Multi-core processors brings about the situation in which CPU resource is no longer the limiting factor of performance, and instead, critical sections enforced by means of locks have emerged as significant bott
Scaling out such a system means adding one or more additional computers to the network.In a scaled-out, highly partitioned environment, you should employ a more abstract and hardware independent concept of processing power. The total processing power is the sum of the physical speed of each ...
When you have these relationships, you need to handle them in a cache. That means the cache should know about the relationship between a customer and an order. If you update or remove a customer from the cache, you might want the cache to also automatically update or remove related order ...
To cope with dynamically increasing demands from multiple tenants, the first approach that comes to mind is scaling the system vertically (scaling-up). This means adding resources to a single node in a system, typically involving the addition of processors or memory to a single computer. In ord...
The columns are equivalent to the dbms_connection_pool.configure_pool() settings described in Table 4, with the addition of a STATUS column. The status is ACTIVE if the pool has been started and INACTIVE otherwise. Note the pool name column is called CONNECTION_POOL. This example checks ...

SQL> execute dbms_connection_pool.stop_pool(pool_name => 'my_pool', draintime => 0) This call will immediately abort all the pooled servers in the pool named 'my_pool' and stop the pool. SQL> execute dbms_connection_pool.stop_pool(pool_name => 'my_pool', draintime => 30) This...

Mimer SQL is a 64-bit DBMS which means that the limit of the database cache is 327 Terabytes, a limit that in reality means that there are virtually no limits when it comes to the size. There is no hardware that can match this and this is the problem. Mimer SQL needs a storage sol...
In such cases, only one thread is employed and the potential benefits of parallelism are lost. SQL Server 2008 will recognize such cases and introduce an exchange operator that allocates one row per thread so that all available CPUs are employed. The increased parallelism means that CPU ...
