Without connection pooling mechanisms (e.g., HikariCP, pgbouncer), idle or excessive connections can strain database resources. Virtual Machine-Based Environments: AWS EC2 instances scale connection demand with the number of instances. Manual or automated tuning of connection pool parameters is essential to prevent exceeding database limits.
A pool of database connections can be created and then shared among the applications that need to access the database. The connection object obtained from the connection pool is often a wrapper around the actual database connection. The wrapper understands its relationship with the pool, and hides the details of the pool from the application.
Reliable Server Pooling (RSerPool) is a computer protocol framework for management of and access to multiple, coordinated (pooled) servers.RSerPool is an IETF standard, which has been developed by the IETF RSerPool Working Group [1] and documented in RFC 5351, RFC 5352, RFC 5353, RFC 5354, RFC 5355 and RFC 5356.
The article only mentions database connection pooling, but connection pooling is a generic concept that is not only used in conjunction with databases. Should the article mention that, perhaps? DeanHarding 06:35, 10 January 2008 (UTC) This article could probably be merged into Object pool. That article even mentions network and database ...
Under HTTP 1.0, connections should always be closed by the server after sending the response. [1]Since at least late 1995, [2] developers of popular products (browsers, web servers, etc.) using HTTP/1.0, started to add an unofficial extension (to the protocol) named "keep-alive" in order to allow the reuse of a connection for multiple requests/responses.
Several connection pool custom properties were added to support this resource failover and failback mechanism: failureThreshold - the number of consecutive getConnection() failures that must occur before automatic failover is invoked; alternateResourceJNDIName - the JNDI name of the alternate connection factory to use if automatic failover is ...
An example of this is the KPRB (Kernel Program Bundled) driver [16] supplied with Oracle RDBMS. "jdbc:default:connection" offers a relatively standard way of making such a connection (at least the Oracle database and Apache Derby support it). However, in the case of an internal JDBC driver, the JDBC client actually runs as part of the database ...
In computer science, a pool is a collection of resources that are kept in memory, ready to use, rather than the memory acquired on use or the memory released afterwards. In this context, resources can refer to system resources such as file handles , which are external to a process, or internal resources such as objects .
