Problem: My Data aggregator keeps shutting down with the following error in the karaf.log
ERROR | t Monitor Thread | 2015-09-03 10:19:48,944 | shutdown | ase.heartbeat.DBStateManagerImpl 385 | ommon.core.services.impl | | DB heartbeat to host ><hostname of Db execeeded max non-success time of 300000
WARN | t Monitor Thread | 2015-09-03 10:19:48,944 | shutdown | ase.heartbeat.DBStateManagerImpl 726 | ommon.core.services.impl | | DB state for host <hostname of Db> changing from OK to DOWN
Cause: If there is no valid database connection then the Data Aggregator shuts down.
Environment: Data Aggregator and vertica db
Resolution: Check if the vertica database is up and running. If so, there should be a valid connectivity between the Data Aggregator and the vertica database.
The Data Aggregator waits for 5 minutes before shutting down itself without a valid connection to the database.
If you find the 5 minute shutdown timeout is too short (or too long), you
can modify it by adding a configuration file with the name
and place it in the %IM_DATA_AGGREGATOR%/apache-karaf-2.x.x/etc directory
In this file add the following property:
(change to 600000 for example to specify a 10 minute timeout).
