Outofmemoryexception is very likely to occur when computing requires a lot of memory space. System. runtime. memoryfailpoint provides the memory check function before running computation that requires large memory. When calling this method, perform the following steps (if you do not fully determine the size of the required memory, you can pass an approximate value) 1. Check whether the system's page files have sufficient available space and whether there is sufficient continuous virtual addre
JDBC 5 data source and data pool (web basic learning note 11), jdbc 5I. Why are data sources and connection pools used? Currently, the developed applications are basically data-based and require frequent database connection. If each operation is connected to the database and then disabled, the performance will be limited. Therefore, we must find a way to reuseDatabase connection. In view of this situation, the concept of data source and connection poo
