Server Management allows critical failures, or TVI alerts, to be reported
to Teradata immediately. Logging by Server Management is enabled by default, but can be
disabled by setting the value of the logger.useTviLogger property in agent.properties or daemon.properties to false.
Server Management errors that are reported by Data Mover are listed here by message ID number. All of the errors are critical.
- 4601001
- Synopsis: Daemon port in use.
- Meaning: The daemon port that is used for inbound socket connections from agents is in use by some other process.

- Probable Cause: The Data Mover repository server may be down or the repository may not have the correct list of tables.
- Recommendations: The Postgres instance being used as the Data Mover repository may not have logons enabled or it may need to be restarted. The Data Mover Daemon may need to be re-installed to update the repository with the correct list of tables as well.
- 4601003
- Synopsis: Daemon cannot connect to JMS broker.
- Meaning: The JMS broker is unreachable from the daemon.
- Probable Cause: ActiveMQ service may be down or daemon may have incorrect broker port/url configuration.

- 4601007
- Synopsis: The daemon repository purge task has timed out multiple times.
- Meaning: The Data Mover job respository is not being cleaned properly.

- 4602001
- Synopsis: Agent cannot connect to JMS broker.
- Meaning: The JMS broker is unreachable from the agent.
- Probable Cause: ActiveMQ service may be down or agent may have incorrect broker port/url configuration.

- 4603001
- Synopsis: Data Mover daemon component is unavailable.
- Meaning: The Data Mover Monitoring Service cannot detect the Data Mover daemon component.
- Probable Cause: The Data Mover daemon or the Data Mover daemon server may be down.
- Recommendations: Failover has been initiated to switch DM components to run on standby. Please investigate the root cause of the failure and run “dmcluster switchback” on the active server when the problem is addressed.
- 4603002
- Synopsis: Data Mover repository is unavailable.
- Meaning: The Data Mover monitoring service cannot detect the Data Mover repository database.
- Probable Cause: The Data Mover repository database may not be running or the Data Mover repository server may be down.

- 4603003
- Synopsis: All Data Mover agent components are unavailable.
- Meaning: The Data Mover monitoring service cannot detect any running Data Mover agent components.
- Probable Cause: All the Data Mover agent components may be down.
- Recommendations: Failover has been initiated to switch DM components to run on standby. Please investigate the root cause of the failure and run “dmcluster switchback” on the active server when the problem is addressed.
- 4603005
- Synopsis: Data Mover Sync Monitor is unavailable on active server.
- Meaning: The Data Mover Failover Monitoring service cannot detect the Sync Monitor, which tracks the replication progress when DM components are running on active.
- Probable Cause: The Sync Monitor may not be running.
- Recommendations: Check DM Sync log on active server. If replication service is broken, run 'dmcluster switchback' to reconfigure.
- 4603009
- Synopsis: ActiveMQ component is unavailable.
- Meaning: The Data Mover Failover Monitoring Service cannot detect the ActiveMQ component.
- Probable Cause: ActiveMQ component may not be running.
- Recommendations: Failover has been initiated to switch DM components to run on standby. Please investigate the root cause of the failure and run “dmcluster switchback” on the active server when the problem is addressed.
- 4603011
- Synopsis: Data Mover REST component is unavailable.
- Meaning: The Data Mover Monitoring Service cannot detect the Data Mover REST component.
- Probable Cause: Data Mover REST component may be down.
- Recommendations: Failover has been initiated to switch DM components to run on standby. Please investigate the root cause of the failure and run “dmcluster switchback” on the active server when the problem is addressed.
- 4603101
- Synopsis: Data Mover Daemon component is unavailable.
- Meaning: The Data Mover Failover Monitoring Service cannot detect the Data Mover Daemon component.
- Probable Cause: The Data Mover Daemon or the Data Mover Daemon server may be down.
- Recommendations: No failover will occur as DM components are already running on standby due to previous failover. Please investigate the root cause of the failover and run “dmcluster switchback” on the active server when the problem is addressed.
- 4603102
- Synopsis: Data Mover Repository is unavailable.
- Meaning: The Data Mover Failover Monitoring Service cannot detect the Data Mover Repository Database.

- 4604002
- Synopsis: Standby repository has too much data lagging.
- Meaning: The standby repository data replication is behind specified data lagging threshold.
- Probable Cause: The standby repository data replication is too slow or has stopped working.
