Connection Validator

Product Specifications

Technical details and manufacturing context for Connection Validator

Definition

The Connection Validator is a critical sub-component of the Connection Pool Manager responsible for periodically checking the status of database connections in the pool. It ensures that connections are still alive, responsive, and ready to handle queries before they are assigned to applications, preventing errors from stale or broken connections. The validator operates by executing a lightweight test query (like 'SELECT 1') or checking connection metadata at configurable intervals. If a connection fails the validation test, it is marked as invalid, removed from the pool, and a new connection may be established to maintain the pool size. This component is typically deployed as part of a larger database connection management system in industrial software environments. It is designed to operate within specified parameters, including maximum connections (100–10000), validation interval (1–60 seconds), validation timeout (0.5–5 seconds), connection timeout (1–30 seconds), leak detection threshold (0.1–10%), CPU usage (1–5%), memory footprint (50–200 MB). These values are reference ranges and must be confirmed for the specific model and application. The component is subject to standards such as IEC 60068-2-1, IEC 60068-2-2, IEC 60068-2-78, IEC 60529, and IEC 61131-2, which serve as procurement and verification references. The validator's performance directly impacts the reliability of database-dependent applications, making it essential to configure validation intervals and timeouts appropriately. Regular monitoring of validation failures can indicate underlying database or network issues. For accurate specifications, consult the legal manufacturer or supplier.

Working Principle

The validator executes a lightweight test query, such as 'SELECT 1', or checks connection metadata at configurable intervals. If a connection fails the test, it is marked invalid and removed from the pool. A new connection may be established to maintain pool size. The validation interval and timeout are configurable to balance detection speed and resource usage.

Technical Parameters

Parameter	Typical range	Notes & selection driver
Maximum Connections	100–10000 connections	Higher values require more memory.
Validation Interval	1–60 s	Shorter intervals detect failures faster.
Validation Timeout	0.5–5 s	Must be less than connection timeout.
Connection Timeout	1–30 s	Longer timeouts may delay failover.
Leak Detection Threshold	0.1–10 %	Percentage of connections to test per cycle.
CPU Usage	1–5 %	Average under normal load.
Memory Footprint	50–200 MB	Depends on max connections.

Frequently Asked Questions

What does the Connection Validator do?

It periodically checks the health and validity of database connections in a connection pool, ensuring they are alive and responsive before being assigned to applications.

How does the validator test connections?

It executes a lightweight test query like 'SELECT 1' or checks connection metadata at configurable intervals. Failed connections are removed from the pool.

What parameters are important for configuration?

Key parameters include validation interval, validation timeout, connection timeout, and maximum connections. These must be set based on application requirements and confirmed with the manufacturer.

What standards apply to this component?

Relevant standards include IEC 60068-2-1, IEC 60068-2-2, IEC 60068-2-78, IEC 60529, and IEC 61131-2. These are references for verification, not proof of certification.
