Data Mover log files are moved to the /var/opt/teradata/datamover/logs directory as follows:
- dmDaemon.log
- dmAgent.log
- dmSync.log
- dmFailover.log
- upgrade_backup.log
During Data Mover installation and upgrade, the log files are preserved with up to 10 backups. For example, dmdaemon-postinstall.log backups are preserved as dm-daemon-postinstall.log.1, dmdaemon-postinstall.log.2, and so on, up to dmdaemon-postinstall.log10, where the most recent file is dmdaemon-postinstall.log.1. The following log files, with date and timestamp details added, are preserved during installations and upgrades:
- /tmp/dmdaemon-postinstall.log
- /tmp/dmagent-postinstall.log
- /tmp/put-dmschemaupgrade.log
- /tmp/put-dmlistagents.log
- /var/opt/teradata/datamover/logs/upgrade_backup.log
Log files for DSA are located in the /var/opt/teradata/dsa/logs directory.
Log files for the Data Mover RESTful API are located in the /var/opt/teradata/datamover/logs directory as tdmRest.log file.
The log file /tmp/dmdaemon-preupgradecheck.log captures the output of the Data Mover pre-upgrade check.
