WAS failover and recovery

 

IBM WAS Network Deployment V5.1 failover and recovery is realized through the WebSphere Workload Management (WLM) mechanism. In addition, other clustering software such as HACMP, VERITAS Cluster Server, MC/ServiceGuard, Sun Cluster Server, and Microsoft Cluster Service can also be used to enhance appserver failover and recovery, especially because of aspects such as the two-phase transaction failover and transaction log recovery and the automatic recovery of failed hosts where WASs are running. We discuss all of these techniques.

For this chapter, we assume that you are using the IBM WAS Network Deployment V5.1 WLM functionality.

This chapter should be used in conjunction with Chapter 5, Plug-in workload management and failover and Chapter 6, EJB workload management.
