How can I diagnose intermittent connection pool exhaustion in a .NET app using ADO.NET with SQL Server on Glitch?
The goal is to identify why a connection pool intermittently runs out of available connections in an ADO.NET‑based application hosted on Glitch, while using a specific pooling feature such as Max Pool Size. The application exhibits sporadic time‑outs and exceptions despite seemingly normal traffic, making it unclear whether the exhaustion stems from unreturn
glitchVB.NET ADO.NET Transactions and Cross-Database DDL Rollback Consistency
Integration Boundary VB.NET applications using System.Transactions.TransactionScope or explicit DbTransaction objects rely on ADO.NET's common abstraction layer to coordinate work across SQL Server, PostgreSQL, and Oracle. The abstraction promises a single Rollback() call that undoes all enlisted operations, but the underlying providers diverge sharply when
visualbasicADO.NET Connection Pool Max Pool Size Limits
ADO.NET utilizes connection pooling to minimize the overhead of establishing physical database connections. By default, the pool manages connections based on the exact connection string provided, and the Max Pool Size attribute defines the upper limit of physical connections allowed per pool. When an application reaches this limit and all connections are cur
