Data replication progress between active repository and standby repository may have slowing, if the slowing exceeded user-specified lag threshold, TVI alert 4604002 is triggered. For information about system slowing and alerts, see Understanding Replication Lag.

  1. On the standby server, go to /var/opt/teradata/postgres/data/log/postgresql.log.* and fix any errors listed that are blocking data replication.
  2. If no error found in postgresql.log.* and the sequence number in the dm_sequences table on the standby is still lagging, check and fix the following:
    • If the lagging threshold is set too low, increase the sync.data.lagging.threshold in sync.properties
    • Check network speed
    • Reconfigure the synchronization service
