Performing a new installation
Installing a new BIRT iHub creates a default Encyclopedia volume without migrating data from a pre-existing volume. The default installation program performs the following operations:
Installs and initializes iHub and the PostgreSQL relational database management system (RDBMS)
Creates a database in the PostgreSQL RDBMS containing Encyclopedia volume data
Creates the iserver user in the PostgreSQL RDBMS to access the system
Creates the system and volume schema, initializing these schema with basic configuration information
Creates the iHub configuration file, specifying system, volume, and connection information for the default installation
The default installation program also initializes the iserver, system, and volume user passwords to the PostgreSQL superuser password.
