Sun Java System Application Server Enterprise Edition 8.1 2005Q2 Upgrade and Migration Guide

ProcedureTo Upgrade a Cluster

  1. Copy the node-agent directory from DAS machine to client machine under install-dir/nodeagents/. For instance, if your DAS is installed on HostA and client machine name is HostB, the upgrade process would have created a node agent named “HostB-<domain_name>” as the node-agent for HostB. Hence copy HostB-<domain_name> from HostA<AS81_install_dir>/nodeagents/HostB-<domain_name> directory to HostB <AS81_install_dir>/nodeagents. After copying, delete the copied node agent directory under HostA.

  2. Edit nodeagent.properties file on client machine HostB under agent/config directory. Set agent.client.host to the client machine name. In this case it should be HostB.

  3. Edit das.properties file on client machine HostB under agent/config directory. Make sure agent.das.isSecure=false in das.properties file. It should be set to false if by default Application Server 7.x Administration Server was running on non secure port. If Application Server 7.x Administration Server was running on secure port, then it should be set to true.

  4. Start domain and start node agents on both DAS machine as well as client machines. This in turn will run the clustered instance.
