Summary :
SAP Note addresses an error where connections to a DataSource via ConnectionFactoryImpl fail to establish in a SAP J2EE Engine. Identification of this issue hinges on three primary causes: cached connections within system threads, insufficient pool sizes of specific adapters due to high system load, and inadequate waiting times for connection availability relative to current pool sizes. Solutions include using Connector Service commands to check cached connections, adjusting pool sizes, and increasing connection wait times. Techniques such as switching to debug mode and using "list_conns" command are suggested for diagnosis and troubleshooting. Performance improvements may involve telnet connections to SAP J2EE Engine, employing DBPool Service commands, and configuring DataSource properties based on observed connection utilizations and system load impacts.
