Hello,
I have RHQ4.13.1 installed. I'm running 5 RHQ server instances clustered together (each on its own server) with a backend shared Oracle DB.
When I first completed the installation and configuration, the 'Alert Definition Templates' would load when I clicked on the link in the Admin panel of the GUI. Now, after a few months, when I click on the Alert Definition Templates, it simply says 'loading' and never loads. I see this error in the logs:
Caused by: java.lang.RuntimeException: com.datastax.driver.core.exceptions.UnavailableException: Not enough replica available for query at consistency ONE (1 required but only 0 alive)
at org.rhq.cassandra.schema.AbstractManager.getInstalledSchemaVersion(AbstractManager.java:193) [rhq-cassandra-schema-4.13.1.jar:4.13.1]
at org.rhq.cassandra.schema.VersionManager.checkCompatibility(VersionManager.java:266) [rhq-cassandra-schema-4.13.1.jar:4.13.1]
... 50 more
Any idea what I need to do to correct this?
Regards,
Barry
