Beschreibung

max_connections must be sized from instance capacity, per-connection memory, application pool limits, administrative reserve, and measured peak concurrency, and monitored with current and rejected connections.

So wird geprüft

Prüfmethode: Manuelle Prüfung

Diese Empfehlung kann nicht automatisch geprüft werden. Ein Scan führt sie mit diesen Anweisungen auf, wenn Sie --include-manual übergeben.

SHOW GLOBAL VARIABLES LIKE 'max_connections'; SHOW GLOBAL STATUS LIKE 'Max_used_connections'; SHOW GLOBAL STATUS LIKE 'Threads_connected'; SHOW GLOBAL STATUS LIKE 'Connection_errors_max_connections'; Review a representative peak period and confirm an approved capacity calculation, coordinated application/Gateway pool totals, an administrative reserve, and alerts for utilization and rejected connections.

So wird behoben

Behebungsmethode: Anleitung oder Infrastruktur-Patch

Calculate the approved limit from workload and memory evidence, coordinate application pool limits, and persist it through a TDSQL custom parameter template. Do not apply a generic value such as 2048 without capacity testing.
