Exceptions are logged after failover in a high-availability deployment

Issue:

After a failover to the standby server in a high-availability deployment of the TrueSight Presentation Server, exceptions related to replication are logged. These exceptions are of the following format:

org.infinispan.commons.CacheException: Problems invoking command.
java.lang.ClassCastException: ... cannot be cast to org.infinispan.metadata.Metadata
org.infinispan.commons.CacheException: java.lang.RuntimeException: Failure to marshal argument(s)
at org.infinispan.commons.util.Util.rewrapAsCacheException(Util.java:657)
at org.infinispan.remoting.transport.jgroups.CommandAwareRpcDispatcher.invokeRemoteCommand(CommandAwareRpcDispatcher.java:250)

Resolution:

1. Stop the standby node first and then stop the active node.
2. Log on to the primary host computer.
3. Take a backup of the installedDirectory\TrueSightPServer\truesightpserver\conf\ha\cache.conf file.

4. Using a text editor, edit and replace the <replicated-cache> tag in the cache.conf file with the following content:

   <replicated-cache name="defaultCache" mode="SYNC" remote-timeout="30000">
       <state-transfer await-initial-transfer="false"
           timeout="240000"
           enabled="true"
           chunk-size="10000"
       />
       
       <locking concurrency-level="1000" 
           striping="true"
           isolation="READ_COMMITTED" 
           write-skew="false"
       />
       
   </replicated-cache>

   
   

5. Save the cache.conf file.
6. Log on to the secondary host computer and perform steps 3 - 5.
7. Restart the previously active node first.
8. Ensure that the node is completely up and running and then restart the standby node.
