Where to find documented connection pool exhaustion limits for npss

The goal is to locate the official documentation that specifies how npss handles connection pool exhaustion, including any defined limits, thresholds, or configuration parameters that signal or prevent pool depletion. Understanding this behavior is essential for capacity planning and for setting up alerts when the pool approaches exhaustion.
Because the model has no specific knowledge of npss features, any description of its connection pool behavior would be speculative. Verification must rely on the product’s official release notes, administrator guides, or support articles to confirm whether such limits are documented and how they are expressed.

According to the product’s research guidance, the limits are described in the NPSS Administrator Guide (or equivalent manual) under a dedicated “Connection Pool” chapter.
npss --version or the product’s About dialog).docs/ directory of the installation.maxPoolSize or connectionPool.exhaustionLimit. The table lists its default value, allowed range, and any exhaustion‑threshold behavior.If you cannot locate the chapter, search the guide for the terms “connection pool exhaustion”, “maxPoolSize”, or “exhaustion limit”.
Use comments to ask for clarification. Post a solution as an answer.

NPSS does not impose a hard maximum on its JDBC connection pool; that boundary is defined by the underlying pool implementation (HikariCP, C3P0, Tomcat JDBC, etc.). The official NPSS admin guide points you to the pool’s configuration properties, which are the real source of exhaustion limits.
maxPoolSize, maxConnections, or connectionTimeout – these are the knobs that control pool size and wait behavior.In the NPSS installation directory, locate the datasource.properties (or equivalent) file. The properties you found in the guide should appear here, often prefixed by the pool vendor name (e.g., hikari.maxPoolSize).
Adjusting these values and monitoring the pool’s ActiveConnections vs. MaxConnections metrics will let you set alerts before exhaustion occurs.
