Repository error: "Aggregation ended with error and wait for next cycle"
In a cluster environment, if repository is configured with the physical host name and not with the cluster virtual name (typically this would be the node the agent was originally installed on), this error can occur after cluster failover. The repository fails to connect to the collector for the first time in order to retrieve the middleware connection info.
Please modify the repository XML configuration file located under ..\agents\SC_MSSQL\7.0\<host-instance>\quest_sc_rep\config\sc_rep_mngr.xml
The physical host name in the configuration file should be replaced with the cluster virtual name.
Restart the QAM Launcher service after the change.
