Third-Party Apps Tackle Web Services Reliability
Performance management products from third parties are taking on crucial Web services reliability issues.As Web services become bigger pieces of an organizations technology infrastructure, the same kind of discipline that keeps core database servers and directory servers running at a reliability of four or five nines needs to be applied to Web services servers. If it cant be, then the technology cant be depended upon to deliver all day, every day at acceptable response times. Performance management, in fact, has long been an Achilles heel of application servers in general. Of the top four application servers by market shareBEA Systems Inc.s BEA WebLogic Server, IBMs WebSphere, Oracle Corp.s Oracle9i Application Server and Sun Microsystems Inc.s Sun ONE Application Serveronly WebSphere provides anything other than shallow, mostly cross-server quality-of-service measurements.
Tivoli Performance Viewer, included in WebSphere, lets users view detailed usage and response time statisticsdown to the individual object leveland log statistics to disk for historical analysis.
