The configuration settings that vCenter Hyperic server requires to start up are included in the hq-server.conf file. For example, hq-server.conf has properties that tell the server how to connect to the database and where to listen for agent and web application communications.

When you install vCenter Hyperic server, the selections you make, such as port selections, use of plain text, or SSL communications, correspond to properties in the hq-server.conf file. The configuration settings that you supply during installation are saved in ServerHome/conf/hq-server.conf.

In addition to the properties that reflect installation choices, hq-server.conf contains properties with default values that you can modify after installation, based on the your environment and the size of your vCenter Hyperic deployment. For example, there are properties that set defaults for database and JMS configuration options.

Every time vCenter Hyperic server starts, it reads the values of the properties in hq-server.conf.

The vCenter Hyperic server supports some properties that do not appear in hq-server.conf unless you add them explicitly.

After you change values of properties in hq-server.conf or add new properties to the file, you must restart the server for the new settings to take effect

Some of the configuration data that governs the vCenter Hyperic server behavior is stored in the vCenter Hyperic server database. For example, the data that the vCenter Hyperic server needs to contact a vCenter Hyperic agent is stored in the vCenter Hyperic database.
