Before installing Oracle Database 10g, the DBA may need to purchase the future database’s server. The DBA needs to estimate a number of factors that will affect server size: expected data capacity of the database, expected user load, and potential future growth. The DBA must also choose an operating system, the number and speed of processors, the size of disk configurations and memory, and the amount of space to hold backups.
Minimum Hardware Requirements:
Oracle Database 10g requires approximately 4 GB of free hard disk space for a complete, basic installation, including 1 GB of swap space and 400 MB of temporary space. A minimum of 256 MB of memory is required for a basic installation, and a total of 512 MB is recommended for using the Oracle Enterprise Manager (OEM). However, for optimal performance, additional memory should be considered.Sample Database Creation:
The Oracle Database 10g installation gives the option of creating a sample database in addition to installing the database management system. If the DBA chooses not to create a database during installation, databases may be created after installation is complete.
