Understanding Ingres Components
Components of an Ingres Installation
The system administrator installs and maintains the following principal components or associated family of compatible components:
• DBMS Server
• General Communication Facility
• Querying and reporting tools
• Visual tools, if available in your environment
• Logging and locking systems
An installation also has:
• Library files and utilities, provided with the product distribution
• Configuration files and error log files, created during installation and at runtime
• Databases and their associated files: the checkpoint, journal, dump, and work files, also created during installation and at runtime
The locations of these files are selected at installation time, together with the configuration of the DBMS Servers and the logging and locking systems. For the initial installation, default settings are provided by the system whenever possible.
