| Tóm tắt: | The g in Oracle Database 11g stands for “grid.” The idea is to enable software to access spare processing
power across networks (grids) of inexpensive servers. Traditionally, database systems have been run
on large servers capable of running several very large databases at once. However, there are distinct
disadvantages inherent in the single-server model. For example, resources tied up in the large servers
can’t be redistributed among the various databases and other services to ensure an optimal allocation
of resources. If you need a massive amount of resources to handle your database’s peak needs,
chances are that you’ll run with identical resources throughout the day, thus guaranteeing that you
are going to waste critical resources during low-utilization periods. |
