APS 11.1.2.3.502 diagnostic report failure

SOA DbAdapter lingo: java.sql.SQLException: setObject, Exception = 8

Retro Day - Workload Management in WebLogic Server

Quite recently, I stumbled across this older but still very relevant whitepaper on the workload management capabilities of  WebLogic Server.  Written by one of the key engineers at the time, who later went on to become an architectect, it explains the workings of the new work load management feature introduced into WebLogic Server at the time and covers the concepts of work-manager configuration and effect, work scheduling and prioritization, overload protection and  more.
