Configure for Tivoli Performance Analyzer high availability and disaster recovery
The Tivoli Performance Analyzer must always connect to the hub monitoring server. When you use the Hot Standby option, you can configure Tivoli Performance Analyzer Agent with the standby hub as the secondary monitoring server.
Since there can only be one Tivoli Performance Analyzer Agent in the Tivoli Monitoring environment (that is one Tivoli Performance Analyzer Agent per hub monitoring server) it is not possible to setup a secondary agent in Hot Standby mode. However, you can setup a second Tivoli Performance Analyzer Agent and keep it stopped, as long as the primary server is running. The secondary agent can only be started when the primary agent is stopped and disabled. The Tivoli Monitoring Administrator can perform the switch manually, or use Take Action commands. In both cases it is very important to ensure that only one agent is running at the same time. See Configure for Summarization and Pruning Agent high availability and disaster recovery for information on writing the Take Action command.
