Lab 20–Configuring Application Redundancy9-13Lab 20 –Configuring RedundancyIntroductionInthislab, you will configure a second network connection in Windows for use as the Redundancy

Message Channel. Then, you will configure the Galaxy platforms and engines for redundancy. Finally,

you will create the hosting relationship, deploy the changes, and force a failover to confirm the

functionality.

ObjectivesUpon completion of this lab, you will be able to:Configure a secondary network connection in Windows as the Redundancy Message ChannelConfigure WinPlatform and AppEngine objects for redundancyCreate a deployment model for redundant enginesForce a failover on a redundant systemApplication Server2012

9-14Module 9–RedundancyConfigure Windows for RedundancyIn the following steps, you will configure a second network connection in Windows as the Redundancy

Message Channel (RMC). This will need to be done on both computers, where the first is the computer

where GRPlatformis deployed and the second is the computer where AOSPlatform1is t to the machine where the GRPlatformis installed [for the remote computer, this will be the

machine where the AOSPlatform1in installed].twork Connections(Start | Control Panel | Network and Sharing Center).hange adapter ys Learning Services
