection
- Configuring connection pool
- Configuring logs
