When you start the slave synchronization service, dmSyncSlave.json is created in the specified path as defined by the value of sql.log.directory in sync.properties. The service writes the SQL updates to the file /var/opt/teradata/datamover/logs/dmSyncSlave.json. The slave synchronization service writes SQL statements that the master sends to dmSyncSlave.json, after which the slave service executes the SQL statements using another service on the slave repository. After all SQL statements are executed, dmSyncSlave.json is deleted. If any SQL statements fail to execute, a TVI alert is triggered.
